  • PGT-M vs PGT-SR in Thailand: What’s the Difference?

    If you are exploring IVF in Thailand and have a known genetic condition or a chromosomal rearrangement, you may come across two specific types of preimplantation genetic testing: PGT-M and PGT-SR. Both are performed on embryos created through IVF, but they screen for different types of genetic issues. Understanding the difference can help you have more informed conversations with your fertility team.

    At a Glance: PGT-M vs. PGT-SR

    • PGT-M screens for specific single gene disorders, such as cystic fibrosis, sickle cell anemia, or Huntington’s disease.
    • PGT-SR screens for chromosomal structural rearrangements, such as translocations or inversions, which can affect embryo development.
    • Both tests require IVF and embryo biopsy, and they are performed before embryo transfer.
    • Availability and specific protocols may vary between clinics in Thailand, so it’s important to ask about their laboratory capabilities.

    What Is PGT-M?

    PGT-M stands for preimplantation genetic testing for monogenic (single gene) disorders. It is used when one or both partners carry a known mutation for a specific genetic condition. The test looks for the presence or absence of that particular mutation in embryos created through IVF.

    PGT-M is typically considered by couples who:

    • Have a family history of a single gene disorder.
    • Are known carriers of an autosomal recessive or autosomal dominant condition.
    • Have a sex-linked disorder that they wish to avoid passing on.

    The goal is to identify embryos that do not carry the specific mutation, so that only those embryos are considered for transfer. However, PGT-M does not screen for all genetic conditions or chromosomal abnormalities—it is targeted to the specific mutation being tested.

    What Is PGT-SR?

    PGT-SR stands for preimplantation genetic testing for chromosomal structural rearrangements. This test is used when one or both partners have a chromosomal rearrangement, such as a balanced translocation or an inversion. These rearrangements may not cause health problems in the carrier, but they can lead to embryos with unbalanced chromosomal material, which may result in miscarriage or developmental issues.

    PGT-SR is typically considered by couples who:

    • Have a known balanced translocation or inversion.
    • Have experienced recurrent pregnancy loss or infertility that may be linked to chromosomal rearrangements.

    The test identifies embryos with a normal or balanced chromosomal arrangement, which are more likely to lead to a successful pregnancy.

    Key Differences Between PGT-M and PGT-SR

    Aspect PGT-M PGT-SR
    What it screens for Specific single gene mutations Chromosomal structural rearrangements
    Typical candidates Carriers of known genetic disorders Carriers of balanced translocations or inversions
    Method Targeted analysis for a specific mutation Analysis of chromosomal structure
    Outcome Identifies embryos without the specific mutation Identifies embryos with normal or balanced chromosomes

    How Are PGT-M and PGT-SR Performed?

    Both PGT-M and PGT-SR require IVF to create embryos. After fertilization, a small number of cells are removed from each embryo (a process called biopsy) and sent to a genetics laboratory for analysis. The testing process typically takes several days, after which the results are used to select embryos for transfer.

    In Thailand, the availability of PGT-M and PGT-SR may depend on the clinic’s laboratory capabilities and partnerships with genetics labs. Some clinics may offer both tests, while others may refer embryos to an external laboratory. It’s important to ask about the specific testing platform and turnaround time.

    Questions to Ask Your Clinic in Thailand

    When considering PGT-M or PGT-SR in Thailand, it’s helpful to ask your clinic specific questions to understand your options:

    • Do you offer PGT-M and PGT-SR on-site, or do you work with an external genetics laboratory?
    • What is the experience of your laboratory with these specific tests?
    • How long does the testing process take, and how does that affect the IVF timeline?
    • What are the costs associated with PGT-M or PGT-SR, and are they included in any IVF packages?
    • What are the limitations of the testing, and what results are possible (e.g., inconclusive, no result)?
    • How are embryos with abnormal results handled, and what are the options for disposal, donation, or further testing?

    Limitations and Considerations

    It’s important to understand that PGT-M and PGT-SR are not guarantees of a successful pregnancy or a healthy child. They are screening tools that can reduce the risk of transferring an embryo with a specific genetic issue, but they do not eliminate all risks. For example:

    • PGT-M only tests for the specific mutation requested; it does not screen for other genetic or chromosomal conditions.
    • PGT-SR may not detect all types of chromosomal rearrangements, and some embryos may have mosaicism (a mix of normal and abnormal cells).
    • Embryo biopsy carries a small risk of damage to the embryo, though this is rare.
    • Not all embryos may be suitable for testing, and some may not survive the biopsy process.

