  • PGT-M Testing in Thailand: Eligibility Questions for International Patients

    PGT-M (preimplantation genetic testing for monogenic conditions) is a targeted test. It is usually considered when a specific inherited condition and a specific genetic change (mutation) have already been identified in the family. For international patients, eligibility is not a single yes-or-no answer. It depends on your genetic history, the laboratory’s ability to build a reliable test, and the clinic’s own policies. This guide explains the questions to ask and the steps to plan, without giving legal or medical conclusions.

    At a glance

    • PGT-M is not a general screening test; it is designed around a known familial mutation.
    • Most pathways begin with genetic counselling and a prior genetic workup, often before you contact a clinic in Thailand.
    • Eligibility is assessed case by case and clinic policies may vary.
    • You will likely need to confirm document, cost, travel and legal categories directly with the treating clinic or relevant authority.
    • PGT-M does not guarantee a pregnancy, a live birth or a child without the condition.

    What PGT-M is and what it is not

    PGT-M looks for a known, specific genetic change in embryos created through IVF. It is different from PGT-A, which looks at chromosome number, and from PGT-SR, which is used when there is a known structural chromosome rearrangement. Because PGT-M is targeted, it usually requires that the exact mutation has already been found in your family through genetic testing.

    PGT-M is not a guarantee. It cannot ensure a pregnancy, a live birth or a child unaffected by the condition. It also cannot detect every possible genetic or health issue. Results can be affected by laboratory factors, and some embryos may give an unclear result. Your clinic should explain the limits in your specific situation.

    Why a known familial mutation usually matters

    To design a PGT-M test, a laboratory generally needs to know what it is looking for. That usually means a confirmed mutation in a family member, or in you or your partner. Without that information, a laboratory may not be able to build a reliable test. In some situations, a clinic may discuss additional workup, but this is a clinical decision and not something to assume.

    If no mutation has been identified, the first step is usually genetic counselling and testing in your home country or with a genetics service. This is often called a prior genetic workup. It can take time, and it may need to be completed before a PGT-M referral can move forward.

    Common eligibility questions international patients ask

    Do I need a referral from a geneticist or doctor?

    Many clinics prefer or require a referral from a clinical geneticist, genetic counsellor or specialist who has already assessed the family condition. This helps the clinic understand the mutation and the inheritance pattern. Requirements vary, so ask the clinic what referral information they need and in what format.

    Can I start PGT-M if I have not had genetic testing?

    Usually not, because PGT-M is built around a known mutation. If you have not had genetic testing, a clinic may ask you to complete that first. In some cases, a clinic may discuss whether testing is possible, but this is a clinical and laboratory decision. Do not assume it can be arranged after you arrive.

    Does the type of inherited condition affect eligibility?

    Different conditions and different mutations can affect how a test is designed. Some may be more straightforward than others. The laboratory needs to be able to build a reliable test for your specific mutation. This is a technical assessment, and it is one reason why eligibility is case by case.

    Can both partners be carriers?

    If both partners carry a mutation for the same condition, the inheritance pattern and the testing strategy may be different. This is a clinical question for a genetic counsellor or specialist. The clinic will need to review both partners’ genetic information.

    Is PGT-M available for every inherited condition?

    No. Availability depends on the laboratory’s ability to design a test for the specific mutation and on the clinic’s policies. Some conditions may be more difficult to test for than others. Ask the clinic whether they have experience with your specific condition and mutation.

    Do clinic policies vary?

    Yes. Clinics may have different requirements for referral, prior workup, counselling, documentation and eligibility. Some may accept international patients directly; others may require a local or remote genetics consultation first. Always confirm the clinic’s own policy.

    How the referral and eligibility process often works

    The exact steps depend on your situation and the clinic. A typical sequence may look like this:

    1. Genetic counselling and testing in your home country. A clinical geneticist or genetic counsellor confirms the condition and the specific mutation.
    2. Gather your genetic documentation. This may include test reports, family history and a summary letter from your genetics team.
    3. Contact a clinic in Thailand. Ask whether they offer PGT-M for your condition and what they need to assess eligibility.
    4. Laboratory review. The clinic’s laboratory reviews whether a reliable test can be designed for your mutation.
    5. Clinical review and counselling. A specialist may discuss the inheritance pattern, the limits of PGT-M and alternatives.
    6. Decision and planning. If the pathway is possible, the clinic explains the IVF process, timelines and what to confirm before travel.

    This is a general outline, not a promise of eligibility. Some steps may be combined, repeated or not possible in your case.

    Questions to ask a clinic about PGT-M eligibility

    • Do you offer PGT-M for my specific condition and mutation?
    • What prior genetic workup do you require, and in what format?
    • Do you need a referral from a geneticist or genetic counsellor?
    • How do you assess whether a laboratory can design a test for my mutation?
    • What counselling do you provide before and after testing?
    • What are the limits of PGT-M in my situation?
    • What alternatives should I consider?
    • What documents, costs and travel arrangements should I confirm before planning?
    • What is your policy if the test cannot be designed or gives an unclear result?

    Practical planning categories to confirm

    Because requirements can change and vary by clinic, treat the following as categories to confirm directly rather than fixed rules:

    • Documents: genetic test reports, referral letters, identification and any clinic-specific forms.
    • Costs: consultation, laboratory test design, IVF cycle, PGT-M testing, medication, travel and accommodation. Ask for a written breakdown.
    • Travel and timing: how long you may need to stay, how many visits are involved and whether monitoring can be done locally.
    • Legal and regulatory: what is permitted in Thailand and in your home country, and what you need to confirm with the relevant authority.
    • Follow-up: how results are communicated, what happens to stored embryos and what support is available.

    Alternatives and limits to discuss

    PGT-M is one option among several. Depending on your situation, alternatives may include prenatal testing, accepting the natural chance of inheritance, using donor gametes, or choosing not to pursue testing. Each option has different implications, and none is right for everyone. A genetic counsellor or specialist can help you weigh them.

    PGT-M also has limits. It may not be possible for every mutation. It may not detect all genetic issues. It does not guarantee a healthy child. Some embryos may be affected, unaffected or give an unclear result. Your clinic should explain what an unclear result could mean for you.

    Next steps

    1. Speak with a genetic counsellor or clinical geneticist about your family condition and whether PGT-M is relevant.
    2. Collect your genetic test reports and a summary letter.
    3. Contact clinics in Thailand to ask about PGT-M eligibility for your specific mutation.
    4. Ask for written information about documents, costs, timelines and limits.
    5. Confirm legal and travel requirements with the relevant authority and the clinic.
    6. Take time to consider alternatives and make a decision that fits your values.

    Frequently asked questions

    Can I get PGT-M in Thailand without a known mutation in my family?

    PGT-M is usually designed around a known, specific mutation. Without that information, a laboratory may not be able to build a reliable test. Some clinics may discuss additional workup, but this is a clinical decision. It is best to speak with a genetic counsellor or specialist first.

    Do I need a referral from a geneticist to start PGT-M in Thailand?

    Many clinics prefer or require a referral from a clinical geneticist, genetic counsellor or specialist. Requirements vary by clinic. Ask the clinic what referral information they need and in what format before you plan.

    Is PGT-M available for all inherited conditions?

    No. Availability depends on whether a laboratory can design a reliable test for your specific mutation and on the clinic's policies. Some conditions may be more difficult to test for than others. Confirm with the clinic whether they have experience with your condition.

    Does PGT-M guarantee a healthy baby?

    No. PGT-M cannot guarantee a pregnancy, a live birth or a child without the condition. It also cannot detect every possible genetic or health issue. Your clinic should explain the limits and what results may mean in your situation.

    What should I confirm with a clinic before travelling to Thailand for PGT-M?

    Confirm the clinic's eligibility policy, required documents, costs, expected timeline, travel arrangements and legal considerations. Ask for a written breakdown and clarify what happens if the test cannot be designed or gives an unclear result.

  • PGT-A Testing in Thailand: Who May Benefit and What It Cannot Tell You

    PGT-A (preimplantation genetic testing for aneuploidy) is a laboratory test performed on a small sample of cells from an embryo created through IVF. It counts chromosomes to identify embryos with an abnormal number, such as an extra or missing chromosome. It does not diagnose a specific disease, measure embryo quality, or guarantee a pregnancy. In Thailand, as elsewhere, PGT-A is one option your fertility team may discuss, not a required step for every IVF cycle.

    At a glance

    • PGT-A screens for chromosome number, not for gene mutations or structural rearrangements.
    • It is usually considered when the chance of chromosome errors is higher, but individual suitability is a clinical judgment.
    • A “normal” result does not guarantee a healthy pregnancy or baby.
    • An “abnormal” result does not always mean the embryo could never produce a pregnancy, but it does change the information available.
    • Costs, timelines, and legal or documentation requirements vary and should be confirmed directly with your clinic and relevant authorities.

    What PGT-A actually screens

    PGT-A looks at the number of chromosomes in the embryo. Human embryos should have 46 chromosomes, arranged in 23 pairs. An embryo with an extra or missing chromosome is called aneuploid. Aneuploidy becomes more common with increasing maternal age, but it can occur at any age.

    The test is typically done on a few cells removed from the trophectoderm, the outer layer of a blastocyst-stage embryo. The embryo itself is not changed by the biopsy. Results are reported as euploid (normal chromosome number), aneuploid (abnormal chromosome number), or sometimes mosaic (a mix of normal and abnormal cells). Some clinics also report a result as inconclusive, meaning the sample did not give a clear answer.

    PGT-A does not look for single-gene disorders such as cystic fibrosis or Huntington’s disease. It does not look for structural chromosome rearrangements such as translocations. Those are addressed by different tests: PGT-M for monogenic disorders and PGT-SR for structural rearrangements. If you are considering PGT-A, it is worth asking your clinic which test is relevant to your situation.

    Who may be offered PGT-A

    PGT-A is not automatically recommended for everyone. Guidelines from professional fertility societies generally suggest it may be considered in specific circumstances, but they do not mandate it as a routine add-on for all IVF cycles. Your fertility specialist can explain whether it is likely to add useful information in your case.

