  • Thailand PGT IVF for Older Patients: Age, Expectations and Questions to Ask

    If you are over 40 and considering PGT IVF in Thailand, the most useful starting point is this: PGT can give you information about the chromosomal status of embryos, but it cannot guarantee a pregnancy, a live birth or a healthy child. Age is one of the strongest factors influencing how many eggs are retrieved, how many become embryos and how many of those embryos are chromosomally normal (euploid). PGT does not change those underlying probabilities. It can help you and your clinician decide which embryos to consider transferring, and it can reduce the chance of transferring an embryo with a known chromosomal abnormality. The rest of this guide explains the tests, the limits, and the questions worth asking before you commit to a plan.

    At a glance

    • PGT-A screens embryos for extra or missing chromosomes; it is not a treatment for infertility and does not improve embryo quality.
    • PGT-M looks for a specific inherited condition known to run in a family; PGT-SR looks at structural chromosome rearrangements.
    • Euploidy rates generally decline with age, but individual results vary widely and cannot be predicted from age alone.
    • PGT is optional in most situations. It is a decision to make with a qualified clinician, not a default requirement.
    • Costs, legal rules, travel requirements and clinic-specific protocols in Thailand should be confirmed directly with the treating clinic and relevant authorities.

    What PGT actually tests

    Preimplantation genetic testing (PGT) is done on a small number of cells removed from an embryo, usually at the blastocyst stage. There are three main categories:

    • PGT-A (aneuploidy): checks for an abnormal number of chromosomes, such as an extra or missing copy. This is the type most often discussed with older patients.
    • PGT-M (monogenic): looks for a specific gene variant linked to a known inherited condition in the family.
    • PGT-SR (structural rearrangement): looks at chromosomes when a parent carries a balanced structural rearrangement, such as a translocation.

    PGT-A is a screening test, not a diagnostic test for a future child. It reports the chromosomal status of the cells sampled. Because embryos can show mosaicism — a mix of normal and abnormal cells — results are not always a simple yes or no. Some clinics report mosaic results and discuss them case by case. A result described as “abnormal” does not always mean the embryo could never produce a healthy pregnancy, and a “normal” result does not guarantee one.

    How age affects euploidy and IVF outcomes

    Age influences two separate things: how many eggs you produce, and the proportion of those eggs that are chromosomally normal. Both tend to decline with age, which is why older patients often see fewer embryos available for testing and fewer euploid embryos after testing.

    It is common to see broad patterns quoted, such as euploidy rates falling from one age band to the next. Those patterns come from large datasets and describe averages, not individuals. Two patients of the same age can have very different results. Factors such as ovarian reserve, prior IVF history, sperm quality, laboratory conditions and chance all play a role.

    Because of this, a clinic cannot promise you a specific number of euploid embryos, a specific success rate or a specific timeline. Be cautious of any source that offers a guaranteed figure for your age. A more realistic conversation is about ranges, uncertainty and what happens if testing leaves you with no embryos to transfer.

    Why PGT is not automatically the right choice

    PGT-A is sometimes presented as a way to improve success. The evidence is more nuanced. In some groups, PGT-A may help select embryos and reduce the chance of transferring an embryo with a known chromosomal abnormality. In other situations, it may reduce the number of embryos available for transfer without clearly improving the chance of a live birth. It also adds cost, laboratory steps and waiting time.

    PGT is not a treatment for low ovarian reserve, poor egg quality or recurrent implantation failure. It does not create embryos and it does not repair them. If you have very few embryos, testing may leave you with none to transfer, and some patients choose to transfer untested embryos instead. That is a legitimate option and worth discussing openly.

    Alternatives and complements to PGT

    Depending on your history, your clinician may discuss options such as:

    • Transferring untested embryos, with or without additional ultrasound or blood monitoring.
    • Using donor eggs or donor embryos, which changes the age-related equation but raises separate medical, legal and ethical questions.
    • Further fertility assessment, such as ovarian reserve testing or a review of previous cycles.
    • Genetic counseling, especially if there is a known inherited condition or a history of recurrent loss.
    • Prenatal testing after a pregnancy is established, which looks at the pregnancy rather than the embryo.

    None of these is universally better. The right path depends on your medical history, your values and what a clinic can offer you.

    What to expect during a PGT cycle in Thailand

    The general sequence is similar in most clinics, though details vary:

    1. Consultation and assessment: review of history, blood tests and ultrasound, and a discussion of whether PGT is appropriate for you.
    2. Ovarian stimulation: medication to encourage multiple eggs to mature, with monitoring visits.
    3. Egg retrieval and fertilization: eggs are collected and combined with sperm in the laboratory.
    4. Embryo culture: embryos are grown for several days, often to the blastocyst stage.
    5. Biopsy and testing: a few cells are removed and sent for genetic analysis. Some clinics send samples to a partner laboratory.
    6. Results and transfer planning: you discuss which embryos, if any, are suitable for transfer, and whether to transfer, freeze or consider another cycle.

    Timelines vary. Testing itself can take days to weeks depending on the laboratory and the test. Travel planning should account for monitoring, retrieval, possible waiting for results and a transfer that may happen in a later cycle.

    Questions to ask a clinic before you decide

    Bring these to your consultation and ask for clear, written answers where possible:

    • Which type of PGT are you recommending for my situation, and why?
    • What are the limitations of the test you use, including mosaicism and inconclusive results?
    • What happens if no embryos are suitable for transfer after testing?
    • How do you counsel patients about age-related euploidy without giving guarantees?
    • Who performs the biopsy and where is the genetic analysis done?
    • What are the total costs, including testing, storage, medication, monitoring and any follow-up?
    • What are the legal and consent requirements in Thailand for my situation, and what documents will I need?
    • What support is available if I need to travel, and how are results communicated to me?
    • Can I speak with a genetic counselor or a specialist in reproductive genetics?

    Practical next steps

    • Gather your medical records, including any previous IVF cycles, genetic tests and relevant family history.
    • Ask your current clinician whether PGT is likely to change your management, and why.
    • Request a written cost estimate and a written summary of what is and is not included.
    • Confirm visa, travel and any legal requirements with the relevant authorities and the clinic, as rules can change.
    • Consider speaking with a genetic counselor before testing, especially if there is a known inherited condition.
    • Plan for uncertainty: discuss in advance what you would do if testing leaves you with no transferable embryos.

    Frequently asked questions

    Does PGT improve the chance of pregnancy for older patients?

    PGT-A can help identify embryos with a normal number of chromosomes, which may inform which embryo to transfer. However, it does not improve the underlying quality of embryos or guarantee a pregnancy. For some patients, testing may reduce the number of embryos available. Whether PGT is likely to help depends on your individual situation, and this is best discussed with a qualified clinician.

    Can I predict my euploidy rate based on my age?

    No. Age is one factor among many. Euploidy rates tend to decline with age on average, but individual results vary widely and cannot be predicted from age alone. A clinic should discuss ranges and uncertainty rather than promise a specific number.

    Is PGT required for IVF in Thailand?

    PGT is generally optional and is not required for all patients. Recommendations depend on your medical history, the reason for treatment and clinic policy. Legal and consent requirements can change, so confirm current rules with the treating clinic and relevant authorities.

    What happens if PGT shows no normal embryos?

    This is a possible outcome, especially for older patients or those with few embryos. Clinics should discuss this scenario before testing begins. Options may include transferring an untested embryo, considering another cycle, or exploring other paths such as donor eggs, depending on your circumstances and local rules.

    Should I have genetic counseling before PGT?

    Genetic counseling can help you understand what PGT can and cannot tell you, especially if you have a known inherited condition or a history of recurrent pregnancy loss. Ask your clinic whether counseling is available and whether it is included in your care.

  • PGT-A vs PGT-M: How to Choose the Right PGT Test in Thailand

    PGT-A and PGT-M are different tests used for different reasons. PGT-A checks embryos for extra or missing chromosomes and is usually considered when age or repeated implantation failure raises concern about chromosomal number. PGT-M looks for a specific inherited condition that runs in your family. Neither test guarantees a healthy pregnancy or a live birth, and neither is right for everyone. In Thailand, the test you choose should follow a clinical assessment, genetic counselling where relevant, and a clear discussion of what the result can and cannot tell you.

    At a glance

    • PGT-A screens for chromosomal number (aneuploidy) across the embryo.
    • PGT-M targets a known single-gene or familial condition.
    • PGT-SR is a related option when a parent carries a structural chromosome rearrangement.
    • PGT-M usually requires a prior genetic diagnosis and may need family DNA or a probe build.
    • Both tests are performed on a few cells removed from an embryo, usually at the blastocyst stage.
    • Results are reported as probabilities or classifications, not certainties.

    What each test is designed to do

    PGT-A (preimplantation genetic testing for aneuploidy) counts chromosomes. It estimates whether an embryo has the expected number of chromosomes or an abnormal number, such as trisomy or monosomy. It does not read the full DNA sequence and does not rule out all genetic conditions.

    PGT-M (preimplantation genetic testing for monogenic disorders) looks for a specific gene change that is known to cause a condition in your family. It is used when there is a confirmed diagnosis, such as cystic fibrosis, spinal muscular atrophy, thalassaemia, or another inherited condition. Because the target is specific, the laboratory needs to know exactly what it is looking for before testing begins.

    PGT-SR (for structural rearrangements) is a third category. It is considered when a parent has a balanced translocation, inversion, or similar chromosome rearrangement. It is mentioned here because it is often discussed alongside PGT-A and PGT-M, but it is a separate test with its own indications.