    Additionally, the accuracy of PGT depends on the laboratory’s techniques and the quality of the embryo biopsy. It’s essential to discuss the limitations with your fertility specialist and genetic counselor.

    Next Steps

    If you are considering PGT-M or PGT-SR in Thailand, here are some steps to help you move forward:

    1. Consult with a fertility specialist to review your medical history and determine if PGT is appropriate.
    2. Meet with a genetic counselor to understand the specific condition or rearrangement and the implications for your family.
    3. Ask your clinic about their experience with PGT-M and PGT-SR, including success rates and laboratory protocols.
    4. Clarify the costs, timeline, and any additional procedures required.
    5. Consider the emotional and ethical aspects of embryo testing and discuss them with your partner and support network.

    Frequently asked questions

    Can PGT-M and PGT-SR be done at the same time?

    Yes, it is possible to perform PGT-M and PGT-SR simultaneously on the same embryo biopsy, if both are indicated. This would require a laboratory that can analyze both the specific gene mutation and the chromosomal structure. However, not all clinics may offer combined testing, so it's important to ask about their capabilities.

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

    PGT-A (preimplantation genetic testing for aneuploidy) screens embryos for the correct number of chromosomes, which can help identify embryos with a higher chance of implantation. PGT-M screens for specific single gene disorders, and PGT-SR screens for chromosomal structural rearrangements. They are used for different purposes and may be used alone or in combination.

    Are PGT-M and PGT-SR available in all IVF clinics in Thailand?

    Availability may vary. Some clinics in Thailand have on-site genetics laboratories, while others may partner with external labs. It's best to ask your clinic directly about their PGT-M and PGT-SR services, including the specific testing platforms they use.

    How long does PGT-M or PGT-SR testing take?

    The testing process typically takes several days to a few weeks, depending on the laboratory and the complexity of the test. Your clinic can provide a more specific timeline based on their protocols.

    What are the risks of PGT-M and PGT-SR?

    The main risks are related to the IVF process and embryo biopsy. There is a small risk of embryo damage during biopsy, and the testing itself may have limitations, such as inconclusive results. It's important to discuss these risks with your fertility team.

  • How to Read PGT-A Results in Thailand: A Guide for Patients

    Receiving your PGT-A results can feel overwhelming. This guide explains the main result categories—euploid, aneuploid, and mosaic—in plain English, and offers practical questions to ask your clinic in Thailand. Always discuss your specific results with a qualified medical professional who knows your full history.

    At a glance: PGT-A result categories

    • Euploid: expected number of chromosomes, often considered “normal.”
    • Aneuploid: missing or extra chromosomes, often considered “abnormal.”
    • Mosaic: a mix of cells with different chromosome numbers.
    • No result: the test could not provide a clear answer.

    What is PGT-A?

    Preimplantation Genetic Testing for Aneuploidy (PGT-A) is a test that checks embryos for an abnormal number of chromosomes. It is performed on embryos created through IVF before a potential transfer. The test is optional and not a guarantee of pregnancy or a healthy baby. In Thailand, PGT-A is offered by many fertility clinics, but the way results are reported can vary.

    Understanding your PGT-A report

    Your report will typically list each embryo tested and a result for each. Here are the common terms you may see:

    Euploid

    An embryo with the expected number of chromosomes (46 in humans) is called euploid. This is often described as “normal.” Euploid embryos have the highest chance of implanting and developing, but they are not a guarantee of a live birth.

    Aneuploid

    An embryo with missing or extra chromosomes is aneuploid. For example, trisomy 21 (three copies of chromosome 21) is a type of aneuploidy. Most aneuploid embryos will not implant or will miscarry, but some can lead to a child with a genetic condition. Transferring an aneuploid embryo is generally not recommended, but your doctor will discuss your specific situation.

    Mosaic

    A mosaic embryo has a mixture of cells: some with the expected chromosome number and some with an abnormal number. Mosaic results are reported as a percentage, such as “20% mosaic.” The implications are not fully understood, and outcomes can vary. Some mosaic embryos may develop normally, while others may not. Your clinic can explain the specific level of mosaicism and what it might mean for your case.