    Situations where PGT-A may be discussed include:

    • Advanced maternal age. The chance of aneuploidy increases with age, so some clinics offer PGT-A to help select embryos for transfer.
    • Recurrent pregnancy loss. If you have had multiple miscarriages, your doctor may suggest PGT-A as part of an evaluation, though it does not explain all causes of loss.
    • Repeated implantation failure. When several IVF transfers have not led to a pregnancy, PGT-A may be considered, but evidence for its benefit in this situation is not uniform.
    • Previous pregnancy with a chromosome abnormality. A prior aneuploid pregnancy may prompt a discussion about screening future embryos.
    • Patient preference after counseling. Some people choose PGT-A to gain more information before transfer, even without a specific risk factor.

    PGT-A is not a substitute for standard prenatal testing. It cannot replace ultrasound, blood tests, or diagnostic procedures during pregnancy. It also does not improve the quality of an embryo; it only provides information about chromosome number.

    What PGT-A cannot tell you

    Understanding the limits of PGT-A is as important as understanding its purpose. The test has several important limitations.

    • It does not guarantee a pregnancy. A euploid embryo may still fail to implant or may result in a miscarriage for reasons unrelated to chromosome number.
    • It does not guarantee a healthy baby. Many health conditions are caused by factors other than chromosome number, including gene mutations, environmental influences, and events during pregnancy.
    • It does not detect all chromosome problems. Some small deletions or duplications, and some structural rearrangements, may not be seen with standard PGT-A.
    • It can produce mosaic results. A mosaic result means the biopsy found a mix of cells with different chromosome numbers. The meaning of mosaicism is still an area of active research, and counseling can be complex.
    • It can be inconclusive. Sometimes the sample does not yield enough DNA for a clear result.
    • It does not measure embryo potential beyond chromosome number. Two embryos with the same chromosome result can have different developmental potential for reasons not captured by the test.

    Because of these limits, PGT-A is best understood as one piece of information among many. It does not replace a thorough fertility evaluation or a discussion of all available options.

    PGT-A compared with PGT-M and PGT-SR

    PGT-A is part of a family of preimplantation genetic tests. Each has a different purpose.

    Test What it looks for Typical situation
    PGT-A Extra or missing chromosomes (aneuploidy) Advanced maternal age, recurrent loss, repeated implantation failure, or patient preference
    PGT-M Specific single-gene disorders Known inherited condition in the family
    PGT-SR Structural chromosome rearrangements Known translocation or similar rearrangement

    If you have a known genetic condition in your family, PGT-M may be more relevant than PGT-A. If you carry a balanced translocation, PGT-SR may be discussed. Your clinic can help determine which test, if any, fits your situation.

    Alternatives and additional considerations

    PGT-A is not the only way to approach embryo selection. Some people choose to transfer embryos without PGT-A and rely on standard embryo grading, which looks at appearance under a microscope. Others may consider transferring a mosaic embryo after counseling, as some mosaic embryos can lead to healthy births. These decisions are highly individual and should be made with your fertility team.

    It is also important to consider the practical aspects. PGT-A adds cost, requires embryo biopsy and freezing, and may extend the time to transfer. Not all embryos survive biopsy or thawing. These are not reasons to avoid PGT-A, but they are factors to weigh.

    Questions to ask your clinic

    If you are considering PGT-A in Thailand, asking clear questions can help you make an informed decision. Consider asking:

    • What is the specific reason PGT-A is being recommended in my case?
    • What are the alternatives, and what are their trade-offs?
    • How does your laboratory handle mosaic or inconclusive results?
    • What are the costs, including biopsy, testing, and embryo storage?
    • What are the success rates for my age group and diagnosis at your clinic?
    • What paperwork or legal requirements apply to me as an international patient?
    • What happens to embryos that are not transferred?

    These questions can help you understand the clinical and practical picture. They are not a substitute for personalized medical advice.

    Next steps

    If you are researching PGT-A, start by clarifying your own priorities and medical history. Gather any relevant records, such as previous IVF cycles, miscarriage history, or genetic test results. Then schedule a consultation with a fertility specialist who can review your situation and explain whether PGT-A is likely to be useful for you. You can also read more about PGT in Thailand and explore our guides for related topics. If you have general questions, our FAQ may help.

    Remember that PGT-A is a tool, not a promise. It can provide useful information, but it cannot guarantee an outcome. A thoughtful discussion with your clinic is the best way to decide whether it fits your path.

    Frequently asked questions

    Does PGT-A guarantee a healthy baby?

    No. PGT-A screens for chromosome number, but it cannot detect all genetic or health conditions. Many factors affect pregnancy and child health, and a euploid result does not guarantee a healthy baby.

    Who is a candidate for PGT-A?

    PGT-A may be discussed for people with advanced maternal age, recurrent pregnancy loss, repeated implantation failure, or a previous aneuploid pregnancy. Some people also choose it without specific risk factors. Suitability is a clinical judgment, so talk with your fertility specialist.

    What is the difference between PGT-A, PGT-M, and PGT-SR?

    PGT-A looks at chromosome number (aneuploidy). PGT-M looks for specific single-gene disorders. PGT-SR looks for structural chromosome rearrangements. Your clinic can help determine which test, if any, is relevant for you.

    Can PGT-A detect all chromosome abnormalities?

    No. PGT-A detects extra or missing whole chromosomes, but it may not detect small deletions or duplications, and some structural rearrangements may be missed. It also cannot detect gene mutations.

    What does a mosaic PGT-A result mean?

    A mosaic result means the biopsy found a mix of cells with different chromosome numbers. The implications are complex and still being studied. Your clinic can explain what a mosaic result might mean for your specific situation.

  • PGT-A Testing Cost in Thailand: How to Read a Quotation as an International Patient

    If you are comparing PGT-A quotations from clinics in Thailand, the headline number is rarely the full story. A quotation may cover the genetic laboratory fee but not the embryo biopsy, or it may include a set number of embryos and charge separately for additional ones. Because PGT-A is usually part of an IVF cycle, the quotation may also sit alongside IVF fees, medication, monitoring, and storage. This guide explains the categories that commonly appear in a PGT-A quotation, the boundaries that are often left unstated, and the questions that help you compare quotes on equal terms. It does not provide prices, because those depend on the clinic, the laboratory, and your individual treatment plan.

    At a glance

    • PGT-A is a laboratory test performed on embryos created during IVF, so its cost is usually quoted alongside IVF costs, not instead of them.
    • A quotation may separate the biopsy procedure, the genetic laboratory analysis, and any embryo storage or re-biopsy fees.
    • Some quotes are per embryo, some are per cycle, and some combine both. Ask which model applies.
    • Written boundaries matter more than a single total, because they show what would trigger an additional charge.
    • Cost is only one part of the decision. Ask how results are reported, what happens if no embryo is suitable for testing, and how the clinic communicates with patients abroad.

    Why a PGT-A quotation is not a single price

    PGT-A, or preimplantation genetic testing for aneuploidy, is a screening test that examines the number of chromosomes in an embryo. It is not a treatment on its own. It is performed in a laboratory after embryos have been created through IVF and usually after they have reached a certain stage of development. Because of this, the cost of PGT-A is layered on top of the IVF cycle rather than replacing any part of it.

    For international patients, this layering is where confusion often starts. A clinic may present one figure for the IVF cycle and another for PGT-A, or it may present a package that combines several services. Neither approach is wrong, but they are not directly comparable unless you know what each figure covers. The useful question is not only “How much is PGT-A?” but “What exactly is included in this quotation, and what would cause the cost to change?”

    Common cost components in a PGT-A quotation

    The exact structure varies by clinic and laboratory. The categories below are the ones most often separated in quotations, and they are the ones worth checking line by line.

    Embryo biopsy

    Before the genetic laboratory can analyse an embryo, a small sample of cells must be removed. This is the biopsy. In some quotations the biopsy is included in the PGT-A fee; in others it is billed as a separate procedure. It may also be charged per embryo, which means the total depends on how many embryos are suitable for biopsy. Ask whether the biopsy fee is included, and whether it is charged per embryo or per cycle.

    Genetic laboratory analysis

    This is the part most people think of as “the PGT-A test.” It covers the laboratory work that examines the biopsy sample and produces a result. The fee may be quoted per embryo, per batch of embryos, or as a flat fee for the cycle. If the quotation is per embryo, ask what happens if more embryos are available than expected, or fewer.

    Embryo storage

    Embryos that are biopsied are usually frozen while waiting for results, and they may remain in storage afterwards. Storage is often billed separately and may be charged monthly, annually, or for an initial period. Ask when storage begins, how it is billed, and what happens if you need to continue storage longer than the initial period.

    Re-biopsy or repeat testing

    Occasionally a sample may not give a clear result, and the clinic may discuss whether a repeat biopsy or repeat analysis is possible. This is not a routine part of every cycle, but it is a boundary worth clarifying in advance. Ask whether a repeat test would be charged again, and under what circumstances.

    IVF cycle costs that sit alongside PGT-A

    PGT-A does not replace the IVF cycle. Monitoring, egg retrieval, laboratory fertilisation, medication, and embryo freezing may all be quoted separately. If you are comparing PGT-A quotations, make sure you are also comparing the IVF quotation, because a lower PGT-A figure may sit next to a higher IVF figure, or vice versa.

    What a quotation may leave out

    Quotations are usually written for a typical pathway, and real cycles do not always follow the typical pathway. The following items are commonly excluded or only partly covered. They are not hidden fees in every case, but they are the questions that most often change the final amount.

    • Number of embryos tested. If the quote is per embryo, the total depends on how many embryos are available and suitable for biopsy.
    • Medication. Fertility medication is often quoted separately and can vary with your response to treatment.
    • Additional monitoring or visits. Extra scans, blood tests, or consultations may be billed individually.
    • Storage beyond an initial period. Storage is often time-limited in the quotation.
    • Shipping or transport of samples. If samples are sent to an external laboratory, transport may be a separate line.
    • Administrative or coordination fees. Some clinics charge for international patient coordination, translation, or records handling.
    • Travel, accommodation, and living costs. These are rarely included in a medical quotation but are part of your overall budget.

    How to compare quotations fairly

    Comparing quotations is easier when you use the same criteria for each one. The table below lists the questions that turn a headline figure into a comparable set of boundaries. It does not contain prices, because those must come from the clinic in writing.

