  • How to Read Your PGT Results from a Thailand Lab

    Understanding PGT Results

    Preimplantation Genetic Testing (PGT) is a technique used during IVF to screen embryos for genetic abnormalities before transfer. Results from a Thailand lab typically fall into categories such as euploid, aneuploid, mosaic, or inconclusive. This guide explains these terms and what they mean for your next steps.

    Types of PGT

    PGT-A (Aneuploidy Screening)

    PGT-A checks embryos for the correct number of chromosomes. A normal result is called euploid, meaning the embryo has the expected 46 chromosomes. An abnormal result is aneuploid, indicating missing or extra chromosomes. Some embryos show a mix of normal and abnormal cells, known as mosaic. Occasionally, the lab cannot give a clear result, labeled inconclusive.

    PGT-M (Monogenic Disorders)

    PGT-M screens for specific single-gene disorders such as cystic fibrosis or thalassemia. Results indicate whether the embryo carries the disease-causing mutation, is unaffected, or is a carrier (if relevant).

    PGT-SR (Structural Rearrangements)

    PGT-SR detects chromosomal structural changes like translocations or inversions. Results show whether the embryo has a balanced or unbalanced rearrangement.

    Interpreting Your Results

    Euploid

    A euploid embryo has the correct number of chromosomes and is considered chromosomally normal. For PGT-A, this is generally the preferred category for transfer, as it has the highest chance of implantation and a healthy pregnancy. However, euploid does not guarantee a successful pregnancy or a healthy baby.

    Aneuploid

    An aneuploid embryo has an abnormal chromosome count, such as trisomy (extra chromosome) or monosomy (missing chromosome). Most aneuploid embryos will not implant or will miscarry. Some may result in a child with a condition like Down syndrome. Transfer of aneuploid embryos is generally not recommended, but you should discuss all options with your doctor.

    Mosaic

    A mosaic embryo contains both normal and abnormal cells. The proportion of abnormal cells is reported as a percentage (e.g., 20% mosaic). Mosaic embryos may have reduced implantation potential and a small risk of a chromosomal condition. Some clinics consider transfer of low-level mosaics (<20-30%) after counseling. The decision is complex and should involve a genetic counselor.

    Inconclusive

    An inconclusive result means the lab could not determine the embryo’s chromosomal status due to technical issues, such as failed amplification or poor DNA quality. Your doctor may recommend retesting or consider the embryo for transfer after discussing risks.

    What Each Result Means for Transfer Decisions

    • Euploid: Highest priority for transfer. Discuss with your doctor.
    • Aneuploid: Typically not transferred. Confirm with your clinic’s policy.
    • Mosaic: May be considered for transfer if no euploid embryos are available. Requires genetic counseling.
    • Inconclusive: Options include retesting or transfer after counseling. Not all labs offer retesting.

    Limitations of PGT

    PGT is a screening tool, not a diagnostic test. It cannot detect all genetic conditions, and a normal result does not guarantee a healthy baby. Embryo biopsy carries a small risk of damage. PGT is not recommended for everyone; your doctor can help determine if it is appropriate for your situation.

    Alternatives to PGT

    If PGT is not suitable or you prefer not to test, alternatives include prenatal testing (chorionic villus sampling or amniocentesis) during pregnancy, or using donor eggs or sperm. Discuss these options with your fertility specialist.

    Questions to Ask Your Clinic

    • What type of PGT was performed (PGT-A, PGT-M, PGT-SR)?
    • How are mosaic embryos classified and what are your transfer criteria?
    • What is the lab’s inconclusive rate?
    • Do you offer retesting for inconclusive embryos?
    • What genetic counseling is available?

    Frequently asked questions

    What does euploid mean in PGT results?

    Euploid means the embryo has the correct number of chromosomes (46) and is considered chromosomally normal. It is the preferred category for transfer.

    Can a mosaic embryo be transferred?

    Yes, some clinics may transfer mosaic embryos, especially if no euploid embryos are available. The decision involves genetic counseling and depends on the level of mosaicism.

    What should I do if my PGT result is inconclusive?

    Discuss with your doctor whether retesting is possible or if transfer of the embryo is an option after counseling. Not all labs offer retesting.

  • IVF in Thailand for Women Over 38: What to Expect with PGT

    What to Expect from IVF with PGT in Thailand When You Are Over 38

    If you are over 38 and considering IVF in Thailand, you may be wondering how preimplantation genetic testing (PGT) fits into your journey. PGT can help identify embryos with the correct number of chromosomes (euploid) before transfer, which is especially relevant as the risk of chromosomal abnormalities (aneuploidy) increases with age. This article explains what you can generally expect, the important distinctions to understand, and the questions you should ask your clinic.

    Age-Related Aneuploidy and Euploid Embryo Rates

    As women age, a higher proportion of eggs and resulting embryos are likely to have an abnormal number of chromosomes. This is a natural biological process. For women over 38, the chance of producing a chromosomally normal (euploid) embryo per egg retrieved is lower compared to younger women. However, individual results vary widely. PGT can help identify which embryos are euploid, potentially increasing the chance of a successful pregnancy per transfer and reducing the risk of miscarriage due to chromosomal abnormalities.