    No result

    Sometimes the test fails to produce a clear result, for example, if the biopsy sample was insufficient or the DNA amplification failed. In such cases, you may have the option to retest or to proceed without PGT-A information.

    How to interpret your results with your clinic

    Your PGT-A report is a piece of the puzzle. Your doctor will consider your age, embryo quality, and medical history. Here are steps to help you understand your results:

    1. Ask for a clear explanation: Request that your doctor or genetic counselor explain each result in plain language.
    2. Discuss transfer options: Ask which embryos are suitable for transfer and why.
    3. Understand the limitations: PGT-A does not detect all genetic conditions or guarantee a healthy baby.
    4. Consider additional testing: In some cases, PGT-M or PGT-SR may be recommended for specific genetic disorders.

    Questions to ask your Thai clinic

    • What does “mosaic” mean in my report, and what percentage is considered high?
    • Are there any embryos that you would not recommend transferring?
    • What is the accuracy of this PGT-A test?
    • If I have no euploid embryos, what are my options?
    • Do you offer genetic counseling to help me understand the results?

    Next steps after receiving results

    Once you have your results, you may need to decide whether to transfer an embryo, consider further testing, or explore other options. Take your time and ask questions. Your clinic’s fertility specialist and genetic counselor are there to support you.

    Frequently asked questions

    What does a 'mosaic' PGT-A result mean?

    A mosaic result means the embryo has a mix of cells with different chromosome numbers. The percentage indicates the proportion of abnormal cells. The implications are not fully understood, and outcomes can vary. Your clinic can explain the specific level and what it might mean for your case.

    Can a PGT-A abnormal embryo result in a healthy baby?

    In rare cases, an embryo classified as aneuploid may still lead to a healthy baby, but this is uncommon. Most aneuploid embryos fail to implant or miscarry. Your doctor will discuss the risks and options based on your specific situation.

    Is PGT-A testing mandatory in Thailand?

    No, PGT-A is optional. It is offered to help select embryos with the expected number of chromosomes, but it is not required for all IVF patients. Your clinic can advise whether it may be beneficial for you.

    How long does it take to get PGT-A results in Thailand?

    The time can vary depending on the laboratory and the testing method. Typically, results may take several days to a few weeks. Your clinic will provide a specific timeline.

  • Understanding PGT-A Testing Costs in Thailand: A Guide for International Patients

    If you are considering IVF with preimplantation genetic testing for aneuploidy (PGT-A) in Thailand, understanding the cost structure is essential for planning. PGT-A testing fees are not a single fixed price; they are composed of several elements that can vary from clinic to clinic. This guide breaks down the typical cost components, explains why prices may differ, and provides questions to ask when requesting a transparent quote.

    At a Glance: Key Cost Components

    • IVF cycle fees (stimulation, egg retrieval, lab work)
    • Embryo biopsy fee
    • Genetic testing laboratory fee (per embryo or per cycle)
    • Shipping and handling (if samples are sent to an external lab)
    • Consultation and monitoring fees
    • Medication costs (often separate)

    What Does PGT-A Testing Cost Include?

    PGT-A testing involves several steps, each with its own cost. Here are the main components you will likely see in a clinic’s quote:

    IVF Cycle Costs

    PGT-A is performed on embryos created through IVF, so you will need to factor in the cost of an IVF cycle. This typically includes ovarian stimulation medications, ultrasound monitoring, blood tests, egg retrieval, and laboratory fertilization. Some clinics offer package deals that bundle IVF with PGT-A, which may be more cost-effective.

    Embryo Biopsy Fee

    On day 5 or 6 of embryo development, a few cells are removed from each embryo for testing. This procedure requires specialized equipment and expertise, and clinics charge a fee for the biopsy itself. The fee may be per embryo or per cycle.

    Genetic Testing Laboratory Fee

    The actual genetic analysis is performed by a laboratory, either in-house or external. The lab charges for the technology used to screen for chromosomal abnormalities. This fee is often quoted per embryo, but some clinics may offer a flat rate for a certain number of embryos.

    Shipping and Handling

    If your clinic sends samples to an external lab, there may be additional costs for shipping and handling. This is more common if the lab is located in another city or country.

    Why Do PGT-A Prices Vary Between Clinics?