    Side-by-side comparison: indications, lab steps, and decision triggers

    Feature PGT-A PGT-M
    Main question Does this embryo have the expected number of chromosomes? Did this embryo inherit the specific familial gene change?
    Typical indications Advanced maternal age, repeated implantation failure, recurrent pregnancy loss, or a history of chromosomal abnormality in a prior pregnancy. A known inherited condition in the family, a confirmed carrier status in one or both parents, or a prior affected child.
    What the lab needs first Embryo biopsy sample; no prior family testing is usually required. A confirmed genetic diagnosis, the exact gene change, and often DNA samples from family members to build a test probe.
    Laboratory steps Embryo culture to blastocyst, trophectoderm biopsy, cell preparation, whole-genome amplification, then chromosome analysis. Embryo culture to blastocyst, trophectoderm biopsy, cell preparation, whole-genome amplification, then targeted analysis for the known gene change.
    Result format Classification such as euploid, aneuploid, mosaic, or inconclusive. Affected, unaffected, carrier, or inconclusive, depending on the condition and test design.
    Main limitations Does not detect all genetic conditions; mosaicism and inconclusive results can occur; does not guarantee implantation or live birth. Requires a known target; probe development can take time; does not screen for unrelated chromosomal conditions unless combined with PGT-A.
    Decision trigger Age-related risk, repeated loss, or prior aneuploid pregnancy. Family history, carrier status, or a known diagnosis that could be passed on.

    How the laboratory process differs

    Both tests begin the same way. The embryo is cultured, usually to day 5 or 6, and a small number of cells are removed from the outer layer (trophectoderm). The cells are prepared and their DNA is amplified so there is enough material to analyse.

    From there, the paths diverge. PGT-A uses a genome-wide method to estimate chromosome number. PGT-M uses a targeted method designed around the specific gene change in your family. For PGT-M, the laboratory often needs to build a custom probe, which can require blood or saliva samples from you, your partner, and sometimes a family member. This preparation step can add time before the embryo testing itself can be done.

    Some clinics offer combined testing when both chromosomal number and a specific familial condition are concerns. Whether this is appropriate depends on your history and the laboratory’s capabilities, and it should be discussed with your clinician.

    Understanding results and uncertainty

    PGT results are not always a simple yes or no. PGT-A can report a mosaic result, meaning the embryo has a mix of cells with different chromosome numbers. The clinical meaning of mosaicism is still an area of active research, and clinics may handle mosaic embryos differently. An inconclusive result can also occur when the sample does not provide enough information.

    PGT-M results are usually clearer for the specific condition being tested, but they still do not guarantee a healthy child. They tell you whether the embryo inherited the gene change the test was designed to find. They do not rule out other genetic conditions, pregnancy complications, or health issues unrelated to the tested gene.

    No PGT test can guarantee implantation, pregnancy, live birth, or child health. Your clinic should explain the detection rate, the chance of an inconclusive result, and what a result would mean for your transfer decisions.

    Alternatives and when testing may not be needed

    PGT is not a required step for every IVF cycle. Some patients choose to transfer untested embryos, especially when there is no clear indication and the number of available embryos is limited. Others use donor gametes, genetic counselling, or prenatal testing instead of, or in addition to, PGT.

    For some families, the more important first step is genetic counselling to clarify the actual risk and the options available. A genetic counsellor can help you understand whether PGT-M is technically possible, what the test can detect, and what the alternatives are.

    Questions to ask your clinic in Thailand

    • Based on my history, which PGT test—if any—do you recommend, and why?
    • What are the indications you are using to make that recommendation?
    • For PGT-M, what preparation is needed, and how long does probe development take?
    • How do you report mosaic or inconclusive results, and what are my options then?
    • What are the costs of the test, the biopsy, and any additional laboratory work?
    • What is your policy on transferring untested or mosaic embryos?
    • Do you provide genetic counselling, or can you refer me to a counsellor?
    • What documents or consent forms will I need to provide?

    Next-step checklist

    1. Gather your personal and family medical history, including any prior genetic test results.
    2. Ask your clinic whether genetic counselling is available before you decide.
    3. Clarify which test is being recommended and what question it answers.
    4. Ask about laboratory timelines, especially if PGT-M probe development is needed.
    5. Request a written summary of costs, including biopsy, testing, and storage fees.
    6. Confirm how results will be explained and what happens if the result is inconclusive.
    7. Review the clinic’s consent process and any legal or travel requirements with the clinic directly.

    Choosing between PGT-A and PGT-M is not a matter of one test being better than the other. They answer different questions. The right choice depends on your medical history, your family’s genetic information, and what you hope to learn. Start with a clinical assessment and a clear conversation about what each test can and cannot do. For more context, see our PGT in Thailand overview, browse the guides, or check the FAQ.

    Frequently asked questions

    Can I have PGT-A and PGT-M at the same time?

    Sometimes, yes. Combined testing may be possible when both chromosomal number and a specific familial condition are concerns. Whether it is appropriate depends on your history, the laboratory's methods, and the quality of the embryo sample. Your clinic can explain whether combined testing is available and what it would involve.

    Do I need PGT-M if no one in my family has a genetic condition?

    PGT-M is designed for a known inherited condition. If there is no known condition, there is usually no target for the test. A genetic counsellor can help clarify whether any testing is indicated based on your personal and family history.

    What does a mosaic result on PGT-A mean?

    A mosaic result means the embryo has a mix of cells with different chromosome numbers. The clinical significance is still being studied, and clinics may have different policies about transferring mosaic embryos. Ask your clinic how they interpret and report mosaicism.

    Does PGT guarantee a healthy baby?

    No. PGT can provide information about specific chromosomal or genetic findings, but it cannot guarantee implantation, pregnancy, live birth, or child health. It does not detect every possible genetic condition. Your clinic should explain the limitations for your situation.

    How long does PGT-M take compared to PGT-A?

    PGT-M often requires additional preparation, such as building a custom probe, which can add time before testing. PGT-A does not usually require this step. Exact timelines vary by laboratory and should be confirmed with your clinic.

  • PGT and IVF Success Rates in Thailand: What Testing Can and Cannot Change

    PGT does not guarantee a live birth, and it does not improve the quality of any single embryo. What it can do is give you and your clinician more information about which embryos are most likely to be chromosomally normal, so that the embryo chosen for transfer is selected on evidence rather than appearance alone. Whether that changes your personal chance of a live birth depends on your age, your reason for testing, how many embryos you have, and how your clinic reports its results. This guide explains the moving parts so you can ask better questions in Thailand.

    At a glance

    • PGT-A screens embryos for extra or missing chromosomes; it does not repair them.
    • PGT-M looks for a specific inherited condition known to run in a family.
    • PGT-SR looks at chromosome rearrangements such as translocations.
    • Testing may reduce the chance of transferring an embryo that is chromosomally abnormal, but it cannot promise pregnancy, live birth or a healthy child.
    • Age remains one of the strongest influences on both embryo chromosome status and live birth odds.
    • Success-rate figures are only comparable when the definitions behind them match.

    What PGT actually does

    Preimplantation genetic testing (PGT) is carried out on a small sample of cells taken from an embryo during IVF, usually at the blastocyst stage. The sample is analysed in a genetics laboratory, and the result is used to help decide which embryo(s) to consider for transfer.

    There are three main categories:

    • PGT-A (aneuploidy screening) — checks for an abnormal number of chromosomes. It is the type most often discussed in relation to IVF success rates.
    • PGT-M (monogenic disease) — looks for a specific gene variant linked to a known inherited condition in the family.
    • PGT-SR (structural rearrangement) — looks at chromosome rearrangements, such as a translocation, that may affect embryo viability.

    Each type answers a different question. PGT-A is a screening test, not a diagnosis of the embryo’s future. PGT-M and PGT-SR are more targeted and are usually considered when there is a specific family or genetic history.

    What PGT can and cannot change about live birth odds

    It helps to separate two ideas that are often mixed together.

    What PGT can change: the information available at the moment of transfer. If several embryos are available, testing may help identify those with a normal chromosome complement, so the transfer decision is based on more than embryo appearance or development speed.

    What PGT cannot change: the underlying biology of your eggs, sperm or embryos. Testing does not make an abnormal embryo normal, does not increase the number of usable embryos, and does not remove the many other reasons why an embryo may not implant or a pregnancy may not continue. It also cannot guarantee that a transferred embryo will lead to a live birth.

    This is why two patients with the same PGT result can have very different outcomes. The test is one input among many.

    How age interacts with PGT outcomes

    Age affects IVF in two connected ways. First, it influences how many eggs are available and how many become usable embryos. Second, it influences the proportion of those embryos that are chromosomally normal. Because PGT-A reports on chromosome status, its results tend to reflect these age-related patterns.

    In practical terms, this means:

    • Younger patients often have more embryos to test, which can make selection more meaningful.
    • Older patients may have fewer embryos, so there may be less to choose between — and sometimes no embryo suitable for transfer after testing.
    • A normal PGT-A result does not cancel out the effect of age on other factors, such as uterine environment or overall health.

    PGT is therefore not a way to “reset” age-related odds. It is a way to gather information within the limits of the embryos you have.

    How Thai clinics report success rates

    Success-rate figures are only useful if you know what is being counted. When you see a number described as a “PGT success rate” or “live birth rate”, ask which of the following it refers to:

    • The denominator — is it per cycle started, per egg retrieval, per embryo transfer, or per patient?
    • The numerator — is it a positive pregnancy test, a clinical pregnancy, an ongoing pregnancy, or a live birth?
    • The population — does it include all patients, or only a selected group such as younger patients or those with many embryos?
    • The testing strategy — were all embryos tested, or only some? Was a fresh or frozen transfer used?
    • The time period — rates can shift as laboratory methods and patient mix change.

    Two clinics can quote very different numbers while both being accurate, simply because they are measuring different things. A high figure based on a narrow, favourable group is not directly comparable with a lower figure based on all comers.

    Questions to ask a clinic in Thailand

    These questions are designed to help you compare like with like, and to understand what a clinic’s numbers actually describe.

    1. For patients similar to me — same age range, same reason for treatment — what outcomes do you typically see?
    2. How do you define and calculate your live birth rate? Per transfer, per retrieval, or per patient?
    3. Do your published or quoted figures include PGT and non-PGT cycles separately?
    4. What proportion of your PGT cycles result in no embryo available for transfer?
    5. Which PGT types do you offer, and who performs the genetic analysis?
    6. What are the limitations of PGT in my situation, and what would you recommend if I chose not to test?
    7. What are the costs of testing, and are they separate from the IVF cycle costs?
    8. What is your policy on counselling before and after PGT?