    Question Why it matters
    Is the PGT-A fee per embryo or per cycle? Determines how the total changes with the number of embryos.
    Is the biopsy included? Biopsy may be billed separately or per embryo.
    Is embryo storage included, and for how long? Storage often continues after the test and may be billed over time.
    What happens if a sample needs to be repeated? Clarifies whether a repeat test would be charged again.
    Are IVF, medication, and monitoring included? PGT-A sits alongside IVF costs, not instead of them.
    Are there administrative or coordination fees? International patient services may be billed separately.
    How and when will results be communicated? Affects planning and follow-up, even if it is not a cost line.

    Questions to ask a clinic before you commit

    These questions are designed to produce written answers you can compare. Ask for them in writing, and keep the replies with your quotation.

    1. Can you send a written quotation that separates the IVF cycle, the PGT-A laboratory fee, the biopsy, and storage?
    2. Is the PGT-A fee charged per embryo, per cycle, or in another way?
    3. What is the maximum number of embryos covered by the quotation, if any?
    4. What would cause the quotation to increase, and how would I be told before the increase happens?
    5. Is embryo storage included, and if so, for how long and at what point does it renew?
    6. If a sample cannot be analysed, what are the options and would there be an additional charge?
    7. Which costs are paid to the clinic and which, if any, are paid to an external laboratory?
    8. What is your process for communicating results and next steps to patients who are not in Thailand?
    9. Are there any administrative, coordination, or records fees for international patients?
    10. What is your cancellation and refund policy if the cycle changes or is stopped?

    Planning your budget beyond the quotation

    A PGT-A quotation is one part of a larger budget. International patients usually also plan for flights, accommodation, local transport, meals, and time away from work. Some clinics may ask for a deposit before treatment starts, and payment schedules can vary. Ask how and when payments are due, what currency is used, and whether any bank or transfer fees apply. These are practical boundaries that affect your total outlay even though they are not medical fees.

    It is also worth asking how the clinic handles communication while you are abroad. A clear point of contact, a written summary of your plan, and an agreed way to share results can reduce uncertainty. These are not cost items, but they are part of comparing clinics as a whole.

    What PGT-A can and cannot tell you

    PGT-A is a screening test. It provides information about the number of chromosomes in the cells sampled, and it is used to help decide which embryos may be considered for transfer. It does not guarantee a pregnancy, a live birth, or a healthy child, and it does not test for every possible genetic condition. A clinic should explain the limitations of the test, what a result can and cannot show, and how the result fits into your wider treatment plan. If a quotation is presented as a guarantee of an outcome, that is a reason to ask more questions rather than fewer.

    Next steps

    Start by requesting written quotations from the clinics you are considering, using the same list of questions for each. Compare the boundaries, not just the totals. If a quotation is unclear, ask for it to be rewritten with the inclusions and exclusions stated separately. You can read more about the wider cost picture in our guide to PGT-A cost in Thailand and our overview of IVF cost in Thailand. For general planning tools and background reading, see our patient resources, and if you would like help organising your questions, you can contact us.

    Frequently asked questions

    Does a PGT-A quotation in Thailand usually include the embryo biopsy?

    It varies. Some clinics include the biopsy in the PGT-A fee, while others bill it separately or per embryo. Ask for the quotation to state clearly whether the biopsy is included, and whether it is charged per embryo or per cycle.

    Is PGT-A charged per embryo or per cycle?

    Both models exist. A per-embryo fee means the total depends on how many embryos are available and suitable for testing. A per-cycle fee is a single charge for the cycle. Ask which model applies and what happens if the number of embryos differs from what was expected.

    What costs might appear in addition to the PGT-A fee?

    Common additions include IVF cycle costs, medication, monitoring, embryo storage, administrative or coordination fees, and travel. The exact list depends on the clinic. Ask for a written quotation that separates each category so you can see what is included.

    Can I get a fixed total price for PGT-A before I start?

    Some clinics may offer a package, but many quotations are estimates because the number of embryos and your response to treatment can vary. Ask what would cause the quotation to change and how you would be informed before any additional charge is made.

    What should I do if a quotation is unclear?

    Ask the clinic to rewrite it with inclusions and exclusions stated separately. Use the same questions for each clinic you contact so you can compare like with like. Keep all written replies with your quotation for reference.

  • PGT for Family Balancing in Thailand: What International Patients Should Know

    PGT for family balancing in Thailand is a topic where policy, clinical practice, and patient expectations meet. In simple terms, preimplantation genetic testing (PGT) can include analysis of sex chromosomes, and some international patients ask whether this can be used to influence the sex of a future child. Thailand has its own legal and regulatory framework for assisted reproduction, and individual clinics also set their own policies. Because rules and clinic practices can change, the most reliable approach is to confirm current requirements directly with the treating clinic and, where needed, with the relevant Thai authority. This article explains the key distinctions, uncertainties, and questions to ask so you can plan responsibly.

    At a glance

    • PGT is a laboratory test on embryos during IVF; it can include sex chromosome information.
    • Family balancing generally means trying to have a child of a particular sex for family composition reasons.
    • Thailand regulates assisted reproduction, but specific rules and clinic policies may vary and can change.
    • International patients should confirm eligibility, documentation, and legal requirements before traveling.
    • No outcome is guaranteed; PGT cannot ensure a pregnancy, a live birth, or a child of a specific sex.

    What is PGT and how does it relate to family balancing?

    Preimplantation genetic testing (PGT) is an optional laboratory step during in vitro fertilization (IVF). A small number of cells are removed from an embryo and tested. PGT can be used for different purposes, such as screening for chromosomal abnormalities or testing for a specific inherited condition. Some forms of PGT also report the sex chromosomes of the embryo.

    Family balancing, sometimes called sex selection for family composition, is when patients hope to have a child of a particular sex because they already have children of one sex or for other personal reasons. When PGT includes sex chromosome information, it may be possible to identify embryos with XX or XY chromosomes. However, this is a medical procedure with limitations, and it is not available for every patient or in every clinic.

    Is PGT for family balancing legal in Thailand?

    Thailand has laws and regulations that govern assisted reproductive technology. These rules address several aspects of IVF and PGT, including who may access treatment and under what conditions. The legal status of using PGT specifically for family balancing is a matter that depends on how the law is interpreted and applied, and it may also be affected by clinic policy.

    Because legal and regulatory details can change, this article cannot state a definitive legal conclusion. Instead, you should treat this as a question to confirm with the clinic you are considering and, if necessary, with a qualified Thai legal professional or the relevant health authority. Do not rely on outdated forum posts or general websites for legal advice.

    What do clinics in Thailand typically require?

    Clinics in Thailand that offer PGT for international patients usually have their own internal policies. These policies may cover:

    • Whether the clinic offers PGT for family balancing at all.
    • What medical or non-medical criteria patients must meet.
    • What documents are required, such as passports, marriage certificates, or medical records.
    • Whether counseling is mandatory before proceeding.
    • How the clinic interprets Thai law and professional guidelines.

    Because these requirements are clinic-specific and can change, you should ask directly. A clinic may decline to offer family balancing even if it offers PGT for other reasons. It is also possible that a clinic will offer PGT for medical reasons but not for family balancing.

    Key distinctions: medical PGT vs. family balancing

    It helps to separate two ideas that are sometimes mixed together:

    • Medical PGT: Testing embryos for chromosomal abnormalities or specific genetic conditions to help reduce the risk of passing on a serious inherited disease or to improve IVF outcomes. In some cases, sex chromosome information is a byproduct of the test.
    • Family balancing: Using PGT specifically to choose the sex of an embryo for non-medical reasons. This is the area where legal and ethical questions are most prominent.

    Some countries permit medical PGT but restrict or prohibit family balancing. Thailand’s approach may differ, and clinic policies may be stricter than the law. Always ask which category your request falls into and what the clinic’s policy is.

    What international patients should confirm before planning

    If you are considering PGT for family balancing in Thailand, use the following checklist as a starting point. Treat each item as a question to confirm, not as a guarantee.

    1. Legal and regulatory status: Ask the clinic how it interprets current Thai law and whether family balancing is permitted under its license.
    2. Clinic policy: Confirm whether the clinic offers PGT for family balancing and what its specific conditions are.
    3. Eligibility criteria: Ask about any age, medical, or family history requirements.
    4. Required documents: Ask what identification, marriage, or medical records you need to provide.
    5. Counseling: Ask whether genetic counseling or psychological counseling is required or recommended.
    6. Costs: Request a written breakdown of all fees, including IVF, PGT, medications, monitoring, and any additional charges. Do not rely on verbal estimates.
    7. Travel and logistics: Ask how many days you need to stay, how many clinic visits are required, and whether any steps can be done in your home country.
    8. Success and limitations: Ask about the clinic’s general IVF success rates, but understand that no clinic can guarantee a specific outcome or a child of a particular sex.
    9. Follow-up: Ask what happens after treatment, including any follow-up testing or support.

    Questions to ask a clinic about PGT and family balancing

    When you contact a clinic, consider asking these questions in writing so you have a record of the answers:

    • Does your clinic offer PGT for family balancing? If so, under what conditions?
    • What is your understanding of the current Thai legal position on this?
    • What documents do I need to provide as an international patient?
    • Is counseling required before PGT?
    • What are the costs, and what do they include?
    • What are the limitations and risks of PGT?
    • Can you provide a treatment timeline that includes travel and monitoring?
    • What happens if no embryos are suitable for transfer?

    Uncertainty and limitations

    PGT is a medical procedure with technical limitations. It cannot guarantee that an embryo will implant, that a pregnancy will continue, or that a child will be born healthy. It also cannot guarantee that you will have embryos of a particular sex available for transfer. The number of embryos available depends on many factors, including your age, ovarian response, and sperm quality.

    In addition, legal and clinic policies can change. A clinic that offers family balancing today may change its policy later. Always confirm current rules before making travel or financial commitments.

    Next steps

    If you are researching PGT for family balancing in Thailand, start by clarifying your own priorities and questions. Then contact clinics directly to ask about their policies and requirements. You may also want to consult a legal professional who understands Thai assisted reproduction law. For more general information about PGT in Thailand, see our PGT in Thailand page. You can also browse our FAQ and guides for related topics. When you are ready to discuss your situation, you can contact us for guidance on next steps.

    Frequently asked questions

    Is PGT for family balancing legal in Thailand?