    Several factors influence the total cost of PGT-A in Thailand:

    • Clinic location: Clinics in Bangkok may have higher overhead costs than those in other regions.
    • Laboratory type: In-house labs may offer lower prices than external labs, but external labs might have more advanced technology.
    • Number of embryos tested: Most clinics charge per embryo, so the total cost depends on how many embryos you have that are suitable for biopsy.
    • Included services: Some quotes include consultation, monitoring, and even medications, while others list them separately.
    • Package deals: Some clinics offer all-inclusive packages that can reduce the overall cost compared to paying for each component separately.

    How to Compare Quotes Effectively

    When you receive quotes from different clinics, it is important to compare like with like. Here are some tips:

    • Ask for a detailed breakdown of all fees, not just a total.
    • Clarify whether the quote includes the IVF cycle, biopsy, and genetic testing.
    • Check if medications are included or if they are an additional cost.
    • Ask about the number of embryos included in the quote and the cost for additional embryos.
    • Inquire about any potential extra charges, such as for embryo freezing or storage.

    Questions to Ask a Clinic About PGT-A Costs

    To avoid surprises, consider asking these questions when discussing PGT-A with a clinic:

    • What is the total cost for an IVF cycle with PGT-A, and what does it include?
    • Are there separate fees for the embryo biopsy and the genetic analysis?
    • Is the genetic testing done in-house or at an external lab? If external, are shipping costs included?
    • How many embryos are covered by the quoted price? What is the cost for additional embryos?
    • Are medications included in the quote? If not, what is the estimated cost?
    • Are there any additional fees for embryo freezing, storage, or future transfers?
    • Do you offer package deals that bundle PGT-A with other services?

    Next Steps: Getting a Transparent Quote

    Once you have a clear understanding of the cost components, you can approach clinics with confidence. Here is a simple checklist:

    1. Shortlist clinics that offer PGT-A and have a good reputation.
    2. Request a detailed written quote from each clinic.
    3. Compare the quotes based on the components listed above.
    4. Ask follow-up questions to clarify any vague items.
    5. Consider the clinic’s experience and success rates, not just the price.

    Remember that the cheapest option may not always be the best value. Quality of care and laboratory standards are equally important. Take your time to research and choose a clinic that meets your needs and budget.

    Frequently asked questions

    Is PGT-A testing in Thailand cheaper than in other countries?

    Thailand is often considered a cost-effective destination for fertility treatments, including PGT-A. However, prices can vary significantly between clinics, so it is important to compare detailed quotes. The total cost will depend on the clinic, the number of embryos tested, and whether you choose a package deal.

    Does PGT-A cost per embryo or per cycle?

    Most clinics charge for PGT-A on a per-embryo basis, but some may offer a flat rate for a certain number of embryos. It is essential to ask how the pricing works and what happens if you have more or fewer embryos than expected.

    Are there any hidden fees with PGT-A in Thailand?

    Potential additional costs include medications, embryo freezing and storage, and shipping if samples are sent to an external lab. To avoid surprises, ask for a detailed breakdown of all fees and clarify what is included in the quote.

    Can I get a package deal for IVF with PGT-A in Thailand?

    Many Thai clinics offer package deals that bundle IVF, biopsy, and genetic testing. These packages can be more cost-effective than paying for each component separately. Be sure to ask what the package includes and whether there are any exclusions.

  • Understanding Mosaic Embryos in PGT-A Results: A Guide for Patients in Thailand

    If you have received PGT-A results that describe an embryo as “mosaic,” you may be wondering what that means for your IVF journey. In simple terms, a mosaic embryo has a mix of cells with normal chromosomes and cells with abnormal chromosomes. This is different from a uniformly normal (euploid) embryo or a uniformly abnormal (aneuploid) embryo. Understanding your results is the first step in making informed decisions, but it is important to remember that every situation is unique and should be discussed with your fertility team.

    At a Glance: Key Points About Mosaic Embryos

    • Mosaic embryos contain both normal and abnormal cells.
    • Mosaicism is reported as a percentage or a level (low, medium, high).
    • Mosaic embryos may have the potential to develop into healthy babies, but outcomes vary.
    • Your clinic will consider the specific mosaic level and which chromosomes are involved.
    • Always ask your clinic for a detailed explanation of your results and your options.

    What Is a Mosaic Embryo?

    During embryo development, cells divide and sometimes errors occur in chromosome distribution. A mosaic embryo has a mixture of cells: some with the correct number of chromosomes (euploid) and some with an incorrect number (aneuploid). This is different from a non-mosaic embryo, where all cells have the same chromosomal status.