    It is important to have realistic expectations. Not every cycle will produce a euploid embryo, and multiple cycles may be needed. Your clinic can provide personalized estimates based on your ovarian reserve, age, and other factors.

    Key Distinctions: PGT-A vs. PGT-M vs. PGT-SR

    PGT has different subtypes. For older women, the most common is PGT for aneuploidy (PGT-A), which screens for extra or missing chromosomes. PGT-M is for single-gene disorders, and PGT-SR is for structural rearrangements. Discuss with your clinic which type is appropriate for your situation.

    Cycle Planning Considerations

    IVF with PGT in Thailand typically involves the following steps:

    • Ovarian stimulation and egg retrieval
    • Fertilization (usually via ICSI)
    • Embryo culture to blastocyst stage (day 5-6)
    • Biopsy of a few cells from the trophectoderm (future placenta)
    • Vitrification (freezing) of biopsied embryos
    • Genetic analysis (results may take days to weeks)
    • Frozen embryo transfer (FET) of a euploid embryo in a subsequent cycle

    Because PGT requires freezing embryos, you will likely have a delay between retrieval and transfer. Plan for at least two menstrual cycles for a complete PGT cycle.

    Uncertainties and Variables

    No test can guarantee a healthy baby. PGT reduces but does not eliminate the risk of miscarriage or chromosomal conditions. Embryos can be mosaic (a mix of normal and abnormal cells), and interpretation of results can be complex. Additionally, not all embryos survive the biopsy and freezing process. Your clinic should explain the limitations and success rates based on their own data.

    Questions to Ask Your Clinic

    Before proceeding, consider asking:

    • What is your experience with PGT for women over 38?
    • What are the estimated euploid rates for my age group?
    • How many eggs or blastocysts should I aim for to have a reasonable chance of at least one euploid embryo?
    • What is the turnaround time for PGT results?
    • What are the costs for PGT, and are there any package options?
    • How do you handle mosaic embryos?
    • What is your live birth rate per euploid embryo transfer for women over 38?

    Frequently asked questions

    What is the chance of a euploid embryo for a woman over 38?

    The chance varies by individual age and ovarian reserve. Generally, the proportion of euploid embryos declines with age. Your clinic can provide estimates based on your specific situation.

    Does PGT improve the chance of live birth for older women?

    PGT can help select euploid embryos for transfer, which may reduce miscarriage risk and improve per-transfer success rates. However, it does not guarantee live birth, and the overall chance depends on having at least one euploid embryo.

    How long does a PGT cycle take in Thailand?

    A full cycle with PGT typically spans two menstrual cycles: one for egg retrieval and embryo biopsy, and another for frozen embryo transfer after results are available.

  • What Happens During a PGT Biopsy in Thailand? A Step-by-Step Guide

    Understanding PGT Biopsy in Thailand

    Preimplantation Genetic Testing (PGT) is a procedure used during IVF to screen embryos for genetic abnormalities before transfer. The biopsy is a critical step where a few cells are removed from the embryo for analysis. For international patients considering PGT in Thailand, understanding the biopsy process can help ease anxiety and prepare for the journey.

    This guide explains the step-by-step process of a trophectoderm biopsy on day 5 or 6 blastocysts, addresses common concerns about embryo safety, and outlines what you need to confirm with your treating clinic.

    What Is a Trophectoderm Biopsy?

    A trophectoderm biopsy is performed on embryos that have developed to the blastocyst stage, typically by day 5 or 6 after fertilization. At this stage, the embryo has differentiated into two cell types:

    • Inner cell mass (ICM): Develops into the fetus.
    • Trophectoderm (TE): Forms the placenta and other supporting tissues.

    During the biopsy, a few cells are gently removed from the trophectoderm layer. This approach is preferred because it does not disturb the inner cell mass, which will become the baby. The removed cells are then sent for genetic analysis.

    Step-by-Step Process of PGT Biopsy in Thailand

    1. Embryo Development to Blastocyst

    After egg retrieval and fertilization, embryos are cultured in the laboratory for 5–6 days. Only embryos that reach the blastocyst stage are considered for biopsy. The embryologist assesses the quality and expansion of each blastocyst.

    2. Preparation for Biopsy

    On the day of biopsy, the blastocyst is held in place using a specialized holding pipette. A laser or a thin glass needle is used to create a small opening in the outer shell of the embryo (the zona pellucida). This step is called hatching or zona drilling.

    3. Cell Removal

    Through the opening, the embryologist gently aspirates 5–10 trophectoderm cells using a biopsy pipette. The cells are carefully separated from the embryo, often with the aid of a laser to ensure a clean cut. The entire process takes only a few minutes.

    4. Embryo Vitrification

    After biopsy, the embryo is immediately frozen (vitrified) to preserve its viability. Vitrification is a rapid freezing technique that prevents ice crystal formation, which can damage cells. The embryo remains frozen while the genetic analysis is performed.