    Ask for the answers in writing where possible. A clinic that is comfortable explaining its definitions is usually easier to work with.

    Alternatives and limitations to consider

    PGT is one option, not the only one. Depending on your situation, you and your clinician may also discuss:

    • Transfer without PGT — using embryo development and morphology to guide selection.
    • Different transfer strategies — for example, fresh versus frozen embryo transfer.
    • Further diagnostic testing — such as carrier screening for you or your partner, which may change which PGT type is relevant.
    • Donor eggs or sperm — where these are legal and available, and where they fit your circumstances.

    Limitations to keep in mind:

    • PGT-A is a screening test and can occasionally give an unclear or inconclusive result.
    • Mosaic results — where some cells are normal and others are not — require careful interpretation and specialist advice.
    • Testing adds cost, time and laboratory steps to an IVF cycle.
    • No test can guarantee a healthy child or a successful pregnancy.

    Planning your next steps

    If you are weighing PGT as part of IVF in Thailand, a practical sequence looks like this:

    1. Clarify your reason for considering PGT — age, recurrent loss, family history, or something else.
    2. Ask whether PGT-A, PGT-M or PGT-SR is relevant to that reason.
    3. Request outcome data that matches your age range and situation, with clear definitions.
    4. Ask what happens if no embryo is suitable for transfer after testing.
    5. Confirm the full cost picture, including genetic counselling and any additional laboratory fees.
    6. Check how results and counselling will be communicated to you, especially if you are travelling from abroad.
    7. Take time to decide. PGT is a choice, not a requirement.

    For more context, see our guides on IVF success rates in Thailand, PGT in Thailand, and our patient guides. If you have a specific question, our FAQ may help.

    Frequently asked questions

    Does PGT improve IVF success rates?

    PGT can help select embryos with a normal chromosome complement for transfer, which may be useful in some situations. However, it does not guarantee pregnancy or a live birth, and it does not change the underlying quality of your embryos. Whether it improves your personal odds depends on your age, the number of embryos available, and your reason for testing. Discuss the expected benefit with your clinician.

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

    PGT-A screens for abnormal chromosome number. PGT-M looks for a specific inherited condition known to run in a family. PGT-SR looks at structural chromosome rearrangements such as translocations. Each answers a different question, and the right one for you depends on your history and test results.

    How should I interpret success rates quoted by clinics in Thailand?

    Ask what the number measures: per cycle, per retrieval, per transfer, or per patient; whether it counts pregnancy or live birth; and which patients are included. Rates based on selected groups are not directly comparable with rates based on all patients. Request definitions in writing so you can compare fairly.

    Can PGT tell me whether my embryo will lead to a healthy baby?

    No. PGT provides information about chromosome number or a specific genetic variant, but it cannot predict all aspects of embryo development, pregnancy outcome or child health. It is one part of a broader clinical picture, and counselling can help you understand its limits.

    What happens if no embryo is suitable for transfer after PGT?

    This is a possible outcome, especially when few embryos are available. Ask your clinic in advance how they handle this situation, what alternatives exist, and what support or counselling is offered. Knowing the plan beforehand can help you prepare.

  • PGT-A IVF in Thailand: A Guide to Chromosome Screening, Indications, and Embryo Transfer Decisions

    PGT-A (preimplantation genetic testing for aneuploidy) is a laboratory test that checks embryos created through IVF for an abnormal number of chromosomes. It is not a treatment that improves embryo quality, and it does not guarantee a pregnancy. Instead, it provides information that you and your clinician can use when deciding which embryo(s) to transfer. In Thailand, PGT-A is offered at some fertility clinics, but availability, laboratory arrangements, and eligibility criteria vary. This guide explains the general process, common indications, and the questions worth asking before you commit.

    At a glance

    • What it is: A test on a few cells taken from an embryo, usually at the blastocyst stage.
    • What it looks for: Extra or missing whole chromosomes (aneuploidy).
    • What it does not do: It does not fix embryo chromosomes, guarantee implantation, or rule out all genetic conditions.
    • Who may be offered it: Often discussed for older patients, recurrent miscarriage, repeated implantation failure, or after severe male factor infertility — but indications are individual.
    • Key decision point: Whether the information would change which embryo is transferred or whether you would consider transferring an embryo with a detected abnormality.

    What PGT-A actually tests

    Human embryos often have the wrong number of chromosomes. This is called aneuploidy. Most aneuploid embryos do not implant, or they may lead to miscarriage. A small number can result in a live birth with a chromosome condition such as Down syndrome, but many others stop developing before birth.

    PGT-A counts chromosomes. It does not read individual genes, so it cannot detect single-gene disorders like cystic fibrosis or Huntington’s disease. It also does not detect structural chromosome rearrangements such as translocations. Those require different tests: PGT-M for monogenic (single-gene) conditions and PGT-SR for structural rearrangements. If you have a known genetic condition in the family, your clinic may recommend PGT-M instead of, or in addition to, PGT-A.

    Common indications for PGT-A

    PGT-A is not routinely recommended for every IVF patient. Guidelines from professional bodies generally suggest it may be considered in specific situations, and the decision should be made with a qualified clinician who knows your history. Commonly discussed indications include:

    • Advanced maternal age: The chance of aneuploidy increases with age, so some clinics discuss PGT-A more often with older patients.
    • Recurrent pregnancy loss: If you have had multiple miscarriages, PGT-A may be one option to explore, though it does not explain all causes.
    • Repeated implantation failure: When several good-quality embryos have not led to pregnancy, some clinicians consider PGT-A.
    • Severe male factor infertility: Some evidence suggests a higher risk of chromosome abnormalities in embryos in these cases.
    • Previous pregnancy or child with a chromosome condition: PGT-A may be discussed, though the specific condition matters.
    • Patient preference after counselling: Some patients want as much information as possible before transfer, even without a specific indication.

    In Thailand, as elsewhere, not every clinic offers PGT-A, and some may have their own criteria. It is reasonable to ask why PGT-A is being recommended in your case and what the alternatives are.

    The PGT-A process in Thailand: step by step

    The exact sequence can vary by clinic, but the general pathway looks like this:

    1. IVF stimulation and egg retrieval: You undergo standard IVF, including medication to stimulate the ovaries and a procedure to collect eggs.
    2. Fertilisation and embryo culture: Eggs are fertilised in the laboratory and grown for several days, usually until the blastocyst stage (day 5 or 6).
    3. Embryo biopsy: A few cells are removed from the outer layer of the blastocyst (the trophectoderm), which will become the placenta. This is done by an embryologist. The embryo itself is not usually harmed, though biopsy carries a small risk and not all embryos survive the process.
    4. Sample preparation and testing: The biopsied cells are prepared and analysed, either at the clinic’s laboratory or at a partner genetics laboratory. The method may be next-generation sequencing (NGS) or another technique.
    5. Embryo freezing: In most cases, embryos are frozen after biopsy while waiting for results. This allows time for the test and for your uterus to be ready for transfer in a later cycle.
    6. Results and counselling: A genetic counsellor or your doctor explains the results. Embryos are usually classified as euploid (normal chromosome number), aneuploid (abnormal), or sometimes mosaic (a mix of normal and abnormal cells).
    7. Embryo transfer decision: If you have euploid embryos, one may be selected for transfer. If all embryos are aneuploid, transfer may not be recommended, and you may need to consider another cycle or other options.

    Timelines vary. Some clinics can return results within a few days; others may take longer depending on laboratory logistics. Ask your clinic for a realistic estimate.

    How results guide embryo transfer decisions

    The main purpose of PGT-A is to help choose which embryo to transfer. If you have several embryos, PGT-A may identify those with a normal chromosome number, which could improve the chance of a successful pregnancy per transfer. However, it does not guarantee success, and some euploid embryos still do not implant.

    If results show only aneuploid embryos, your clinician may advise against transferring them, as they are unlikely to lead to a healthy birth. Some clinics may discuss transferring mosaic embryos, but this is a complex area with ongoing debate. Mosaic results mean the biopsy found a mixture of normal and abnormal cells; the embryo may still be able to develop normally, but the evidence is not clear-cut. Your clinic should explain the uncertainties and help you weigh the options.

    It is also possible that PGT-A leaves you with no embryos to transfer. This is an important risk to consider before starting, both emotionally and financially.

    Limitations and alternatives

    PGT-A is a screening test, not a diagnostic one. It can produce false results, and it does not detect all genetic problems. It also does not improve the quality of your embryos; it only provides information. Some studies suggest PGT-A may not improve live birth rates for all patients, and it may reduce the number of embryos available for transfer.

    Alternatives include:

    • Transferring embryos without PGT-A: Many healthy babies are born from untested embryos.
    • Ultrasound and maternal blood screening during pregnancy: These can check for some chromosome conditions after pregnancy is established.
    • Diagnostic tests during pregnancy: Such as chorionic villus sampling or amniocentesis, which are more invasive but can confirm a diagnosis.
    • PGT-M or PGT-SR: If you have a known single-gene disorder or structural rearrangement, these may be more appropriate.

    Discuss the pros and cons with a genetic counsellor or your fertility doctor. They can help you understand how PGT-A might apply to your specific situation.

    Questions to ask a clinic in Thailand

    Before choosing a clinic for PGT-A, consider asking:

    • Is PGT-A offered at this clinic, and which laboratory performs the testing?
    • What are the clinic’s criteria for recommending PGT-A? Do I meet them?
    • What is the biopsy timing and technique? Who performs it?
    • How are results reported, and what support is available to interpret them?
    • What happens if all embryos are aneuploid or mosaic?
    • What are the additional costs for biopsy, testing, and freezing?
    • How long does it take to get results?
    • What are the clinic’s success rates for PGT-A cycles, and how do they compare with untested cycles?

    Be cautious of any clinic that guarantees a baby or quotes success rates without context. No treatment can promise a live birth.