    Thailand regulates assisted reproduction, but the specific legal status of using PGT for family balancing depends on how the law is interpreted and applied. Clinic policies may also be stricter than the law. Because rules can change, you should confirm the current position directly with the clinic you are considering and, if needed, with a qualified Thai legal professional or the relevant health authority. This article cannot provide a definitive legal conclusion.

    What is the difference between medical PGT and family balancing?

    Medical PGT is used to test embryos for chromosomal abnormalities or specific inherited conditions, often to reduce the risk of serious genetic disease or to improve IVF outcomes. Family balancing is when PGT is used specifically to choose the sex of an embryo for non-medical reasons. Some countries allow medical PGT but restrict family balancing. Clinics may have different policies for each.

    What should I ask a clinic in Thailand about PGT for family balancing?

    Ask whether the clinic offers PGT for family balancing and under what conditions. Confirm the current Thai legal position as the clinic understands it. Ask about eligibility criteria, required documents, mandatory counseling, costs, treatment timelines, and what happens if no suitable embryos are available. Get answers in writing so you have a record.

    Can PGT guarantee a baby of a specific sex?

    No. PGT can provide information about an embryo's sex chromosomes, but it cannot guarantee that you will have embryos of a particular sex available for transfer, that an embryo will implant, that a pregnancy will continue, or that a child will be born. Many factors affect the number and quality of embryos, and no clinic can guarantee a specific outcome.

    Do I need to be married to have PGT for family balancing in Thailand?

    Document requirements, including whether marriage certificates are required, are clinic-specific and may also be affected by Thai law. You should ask the clinic directly what documents you need to provide as an international patient. Requirements can change, so confirm before you travel.

  • PGT Counseling in Thailand: A Preparation Guide for International Patients

    PGT counseling in Thailand is a structured conversation with a qualified genetics professional or fertility specialist. It helps you understand what preimplantation genetic testing (PGT) can and cannot tell you, how it fits into your IVF cycle, and what decisions you may face. For international patients, this session is also a chance to clarify logistics, costs, and follow-up. This guide outlines what to expect and how to prepare, so you can make informed choices with your clinic.

    At a glance

    • PGT counseling is an educational and decision-support session, not a test or treatment.
    • It typically covers the purpose of PGT, possible results, limitations, and alternatives.
    • For international patients, it also addresses coordination, timelines, and practical arrangements.
    • You should leave with clear next steps and a written summary or plan.
    • Costs, legal requirements, and specific clinic protocols vary; confirm these directly with your provider.

    What is PGT counseling?

    PGT counseling is a dedicated consultation before you decide whether to include PGT in your IVF treatment. It is usually led by a genetic counselor, a reproductive endocrinologist, or another qualified professional. The goal is to help you understand the medical, ethical, and practical aspects of PGT so you can give informed consent or choose an alternative.

    During the session, you can expect to discuss:

    • The different types of PGT (such as PGT-A, PGT-M, PGT-SR) and what each looks for.
    • How PGT is performed in the laboratory and what the results may mean.
    • The limitations of PGT, including the possibility of inconclusive results or the need for further testing.
    • Alternatives to PGT, such as prenatal testing or no testing.
    • Potential emotional, financial, and family implications.

    For international patients, the counselor should also address how communication will work across time zones, what documents you may need, and how results will be shared.

    Why counseling matters for international patients

    Undergoing IVF with PGT abroad involves additional layers of planning. Counseling helps you:

    • Understand the clinic’s specific PGT protocols and laboratory capabilities.
    • Clarify what is included in the quoted price and what may cost extra.
    • Learn how long you may need to stay in Thailand and whether monitoring can be done locally.
    • Discuss legal and regulatory considerations that may apply to you as a foreign patient.
    • Plan for communication with your home clinic or doctor.

    Because regulations and clinic policies can change, always confirm current requirements with your chosen clinic and, if needed, a legal advisor familiar with Thai assisted reproduction law.

    Preparing for your PGT counseling session

    Good preparation helps you get the most from your consultation. Consider these steps:

    1. Gather your medical records. Collect relevant history, previous IVF cycles, genetic test results, and any family history of genetic conditions. Ask your home clinic for a summary in English.
    2. List your questions. Write down what you want to know about PGT, success rates, risks, and logistics. Prioritize your top concerns.
    3. Clarify your goals. Think about what you hope to achieve with PGT and what you would do if results are uncertain or not what you expected.
    4. Check practical details. Confirm the appointment time, platform (in-person or video), language support, and who will be present.
    5. Prepare for emotional aspects. Consider bringing a partner or support person, and allow time to process the information.

    Questions to ask during PGT counseling

    Use this list as a starting point. Add your own questions based on your situation.

    Category Questions to ask
    Medical suitability Is PGT appropriate for my situation? What are the benefits and limitations? What alternatives exist?
    Test details Which type of PGT do you recommend and why? What does the test look for? What is the chance of an inconclusive result?
    Laboratory Is PGT performed in-house or sent to another lab? What is the lab’s experience? How are samples tracked?
    Results & follow-up How long do results take? How will they be explained? What support is available if results are unexpected?
    Costs What is included in the quoted price? Are there additional fees for counseling, testing, or storage? How are payments handled?
    Logistics How long do I need to stay in Thailand? Can monitoring be done at home? What if I need to change plans?
    Legal & ethical Are there any legal restrictions for international patients? How are embryos stored and disposed of? What consent forms are required?

    What to expect after counseling

    After your session, you should receive a summary of the discussion and a clear plan. This may include:

    • Recommended next steps, such as additional genetic testing or a consultation with a specialist.
    • A timeline for your IVF cycle and PGT.
    • An estimate of costs and payment schedule.
    • Contact information for follow-up questions.

    Take time to review the information. You are not obligated to proceed immediately. It is reasonable to ask for a second counseling session or to seek a second opinion.

    Checklist for international patients

    Use this checklist to stay organized:

    • Collect and translate medical records.
    • Confirm appointment details and language support.
    • Prepare a list of questions.
    • Ask about costs and what is included.
    • Clarify visa and travel requirements with relevant authorities.
    • Arrange accommodation and travel insurance.
    • Plan for communication with your home clinic.
    • Consider emotional support and decide who will accompany you.
    • Review consent forms carefully and ask for clarification.
    • Keep copies of all documents.

    Next steps

    If you are considering PGT in Thailand, start by contacting clinics to ask about their counseling process. You can also review our PGT in Thailand overview and patient resources for more guidance. For personalized questions, contact us or check our FAQ.

    Frequently asked questions

    Is PGT counseling mandatory before PGT in Thailand?

    Most clinics require some form of counseling or informed consent discussion before PGT. The exact requirement varies by clinic and your individual situation. Ask your chosen clinic what is required.

    Can I do PGT counseling remotely from my home country?

    Many clinics offer video consultations for international patients. However, some parts of the process may require in-person visits. Confirm with your clinic whether remote counseling is available and what it covers.

    What should I do if I feel pressured to decide quickly?

    You have the right to take time to consider your options. It is reasonable to ask for additional information, a second consultation, or a second opinion. No ethical clinic should pressure you into an immediate decision.

    Does PGT counseling include information about costs?

    Counseling often covers the financial aspects of PGT, but the level of detail varies. You should specifically ask for a written cost estimate and clarification on what is included or excluded.

    What if I don't speak Thai?

    Many clinics that serve international patients offer counseling in English or with an interpreter. Confirm language support when you schedule your appointment.

  • PGT Travel Planning in Thailand: A Practical Guide for International Patients

    Planning a PGT trip to Thailand involves more than booking a flight. You are coordinating a clinical schedule, travel documents, accommodation, communication across time zones and a follow-up plan for when you return home. This guide walks through the practical categories international patients typically need to organise, and highlights the questions worth confirming directly with your treating clinic and the relevant authorities before you commit to dates or payments. It does not provide medical advice or predict outcomes.

    At a glance

    • Start with a remote consultation before you book anything non-refundable.
    • Ask the clinic for a written provisional schedule covering monitoring, the PGT procedure and any waiting periods.
    • Treat visa, entry and document requirements as items to verify with official sources, not assumptions.
    • Build travel flexibility into flights and accommodation because clinical timelines can shift.
    • Agree in advance how results and follow-up will be communicated after you return home.

    Why travel planning matters for PGT

    PGT, or preimplantation genetic testing, is a laboratory step within an IVF cycle. Because it sits inside a broader treatment sequence, the timing of your travel is usually tied to your cycle rather than to a fixed appointment you can simply move. That is why travel planning for a PGT trip to Thailand tends to be more about sequencing and contingency than about choosing a destination.

    Two practical consequences follow. First, you may need to be in Thailand for a defined window rather than a single day. Second, plans can change if your clinical schedule shifts. Building in flexibility is often more valuable than optimising for the shortest possible trip.

    Step-by-step: planning sequence

    1. Clarify your clinical pathway first. Ask the clinic what your cycle is expected to involve and where PGT fits within it.
    2. Request a provisional written schedule. Ask for the expected sequence, approximate windows and which parts depend on monitoring results.
    3. Confirm document and entry requirements. Check official government sources and the clinic for what you personally need.
    4. Book flexible travel. Prefer changeable flights and accommodation with clear cancellation terms.
    5. Arrange accommodation near the clinic. Prioritise travel time to appointments over other considerations.
    6. Set up communication. Agree on the channel, language and time zone for updates.
    7. Plan your return and follow-up. Confirm how results and next steps will be handled once you are home.

    Documents and preparation before you travel

    Document requirements vary by nationality, personal situation and the clinic’s own administrative processes. Rather than relying on general advice, treat this as a checklist to confirm directly.

    • Which identity and civil-status documents does the clinic require, and in what form?
    • Do any documents need translation, certification or legalisation, and who can arrange that?
    • What consent or counselling steps are required before treatment, and can any be completed remotely?
    • Which records from your home clinic should be sent ahead, and how?
    • What entry, visa or stay requirements apply to you, according to official sources?

    Keep digital and physical copies of everything, and store them somewhere you can access from abroad.

    Remote consultations and coordination

    A remote consultation is usually the point where travel planning becomes concrete. It is also your opportunity to test how communication will work across time zones and languages.