    5. Genetic Analysis

    The biopsied cells are sent to a genetics laboratory for testing. Depending on the type of PGT, the analysis may screen for:

    • PGT-A: Aneuploidy (abnormal number of chromosomes).
    • PGT-M: Monogenic disorders (single-gene diseases).
    • PGT-SR: Structural rearrangements (e.g., translocations).

    Results typically take 1–2 weeks, though this can vary by clinic and laboratory.

    6. Embryo Transfer

    Once results are available, a frozen embryo transfer (FET) is scheduled in a subsequent menstrual cycle. Only genetically normal (euploid) embryos are selected for transfer.

    Is the Biopsy Safe for the Embryo?

    Embryo safety is a top concern for patients. Trophectoderm biopsy is considered safe when performed by experienced embryologists. Key safety points include:

    • Cell selection: Only trophectoderm cells are removed, leaving the inner cell mass intact.
    • Minimal cell loss: The number of cells taken is small relative to the total cell count of a blastocyst (typically 100–200 cells).
    • Vitrification: Freezing after biopsy has been shown to have high survival rates.

    However, no medical procedure is without risk. Some studies suggest a slight reduction in implantation rates after biopsy, but the evidence is not conclusive. Discuss the risks and benefits with your fertility specialist.

    What to Expect as an International Patient in Thailand

    Travel and Timeline Planning

    PGT adds time to the IVF cycle. A typical timeline might include:

    • Ovarian stimulation and egg retrieval: 10–14 days in Thailand.
    • Embryo culture and biopsy: 5–6 days after retrieval.
    • Genetic testing: 1–2 weeks (you may return home during this period).
    • Frozen embryo transfer: Requires a separate trip of about 1–2 weeks.

    Confirm the exact timeline with your clinic, as it can vary based on your treatment plan and the laboratory’s workload.

    Clinic Selection

    When choosing a clinic in Thailand for PGT, consider:

    • Embryology expertise: Ask about the embryologists’ experience with trophectoderm biopsy.
    • Genetic laboratory: Some clinics have in-house labs; others send samples to partner labs. Inquire about accreditation and turnaround times.
    • Success rates: Request clinic-specific data for PGT cycles, but remember that success rates depend on many factors.

    Legal and Regulatory Considerations

    Thailand has regulations governing PGT. For example, PGT for sex selection is not permitted. Confirm with your clinic which genetic tests are legally available and what documentation is required.

    Questions to Ask Your Clinic

    To prepare for your PGT biopsy in Thailand, ask your clinic:

    • What is the embryologist’s experience with trophectoderm biopsy?
    • How many cells are typically removed, and what is the embryo survival rate after biopsy and vitrification?
    • Which genetic tests are offered, and what is the turnaround time for results?
    • What is the cost of PGT, and does it include the biopsy, genetic analysis, and vitrification?
    • What is the policy on embryo freezing and storage?

    Conclusion

    The PGT biopsy in Thailand is a precise, minimally invasive procedure performed on day 5 or 6 blastocysts. By understanding the steps and asking the right questions, you can approach the process with confidence. Always consult with your treating clinic for personalized advice and confirm all details before making travel arrangements.

    Frequently asked questions

    How many cells are removed during a PGT biopsy?

    Typically, 5–10 trophectoderm cells are removed from a day 5 or 6 blastocyst. The exact number may vary by clinic and embryo quality.

    Does the biopsy hurt the embryo?

    The biopsy is performed under a microscope using specialized tools. The embryo does not have pain receptors, so it does not feel pain. The procedure is designed to minimize stress on the embryo.

    How long does the biopsy take?

    The actual biopsy procedure usually takes only a few minutes per embryo. However, the entire process including preparation and vitrification may take longer.

    Can the embryo be damaged during biopsy?

    When performed by an experienced embryologist, the risk of damage is low. The trophectoderm cells are taken from the outer layer, leaving the inner cell mass intact. Vitrification after biopsy has high survival rates.

    Do I need to stay in Thailand during genetic testing?

    No, you can return home while the genetic analysis is performed. Results typically take 1–2 weeks. You will need to return for a frozen embryo transfer in a subsequent cycle.

  • Embryo Freezing and Storage Costs in Thailand: A Guide for International Patients

    Understanding Embryo Freezing and Storage Costs

    For patients considering multiple IVF cycles or preserving embryos for future family building, embryo freezing (cryopreservation) and storage are important steps. Costs in Thailand can vary significantly between clinics and depend on several factors. This guide outlines the typical cost components, what to ask when comparing quotes, and considerations for long-term storage or shipping embryos abroad.

    Cost Components

    Embryo freezing and storage fees generally include:

    • Initial cryopreservation fee: A one-time charge for the vitrification process, which may include the cost of cryoprotectants and the embryologist’s time.
    • Annual storage fee: A yearly charge for maintaining embryos in liquid nitrogen tanks. Some clinics offer discounts for multi-year prepayment.
    • Administrative fees: Costs for documentation, record-keeping, and possibly a release fee if embryos are transferred to another clinic or shipped abroad.

    Some clinics bundle the first year of storage with the IVF cycle fee, while others charge separately. Always request a detailed breakdown.