    Next steps

    If you are considering PGT-A in Thailand, start by gathering information and asking direct questions. You may wish to:

    • Review your medical history with a fertility specialist to see if PGT-A is relevant for you.
    • Ask for a written summary of the process, costs, and possible outcomes.
    • Consider speaking with a genetic counsellor, either at the clinic or independently.
    • Explore our PGT in Thailand page for more context, browse our guides, and check the FAQ for common questions.

    PGT-A is a personal decision. Take your time, ask for evidence, and choose a clinic that respects your questions and your autonomy.

    Frequently asked questions

    Is PGT-A required for IVF in Thailand?

    No. PGT-A is an optional test, not a required part of IVF. Whether it is offered or recommended depends on your medical history and the clinic's practice. Some patients choose IVF without PGT-A.

    Does PGT-A improve the chance of having a baby?

    PGT-A can help select embryos with a normal chromosome number for transfer, which may improve the chance per transfer in some situations. However, it does not guarantee a pregnancy or a healthy baby, and it may not improve live birth rates for all patients. Discuss the evidence with your clinician.

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

    PGT-A screens for extra or missing whole chromosomes (aneuploidy). PGT-M tests for a specific single-gene disorder, such as cystic fibrosis. PGT-SR tests for structural chromosome rearrangements, such as translocations. Your clinic can advise which, if any, is appropriate for you.

    What happens if PGT-A shows all embryos are abnormal?

    If all embryos are aneuploid, transfer is usually not recommended because they are unlikely to lead to a healthy birth. Your clinician will discuss options, which may include another IVF cycle, using donor eggs or sperm, or choosing not to pursue further treatment. This is a difficult situation, and counselling support is important.

    Can PGT-A detect all genetic problems?

    No. PGT-A only looks at chromosome number. It does not detect single-gene disorders, structural rearrangements, or many other genetic conditions. It also cannot predict all aspects of a child's health.

  • PGT IVF in Thailand: A Plain-English Guide to Genetic Testing Before Transfer

    PGT (preimplantation genetic testing) is a laboratory step that can be added to an IVF cycle. After eggs are fertilised and embryos begin to develop, a small number of cells may be removed from each embryo and tested for specific chromosome or gene findings. In Thailand, as elsewhere, PGT is optional rather than automatic: it is a decision made with your treating clinician, based on your history, your reasons for testing and what the result could realistically change. PGT cannot guarantee a pregnancy, a live birth or a healthy child, and it is not necessary or suitable for everyone.

    At a glance

    • PGT-A looks at chromosome number (for example, extra or missing chromosomes).
    • PGT-M looks for a known single-gene condition that runs in a family.
    • PGT-SR relates to known structural chromosome rearrangements, such as a translocation.
    • Testing happens in the laboratory after fertilisation, before any embryo transfer.
    • Results are probabilities and risk information, not promises.
    • Availability, eligibility, cost and timelines vary by clinic and must be confirmed directly.

    What PGT is, and what it is not

    PGT is a screening or diagnostic laboratory technique performed on embryos created through IVF. It is not a treatment for infertility, and it does not improve the quality of an embryo. Instead, it provides additional information that you and your clinician may use when deciding which embryo(s) to consider transferring, or whether to consider other options.

    It is important to separate three ideas that are sometimes blurred together:

    • What the test looks at: chromosome number, a specific gene change, or a structural chromosome arrangement.
    • What the result means: a laboratory finding that carries a certain level of uncertainty.
    • What happens next: a clinical decision that depends on your full situation, not on the test result alone.

    PGT is not a guarantee of success, and it does not replace other forms of prenatal testing or genetic counselling. Some patients choose IVF without PGT; others choose PGT for specific reasons. Both paths can be reasonable.

    The three main types of PGT

    The umbrella term “PGT” covers different tests with different purposes. The table below summarises the broad differences. Your clinic will explain which, if any, applies to you.

    Type What it looks at Typical reason it is discussed Key limitation
    PGT-A Chromosome number (aneuploidy screening) Age-related risk, recurrent implantation failure or recurrent pregnancy loss, or when a clinic offers it as an option It does not read the whole genetic code, and it cannot guarantee a healthy pregnancy
    PGT-M A known single-gene condition in the family When a specific inherited condition is known and a lab can build a test for it Requires prior genetic information and lab setup; not all conditions are equally straightforward
    PGT-SR Structural chromosome rearrangements (for example, translocations) When a parent carries a known structural rearrangement Interpretation can be complex; results need specialist explanation

    Some clinics may also discuss other laboratory techniques, such as mitochondrial DNA testing or polygenic risk scoring. These are not the same as PGT-A, PGT-M or PGT-SR, and their clinical role is still debated. Ask your clinic to explain exactly what is being offered and what evidence supports it.

    How PGT fits into an IVF cycle in Thailand

    The exact sequence varies by clinic, but the general shape of a PGT cycle is similar in most settings. The steps below are a planning framework, not a protocol. Your clinic will give you its own instructions.

    1. Initial consultation and testing. You discuss your history, reasons for considering PGT, and whether it is appropriate. You may be asked to provide prior genetic test results or family information.
    2. Ovarian stimulation and monitoring. Medication is used to encourage multiple eggs to mature, with monitoring scans and blood tests. Your clinic decides the protocol.
    3. Egg retrieval and fertilisation. Eggs are collected and combined with sperm in the laboratory to create embryos.
    4. Embryo development. Embryos are observed for several days. Not all fertilised eggs develop into embryos suitable for testing or transfer.
    5. Biopsy. If PGT is planned, a few cells are removed from each embryo at a suitable stage. This is a laboratory procedure.
    6. Testing and reporting. The sampled cells are analysed. The time needed depends on the test and the laboratory.
    7. Results discussion. You and your clinician review the findings, including any uncertainty, and discuss options.
    8. Transfer or storage. Depending on results and your preferences, an embryo may be transferred, frozen for later, or not used. Some embryos may be reported as “no result” or “inconclusive,” which requires a further conversation.

    Because PGT adds laboratory steps, it can extend the overall timeline and add cost. The exact amounts and waiting times are clinic-specific and should be confirmed in writing before you commit.

    Who might consider PGT — and who might not

    PGT is a personal decision. There is no single rule that applies to everyone. The following categories are commonly discussed, but they are conversation starters, not eligibility criteria.

    • Known inherited condition in the family: PGT-M may be discussed when a specific gene change is known.
    • Known structural chromosome rearrangement: PGT-SR may be discussed when a parent carries a translocation or similar finding.
    • History of recurrent pregnancy loss or repeated implantation failure: PGT-A may be offered as one option, though evidence and guidelines vary.
    • Advanced maternal age: Some clinics discuss PGT-A because chromosome number errors become more common with age, but it is not a guarantee of a better outcome.
    • Previous pregnancy or child with a chromosome condition: A clinician may discuss PGT-A or other testing.
    • No specific risk factors: Some patients choose PGT for personal reasons; others choose not to. Both choices can be valid.

    PGT is generally not a first-line recommendation for every IVF patient. It may be less useful, or not useful, when there is no clear question the test can answer. A genetic counsellor or your treating clinician can help you weigh the potential benefits and limitations.

    Understanding PGT results and their limits

    PGT results are laboratory findings, not diagnoses of a future child. They can be reported in different ways, and the meaning depends on the test and the laboratory.

    • “Normal” or “euploid” (PGT-A): The tested cells showed the expected number of chromosomes. This reduces, but does not eliminate, the chance of a chromosome condition. It cannot rule out all genetic conditions, and it does not guarantee a pregnancy.
    • “Abnormal” or “aneuploid” (PGT-A): The tested cells showed an extra or missing chromosome. This information may influence which embryo is considered for transfer, but it is not a prediction of a child’s health or abilities.
    • “Mosaic”: The tested cells showed a mix of normal and abnormal findings. Mosaic results are complex, and their interpretation is an active area of discussion. Ask your clinic what a mosaic result would mean in your case.
    • “No result” or “inconclusive”: The test did not produce a clear answer. This can happen for technical reasons. Your clinic will explain the options, which may include re-testing, transferring without a result, or not using the embryo.
    • PGT-M and PGT-SR results: These are usually reported in relation to the specific condition or rearrangement being tested. They require careful explanation by a specialist.

    No test is perfect. PGT can produce false results in rare cases, and it cannot detect every possible genetic or health issue. For this reason, many clinics still recommend standard prenatal screening or diagnostic testing during pregnancy, such as ultrasound, blood tests, or chorionic villus sampling/amniocentesis, depending on your situation.

    Alternatives and complementary options

    PGT is one option among several. Depending on your situation, you might also discuss:

    • IVF without PGT: Transferring embryos based on standard laboratory assessment.
    • Donor eggs or donor sperm: Which may change the genetic questions being considered.
    • Prenatal screening and diagnosis: Tests during pregnancy that can provide information about the fetus.
    • Genetic counselling: A conversation with a specialist to understand risks, inheritance patterns and testing options.
    • Preimplantation genetic testing for a specific condition (PGT-M) using a previously established lab protocol: Sometimes a lab needs time to prepare a custom test.

    These options are not mutually exclusive. Your clinician can help you understand how they might fit together.

    Practical questions to ask a clinic in Thailand

    Because PGT services, laboratory arrangements and pricing vary, it helps to ask direct questions. You can use the list below as a starting point.

    • Which type of PGT are you recommending for my situation, and why?
    • What is the evidence that this test will change my care or outcome?
    • Who performs the biopsy and the laboratory analysis? Is any part sent to another laboratory?
    • What are the possible results, including “no result” or “mosaic,” and what would each mean for my options?
    • What are the total costs, including consultation, medication, laboratory, biopsy, testing, storage and transfer? Are there separate fees for genetic counselling?
    • How long does testing take, and how does it affect the overall timeline?
    • What happens to embryos that are not transferred or not used?
    • What are the legal and regulatory requirements in Thailand for my situation, and what documents should I prepare?
    • Do you recommend prenatal testing during pregnancy even after PGT?
    • Can I speak with a genetic counsellor before deciding?

    Ask for written information where possible, and take time to consider your options. It is reasonable to seek a second opinion.