    Mosaicism can be detected through preimplantation genetic testing for aneuploidy (PGT-A), which analyzes a small sample of cells from the embryo. The test reports the proportion of abnormal cells, often as a percentage. For example, a result might say “20% mosaic” or “low-level mosaic.”

    How Are Mosaic Results Reported?

    PGT-A results typically categorize embryos as:

    • Euploid: all cells appear to have the normal number of chromosomes.
    • Aneuploid: all cells appear to have an abnormal number of chromosomes.
    • Mosaic: a mix of normal and abnormal cells.

    Mosaic results may be further described by the level of mosaicism (low, medium, high) and the specific chromosomes involved. Some laboratories report a percentage, such as “30% mosaic.” It is important to ask your clinic for a clear explanation of the terminology they use.

    What Does a Mosaic Result Mean for Transfer?

    The decision to transfer a mosaic embryo is complex and depends on many factors. Some studies suggest that mosaic embryos can result in healthy live births, but the risk of an abnormal pregnancy may be higher than with a euploid embryo. However, the exact risks are not fully known, and outcomes vary.

    Your fertility team will consider:

    • The specific level of mosaicism (low, medium, high).
    • Which chromosomes are affected.
    • Whether the abnormality is likely to be tolerated or cause health issues.
    • Your medical history and previous IVF outcomes.
    • Your personal preferences and values.

    Some clinics may recommend transferring a mosaic embryo if no euploid embryos are available, while others may advise against it. There is no universal rule, so it is essential to have a detailed discussion with your doctor.

    Questions to Ask Your Clinic About Mosaic Embryos

    When you receive mosaic results, consider asking your clinic the following questions:

    • What is the exact level of mosaicism in this embryo?
    • Which chromosomes are involved, and what is the potential impact?
    • What is your clinic’s policy on transferring mosaic embryos?
    • Are there any additional tests or consultations recommended?
    • What are the potential risks and benefits of transferring this embryo?
    • What is the likelihood of a healthy live birth with this embryo compared to other options?
    • Are there any follow-up tests during pregnancy that you would recommend?

    Next Steps: Making an Informed Decision

    After receiving mosaic results, take time to process the information and gather all the facts. Here is a simple checklist:

    1. Request a written copy of your PGT-A results and a detailed explanation.
    2. Schedule a consultation with your fertility specialist to discuss the findings.
    3. Ask about the specific chromosomes involved and the level of mosaicism.
    4. Discuss all available options, including transferring the mosaic embryo, further testing, or considering other embryos.
    5. Consider seeking a second opinion if you have any doubts.
    6. Take time to make a decision that feels right for you and your family.

    Remember, a mosaic result does not automatically mean an embryo is unusable, but it does require careful consideration. Your fertility team is there to guide you through the process.

    Understanding PGT-A Limitations

    PGT-A is a screening test, not a guarantee of a healthy baby. It cannot detect all genetic conditions, and the biopsy sample may not perfectly represent the entire embryo. Mosaicism itself can be challenging to interpret, and the technology has limitations. It is important to understand that PGT-A results are one piece of information in your decision-making process.

    • Confirm the accuracy of the original report.
    • Clarify ambiguous or uncertain results.
    • Explore alternative interpretations or additional testing options.
    • Gain peace of mind before making decisions about embryo transfer.

    It is important to note that a second opinion does not guarantee a different outcome, but it can provide additional perspective.

    How to Request Your PGT Data

    To get a second opinion, you will need access to your original PGT data. Contact your current clinic and request:

    • A copy of the full PGT report, including the summary and any detailed findings.
    • Raw data files, such as the genetic sequencing or array results, if available.
    • Information about the laboratory that performed the analysis and the specific PGT platform used.

    Some clinics may have policies about releasing raw data. Ask about the process and any associated fees. If you are working with a coordinator, they can assist with this request.

    Choosing a Geneticist or Laboratory for a Second Opinion

    When selecting a professional to review your PGT results, consider:

    • Qualifications and experience in PGT interpretation, especially for the type of PGT you had (PGT-A, PGT-M, or PGT-SR).
    • Whether they have access to the same or compatible technology to analyze your raw data.
    • Their approach to communicating results and uncertainties.

    You can ask your current clinic for recommendations or search for independent genetic counselors or reproductive geneticists in Thailand. Some international laboratories also offer remote second-opinion services.