    Annual Storage Fees and Long-Term Options

    Annual storage fees are typically quoted per year. When comparing clinics, ask:

    • Is the first year included in the IVF package?
    • What is the annual storage fee for subsequent years?
    • Are there discounts for paying multiple years in advance?
    • Is there a maximum storage duration? (Some clinics may have policies on how long embryos can be stored.)
    • What happens if you miss a payment? (e.g., grace period, disposal policy)

    Long-term storage may involve signing a storage agreement that outlines the clinic’s policies on embryo disposition, including donation, disposal, or transfer.

    Shipping Embryos Abroad

    If you plan to transfer your embryos to another country, additional costs include:

    • Shipping fee: A specialized cryogenic shipping container and courier service for transporting embryos. This is often arranged through a third-party company.
    • Export/import documentation: Fees for preparing and certifying documents required by the destination country’s regulations.
    • Receiving clinic fees: The destination clinic may charge an administrative fee to accept and store the embryos.

    Shipping costs are typically quoted separately and depend on distance, courier, and any customs or legal requirements. Confirm with both the sending and receiving clinics about their specific procedures and fees.

    Questions to Ask When Comparing Quotes

    To make an informed decision, ask each clinic:

    • What is included in the initial cryopreservation fee? (e.g., number of embryos, any additional charges for multiple straws)
    • Are there any hidden fees (e.g., annual price increases, transfer fees within the same clinic)?
    • What is the clinic’s policy on embryo storage duration and disposition?
    • Do you offer a payment plan for long-term storage?
    • What are the procedures and costs for shipping embryos to another country?
    • Can you provide a written estimate that includes all potential charges?

    Additional Considerations for International Patients

    As an international patient, you may also need to factor in:

    • Currency exchange rates: Fees quoted in Thai baht may fluctuate in your home currency.
    • Communication: Ensure the clinic can provide cost information in English and clarify any terms.
    • Legal and regulatory aspects: Some countries have restrictions on embryo export/import. Verify with your home country’s authorities and the Thai clinic.

    For more detailed planning, see our IVF cost guide and patient resources. If you have specific questions, contact us for assistance.

    Frequently asked questions

    What is typically included in the initial embryo freezing fee?

    The initial fee usually covers the vitrification process, including cryoprotectants and embryologist time. Some clinics may include the first year of storage. Always ask for a detailed breakdown.

    Are there discounts for paying multiple years of storage upfront?

    Some clinics offer discounts for prepaying several years of storage. Inquire directly with the clinic about any long-term payment options.

    What happens if I stop paying the annual storage fee?

    Policies vary. Some clinics have a grace period, while others may dispose of embryos after a certain period of non-payment. Review the storage agreement carefully.

    How much does it cost to ship embryos from Thailand to another country?

    Shipping costs depend on the courier, distance, and documentation requirements. Obtain quotes from both the sending clinic and a specialized cryogenic shipping company.

    Can I store embryos indefinitely in Thailand?

    Storage duration policies vary by clinic. Some may have maximum storage periods, while others allow indefinite storage as long as fees are paid. Confirm with the clinic.

  • How to Choose Between PGT-A and PGT-M for IVF in Thailand

    What Are PGT-A and PGT-M?

    Preimplantation genetic testing (PGT) is performed on embryos created through in vitro fertilization (IVF) before transfer to the uterus. Two common types are PGT-A and PGT-M.

    • PGT-A (Preimplantation Genetic Testing for Aneuploidy) screens embryos for abnormal numbers of chromosomes (aneuploidy). It helps identify embryos with the correct chromosome count (euploid), which may have a higher chance of implantation and lower risk of miscarriage due to chromosomal errors.
    • PGT-M (Preimplantation Genetic Testing for Monogenic Disorders) detects specific single-gene disorders, such as cystic fibrosis, sickle cell disease, or Huntington’s disease. It is used when one or both parents carry a known genetic mutation.

    A third type, PGT-SR (Preimplantation Genetic Testing for Structural Rearrangements), identifies embryos with balanced or unbalanced chromosomal rearrangements, such as translocations. This article focuses on PGT-A and PGT-M, as they are the most commonly discussed.

    Key Differences in Purpose and Technique

    Aspect PGT-A PGT-M
    Purpose Screen for chromosome number abnormalities Detect specific single-gene disorders
    Who needs it Often recommended for advanced maternal age, recurrent miscarriage, repeated implantation failure, or severe male factor infertility; also used for any patient wanting to reduce aneuploidy risk Couples known to carry a genetic mutation for a serious inherited condition
    Technique Biopsy of 5–10 cells from the trophectoderm (future placenta) on day 5/6; analyzed by next-generation sequencing (NGS) or array comparative genomic hybridization (aCGH) Same biopsy method; then uses polymerase chain reaction (PCR) or other mutation-specific methods to test for the known mutation
    Result Euploid (normal), aneuploid (abnormal), or mosaic (mixed cell lines) Affected, unaffected (carrier or non-carrier), or inconclusive
    Limitations Cannot detect all genetic disorders; mosaicism can complicate interpretation; does not guarantee pregnancy or live birth Requires prior knowledge of the specific mutation; test must be custom-developed for each family; may have technical limitations

    When Are Both PGT-A and PGT-M Needed?