    Next-step checklist

    • Clarify your personal reasons for considering PGT.
    • Gather any prior genetic test results or family history information.
    • Ask your clinic which PGT type, if any, is relevant to you.
    • Request a clear cost breakdown and timeline in writing.
    • Ask about the laboratory’s experience and quality processes.
    • Discuss the limits of testing and what a result can and cannot tell you.
    • Consider genetic counselling before making a decision.
    • Confirm legal, travel and documentation requirements with the clinic and relevant authorities.

    PGT can be a useful tool in some situations, but it is not a guarantee and not a universal requirement. The most important step is an honest conversation with a qualified clinician who knows your history and can explain what testing might realistically offer you.

    Frequently asked questions

    Is PGT the same as IVF?

    No. IVF is the process of creating embryos outside the body. PGT is an optional laboratory test that can be performed on those embryos before transfer. You can have IVF without PGT.

    Does PGT guarantee a healthy baby?

    No. PGT can provide information about specific chromosome or gene findings, but it cannot guarantee a pregnancy, a live birth or a child without any health condition. It does not replace prenatal testing, and no test is perfect.

    Who is PGT suitable for?

    PGT may be discussed for several reasons, such as a known inherited condition in the family, a known structural chromosome rearrangement, a history of recurrent pregnancy loss, or advanced maternal age. It is not automatically recommended for everyone, and suitability is a clinical decision made with your treating clinician.

    What does a “mosaic” PGT result mean?

    A mosaic result means the tested cells showed a mix of normal and abnormal findings. The interpretation is complex and depends on the specific situation. Your clinic or a genetic counsellor should explain what it could mean for your options.

    Can I have PGT in Thailand if I am an international patient?

    Many international patients travel to Thailand for IVF, and some clinics offer PGT. Availability, eligibility, legal requirements, documentation and costs vary by clinic and by your individual situation. You should confirm these details directly with the clinic and, where relevant, with the appropriate authorities before making travel plans.

  • IVF for Recurrent Miscarriage in Thailand: How PGT-A Fits Into the Decision

    Recurrent miscarriage is usually defined as two or more pregnancy losses, depending on which guideline you follow. When couples search for IVF for recurrent miscarriage in Thailand, they are often trying to answer one question: could embryo testing reduce the chance of another loss? IVF with PGT-A is one option that some clinics discuss, but it is not a guaranteed solution and it is not right for every situation. This guide explains what PGT-A does, how it differs from other embryo tests, where the evidence is uncertain, and how to plan a careful conversation with a clinic in Thailand.

    At a glance

    • Recurrent miscarriage has many possible causes, and not all of them are chromosomal.
    • PGT-A screens embryos for extra or missing chromosomes before transfer.
    • PGT-A does not guarantee a pregnancy, a live birth, or a healthy child.
    • PGT-M and PGT-SR are different tests used for different reasons.
    • IVF itself carries risks and costs, and it does not remove all causes of loss.
    • Ask a clinic directly about its own results, criteria, and limitations.

    Why recurrent miscarriage happens

    Pregnancy loss can result from chromosomal abnormalities in the embryo, structural issues in the uterus, hormonal or metabolic conditions, blood-clotting disorders, infections, immune factors, or a combination of these. In many cases, no single cause is identified even after a full evaluation. Age is one of the strongest factors linked to chromosomal errors in embryos, which is why the chance of loss tends to rise with maternal age.

    Because the causes are so varied, no single test or treatment addresses every situation. This is the main reason a careful evaluation usually comes before any decision about IVF or embryo testing.

    What PGT-A actually does

    PGT-A stands for preimplantation genetic testing for aneuploidy. Aneuploidy means an embryo has an abnormal number of chromosomes. During an IVF cycle, a few cells are removed from an embryo, usually at the blastocyst stage, and those cells are tested in a laboratory. The result is reported as euploid (the expected number of chromosomes), aneuploid (an abnormal number), or sometimes mosaic (a mix of cells with different chromosome numbers).

    The purpose of PGT-A is to help select which embryos to transfer. It is a screening test, not a treatment. It does not change the embryo, and it does not fix anything. It simply provides information that a clinician may use when deciding which embryo to transfer first.

    PGT-A, PGT-M, and PGT-SR: what is the difference?

    Test What it looks at Typical reason it is discussed
    PGT-A Chromosome number across the embryo Recurrent miscarriage, advanced maternal age, repeated IVF failure
    PGT-M A specific known gene variant A family history of a single-gene disorder
    PGT-SR Chromosome structure, such as a translocation A known structural chromosome rearrangement in a parent

    These tests are not interchangeable. PGT-A does not detect single-gene disorders, and PGT-M does not screen for aneuploidy across all chromosomes. If you have a known genetic condition in the family, a different test may be more relevant.

    How PGT-A is used in recurrent miscarriage

    Some miscarriages are caused by chromosomal abnormalities in the embryo, and PGT-A can identify embryos with an abnormal chromosome number before transfer. In theory, transferring only euploid embryos could reduce the chance of miscarriage caused by aneuploidy. In practice, the picture is more complicated.

    PGT-A does not prevent miscarriage from other causes, such as uterine problems, clotting disorders, or immune factors. It also does not guarantee that a euploid embryo will implant or develop normally. Some embryos reported as euploid still fail to implant or result in loss, and some mosaic embryos can develop into healthy pregnancies. This is why PGT-A is best understood as one piece of information, not a complete answer.

    What the evidence does and does not show

    Research on PGT-A has produced mixed results. Some studies suggest a possible reduction in miscarriage rates per transfer, while others show no clear improvement in live birth rates when compared with transferring untested embryos. The evidence is strongest for certain groups, such as women of advanced maternal age, and less clear for others.

    Because the evidence is not uniform, professional guidelines generally do not recommend PGT-A as a routine test for everyone with recurrent miscarriage. It is usually presented as an option to discuss, weighing potential benefits against costs, the possibility of having no euploid embryos to transfer, and the chance of a false or uncertain result.

    Alternatives and complementary steps

    Before or alongside IVF with PGT-A, a clinic may suggest other evaluations. These can include:

    • Testing for chromosomal structure in both partners
    • Imaging of the uterus to check for structural issues
    • Blood tests for thyroid function, diabetes, or clotting disorders
    • Review of medications, lifestyle factors, and previous pregnancy records
    • Genetic counseling if there is a family history of a known condition

    These steps are not alternatives to PGT-A in a strict sense, but they address different possible causes. A complete plan often combines several approaches rather than relying on one test.

    Practical questions to ask a clinic in Thailand

    When you contact a clinic, ask for clear answers in writing where possible. Useful questions include:

    • What is your definition of recurrent miscarriage, and what evaluation do you recommend first?
    • Do you offer PGT-A, PGT-M, and PGT-SR, and which would you recommend for my situation?
    • What are your laboratory’s typical results for patients with my history?
    • What happens if no euploid embryos are available after testing?
    • How do you handle mosaic results, and what are the trade-offs?
    • What are the total costs, including IVF, testing, medications, and any additional fees?
    • What are the success rates for patients with recurrent miscarriage at your clinic, and how are they measured?
    • What support is available if the cycle does not result in a pregnancy?

    Be cautious of any clinic that promises a specific outcome or presents PGT-A as a guaranteed solution. No test can promise a healthy baby.

    Planning and next steps

    If you are considering IVF for recurrent miscarriage in Thailand, a sensible sequence is:

    1. Gather your previous medical records, including any miscarriage testing or imaging.
    2. Ask for a full evaluation of possible causes before committing to IVF.
    3. Discuss whether PGT-A is likely to change your management, and how.
    4. Ask about costs, timelines, and what happens if testing leaves no embryos to transfer.
    5. Consider a second opinion if the advice feels rushed or overly certain.
    6. Confirm visa, travel, and legal requirements with the relevant authorities, as these can change.

    For more background, see our pages on PGT in Thailand, our patient guides, and our frequently asked questions.

    Frequently asked questions

    Does PGT-A prevent miscarriage?

    No. PGT-A can identify embryos with an abnormal number of chromosomes, which is one possible cause of miscarriage. It does not prevent miscarriage from other causes, and it cannot guarantee that a transferred embryo will implant or develop into a healthy pregnancy.

    Is PGT-A recommended for everyone with recurrent miscarriage?

    No. Professional guidelines generally do not recommend PGT-A as a routine test for all cases of recurrent miscarriage. It is usually discussed as an option, and the decision depends on your history, age, previous test results, and personal preferences.

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

    PGT-A screens for an abnormal number of chromosomes across the embryo. PGT-M looks for a specific gene variant that is known to run in a family. They are used for different reasons and are not interchangeable.

    What happens if no embryos are suitable for transfer after PGT-A?

    This is a possible outcome. If testing shows that no embryos are suitable, the cycle may end without a transfer. Ask your clinic in advance how they handle this situation and what options, including counseling and financial considerations, are available.

    Can I have IVF with PGT-A in Thailand if I am an international patient?

    Many clinics in Thailand accept international patients, but availability, requirements, and costs vary. You should confirm details directly with the clinic and check current travel and legal requirements with the relevant authorities before making plans.

  • PGT-A Results Timeline in Thailand: What to Expect and How to Plan

    For international patients undergoing IVF with PGT-A in Thailand, the wait for genetic results can feel like a pause in an otherwise active process. In general, PGT-A results are not available immediately after biopsy. The timeline depends on laboratory workflows, shipping logistics if testing is done abroad, and how your clinic communicates results. Most patients receive preliminary information within one to three weeks after biopsy, but this varies. Your treating clinic is the only reliable source for your specific timeline. This guide explains the typical steps, what may affect timing, and what you can do while waiting.

    At a glance

    • Biopsy day: A few cells are removed from each embryo and prepared for testing.
    • Laboratory processing: Samples are amplified and analyzed; this may happen in Thailand or overseas.
    • Result reporting: Your clinic receives a report and schedules a consultation to discuss it.
    • Typical range: Often one to three weeks after biopsy, but this is not a promise.
    • Key variable: Whether testing is done in-house or sent to a partner laboratory.