    Useful questions to ask a clinic:

    • Who is my main point of contact, and how quickly do they typically respond?
    • Which language will consultations and written instructions be in?
    • How are appointments scheduled across time zones?
    • What is the expected sequence of appointments once I arrive?
    • Which parts of the schedule are fixed and which depend on monitoring?
    • How will I be told about changes to the plan?
    • What costs should I expect, and what is the payment schedule?
    • What happens if my cycle needs to be adjusted or paused?

    Ask for key information in writing where possible. Written summaries reduce the risk of misunderstanding, particularly when instructions are given in a second language.

    How long might you need to stay?

    Stay duration for a PGT trip to Thailand depends on your individual protocol, how your cycle progresses and how the clinic sequences monitoring, the procedure and any waiting periods. Because these factors vary, no general figure can be applied to every patient.

    Instead of estimating from general sources, ask your clinic to outline the range of scenarios that could apply to you:

    • What is the shortest realistic stay, and what would need to happen for that to apply?
    • What is the longest realistic stay if the schedule extends?
    • Are there waiting periods between stages, and how long are they typically?
    • Could any part of the process be completed remotely or locally?
    • What would cause a delay, and how is that usually handled?

    Use the answers to decide how much buffer to build into your trip and how much leave to request.

    Travel flexibility and contingency planning

    Clinical timelines can shift for reasons that are routine rather than alarming. Planning for that possibility is part of responsible travel preparation.

    • Choose flights that can be changed, and check the change conditions before booking.
    • Consider accommodation that allows extensions or has flexible cancellation terms.
    • Keep a contingency budget for additional nights, local transport and meals.
    • Check whether your travel insurance covers trip disruption and what it excludes.
    • Have a plan for a companion or support person, including their own leave and costs.
    • Keep essential medication and documents in your hand luggage.

    Accommodation and daily logistics

    For a PGT trip to Thailand, proximity to the clinic often matters more than other features. Appointment times can be early, and repeated visits make short, predictable journeys valuable.

    Practical considerations:

    • Travel time to the clinic at the times you are likely to attend.
    • Accessibility and quiet, given that rest may matter during treatment.
    • Kitchen or food options if you prefer familiar meals.
    • Laundry, longer-stay discounts and workspace if you are combining treatment with remote work.
    • Clear cancellation and extension terms.

    If you are travelling with a partner or companion, confirm that the accommodation suits two people for a potentially extended stay.

    Communication, privacy and records

    Privacy expectations and data-handling practices differ between countries and providers. It is reasonable to ask how your information will be stored, who can access it and how it will be shared with your home clinic.

    • How are my records stored and for how long?
    • Who within the clinic can see my information?
    • How will information be shared with my home clinic, and do I need to consent?
    • Which messaging or portal system is used, and is it secure?
    • Can I request copies of my records, and in what format?

    If you prefer a particular communication channel, say so early. Clear expectations reduce stress later.

    Returning home and follow-up

    Follow-up planning is often overlooked until the end of a trip. Discuss it before you travel, not after.

    • What information will I receive before I leave Thailand?
    • How and when will results be communicated?
    • Who do I contact with questions after I return home?
    • What follow-up might be recommended locally, and can the clinic liaise with my home provider?
    • What records should I take with me?

    If you plan to involve a doctor at home, ask whether the clinic can share a summary in a format your local provider can use.

    Planning checklist

    Area What to confirm
    Clinical schedule Provisional written timeline and which parts may change
    Documents Clinic requirements and official entry requirements for your situation
    Travel Changeable flights and realistic buffers
    Accommodation Proximity, flexibility and suitability for an extended stay
    Communication Contact person, language, channel and response expectations
    Privacy Record storage, access and sharing with your home clinic
    Follow-up How results and next steps will be handled after you return

    Next steps

    Begin with a remote consultation and a written provisional schedule. Confirm document and entry requirements through official sources. Then book flexible travel and accommodation, and agree your follow-up plan before departure. For general orientation, see our pages for international patients, the treatment process and patient resources.

    Frequently asked questions

    How long do I need to stay in Thailand for PGT?

    Stay duration depends on your individual protocol, how your cycle progresses and how the clinic sequences monitoring, the procedure and any waiting periods. Ask your clinic for the shortest and longest realistic scenarios that could apply to you, and build travel flexibility around those ranges.

    Can I do part of the process remotely?

    Some preparation, consent steps and consultations may be possible remotely, but this varies by clinic and by your situation. Ask which steps must be completed in person and which can be handled before you travel.

    What documents should I prepare?

    Requirements vary by nationality, personal circumstances and clinic policy. Ask the clinic which identity, civil-status and consent documents it needs, whether translation or legalisation is required, and check official government sources for entry and visa requirements.

    What if my schedule changes while I am in Thailand?

    Clinical timelines can shift. Choose changeable flights and accommodation with flexible terms, keep a contingency budget, and confirm with the clinic how schedule changes are communicated and handled.

    How will I receive results after I return home?

    Discuss this before you travel. Ask how and when results will be communicated, who to contact with questions, and whether the clinic can share a summary with a doctor in your home country.

  • PGT for Male Factor Infertility in Thailand: When It Helps and What It Cannot Do

    PGT, or preimplantation genetic testing, is a laboratory step performed on embryos created through IVF. It is not a treatment for low sperm count, poor motility or abnormal sperm shape, and it does not repair sperm or improve fertilisation. For male factor infertility, PGT becomes relevant mainly when there is a known or suspected genetic cause, such as an inherited chromosome rearrangement or a single-gene condition that can be passed to a child. In many cases, male factor infertility is managed through IVF or ICSI without PGT. Whether PGT adds value depends on your diagnosis, your history and what a genetic test can actually detect.

    At a glance

    • PGT tests embryos, not sperm. It cannot treat male factor infertility itself.
    • PGT-A counts chromosomes; PGT-M looks for a specific known gene change; PGT-SR looks for a known chromosome rearrangement.
    • Male factor infertility alone is not usually an indication for PGT unless a genetic cause is identified or strongly suspected.
    • Severe male factor may be linked to chromosome conditions such as Klinefelter syndrome or Y chromosome microdeletions, which can affect the chance of passing a condition to a child.
    • PGT is not a guarantee of pregnancy, live birth or a healthy child.
    • Availability, eligibility and legal rules vary. Confirm details directly with the treating clinic and relevant authorities in Thailand.

    What PGT is and what it is not

    PGT is performed on a small sample of cells taken from an embryo during IVF, usually at the blastocyst stage. The sample is tested in a genetics laboratory, and the result is used to help decide which embryos may be suitable for transfer. PGT does not change the embryo, and it does not treat the cause of male factor infertility.

    It is important to separate three ideas:

    • Fertilisation is the joining of sperm and egg. Male factor infertility affects this step, which is why ICSI is often used.
    • Embryo development is how the fertilised egg grows in the laboratory. PGT does not improve development.
    • Genetic testing looks for specific chromosome or gene findings in the embryo. This is where PGT sits.

    PGT is not a screening test for all possible health conditions, and it cannot predict intelligence, appearance or future health in general.

    Why male factor infertility may raise genetic questions

    Male factor infertility is a broad term. It can include low sperm concentration, low motility, abnormal morphology, or a combination. In some men, the cause is genetic or chromosomal. Examples that may be relevant to family planning include:

    • Klinefelter syndrome and other sex chromosome variations, which can affect sperm production.
    • Y chromosome microdeletions, which can affect sperm production and may be passed to sons.
    • Balanced chromosome rearrangements in the man, which may not affect his health but can increase the chance of miscarriage or a child with a chromosome condition.
    • Single-gene conditions that run in the family, such as cystic fibrosis or spinal muscular atrophy, where the man carries a known change.

    These are examples, not a complete list. A genetic evaluation, often including a blood test and a review of family history, is needed to know whether any of these apply to you. PGT is only useful when there is a specific finding to test for.

    PGT-A, PGT-M and PGT-SR: what each one does

    The three main types of PGT answer different questions. They are not interchangeable.

    Type What it looks at Typical male-factor link Main limitation
    PGT-A Number of chromosomes in an embryo (for example, extra or missing chromosomes) Not specific to male factor. May be discussed with advanced maternal age, recurrent miscarriage or repeated IVF failure. Does not detect single-gene conditions or balanced rearrangements. Some embryos with normal test results still do not implant.
    PGT-M A specific single-gene condition that is known to run in the family Relevant when the man carries a known gene change that could be passed on. Requires a known gene change and a custom test. It does not screen for other conditions.
    PGT-SR A known chromosome rearrangement, such as a balanced translocation Relevant when the man has a confirmed balanced rearrangement linked to miscarriage or chromosome conditions in children. Requires a confirmed rearrangement and a custom test. It does not detect unrelated conditions.

    In practice, a clinic may combine PGT-A with PGT-M or PGT-SR, depending on the case. The choice should follow from a genetic diagnosis, not from male factor infertility alone.

    When PGT may add value in male factor infertility

    PGT may be worth discussing when at least one of the following applies:

    • A man has a confirmed chromosome rearrangement, and the couple wants to reduce the chance of passing an unbalanced chromosome condition to a child.
    • A man carries a known single-gene change, and the couple wants to avoid passing that condition to a child.
    • A couple has a history of recurrent miscarriage or repeated IVF failure, and a genetic cause is suspected or confirmed.
    • A couple is already having IVF with ICSI for male factor infertility, and a separate genetic indication exists.

    In these situations, PGT can provide information that helps prioritise embryos for transfer. It does not remove all risk, and it does not guarantee a healthy child.

    When PGT is unlikely to help

    PGT is unlikely to change management when:

    • The only issue is low sperm count, poor motility or abnormal shape, with no known genetic cause.
    • There is no specific condition to test for.
    • The couple would not change their decision about which embryo to transfer based on the result.
    • The clinic does not offer the specific test, or the laboratory cannot validate it for the condition in question.

    In these cases, the focus is usually on IVF or ICSI, sperm retrieval if needed, and standard embryo selection by a embryologist. PGT adds cost and complexity without a clear benefit.

    What PGT cannot do

    • It cannot fix sperm problems or improve fertilisation.
    • It cannot guarantee pregnancy, live birth or a healthy child.
    • It cannot detect every genetic condition.
    • It cannot predict how an embryo will develop after transfer.
    • It cannot replace a genetic consultation or a full fertility assessment.

    Some embryos tested as normal may still fail to implant, and some pregnancies may still be affected by a condition that was not tested for. These are limits of the technology, not failures of the clinic.