    In some cases, a couple may benefit from both tests. For example:

    • A woman of advanced maternal age who also carries a BRCA1 mutation may want PGT-A to reduce aneuploidy risk and PGT-M to select embryos without the mutation.
    • A couple with a history of recurrent miscarriage and a known single-gene disorder may use PGT-A to identify chromosomally normal embryos and PGT-M to avoid the inherited condition.

    When both tests are performed, the embryo biopsy is the same, but the genetic analysis includes both aneuploidy screening and mutation detection. This is often called combined PGT or PGT-A+PGT-M.

    Example Scenarios

    Scenario 1: Advanced Maternal Age

    A 40-year-old woman with no known genetic disorders may choose PGT-A to select euploid embryos, potentially improving implantation rates and reducing miscarriage risk. PGT-M is not needed.

    Scenario 2: Known Genetic Mutation

    A couple where both partners are carriers of cystic fibrosis may opt for PGT-M to identify embryos that are unaffected. If the female partner is under 35 with no fertility issues, PGT-A may not be necessary, though some clinics offer it as an optional add-on.

    Scenario 3: Both Indications

    A 38-year-old woman who carries a mutation for Huntington’s disease may choose both PGT-A and PGT-M to maximize the chance of a healthy pregnancy.

    How to Decide: Questions to Discuss With Your Doctor

    Choosing between PGT-A and PGT-M—or deciding to use both—requires careful counseling. Consider asking your fertility specialist and genetic counselor:

    • What is my risk of having an embryo with a chromosomal abnormality or a specific genetic disorder?
    • Does my age, medical history, or family history suggest a benefit from PGT-A?
    • Have I or my partner been tested for carrier status of common genetic conditions?
    • What are the success rates and limitations of each test at the clinic I am considering?
    • How will the results affect embryo transfer decisions?
    • What are the costs and timelines for each test?

    Remember that PGT does not guarantee a pregnancy or a healthy baby. It is a screening tool that can reduce certain risks but cannot eliminate all possibilities of genetic or chromosomal conditions.

    Alternatives and Additional Considerations

    For patients who do not wish to undergo PGT, alternatives include:

    • Prenatal testing (chorionic villus sampling or amniocentesis) during pregnancy to diagnose chromosomal or genetic conditions.
    • Non-invasive prenatal testing (NIPT) for common aneuploidies, though it is a screening test, not diagnostic.
    • Donor eggs or sperm to avoid passing on genetic disorders.
    • Natural conception with or without carrier screening and prenatal diagnosis.

    Each option has its own benefits, risks, and limitations. A genetic counselor can help you weigh these choices based on your personal values and medical situation.

    Next Steps

    If you are considering IVF with PGT in Thailand, start by consulting a fertility clinic that offers comprehensive genetic testing services. Ask about their experience with PGT-A and PGT-M, the laboratory they use, and the counseling support available. For more information, explore our PGT in Thailand overview, guides, and FAQ.

    Frequently asked questions

    Can PGT-A detect all genetic disorders?

    No, PGT-A only screens for abnormal numbers of chromosomes. It does not detect single-gene disorders or structural rearrangements. For specific genetic conditions, PGT-M or PGT-SR is required.

    Is PGT-M always necessary if I am a carrier of a genetic mutation?

    Not necessarily. If the condition is recessive and your partner is not a carrier, the risk of an affected child is low. However, if both partners are carriers, or if you have an autosomal dominant condition, PGT-M may be recommended. Discuss your specific situation with a genetic counselor.

    Can PGT-A and PGT-M be done together?

    Yes, many clinics offer combined PGT (PGT-A+PGT-M) using the same embryo biopsy. This allows screening for both chromosomal abnormalities and a specific genetic mutation.

    Does PGT guarantee a healthy baby?

    No. PGT reduces the risk of transferring embryos with certain chromosomal or genetic abnormalities, but it cannot guarantee a pregnancy, live birth, or a child free from all health conditions. Some abnormalities may not be detectable, and there is always a small risk of misdiagnosis.

  • Thailand IVF Success Rates by Age Group for PGT Patients: A Hospital Comparison

    Understanding IVF Success Rates by Age with PGT

    When considering IVF with preimplantation genetic testing (PGT), age is one of the most important factors influencing success. As women age, the number and quality of eggs decline, which affects embryo development and the likelihood of a healthy pregnancy. PGT can help identify chromosomally normal embryos, but it cannot overcome the biological limits of egg quality.

    This article provides a general overview of IVF success rates by age group based on published data, and compares several fertility centers in Bangkok that offer PGT. The goal is to help you ask the right questions and make an informed decision. No clinic-specific success rates are provided here; you must verify current data directly with each provider.