    Step-by-step: from embryo biopsy to PGT-A results

    The process usually follows a sequence. Each step has its own timing, and delays can occur at any point.

    1. Embryo biopsy

    On the day of biopsy, the embryologist removes a small number of cells from each embryo that has reached a suitable stage, typically the blastocyst stage. This is a delicate procedure performed in the IVF laboratory. The biopsy itself does not usually add extra days to your overall IVF timeline because it is done when embryos are already being monitored.

    2. Sample preparation and shipping

    After biopsy, the cell samples are prepared for genetic analysis. If your clinic performs PGT-A in its own laboratory, the samples go directly to that lab. If testing is outsourced to a reference laboratory, the samples may need to be shipped, sometimes internationally. Shipping can add transit time and depends on courier schedules, customs clearance, and the receiving laboratory’s intake process. Your clinic should tell you whether testing is done locally or sent elsewhere.

    3. Laboratory analysis

    The laboratory amplifies the DNA from the biopsy sample and analyzes it to assess chromosome number. This step involves several quality-control checks. The time required can vary based on the laboratory’s workload, the number of embryos being tested, and whether any samples need to be re-run. Some laboratories batch samples and run them on specific days, which can affect how quickly results are ready.

    4. Report generation and review

    Once analysis is complete, the laboratory generates a report. A clinical geneticist or the laboratory director may review the findings before releasing them. Your clinic then receives the report and may need to schedule a consultation with your doctor to discuss what the results mean for your treatment plan.

    5. Results consultation

    Your clinic will typically arrange a phone, video, or in-person meeting to explain the results. This is when you can ask questions about which embryos are suitable for transfer and what the next steps might be. The timing of this consultation depends on your doctor’s availability and your own schedule.

    Factors that may affect how long PGT-A results take in Thailand

    Several variables can influence the waiting time. Because no two clinics operate identically, use these as points to clarify with your treating team.

    • Laboratory location: In-house testing may be faster than sending samples to another country.
    • Shipping and customs: International shipments can be delayed by weekends, holidays, or customs inspections.
    • Laboratory workload: Busy periods or batch schedules can extend turnaround.
    • Number of embryos: Testing more embryos may take additional time.
    • Sample quality: Occasionally a sample may not provide enough DNA, requiring a repeat.
    • Clinic communication: How and when your clinic shares results can vary.

    Typical timeline overview

    The table below outlines a general sequence. It does not represent a guarantee for any clinic or patient. Always confirm specific timeframes with your treating clinic.

    Stage What happens Typical timeframe (general guide)
    Biopsy Cells removed from embryos Day 5 or 6 after fertilization
    Sample preparation Cells prepared for analysis Same day or next day
    Shipping (if applicable) Samples sent to testing laboratory Varies; may add several days
    Laboratory analysis DNA amplification and analysis Several days to about two weeks
    Report and review Report generated and checked One to a few days
    Results consultation Discussion with your doctor Scheduled based on availability

    Planning your travel and next steps while you wait

    If you are an international patient, you may be planning to stay in Thailand until results are ready or to return home and receive results remotely. Both approaches have practical considerations.

    • Staying in Thailand: Confirm with your clinic how long they recommend you remain in the country. Ask whether results can be discussed locally and whether any follow-up procedures (such as a frozen embryo transfer) can be scheduled during the same trip.
    • Returning home: Ask how results will be communicated (secure email, phone, video call) and what time zone considerations apply. Clarify whether a follow-up appointment can be done remotely.
    • Visa and entry rules: These are time-sensitive and depend on your nationality. Check with the relevant embassy or immigration authority for current requirements. Your clinic may provide a letter for visa purposes, but they cannot give legal advice.
    • Costs: PGT-A is often an additional cost to IVF. Ask your clinic for a written breakdown of what is included and what may be charged separately, such as shipping or repeat testing.

    Questions to ask your clinic about PGT-A results timing

    Being prepared with specific questions can help you get clear answers and reduce uncertainty.

    • Is PGT-A performed in your laboratory or sent to another facility? If sent, where?
    • What is your average turnaround time from biopsy to results? (Ask for a range, not a guarantee.)
    • How will I receive my results, and who will explain them to me?
    • What happens if a sample fails to provide a result? Is there an additional cost or delay?
    • Can we schedule a follow-up consultation in advance, or do we wait until results are ready?
    • If I need to travel home before results are ready, how do we handle the consultation?
    • Are there any upcoming holidays or laboratory closures that might affect timing?

    What to do while you wait

    Waiting for results can be stressful. Here are some practical steps that may help you feel more prepared.

    • Keep a written record: Note the date of biopsy, any communication from the clinic, and questions as they arise.
    • Clarify next steps in advance: Ask your clinic what the possible outcomes are and what decisions you may need to make once results arrive.
    • Plan for both scenarios: Understand what a transfer cycle might involve if you have suitable embryos, and what alternatives exist if you do not.
    • Focus on what you can control: Maintain healthy routines, but avoid making major decisions based on uncertain timelines.
    • Reach out for support: Many patients find it helpful to talk to a counselor or join a support group.

    Frequently asked questions

    How long do PGT-A results take in Thailand?

    There is no single answer because turnaround time depends on the clinic and laboratory. In general, results may be available within one to three weeks after biopsy, but this can be longer if samples are sent to another country or if the laboratory has a backlog. Your treating clinic can give you a more specific estimate based on their current workflow.

    Can I get PGT-A results faster if I pay more?

    Some laboratories offer expedited processing for an additional fee, but this is not universal. You would need to ask your clinic whether such an option exists and what the realistic time savings might be. Even with expedited service, clinical review and consultation scheduling can add time.

    What if I need to leave Thailand before my PGT-A results are ready?

    Many clinics are accustomed to communicating results remotely for international patients. Ask your clinic how they typically handle this situation, including whether they use secure email, phone, or video calls, and how they manage time zone differences. You may also need to arrange for a follow-up consultation after you return home.

    Do holidays or weekends affect PGT-A result timing?

    Yes, laboratory schedules and courier services may be reduced on weekends and public holidays. If your biopsy or sample shipment falls near a holiday period, it may add to the waiting time. It is reasonable to ask your clinic about any upcoming closures that could affect your timeline.

    What does a PGT-A result report actually tell me?

    A PGT-A report typically indicates whether each tested embryo has a normal number of chromosomes (euploid), an abnormal number (aneuploid), or a result that is unclear (mosaic or inconclusive). Your doctor will explain what these categories mean for your specific situation and which embryos may be considered for transfer. PGT-A does not guarantee a successful pregnancy or a healthy baby.

  • PGT-A and Gender Selection in Thailand: Legal and Ethical Questions for International Patients

    Using PGT-A for gender selection in Thailand raises legal, ethical, and practical questions that vary by clinic and by patient situation. PGT-A is a laboratory test that screens embryos for chromosome number, not a guaranteed gender-selection tool. Some clinics may offer sex identification as part of PGT-A reporting, but whether that information can be used for family balancing depends on clinic policy, Thai professional guidelines, and your own reasons for requesting it. This guide explains the concepts, the limits, and the questions to ask before you plan treatment.

    At a glance

    • PGT-A screens embryos for extra or missing chromosomes; it is not a guarantee of pregnancy or a healthy child.
    • Sex identification may be possible from PGT-A data, but using it for gender selection is a separate ethical and legal question.
    • Thai clinics and professional bodies may have different policies; no single rule applies to every provider.
    • International patients should confirm clinic policy, documentation, and legal context directly with the treating clinic and, if needed, a qualified Thai legal professional.
    • Alternatives to PGT-A gender selection include accepting the natural sex ratio, using PGT-M or PGT-SR for medical reasons, or choosing not to test.

    What PGT-A actually tests

    Preimplantation genetic testing for aneuploidy (PGT-A) is performed on a small number of cells taken from an embryo during IVF. The test looks for an abnormal number of chromosomes, a condition called aneuploidy. Aneuploidy becomes more common with increasing maternal age and can reduce the chance of implantation or lead to early miscarriage. PGT-A is one of several preimplantation genetic tests; PGT-M looks for a specific inherited condition, and PGT-SR looks for structural chromosome rearrangements.

    PGT-A does not read the entire genetic code. It does not predict intelligence, appearance, or most complex traits. It also does not guarantee that a transferred embryo will implant, develop normally, or result in a live birth. Some embryos may be classified as mosaic, meaning the result is not fully normal or fully abnormal, and the interpretation of mosaicism is an evolving area of reproductive medicine.

    How sex identification fits into PGT-A

    Because PGT-A examines chromosomes, it can sometimes reveal the sex chromosomes (X and Y) along with the numbered chromosomes. In many laboratories, sex identification is reported as an additional piece of information when PGT-A is performed. However, the ability to report sex does not automatically mean the clinic will allow you to choose which embryo to transfer based on sex.

    Gender selection, also called sex selection or family balancing, is the deliberate choice of an embryo’s sex for non-medical reasons. Some clinics in Thailand may offer this as part of their IVF services, while others may restrict it to medical indications, such as avoiding a sex-linked genetic disorder. Policies can change, and they may differ between clinics, so you should ask directly rather than rely on general statements.

    Legal and ethical context in Thailand

    Thailand has laws and professional guidelines that affect assisted reproduction, but the specific rules around non-medical sex selection are not always clear-cut for international patients. Some sources suggest that sex selection for non-medical reasons is restricted or discouraged, while others indicate that certain clinics may offer it. This guide cannot provide a legal conclusion, and you should not treat it as legal advice.

    Ethically, opinions are divided. Supporters of family balancing argue that parents should be able to choose the sex of their child for family composition reasons. Critics raise concerns about gender discrimination, the potential for sex-ratio imbalance, and the idea of selecting children like consumer products. Many professional bodies recommend that non-medical sex selection be approached with caution and only after thorough counseling.

    For international patients, the practical reality is that you will need to confirm the current legal and clinic-specific position with the treating clinic and, if you want certainty, with a Thai lawyer who specializes in assisted reproduction. Do not assume that because a clinic advertises PGT-A it also offers non-medical sex selection.