    Alternatives and complementary steps

    Depending on your situation, options other than PGT may include:

    • Genetic counselling to understand inheritance patterns and reproductive options.
    • Donor sperm, which may be considered when the man has a condition that could be passed on and PGT is not suitable or available.
    • Prenatal testing during pregnancy, such as chorionic villus sampling or amniocentesis, which can detect certain conditions after natural or assisted conception.
    • IVF or ICSI without PGT, which may be appropriate when there is no genetic indication.

    These are not mutually exclusive. A genetic counsellor or fertility specialist can help you weigh them.

    What to ask a clinic in Thailand

    If you are considering PGT in Thailand, ask direct questions and ask for written answers where possible:

    • Does my case have a specific genetic indication for PGT, and which type?
    • What genetic testing do you recommend for me before we decide?
    • Does your laboratory perform the specific test I need, or does it send samples elsewhere?
    • What are the limitations of the test in my case?
    • What are the costs, including genetic counselling, embryo biopsy, laboratory testing and any repeat testing?
    • What happens to embryos that are not transferred?
    • What are the legal and regulatory requirements for international patients in Thailand?
    • What support is available in my language?

    Costs, documents, timelines and legal rules change. Confirm them directly with the clinic and, where relevant, with the appropriate authority. Do not rely on general guides for time-sensitive details.

    Planning steps for international patients

    1. Clarify the male diagnosis. Ask for a full semen analysis, a review of medical and family history, and any recommended genetic tests.
    2. Meet a genetic counsellor or specialist. Understand whether there is a condition that PGT can detect and what the inheritance pattern is.
    3. Confirm the indication for PGT. If there is no specific genetic finding, ask why PGT is being recommended.
    4. Check laboratory capability. Not every clinic offers every PGT type. Ask how the test is validated and how long results take.
    5. Compare options. Discuss IVF or ICSI with and without PGT, donor sperm, and prenatal testing.
    6. Plan travel and logistics. Ask about the number of visits, monitoring, and how results are communicated.
    7. Confirm costs and legal requirements. Request a written breakdown and check current rules for international patients.

    Frequently asked questions

    Does male factor infertility always mean I need PGT?

    No. Male factor infertility alone is not usually an indication for PGT. PGT is considered when there is a specific genetic finding, such as a known chromosome rearrangement or a single-gene condition, that can be tested in embryos. If no such finding exists, IVF or ICSI without PGT may be more appropriate. A genetic evaluation can help clarify whether PGT is relevant for you.

    Can PGT improve sperm quality or fix male infertility?

    No. PGT tests embryos, not sperm. It does not improve sperm count, motility or shape, and it does not treat the cause of male factor infertility. Sperm problems are usually managed through IVF with ICSI, sometimes with sperm retrieval. PGT is a separate step that looks for specific genetic findings in embryos.

    What is the difference between PGT-A, PGT-M and PGT-SR?

    PGT-A looks at the number of chromosomes in an embryo and is not specific to male factor infertility. PGT-M looks for a known single-gene condition that runs in the family. PGT-SR looks for a known chromosome rearrangement, such as a balanced translocation. Each test requires a different type of genetic finding, and they are not interchangeable.

    Is PGT available in Thailand for international patients?

    Many fertility clinics in Thailand offer IVF and some form of genetic testing, but availability varies by clinic and by the specific test. Legal and regulatory requirements for international patients can also change. You should confirm directly with the clinic whether they offer the PGT type you need, what the current requirements are, and what costs and timelines apply.

    Does a normal PGT result guarantee a healthy baby?

    No. PGT can reduce the chance of transferring an embryo with a specific chromosome or gene finding, but it cannot guarantee pregnancy, live birth or a healthy child. Some conditions are not tested for, and some embryos with normal results still do not implant. Your clinic can explain the limits of the test in your specific case.

  • PGT for Recurrent Miscarriage in Thailand: An Indication-Based Guide for International Patients

    PGT, or preimplantation genetic testing, is a laboratory add-on to IVF that examines embryos for certain chromosomal or genetic features before transfer. For people with recurrent miscarriage, it is sometimes discussed as one possible way to reduce the chance of transferring an embryo with a chromosomal abnormality that could lead to another loss. It is not a guarantee, not a diagnosis of why losses happened, and not automatically recommended for everyone. Whether it is appropriate depends on your history, prior testing and what a fertility specialist concludes after review.

    At a glance

    • Recurrent miscarriage is a distinct indication for discussing PGT, separate from maternal age or repeated IVF failure.
    • PGT-A counts chromosomes; PGT-M looks for a known inherited condition; PGT-SR looks at known structural chromosome rearrangements.
    • PGT requires IVF, because embryos must be created and biopsied in a laboratory.
    • A normal PGT result lowers but does not eliminate the chance of miscarriage.
    • Guidelines do not treat PGT as a routine first-line answer for every case of recurrent loss.
    • Ask the clinic how it defines recurrent miscarriage, what testing it recommends first, and how it would use PGT in your situation.

    Why recurrent miscarriage is its own conversation

    Recurrent pregnancy loss is usually defined as a certain number of consecutive miscarriages, though definitions vary between organizations and clinics. The causes are often mixed: chromosomal factors in the pregnancy, uterine anatomy, hormonal or metabolic conditions, blood-clotting disorders, infection, and sometimes no identifiable cause. Because the reasons differ from person to person, the evaluation matters as much as any single treatment.

    PGT enters this conversation only after the broader picture is considered. If a couple has had losses and prior testing has identified a specific chromosomal issue, PGT may be more directly relevant. If no cause has been found, the role of PGT is less clear and should be discussed carefully rather than assumed.

    What PGT-A, PGT-M and PGT-SR actually test

    PGT is an umbrella term. The three main types answer different questions.

    Type What it looks at Typical context
    PGT-A Number of chromosomes in an embryo (aneuploidy screening) Discussed when chromosomal abnormality in the pregnancy is a concern, including some recurrent loss situations
    PGT-M A specific gene variant known to run in the family When one or both parents carry a known inherited condition
    PGT-SR Structural chromosome rearrangements such as translocations When a parent has a known balanced rearrangement linked to losses

    PGT-A is the type most often raised in recurrent miscarriage discussions, because many early losses are associated with chromosomal abnormalities in the embryo. PGT-M and PGT-SR are more targeted and depend on prior genetic findings in the parents or family.

    How PGT fits into an IVF cycle

    1. Consultation and review. The clinic reviews your loss history, prior tests and any genetic results.
    2. Ovarian stimulation and egg retrieval. Medication is used to mature multiple eggs, which are collected in a minor procedure.
    3. Fertilization and embryo development. Eggs and sperm are combined in the laboratory, and embryos are monitored as they grow.
    4. Biopsy. A few cells are removed from each embryo at a suitable stage.
    5. Genetic analysis. The biopsy sample is tested for the specific question being asked.
    6. Results and transfer planning. The clinic discusses which embryos are available and how results may inform transfer.

    Each step has its own uncertainties. Not every cycle produces embryos suitable for biopsy or transfer, and testing itself can sometimes yield an unclear result.

    What a PGT result can and cannot tell you

    A PGT result is information about the cells that were sampled, not a complete picture of the embryo or a prediction of the future. A result reported as normal for the tested feature reduces the chance of a loss related to that feature, but it does not rule out miscarriage from other causes. A result reported as abnormal usually means that embryo would not be selected for transfer, though clinics handle specific findings differently.

    Some results are inconclusive. In those cases, the clinic may discuss whether re-testing is possible, whether the embryo can still be considered, or whether the result should be set aside. These decisions are clinical and should be made with the treating team.

    Evidence limits and why guidelines are cautious

    Professional guidance generally does not present PGT as a routine, first-line solution for all recurrent miscarriage. The evidence is strongest in specific situations, such as when a known parental chromosomal rearrangement is present, and less clear when losses have no identified cause. Even where PGT is used, it does not replace a full evaluation for other contributing factors.

    This is why an indication-based approach matters. The question is not simply whether PGT exists in Thailand, but whether it addresses the likely cause in your case. A clinic should be able to explain the reasoning, the alternatives, and what would change if you chose not to test.

    Alternatives and complementary steps

    Depending on your history, a clinic may discuss other evaluations or approaches alongside or instead of PGT. These can include:

    • Testing of pregnancy tissue from a previous loss, where available
    • Parental chromosome analysis (karyotyping)
    • Assessment of uterine structure
    • Screening for hormonal, metabolic or clotting conditions
    • Expectant management or further spontaneous conception with monitoring
    • Other IVF-related options, such as transferring without testing

    No single option is right for everyone. The goal is to match the approach to the likely cause and to your priorities.

    Questions to ask a clinic in Thailand

    • How do you define recurrent miscarriage, and does my history meet that definition?
    • What evaluations do you recommend before discussing PGT?
    • Which type of PGT are you considering for me, and why?
    • What proportion of embryos typically reach biopsy and transfer in your laboratory?
    • How do you handle inconclusive or unusual results?
    • What are the alternatives if I decide not to use PGT?
    • What costs are involved, and which are not included in a quoted figure?
    • What documents or preparations should international patients plan for?

    Practical planning for international patients

    Travel, visas, length of stay, medical records and payment arrangements vary by clinic and by individual situation. Because these details are time-sensitive and personal, confirm them directly with the clinic and, where relevant, with official Thai authorities. Ask for a written summary of the proposed plan, the tests involved, and the expected timeline so you can compare options clearly.

    It also helps to request your prior medical records in advance, including any genetic test results, and to ask whether translation is needed. Planning around work, childcare and travel should account for the possibility that a cycle may not proceed exactly as hoped.

    Next steps

    1. Gather your loss history and any prior test results.
    2. Ask a fertility specialist whether PGT is indicated in your case, and why.
    3. Clarify which type of PGT is being proposed and what it can and cannot show.
    4. Discuss alternatives and the option of not testing.
    5. Confirm practical details, costs and timelines in writing before committing.

    Frequently asked questions

    Does PGT prevent miscarriage?

    No. PGT can reduce the chance of transferring an embryo with a specific chromosomal or genetic feature being tested, but it does not prevent miscarriage from other causes. Miscarriage can still occur for reasons PGT does not detect.

    Is PGT always recommended after recurrent miscarriage?