    General IVF Success Rates by Age Group

    According to data from national registries and published studies, IVF success rates (live birth per embryo transfer) generally follow these trends:

    • Under 35 years: 40–50% live birth rate per transfer
    • 35–37 years: 30–40%
    • 38–40 years: 20–30%
    • 41–42 years: 10–20%
    • Over 42 years: less than 10%

    These are broad ranges and do not account for individual factors such as ovarian reserve, sperm quality, or the use of donor eggs. PGT may improve the chance of a successful pregnancy by selecting euploid embryos, but the overall success rate still depends on the number of chromosomally normal embryos available, which decreases with age.

    How PGT Affects Success Rates by Age

    PGT-A (aneuploidy screening) can increase the per-transfer success rate because only euploid embryos are transferred. However, the cumulative success rate per cycle may be lower for older women because fewer embryos are likely to be euploid. For example:

    • Women under 35 may have 50–70% of embryos euploid
    • Women 38–40 may have 30–50% euploid
    • Women over 42 may have less than 20% euploid

    This means that older women may need multiple cycles to obtain a euploid embryo. PGT is not a guarantee of pregnancy, but it can reduce the risk of miscarriage and failed implantation due to chromosomal abnormalities.

    Key Questions to Ask Each Clinic

    When evaluating clinics for IVF with PGT, consider asking:

    • What is your live birth rate per embryo transfer for my age group?
    • How many PGT cycles do you perform annually?
    • What is your embryo biopsy technique and lab accreditation?
    • Do you offer genetic counseling?
    • What is the cost of a single cycle including PGT?
    • What is your policy on multiple cycles or refund programs?

    Factors That Influence Success Beyond Age

    Success rates are not solely determined by age. Other factors include:

    • Ovarian reserve (AMH, FSH, antral follicle count)
    • Sperm quality and DNA fragmentation
    • Uterine health (fibroids, polyps, endometriosis)
    • Lifestyle factors (BMI, smoking, stress)
    • Clinic laboratory standards and embryologist expertise

    PGT can help select the best embryo, but it cannot compensate for poor egg or sperm quality. A thorough evaluation by a fertility specialist is essential.

    Conclusion

    IVF success rates decline with age, but PGT can improve per-transfer outcomes by selecting chromosomally normal embryos. When choosing a clinic in Thailand, verify current success data, lab standards, and costs directly. Use this comparison as a starting point for your research.

    Frequently asked questions

    What is the average IVF success rate for women under 35 using PGT?

    For women under 35, IVF with PGT typically results in a live birth rate of 40–50% per embryo transfer. PGT can increase the per-transfer rate by selecting euploid embryos, but the overall success depends on the number of healthy embryos available.

    Does PGT improve success rates for women over 40?

    PGT can improve the per-transfer success rate for women over 40 by reducing the chance of transferring an abnormal embryo. However, the cumulative success per cycle is lower because fewer embryos are likely to be euploid. Multiple cycles may be needed.

    How do Thailand IVF success rates compare to other countries?

    Thailand IVF success rates are generally comparable to international standards, but clinic-specific data should be verified directly. Factors like lab standards, patient selection, and reporting methods can affect comparisons.

    What is the cost of IVF with PGT in Thailand?

    Costs vary widely by clinic and treatment plan. For example, Deep & Harmonicare IVF Center (DHC) offers a basic single-cycle medical package at THB 490,000 (June 2026 reference price), but final costs depend on medications, testing, storage, and additional procedures. Always request a detailed written quotation.

    Which Bangkok fertility centers offer PGT?

    Several Bangkok centers offer PGT, including Deep & Harmonicare IVF Center (DHC), Bumrungrad International Hospital, Gift Fertility Clinic, Intrarat Hospital, PMG Hospital, and Prime Fertility Clinic. Confirm current services directly with each provider.

  • How Many Embryos Should I Test with PGT in Thailand?

    How Many Embryos Should You Test?

    There is no single answer that fits every patient. The number of embryos you choose to biopsy for preimplantation genetic testing (PGT) depends on your specific goals, the number of embryos you have, your budget, and your clinic’s recommendations. This article helps you understand the trade-offs so you can make an informed decision with your doctor.

    Testing All Embryos vs. Selecting Top-Quality

    Testing All Available Embryos

    Some patients choose to biopsy every embryo that reaches the blastocyst stage (typically day 5 or 6). The main advantage is that you get complete genetic information on all embryos, which can help you prioritize transfers and avoid transferring an embryo with a chromosomal abnormality. However, this approach costs more (PGT adds a fee per embryo) and may reveal results that lead to discarding embryos that might have self-corrected or resulted in a healthy baby if transferred untested.

    Selecting Top-Quality Embryos for Testing

    Other patients opt to test only the highest-grade embryos based on morphology (appearance under the microscope). The rationale is that top-quality embryos are more likely to be chromosomally normal, so testing them may give you a good chance of finding a transferable embryo while saving money. The downside is that you might miss a normal embryo that looks lower grade, or you might test a top-quality embryo that turns out to be abnormal, leaving you with fewer options.