    Questions to ask a clinic in Thailand

    Before you commit to treatment, ask the clinic directly about its policy and process. The answers will help you decide whether to proceed and how to plan.

    • Does your clinic offer PGT-A, and does the report include sex chromosomes?
    • If sex is reported, can patients request transfer of a specific sex for non-medical reasons?
    • What are your clinic’s written policies on family balancing and sex selection?
    • Are there any legal restrictions in Thailand that affect my situation as an international patient?
    • What counseling do you provide before PGT-A and before any sex-based embryo transfer?
    • What are the costs of PGT-A, embryo storage, and transfer, and what do those fees include?
    • What documents do I need to provide, and do any of them need translation or notarization?
    • What are the success rates for my age group, and how do you define success?
    • What happens to embryos that are not transferred?
    • Can you connect me with a legal professional who can advise on Thai law?

    Ethical considerations for your decision

    Choosing to use PGT-A for gender selection is a personal decision that may involve ethical, cultural, and family considerations. Some questions to reflect on include:

    • Why do I want to select the sex of my child? Is it for family balancing, cultural reasons, or other motivations?
    • How would I feel if the transfer did not result in a pregnancy, or if the selected embryo did not implant?
    • Am I comfortable with the idea of discarding or donating embryos that are not the desired sex?
    • Have I considered the child’s perspective and the message that sex selection might send?
    • Do I have accurate information about the legal and clinic-specific rules in Thailand?

    There are no universally right or wrong answers. A counselor or ethics consultant can help you explore these questions without pushing you toward a particular choice.

    Alternatives and limitations

    PGT-A is not the only option, and it is not necessary for everyone. Alternatives include:

    • Proceeding with IVF without PGT-A and accepting the natural sex ratio.
    • Using PGT-M or PGT-SR if you have a medical reason to avoid a sex-linked or chromosomal condition.
    • Choosing not to select sex and focusing on embryo quality and transfer timing.
    • Considering adoption or other family-building paths.

    Limitations of PGT-A include the possibility of false results, the fact that not all embryos are suitable for biopsy, and the reality that a normal result does not guarantee a healthy baby. PGT-A also adds cost and complexity to an IVF cycle. For some patients, the additional information is valuable; for others, it may not change the outcome.

    Planning your next steps

    If you are considering PGT-A gender selection in Thailand, a careful approach can help you avoid surprises.

    1. Clarify your own reasons and ethical comfort level.
    2. Research clinics that offer PGT-A and ask about their sex selection policy in writing.
    3. Confirm the legal context with a qualified Thai legal professional if you need certainty.
    4. Ask about costs, timelines, and what is included in the quoted price.
    5. Discuss the risks and limitations of PGT-A with a reproductive endocrinologist.
    6. Consider speaking with a counselor about the emotional and family implications.
    7. Prepare your travel and documentation based on what the clinic tells you, not on general internet claims.

    Frequently asked questions

    Is PGT-A gender selection legal in Thailand?

    The legal status of non-medical sex selection in Thailand is not straightforward and may depend on clinic policy, professional guidelines, and the specific circumstances. This guide cannot provide a legal conclusion. You should confirm the current position directly with the treating clinic and, if you need certainty, with a qualified Thai legal professional.

    Can PGT-A tell the sex of an embryo?

    PGT-A examines chromosomes, including the sex chromosomes, so it can sometimes reveal the sex of an embryo. However, whether that information is reported and whether it can be used for gender selection depends on the laboratory and the clinic's policy. Not all clinics offer sex selection for non-medical reasons.

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

    PGT-A screens for an abnormal number of chromosomes (aneuploidy). PGT-M looks for a specific inherited genetic condition. PGT-SR looks for structural chromosome rearrangements. Each test has different purposes and limitations, and none guarantees a successful pregnancy or a healthy child.

    What ethical issues should I consider before choosing gender selection?

    Ethical considerations include your reasons for selecting sex, how you feel about discarding or donating embryos of the non-desired sex, the potential impact on the child and family, and broader concerns about gender discrimination. A counselor can help you explore these questions without judgment.

    What should I ask a clinic in Thailand about PGT-A and gender selection?

    Ask whether the clinic offers PGT-A, whether sex is reported, whether non-medical sex selection is permitted, what counseling is provided, what the costs include, what documents are required, and what the clinic's success rates mean for your age group. Also ask for written policies and, if needed, a referral to a Thai legal professional.

  • PGT-A Sample Shipping from Thailand: What Patients Should Ask Before Biopsy Transport

    If your embryos are biopsied in Thailand but the genetic testing happens in another country, the biopsy samples must travel between laboratories. This is often called PGT-A sample shipping. The logistics matter because a sample that is delayed, mishandled or poorly documented may not give a usable result. You do not need to become a shipping expert, but you should know which questions to ask before biopsy day. This guide explains the main steps, the categories of information to confirm, and the practical checks that help you stay informed without relying on assumptions.

    At a glance

    • PGT-A looks at chromosome number in biopsied embryo cells; it does not guarantee a pregnancy or a healthy child.
    • Cross-border sample shipping involves the IVF clinic, the testing laboratory and often a courier or logistics provider.
    • Timing, temperature, packaging, documentation and communication are the main categories to confirm.
    • Ask who is responsible at each step and how you will be told if something changes.
    • Keep your questions in writing so you have a record of what was agreed.

    What PGT-A is and why shipping is part of the plan

    Preimplantation genetic testing for aneuploidy (PGT-A) is a laboratory test performed on a small number of cells removed from an embryo during IVF. The test estimates whether the embryo has the expected number of chromosomes. It is one type of preimplantation genetic testing; PGT-M looks at a specific inherited condition, and PGT-SR looks at chromosome rearrangements. Each has different purposes and limitations.

    When the biopsy is performed in Thailand and the testing laboratory is in another country, the sample must be transported across borders. That adds logistics to the treatment plan. The goal is to keep the sample stable and identifiable from the moment it is collected until the laboratory reports a result. Your clinic and the testing laboratory should have a agreed process for this. Your role is to understand the process well enough to ask informed questions.

    Who is involved in the shipping chain

    Cross-border sample transport usually involves several parties. The exact arrangements vary, so confirm the details for your own case.

    • IVF clinic in Thailand: performs the biopsy, prepares the sample and may coordinate the handover to a courier.
    • Testing laboratory: receives the sample, processes it and issues the report.
    • Courier or logistics provider: moves the sample between countries under specific conditions.
    • You and your partner: provide consent, confirm identity details and may need to approve or acknowledge shipping arrangements.

    Ask for a simple map of who does what. If no single person is clearly responsible for the handover, that is a gap worth clarifying before biopsy day.

    Timing: when the sample is collected and when it travels

    Biopsy timing is linked to embryo development in the laboratory. The sample is usually taken at a specific stage, and the shipping schedule should be planned around that stage. You do not need to memorise the biology, but you should ask how the clinic and the testing laboratory align their schedules.

    Questions to ask about timing:

    • On which day after fertilisation is the biopsy expected to take place?
    • How soon after biopsy is the sample prepared for transport?
    • Is there a planned shipping day, and what happens if that day changes?
    • How long is the sample expected to be in transit?
    • What is the backup plan if a flight is delayed or a courier misses a collection?
    • Will the embryo be frozen while waiting for the result, and how does that affect the timeline?

    Because transport schedules and laboratory cut-off times can change, treat any specific timing you are given as an estimate to confirm with the clinic and laboratory, not as a fixed promise.

    Transport conditions: what to confirm

    Biopsy samples are delicate. The testing laboratory usually specifies how the sample should be packaged and transported. The IVF clinic should follow those instructions. Ask both sides to confirm the same requirements.

    Categories to confirm:

    • Packaging: what type of container, vial or tube is used, and how it is sealed and labelled.
    • Temperature: whether the sample travels at room temperature, refrigerated or frozen, and how that temperature is maintained.
    • Documentation: what paperwork, labels or identifiers travel with the sample.
    • Chain of custody: how the sample is tracked from clinic to laboratory, and who signs for it at each handover.
    • Customs and import rules: what the courier or laboratory needs to clear the sample through the destination country.
    • Insurance or contingency: what happens if the sample is delayed, damaged or lost.

    You do not need to arrange these details yourself, but you should know who is responsible for each one. If the answer is unclear, ask for it in writing.

    Communication between the two laboratories

    Good communication reduces the risk of confusion. The IVF clinic and the testing laboratory should agree on how they will share information before, during and after shipping.

    Ask about:

    • Who is the main contact at each laboratory?
    • How will they confirm that the sample has been collected and shipped?
    • How will they confirm that the sample has arrived and been accepted for testing?
    • What is the expected turnaround time for the result, and how is that communicated?
    • Who will explain the result to you, and in what language?
    • What happens if the laboratory needs more information or the sample cannot be tested?

    If you are coordinating across languages and time zones, ask whether written summaries will be provided. Keep copies of all messages and documents.

    Checklist: questions to ask before biopsy day

    Use this checklist as a starting point. Add your own questions and record the answers.

    Topic Questions to ask
    Roles Who performs the biopsy? Who prepares the sample? Who arranges shipping? Who receives it?
    Timing When is the biopsy expected? When does the sample ship? How long is transit? What is the backup plan?
    Transport What packaging and temperature are required? How is the sample tracked? What documents travel with it?
    Customs What import or export paperwork is needed? Who prepares it? What happens if clearance is delayed?
    Communication Who contacts whom? How will you be updated? Who explains the result?
    Contingency What if the sample is delayed, damaged or unusable? What are the options then?
    Costs Which shipping, courier, documentation and testing costs are included, and which are separate?

    What can go wrong, and how to stay informed

    Cross-border shipping has several points where delays or problems can occur. Weather, flight schedules, customs checks and courier errors are outside your control. What you can control is how well you understand the plan and how quickly you are told if something changes.

    Ask the clinic and laboratory to tell you:

    • What events would trigger a call or email to you.
    • Who will contact you if the sample is delayed.
    • What options exist if the sample cannot be tested.
    • Whether a repeat biopsy would be possible, and what that would involve.