    No. Professional guidance generally does not treat PGT as a routine first-line option for every case of recurrent loss. Whether it is appropriate depends on your history, prior testing and the judgment of your treating clinician.

    What is the difference between PGT-A, PGT-M and PGT-SR?

    PGT-A looks at the number of chromosomes in an embryo. PGT-M looks for a specific inherited gene variant known in the family. PGT-SR looks at known structural chromosome rearrangements. The right type, if any, depends on what has been found in prior testing.

    Can I have PGT without IVF?

    No. PGT requires embryos created through IVF, because the test is performed on cells taken from an embryo in the laboratory. If you conceive without IVF, PGT is not applicable to that pregnancy.

    What should I ask a clinic in Thailand about PGT?

    Ask how they define recurrent miscarriage, what evaluations they recommend first, which type of PGT they propose and why, how they handle unclear results, what alternatives exist, and what costs and practical arrangements apply to international patients.

  • PGT vs No PGT in Thailand: How to Decide About Embryo Testing

    PGT (preimplantation genetic testing) is an optional laboratory step added to IVF. It examines a small sample of cells from an embryo before transfer. Choosing PGT versus no PGT in Thailand is not a simple right-or-wrong decision. It depends on your medical history, the reason for IVF, what information you want, and how you weigh possible benefits against added cost, waiting time, and uncertainty. PGT can reduce the chance of transferring an embryo with a specific chromosomal or genetic finding, but it cannot guarantee a healthy pregnancy, a live birth, or a healthy child. Some patients choose testing; others reasonably choose untested transfer.

    At a glance

    • PGT-A screens embryos for extra or missing chromosomes (aneuploidy).
    • PGT-M looks for a known single-gene condition that runs in a family.
    • PGT-SR looks at chromosome structure, such as translocations.
    • PGT is optional. It is not required for every IVF cycle and is not a guarantee of success.
    • Testing adds laboratory work, cost, and usually a wait for results before transfer.
    • No test can remove all uncertainty. Some embryos with normal results still do not implant, and some untested embryos do.

    What PGT can and cannot tell you

    PGT is a screening or diagnostic tool used during IVF. It does not treat infertility, improve embryo quality, or make an embryo more likely to implant. It provides information that you and your clinician can use when deciding which embryo or embryos to transfer.

    What PGT may offer:

    • Information about chromosome number (PGT-A) or a known gene change (PGT-M) or chromosome structure (PGT-SR).
    • A way to consider avoiding transfer of embryos with certain findings, when alternatives exist.
    • Possibly fewer transfers or a lower chance of miscarriage in some situations, depending on the reason for testing and the clinic’s protocols.

    What PGT cannot do:

    • Guarantee pregnancy, live birth, or a child without a health condition.
    • Detect every possible genetic or chromosomal problem.
    • Replace prenatal testing or newborn screening.
    • Tell you whether an embryo will definitely implant.
    • Make an untested embryo unsafe or a tested embryo safe in absolute terms.

    Because PGT is a laboratory test, results can be affected by sample quality, the technology used, and the specific condition being tested. Your clinic should explain the limitations for your situation.

    PGT-A, PGT-M, and PGT-SR: different questions, different decisions

    These are not interchangeable tests. Each answers a different question, and each has its own reasons for being considered.

    Test What it looks at Common reason it is discussed Key limitation
    PGT-A Number of chromosomes in the embryo sample Advanced maternal age, recurrent miscarriage, repeated implantation failure, or previous pregnancy with a chromosome condition Does not test for single-gene disorders; may not detect all chromosome changes; some results are uncertain
    PGT-M A specific gene change known to run in the family Family history of a single-gene condition, such as cystic fibrosis or spinal muscular atrophy Requires a known gene change and often a custom test setup; does not screen for unrelated conditions
    PGT-SR Chromosome structure, such as a translocation Known chromosome rearrangement in a parent, or repeated pregnancy loss linked to a structural issue Does not detect all chromosome problems; interpretation depends on the specific rearrangement

    If you are considering PGT, ask which test is being proposed and why. The answer should connect to your history, not to a general rule.

    PGT versus no PGT: a decision-framing comparison

    This comparison is about the choice to test or not to test. It is not a ranking of clinics or a promise of outcomes. Use it to organize your own questions.

    Decision factor Choosing PGT Choosing no PGT
    Information before transfer You receive laboratory information about the embryo sample before deciding which embryo to transfer. You transfer based on embryo appearance and development, without that genetic information.
    Time to transfer Usually requires waiting for laboratory results, which can extend the cycle or lead to a frozen transfer. Transfer may be scheduled sooner, depending on your protocol and clinic schedule.
    Cost Adds laboratory and possibly storage or biopsy-related fees. Ask for a written breakdown. Avoids PGT-specific laboratory fees, though IVF costs remain.
    Embryo handling Involves embryo biopsy and often freezing while results are pending. Avoids biopsy and the associated laboratory steps.
    Uncertainty May reduce some uncertainty about specific chromosome or gene findings, but does not remove all uncertainty. Leaves chromosome or gene status unknown before transfer; some uncertainty remains either way.
    Emotional load Waiting for results and interpreting them can be stressful; results may be inconclusive. Avoids result-waiting, but may leave questions unanswered.
    Best fit Often discussed when there is a specific medical reason, such as a known familial condition or a history that raises concern. Often reasonable when there is no specific indication, when few embryos are available, or when a patient prefers to avoid testing.

    Neither column is automatically better. The right choice for you depends on your medical situation, your values, and what your clinic can support.

    When PGT is more likely to be discussed

    Clinics may raise PGT when certain factors are present. These are conversation starters, not eligibility rules.

    • A known single-gene condition in the family, where PGT-M could be considered.
    • A known chromosome rearrangement, where PGT-SR could be considered.
    • Recurrent pregnancy loss or repeated implantation failure, where PGT-A may be discussed.
    • Advanced maternal age, where the chance of chromosome differences in embryos is higher.
    • A previous pregnancy or child with a chromosome condition.
    • Preference for more information before transfer, after counseling about limits.

    Even when these factors are present, PGT is a choice. Your clinician should explain the possible benefits and the possible downsides for your specific case.

    When no PGT may be a reasonable path

    Some patients decide against PGT. This can be a considered decision, not a failure to try hard enough.

    • There is no specific genetic or chromosomal indication.
    • Very few embryos are available, and the patient prefers to transfer without waiting or biopsy.
    • The added cost or time is a significant burden.
    • The patient prefers to avoid biopsy or freezing for personal reasons.
    • The patient understands that PGT would not remove all uncertainty and chooses not to add the step.

    If you choose no PGT, your clinic may still recommend other assessments or prenatal testing later. Ask what monitoring is appropriate for you.

    Understanding PGT results

    PGT results are usually reported in categories. Exact wording varies by laboratory and test.

    • Normal or euploid: The sample did not show the specific finding being tested for. This does not guarantee implantation or a healthy baby.
    • Abnormal or aneuploid: The sample showed a chromosome difference. Some findings are more serious than others, and some may be confined to the sample.
    • Mosaic: The sample showed a mix of cells with different chromosome patterns. The meaning can be uncertain, and counseling is important.
    • Inconclusive or no result: The test could not give a clear answer. This can happen for technical reasons.
    • Carrier or affected (PGT-M): For single-gene conditions, results describe whether the embryo is predicted to be affected, a carrier, or unaffected, depending on the condition and test.

    Ask your clinic who will explain the result, what it means for transfer decisions, and whether confirmatory testing during pregnancy is recommended.

    Alternatives and complements to PGT

    PGT is one option among several. Depending on your situation, your clinician may discuss:

    • Transferring untested embryos, with or without additional embryo assessment.
    • Prenatal screening or diagnostic testing during pregnancy, such as ultrasound, blood tests, chorionic villus sampling, or amniocentesis.
    • Carrier screening for parents before or during IVF planning.
    • Genetic counseling to understand risks and options.
    • Donor gametes or embryos, where relevant and lawful.

    These are not mutually exclusive. Some patients use PGT and later prenatal testing; others use neither and rely on standard prenatal care.

    Practical questions to ask a clinic in Thailand

    Use these questions to compare what different clinics offer and how they communicate. You can also review general guidance in our PGT in Thailand resource and guides.

    1. Which PGT test are you recommending for my situation, and why?
    2. What are the possible benefits and limitations for someone with my history?
    3. What is the full cost of PGT, including biopsy, laboratory fees, freezing, storage, and any re-testing?
    4. How long do results usually take, and how does that affect my transfer plan?
    5. What happens if the result is inconclusive or mosaic?
    6. Who will counsel me on results, and in what language?
    7. What are my options if I choose not to test?
    8. What prenatal testing do you recommend after transfer, whether or not I use PGT?
    9. What are your laboratory’s accreditation and quality-control practices?
    10. What documents, visas, or legal steps should I confirm before traveling?

    Next-step checklist

    • Clarify your main reason for considering IVF and whether a specific genetic risk is known.
    • Ask your clinician whether PGT is medically indicated, optional, or not recommended for you.
    • Request a written cost estimate that separates IVF, PGT, medication, storage, and travel.
    • Ask how PGT would change your timeline and whether a frozen transfer would be needed.
    • Consider genetic counseling if you have a family history or a known chromosome finding.
    • Decide what level of uncertainty you are comfortable with before transfer.
    • Confirm legal, visa, and documentation requirements with the clinic and relevant authorities.
    • Review our FAQ for common patient questions.

    The bottom line

    PGT versus no PGT in Thailand is a personal medical decision, not a test of commitment. PGT can provide useful information in some situations, but it is not required for everyone and does not guarantee outcomes. No PGT is also a valid path when testing is not indicated, not affordable, or not aligned with your preferences. The best next step is a detailed conversation with a qualified clinician who can review your history, explain the limits of testing, and help you weigh the trade-offs.

    Frequently asked questions

    Is PGT required for IVF in Thailand?

    No. PGT is an optional laboratory step. Whether it is recommended depends on your medical history, the reason for IVF, and your preferences. Some patients have a specific indication, such as a known familial genetic condition or a history of recurrent pregnancy loss. Others proceed without testing. Your clinic should explain whether PGT is medically indicated, optional, or not recommended for your situation.

    Does PGT improve the chance of a successful pregnancy?