    Mosaic Embryo Considerations

    PGT can identify mosaic embryos—those with a mix of normal and abnormal cells. Mosaic embryos may still have the potential to develop into a healthy baby, but the risk of chromosomal issues is higher than with a fully normal embryo. If you test all embryos, you may discover mosaicism that you would not have known about otherwise. This can complicate decision-making: some clinics recommend transferring mosaic embryos only if no normal embryos are available, while others have specific guidelines. Discuss your clinic’s policy on mosaic embryo transfer and whether they offer additional testing (like PGT-A with next-generation sequencing) to better characterize mosaicism.

    Cost-Benefit Analysis

    PGT adds a significant cost to IVF. Testing more embryos increases the total expense, but it may also increase the chance of selecting a euploid (normal) embryo for transfer, potentially reducing the number of failed transfers and the emotional and financial toll of repeated cycles. On the other hand, if you have many embryos, testing all of them might not be necessary if you only need one or two normal embryos for your family-building goals. Consider:

    • Your family size goal: If you want only one child, you may need fewer tested embryos than if you plan for multiple children.
    • Your age and fertility history: Younger patients tend to have higher rates of euploid embryos, so testing fewer may still yield a normal embryo. Older patients or those with recurrent miscarriage may benefit from testing more embryos to avoid transferring abnormal ones.
    • Your budget: Some clinics offer package pricing for PGT that covers a certain number of embryos. Ask about discounts for testing multiple embryos.

    Questions to Ask Your Clinic

    Before deciding, ask your fertility clinic in Thailand:

    • What is the cost per embryo for PGT? Are there package deals?
    • What is your lab’s biopsy success rate? How many cells are taken?
    • How do you report mosaicism? What are your recommendations for mosaic embryo transfer?
    • Do you recommend testing all blastocysts or only those with good morphology? Why?
    • What is the turnaround time for results? How does that affect fresh vs. frozen transfer?
    • Can embryos be re-biopsied if the first test fails?

    Frequently asked questions

    Should I test all my embryos or only the best-looking ones?

    There is no right answer for everyone. Testing all embryos gives you complete genetic information but costs more. Testing only top-quality embryos saves money but may miss a normal lower-grade embryo. Discuss with your doctor based on your embryo count, age, and budget.

    What is a mosaic embryo, and how does it affect my decision?

    A mosaic embryo has both normal and abnormal cells. It may still lead to a healthy baby, but with higher risk. If you test all embryos, you may discover mosaicism, which can complicate transfer decisions. Ask your clinic about their policy on mosaic embryos.

    How many embryos do I need to test to have a good chance of pregnancy?

    The number varies by age and embryo quality. Younger patients may need fewer tested embryos because they have higher rates of normal embryos. Your doctor can estimate based on your specific situation. There is no guaranteed number.

  • Hidden Costs in Thailand IVF Packages: What Budget-Conscious Patients Should Know

    Understanding IVF Package Pricing in Thailand

    When researching IVF in Thailand, many clinics advertise attractive package prices. However, these base packages often cover only the core cycle—medication stimulation, egg retrieval, and embryo transfer. Additional services, which may be essential for your treatment, are frequently billed separately. Understanding these potential extra costs helps you budget accurately and avoid surprises.

    Common Add-Ons and Their Typical Cost Range

    While exact prices vary by clinic and patient needs, the following services are commonly offered as add-ons. Always confirm with your chosen clinic whether these are included or extra.

    • Anesthesia: Egg retrieval is typically performed under sedation or general anesthesia. Some packages include this, but others charge separately.
    • ICSI (Intracytoplasmic Sperm Injection): If male factor infertility is present, ICSI is often recommended. It may be an additional fee.
    • Assisted Hatching: A technique to help the embryo implant, sometimes used for older patients or frozen embryos.
    • Embryo Freezing (Vitrification): Freezing surplus embryos for future use. Initial freezing and annual storage fees may apply.
    • PGT Biopsy Fee: Preimplantation genetic testing requires a biopsy of the embryo. The biopsy itself may be charged separately from the genetic analysis.

    Other Potential Hidden Costs

    Beyond the add-ons above, several other expenses may not be included in a base package:

    • Medication: Fertility drugs can be a significant cost. Some packages include them, others do not.
    • Consultation and Monitoring: Initial consultations, ultrasound scans, and blood tests during the cycle may be extra.
    • Embryo Transfer: The transfer procedure itself might be included, but some clinics charge separately for catheter or ultrasound guidance.
    • Frozen Embryo Transfer (FET): If you use frozen embryos in a later cycle, the FET cycle often has its own fee.
    • Donor Services: If using donor eggs, sperm, or embryos, there are additional costs for donor compensation, screening, and legal fees.
    • Accommodation and Travel: While not clinic fees, your stay in Thailand, flights, and local transport are part of the overall cost.

    How to Compare IVF Packages

    When evaluating quotes from different clinics, follow these steps:

    1. Request a detailed breakdown: Ask for a list of every service included and excluded. Get written confirmation.
    2. Ask about package flexibility: Some clinics offer tiered packages (basic, standard, premium) with different inclusions.