    Remember that PGT-A is a screening test, not a guarantee. It can provide useful information, but it cannot ensure a pregnancy, a live birth or a child without a genetic condition. Your clinic should explain the limitations and alternatives for your situation.

    Costs and paperwork: what to confirm

    Shipping a biopsy sample across borders usually involves several cost categories. These may include courier fees, packaging materials, documentation, customs clearance, laboratory handling and the genetic test itself. Some clinics bundle these; others list them separately. Because prices and rules vary, ask for a written breakdown of what is included and what is not.

    Paperwork may include consent forms, sample identification documents, import or export permits, and courier waybills. The exact requirements depend on the countries involved and can change. Confirm with your clinic, the testing laboratory and the courier what is needed for your case. Do not rely on general advice from other patients, because rules differ by destination and by laboratory.

    Next steps

    1. Ask your clinic for a written summary of the biopsy and shipping process.
    2. Confirm who is responsible at each step and how you will be contacted.
    3. Request a cost breakdown that separates shipping from testing.
    4. Ask the testing laboratory what it needs from the clinic and from you.
    5. Keep copies of all consent forms, labels and messages.
    6. Review the PGT in Thailand guide and the patient guides for more context.
    7. Check the FAQ for common questions about PGT and logistics.

    If any answer is vague, ask again. A clear process is easier to follow and easier to trust.

    Frequently asked questions

    Can I arrange the shipping of my PGT-A sample myself?

    In most cases, the IVF clinic and the testing laboratory coordinate shipping because the sample must be handled under specific conditions and with correct documentation. You may be asked to provide consent or identity documents, but the clinic and laboratory usually manage the courier and packaging. Ask your clinic who is responsible before biopsy day.

    How long does it take for a biopsy sample to travel from Thailand to another country?

    Transit time depends on the destination, flight schedules, customs clearance and the courier. It is not possible to give a single reliable figure. Ask your clinic and the testing laboratory for an estimate for your specific route, and ask what happens if the sample is delayed.

    What happens if the sample is damaged or cannot be tested?

    If a sample cannot be tested, the laboratory should inform your clinic. Your clinic should then explain the options, which may include discussing whether a repeat biopsy is possible. The exact options depend on your embryos and your treatment plan, so ask your clinic to explain what would happen in your case.

    Does PGT-A guarantee a healthy baby?

    No. PGT-A estimates chromosome number in the biopsied cells, but it cannot guarantee a pregnancy, a live birth or a child without a genetic condition. It is a screening test with limitations. Your clinic should discuss what PGT-A can and cannot tell you, and what alternatives exist.

    What should I ask about communication between the two laboratories?

    Ask who the main contact is at each laboratory, how they will confirm collection, shipping and arrival, how long the result is expected to take, and who will explain the result to you. If you speak a different language from the laboratory, ask whether written summaries will be provided.

  • PGT-A Cost Breakdown in Thailand: How to Read and Compare a Quote

    PGT-A cost in Thailand is rarely a single number. Most quotes combine IVF laboratory work, embryo biopsy, genetic testing per embryo, medication, monitoring, and administrative items. Because clinics package these differently, the only reliable way to compare is a written, itemised quote that states what is included, what is excluded, and how charges change if more embryos are tested or a cycle is repeated. This guide explains the categories to look for and the questions that make quotes comparable.

    At a glance

    • A PGT-A quote usually bundles IVF cycle costs with biopsy and genetic testing, but the boundaries vary by clinic.
    • Per-embryo testing fees are a common variable; ask how many embryos are covered and what happens beyond that number.
    • Medication, pre-treatment testing, storage, and follow-up are frequent exclusions.
    • Ask for a written quote with a validity period and a clear list of inclusions and exclusions.
    • Compare quotes line by line, not by the headline total.

    Why PGT-A quotes are hard to compare

    PGT-A, or preimplantation genetic testing for aneuploidy, is a laboratory step added to an IVF cycle. It involves removing a small number of cells from an embryo and testing them for chromosomal number. The clinical decision to use PGT-A, and how results are used, belongs to the treating clinic and the patient. Cost, however, is often presented in packages that mix several services.

    One clinic may quote a single figure covering IVF, biopsy, and testing up to a set number of embryos. Another may quote IVF separately and charge testing per embryo. A third may include medication while another lists it separately. None of these approaches is automatically better; they simply require different questions. The goal is to reconstruct a like-for-like comparison from written documents.

    Core components of a PGT-A cost quote

    When you receive a quote, check whether each of the following categories is included, excluded, or charged separately. The list is a framework, not a prediction of what any specific clinic will charge.

    Component What it typically covers What to confirm
    IVF cycle Monitoring, egg retrieval, laboratory fertilisation and embryo culture Number of monitoring visits, anaesthesia, and whether a fresh or frozen transfer is included
    Embryo biopsy Laboratory procedure to sample cells from each embryo Whether the fee is per embryo or per cycle, and who performs it
    Genetic testing Laboratory analysis of biopsy samples for chromosomal number Number of embryos covered, reporting method, and turnaround time
    Medication Stimulation and cycle-support drugs Whether included, estimated separately, or purchased outside the clinic
    Pre-treatment testing Blood tests, imaging, and screening required before the cycle Which tests are mandatory, where they can be done, and whether results expire
    Embryo storage Cryopreservation and storage of surplus embryos Free storage period, annual fee after that, and what happens if storage is discontinued
    Follow-up Consultations, results review, and transfer planning Whether included in the package or billed per visit

    Common add-ons and exclusions

    Quotes often look lower because certain items sit outside the package. These are not necessarily hidden fees, but they are easy to overlook when comparing headline numbers.

    • Additional embryos: testing beyond the number included in the package.
    • Repeat or cancelled cycles: whether any portion is refundable or discounted.
    • Frozen embryo transfer: a separate procedure if the first transfer is deferred.
    • Medication adjustments: dose changes during stimulation can alter the medication total.
    • Laboratory extras: techniques such as assisted hatching or sperm selection, if recommended.
    • Administrative items: registration, records, translation, or courier fees.
    • Travel and accommodation: rarely included and highly individual.

    Ask the clinic to mark each item as included, excluded, or conditional. A conditional item is one that depends on your response to treatment, such as the number of embryos available for biopsy.

    Questions to ask before comparing prices

    These questions turn a marketing figure into a comparable quote. Ask them in writing so you can refer back to the answers.

    1. Can you send a written, itemised quote with a validity period?
    2. How many embryos does the quoted testing fee cover, and what is the charge per additional embryo?
    3. Is medication included? If not, can you provide an estimated range and a list of drugs?
    4. Which pre-treatment tests are required, and can any be done in my home country?
    5. What happens to the price if the cycle is cancelled, or if no embryos are suitable for biopsy?
    6. Are storage fees included for the first year? What is the annual fee afterwards?
    7. Does the quote include a fresh transfer, a frozen transfer, or both?
    8. Are there separate charges for consultations, results review, or follow-up?
    9. What is the payment schedule, and which currencies are accepted?
    10. Who is my main contact for billing questions?

    How to build a comparison table

    Once you have written quotes, place them side by side using the same categories. Do not convert currencies using a single day’s rate without noting the date; exchange rates move. Instead, compare the structure first, then the totals.

    • List each component from the table above as a row.
    • Mark included, excluded, or conditional for each clinic.
    • Note any per-embryo or per-cycle assumptions.
    • Add a column for questions you still need answered.
    • Keep the original quotes and any email clarifications together.

    This approach shows whether a lower headline price is genuinely lower or simply excludes items another clinic includes.

    Planning beyond the quote

    Cost is one part of planning. You may also need to consider travel, time away from work, and the number of visits a cycle requires. Ask the clinic how many trips are typically needed and whether monitoring can be shared with a local clinic. These practical points affect the total cost of treatment even when they are not on the invoice.

    For broader context on IVF costs and planning, see our guides on PGT-A cost in Thailand and IVF cost in Thailand. You can also explore patient resources for checklists and questions to bring to consultations. If you would like help organising quotes or understanding next steps, you can contact us.

    Next-step checklist

    • Request written, itemised quotes from each clinic you are considering.
    • Confirm the number of embryos covered by the testing fee.
    • Ask which items are excluded and which are conditional.
    • Check medication, storage, and follow-up charges separately.
    • Note the quote validity period and payment schedule.
    • Keep all answers in one document for side-by-side comparison.
    • Ask the clinic to clarify anything that is not in writing.

    No article can tell you what a specific clinic will charge, because prices depend on the clinic, the treatment plan, and your individual response. A written quote is the only reliable basis for comparison.

    Frequently asked questions

    What should a PGT-A cost quote in Thailand include?

    A useful quote separates the IVF cycle, embryo biopsy, genetic testing, medication, pre-treatment testing, storage, and follow-up. It should state which items are included, which are excluded, and which depend on your response to treatment, such as the number of embryos available for testing.

    Why do PGT-A prices vary so much between clinics?

    Clinics package services differently. Some bundle IVF, biopsy, and testing up to a set number of embryos; others charge testing per embryo or list medication separately. Variation also reflects different laboratory arrangements and administrative practices. Comparing itemised quotes is more reliable than comparing headline totals.

    Are there hidden fees in PGT-A quotes?

    Not necessarily hidden, but some items are commonly excluded from package prices. These can include testing beyond the included number of embryos, repeat or cancelled cycles, frozen embryo transfer, medication adjustments, storage after an initial period, and administrative charges. Ask for a written list of inclusions and exclusions.

    How can I compare PGT-A quotes from different clinics?

    Use the same categories for each quote, mark each item as included, excluded, or conditional, and note any per-embryo assumptions. Keep the written quotes and any email clarifications together. This makes it easier to see whether a lower total reflects a genuine difference or simply fewer included services.

    Can I get a fixed PGT-A price before treatment?

    Some clinics offer package prices, but many costs depend on your treatment plan and response, such as the number of embryos tested or medication dose. Ask whether the quote is fixed, conditional, or an estimate, and request a written validity period.