    PGT does not guarantee pregnancy or a live birth, and it does not improve embryo quality. In some situations, testing may help avoid transferring an embryo with a specific chromosomal or genetic finding. However, tested embryos can still fail to implant, and untested embryos can result in healthy pregnancies. The effect on success depends on the reason for testing, the clinic's protocols, and individual factors.

    What is the difference between PGT-A, PGT-M, and PGT-SR?

    PGT-A looks at chromosome number and is often discussed in cases of advanced maternal age, recurrent miscarriage, or repeated implantation failure. PGT-M looks for a specific single-gene condition known to run in a family. PGT-SR looks at chromosome structure, such as a translocation. Each test answers a different question and has different limitations. Your clinic can explain which, if any, is relevant for you.

    Can I choose no PGT and still have a healthy pregnancy?

    Yes. Many patients transfer untested embryos and have healthy pregnancies. Choosing no PGT is a reasonable option, especially when there is no specific genetic indication, when few embryos are available, or when the added cost or waiting time is a concern. Your clinic may still recommend standard prenatal screening or diagnostic testing during pregnancy.

    What should I ask about the cost of PGT in Thailand?

    Ask for a written breakdown that separates IVF costs from PGT-specific costs, such as embryo biopsy, laboratory testing, freezing, storage, and any re-testing. Costs vary by clinic and by the type of test. Because prices change and are clinic-specific, confirm current fees directly with the clinic rather than relying on general figures.

    How long does PGT take, and will it delay my transfer?

    PGT usually requires waiting for laboratory results, which can extend the cycle or lead to a frozen embryo transfer. The exact timeline depends on the laboratory, the test, and the clinic's schedule. Ask your clinic how long results typically take and how that affects your transfer plan.

  • How to Interpret PGT Success Rates in Thailand: A Guide for International Patients

    When you search for PGT success rates in Thailand, you will find many numbers. Some clinics publish pregnancy rates, others live birth rates, and some quote figures for very specific patient groups. These numbers can be useful, but they rarely mean what they appear to mean at first glance. A success rate is not a property of a clinic alone. It depends on who is treated, which test is used, how embryos are selected, and how the outcome is defined. This guide explains how to read PGT outcome claims carefully, what questions to ask, and why a single percentage should never be your only decision tool.

    At a glance

    • PGT success rates are not standardized across clinics or countries.
    • Pregnancy rate and live birth rate are different measures.
    • PGT-A, PGT-M, and PGT-SR answer different questions and have different expected outcomes.
    • Patient age, embryo quality, and clinic laboratory practices strongly influence results.
    • No test can guarantee a healthy pregnancy or a healthy child.
    • Ask how a number was calculated before you compare it with another clinic.

    What “success rate” actually means in PGT

    In fertility care, success can be defined in several ways. A clinic might report the proportion of embryo transfers that resulted in a positive pregnancy test. Another might report clinical pregnancy, confirmed by ultrasound. Another might report live birth. These are not interchangeable. A positive pregnancy test is an early signal, not a guarantee that a pregnancy will continue. A live birth rate is a later and generally more meaningful outcome, but it is also influenced by factors that occur after the embryo transfer.

    When you see a PGT success rate, the first question is: success at what point? Without that definition, the number is difficult to interpret. A high pregnancy rate with a lower live birth rate tells a different story than a high live birth rate. Neither is automatically better or worse without context.

    Why PGT-A, PGT-M, and PGT-SR cannot share one success rate

    Preimplantation genetic testing is an umbrella term. Each type of PGT has a different purpose, and that affects what a meaningful outcome looks like.

    PGT-A

    PGT-A screens embryos for extra or missing chromosomes. It is often used to help select embryos for transfer. The outcome depends heavily on how many embryos are available and how many are chromosomally normal. A clinic’s PGT-A results will vary with the average age of its patients and the number of embryos tested per cycle.

    PGT-M

    PGT-M looks for a specific inherited condition that runs in a family. Success here is often measured by whether an unaffected embryo is identified and available for transfer. The number of unaffected embryos can vary widely depending on the condition and the parents’ genetic status. A single success rate for PGT-M across all conditions would be misleading.

    PGT-SR

    PGT-SR is used when a parent has a known structural chromosome rearrangement, such as a translocation. The proportion of normal or balanced embryos can differ greatly from one rearrangement to another. Again, a general success rate cannot capture this variation.

    Because these tests answer different questions, comparing a PGT-A rate with a PGT-M rate is not meaningful. Even within PGT-A, results depend on the patient population.

    What influences PGT outcomes in Thailand and elsewhere

    Many factors affect whether a PGT cycle leads to a live birth. Some are within a clinic’s control, and some are not.

    • Patient age: The chance of having chromosomally normal embryos generally declines with age. This affects PGT-A outcomes more than any single laboratory technique.
    • Number of embryos available: More embryos tested means more opportunities to find a suitable one for transfer. A cycle with few embryos has fewer chances.
    • Embryo quality: Morphology and development speed still matter, even with genetic testing.
    • Laboratory experience: Embryo biopsy, freezing, and genetic analysis are technical steps. Consistency and skill can influence results.
    • Reason for testing: PGT-M and PGT-SR outcomes depend on the specific genetic condition or rearrangement.
    • Definition of success: As noted above, pregnancy and live birth are different endpoints.

    Because these factors vary so much, a clinic’s published rate may reflect its patient mix more than its quality of care. A clinic that treats many younger patients with a good prognosis may report higher rates than a clinic that accepts more complex cases.

    How to read a PGT success rate claim

    When you encounter a number, try to unpack it with these questions:

    1. Is this a pregnancy rate or a live birth rate?
    2. Does it refer to PGT-A, PGT-M, PGT-SR, or a mix?
    3. Is it per embryo transfer, per cycle started, or per patient?
    4. Does it include frozen embryo transfers or only fresh transfers?
    5. What is the age range and diagnosis of the patients included?
    6. Does it include cycles that were cancelled before transfer?
    7. Is the number based on the clinic’s own data, a registry, or a general estimate?

    If a clinic cannot or will not answer these questions, treat the number with caution. A responsible clinic should be able to explain how its data are collected and what they represent.

    Why comparing clinics by a single number is risky

    International patients often look for a simple ranking. But a single success rate cannot tell you which clinic is right for you. Two clinics may report the same percentage while treating very different patients. One may specialize in older patients or complex genetic cases, while another may focus on routine IVF. The clinic with the higher number may simply have a less challenging patient population.

    In addition, reporting practices differ. Some clinics publish data regularly; others do not. Some use internal audits; others participate in external registries. Without a common standard, direct comparison is unreliable.

    This does not mean success rates are useless. They can be one part of your research. But they should be considered alongside the clinic’s experience with your specific situation, its laboratory practices, and how clearly it communicates uncertainty.

    Questions to ask a clinic about PGT outcomes

    When you contact a clinic in Thailand, consider asking these questions. You can also use them to compare written information from different providers.

    • How do you define success for PGT cycles?
    • Do you report live birth rates separately from pregnancy rates?
    • Can you share outcome data for patients with my age range and diagnosis?
    • How many PGT cycles do you perform in a typical year?
    • What is your experience with my specific genetic condition or rearrangement, if applicable?
    • What happens if no embryo is suitable for transfer after testing?
    • Are there additional costs for PGT that are not included in the initial quote?
    • How do you counsel patients about the limitations of PGT?

    These questions help you move beyond a headline number and understand the clinic’s approach. They also give you a sense of how transparent the clinic is willing to be.

    What PGT can and cannot tell you

    PGT can provide information about the chromosomal or genetic status of an embryo. It can help some patients avoid transferring embryos with certain abnormalities. However, it cannot guarantee that a transferred embryo will implant, that a pregnancy will progress, or that a child will be free of all health conditions. PGT does not test for every possible genetic disorder, and it does not replace prenatal testing.

    For some patients, PGT may not be necessary or may not improve their chances. For others, it may be a valuable tool. The decision depends on individual circumstances, and it should be made with a qualified healthcare provider who can explain the benefits and limitations.

    Planning your next steps

    If you are considering PGT in Thailand, start by clarifying your own priorities. Are you trying to reduce the risk of a specific inherited condition? Are you hoping to improve the chances of a successful pregnancy after multiple IVF attempts? Your reasons will shape which test is relevant and what outcomes matter most to you.

    Next, gather information from several clinics. Ask for written explanations of their PGT process, their outcome reporting, and their costs. Compare not just numbers but also how clearly they answer your questions. A clinic that explains uncertainty honestly may be a better partner than one that promises more than it can deliver.

    Finally, remember that success rates are only one piece of the puzzle. Your age, health, embryo quality, and the specific reason for testing all play a role. No clinic can guarantee a particular result, and any provider who does should be viewed with skepticism.

    For more context on IVF outcomes in Thailand, see our guide to IVF success rates in Thailand. To understand the testing process itself, read about PGT in Thailand. You can also explore our patient guides and frequently asked questions for more planning support.

    Frequently asked questions

    What is a good PGT success rate in Thailand?

    There is no single 'good' number because success rates depend on how they are defined and who is included. A rate that applies to one patient group may not apply to you. Instead of looking for a threshold, ask how the clinic measures success, whether it reports live birth rates, and whether it can share data for patients similar to you.

    Can PGT guarantee a healthy baby?

    No. PGT can provide information about certain chromosomal or genetic features of an embryo, but it cannot guarantee implantation, a continuing pregnancy, or a child free of all health conditions. It does not test for every possible disorder, and prenatal testing may still be recommended.

    Why do PGT success rates vary so much between clinics?

    Variation comes from differences in patient age, diagnosis, the type of PGT used, laboratory practices, and how outcomes are counted. A clinic with younger patients or simpler cases may report higher rates than one that treats more complex cases. Without standardized reporting, direct comparisons are unreliable.

    Should I choose a clinic based only on its PGT success rate?

    No. A single number cannot tell you whether a clinic is right for your situation. Consider the clinic's experience with your specific condition, its laboratory standards, how transparent it is about limitations, and how well it communicates. Success rates can be one factor among many.

    What should I ask a clinic about its PGT data?

    Ask whether the rate is for pregnancy or live birth, whether it is per transfer or per cycle, which PGT types are included, and what patient characteristics are represented. Also ask how many PGT cycles the clinic performs and what happens if no suitable embryo is found.