  • IVF Medication Protocols for PGT Cycles in Thailand: A Patient Guide

    Understanding IVF Medication Protocols for PGT

    In vitro fertilization (IVF) with preimplantation genetic testing (PGT) involves controlled ovarian stimulation to produce multiple eggs for biopsy and genetic analysis. The medication protocol is a critical part of this process, influencing the number and quality of eggs retrieved. In Thailand, clinics typically use either antagonist or agonist protocols, tailored to individual patient profiles. This guide explains the general framework of these protocols, how PGT affects medication choices, and what you need to discuss with your treating clinic.

    Common Stimulation Protocols

    Antagonist Protocol

    The antagonist protocol is widely used in Thailand due to its shorter duration and flexibility. It involves daily injections of follicle-stimulating hormone (FSH) to stimulate follicle growth, followed by a GnRH antagonist (e.g., cetrorelix or ganirelix) to prevent premature ovulation. Monitoring via ultrasound and blood tests typically begins around day 5-6 of stimulation and continues every 1-2 days until trigger. The trigger shot (hCG or GnRH agonist) is given when follicles reach an appropriate size, and egg retrieval occurs 34-36 hours later.

    Agonist Protocol

    The agonist (long) protocol uses a GnRH agonist (e.g., leuprolide) to suppress the pituitary gland before stimulation begins. This is followed by FSH injections for 10-14 days. Monitoring frequency is similar to the antagonist protocol. The agonist protocol may be preferred for patients with endometriosis or high ovarian reserve, but it requires a longer lead time.

    How PGT Affects Medication Choices

    PGT requires a sufficient number of eggs and embryos to allow for biopsy and genetic analysis. Therefore, medication protocols aim to maximize the number of mature eggs retrieved. Clinics may adjust FSH doses or add medications like human menopausal gonadotropin (hMG) to improve follicle recruitment. The trigger type may also be chosen to optimize egg maturity. However, the specific protocol is always individualized based on age, ovarian reserve, and previous response.

    Monitoring Frequency

    During stimulation, monitoring typically includes transvaginal ultrasound to count and measure follicles, and blood tests to check estradiol and progesterone levels. In PGT cycles, monitoring may be more frequent to ensure optimal timing for egg retrieval. Expect appointments every 1-2 days during the final week of stimulation. Your clinic will provide a schedule.

    Medication Timeline and Travel Planning

    For international patients, the medication timeline affects travel duration. Stimulation usually lasts 10-14 days, followed by egg retrieval and a recovery day. If you are traveling to Thailand, you will need to stay for at least 2-3 weeks for the stimulation and retrieval phase. Embryo biopsy and PGT analysis take additional time (typically 5-7 days for biopsy and 2-4 weeks for genetic results), but you may not need to remain in Thailand during the entire analysis period. Discuss with your clinic whether you can return home and come back for a frozen embryo transfer.

    Questions to Confirm with Your Clinic

    • Which protocol (antagonist or agonist) does the clinic recommend for my profile, and why?
    • What specific medications will be used, and what are their brand names and dosages?
    • How often will I need monitoring appointments, and at what times of day?
    • What is the estimated total cost of medications, and are they included in the package?
    • Can I obtain medications locally in Thailand, or should I bring them from home?
    • What is the protocol for trigger shot timing and egg retrieval scheduling?
    • How does PGT affect the number of eggs or embryos needed for a successful cycle?

    Important Considerations

    Medication protocols are not one-size-fits-all. Your clinic will tailor the protocol based on your ovarian reserve tests (e.g., AMH, AFC), age, and any previous IVF experience. Always follow your doctor’s instructions precisely. Do not adjust doses or timing without medical advice. Side effects such as bloating, mood swings, and injection site reactions are common but usually temporary. Ovarian hyperstimulation syndrome (OHSS) is a risk, especially in high-responder patients; your clinic will monitor for this.

    For international patients, ensure you have a clear plan for medication storage (some require refrigeration) and travel with necessary documentation. Confirm with your clinic whether they provide medications or if you need to purchase them from a local pharmacy.

    Frequently asked questions

    What is the difference between antagonist and agonist protocols for IVF?

    The antagonist protocol uses a GnRH antagonist to prevent premature ovulation and is shorter (about 10-12 days of stimulation). The agonist protocol uses a GnRH agonist to suppress the pituitary before stimulation and is longer (about 2-4 weeks total). Your doctor will recommend based on your ovarian reserve and medical history.

    How does PGT affect the IVF medication protocol?

    PGT requires enough eggs to produce multiple embryos for biopsy. Therefore, protocols aim to maximize egg yield, often using higher FSH doses or adding hMG. The trigger type may also be chosen to optimize egg maturity. However, the protocol is always individualized.

    How often will I need monitoring during stimulation?

    Monitoring typically occurs every 1-2 days during the final week of stimulation, including ultrasound and blood tests. Your clinic will provide a schedule.

    Can I bring my own IVF medications to Thailand?

    You should check with your clinic and Thai customs regulations. Some medications require a prescription and may be restricted. Most clinics can provide medications locally or guide you on procurement.

    How long do I need to stay in Thailand for the medication and retrieval phase?

    Typically 2-3 weeks for stimulation, egg retrieval, and recovery. Embryo biopsy and PGT analysis may take additional weeks, but you may not need to stay in Thailand during the entire analysis period.