    Questions to Ask During a Second Opinion

    Prepare a list of questions to make the most of your consultation:

    • What is your interpretation of my PGT results?
    • Are there any areas of uncertainty or mosaicism that need further consideration?

    Understanding PGT Types and Result Interpretation

    PGT includes different types, each with specific purposes:

    • PGT-A (aneuploidy screening) checks for abnormal numbers of chromosomes.
    • PGT-M (monogenic disorders) tests for specific genetic conditions.
    • PGT-SR (structural rearrangements) detects chromosomal structural changes.

    Results may be reported as euploid (normal), aneuploid (abnormal), or mosaic (a mix of normal and abnormal cells). Interpretation can be nuanced, and a second opinion may help clarify what a result means for your specific situation.

    What to Do After Receiving a Second Opinion

    After your second opinion, you may have a clearer picture. Consider the following steps:

    • Discuss the findings with your current fertility clinic to see how they align.
    • Ask about the possibility of additional testing, such as re-biopsy or further genetic analysis, if recommended.
    • Take time to process the information and consult with your support network.

  • Understanding PGT-A Biopsy Timing in Thailand: What to Expect

    If you are considering preimplantation genetic testing for aneuploidy (PGT-A) as part of your IVF journey in Thailand, one of the most common questions is: when does the biopsy actually happen? The answer is usually on day 5 or day 6 after fertilization, when the embryo has reached the blastocyst stage. This timing is important because it allows the embryologist to safely remove a few cells from the trophectoderm, the part that will become the placenta, without harming the inner cell mass that will form the fetus.

    In this guide, we explain the typical timing of PGT-A biopsy, what the process involves, and what you should ask your clinic to feel confident about the embryology lab handling your embryos.

    At a Glance: PGT-A Biopsy Timing

    • Biopsy is usually performed on day 5 or day 6 after fertilization.
    • Embryos must reach the blastocyst stage before biopsy.
    • The embryologist removes 3–5 cells from the trophectoderm.
    • The biopsied cells are sent for genetic analysis, while the embryo is frozen.
    • Results typically take several days to a few weeks, depending on the lab.

    Why Day 5 or Day 6?

    Embryos develop in stages. After fertilization, the embryo divides and grows, reaching the blastocyst stage around day 5 or day 6. At this point, the embryo has two distinct cell types: the inner cell mass (which becomes the fetus) and the trophectoderm (which becomes the placenta). Biopsying at this stage allows the embryologist to remove cells from the trophectoderm, which is less likely to affect the embryo’s development compared to earlier stages.

    Performing the biopsy earlier, such as on day 3, is possible but less common for PGT-A. Day 3 biopsy involves removing a cell from the cleavage-stage embryo, which may be more invasive. Most clinics in Thailand prefer day 5 or day 6 biopsy because it is safer and provides more cells for analysis.

    The PGT-A Biopsy Process in Thailand

    The biopsy procedure is performed in an embryology laboratory by a trained embryologist. Here is a step-by-step overview of what typically happens:

    1. Embryo culture: After fertilization, embryos are cultured in the lab for about 5 to 6 days until they reach the blastocyst stage.
    2. Hatching assistance: The embryologist may use a laser to create a small opening in the zona pellucida, the outer shell of the embryo, to facilitate cell removal.
    3. Cell removal: Using a fine pipette, the embryologist gently aspirates 3–5 cells from the trophectoderm.
    4. Biopsy sample handling: The removed cells are placed in a tube for genetic analysis.
    5. Embryo freezing: After biopsy, the embryo is vitrified (frozen) while awaiting results.
    6. Genetic analysis: The biopsied cells are sent to a genetics laboratory for PGT-A testing, which checks for chromosomal abnormalities.

    The entire biopsy procedure is delicate and requires precision. The embryologist’s skill and the laboratory’s quality are critical to the safety and accuracy of the process.

    What to Expect After the Biopsy

    After the biopsy, your embryos will be frozen. This is standard practice because the genetic analysis takes time, and the results are needed before a frozen embryo transfer (FET) can be planned. The freezing process, called vitrification, is well-established and widely used in Thailand.

    The time to receive PGT-A results can vary. Some labs may provide results within a few days, while others may take a week or more. Your clinic will give you a timeline based on their specific laboratory arrangements.

    Once the results are available, your doctor will discuss which embryos are chromosomally normal (euploid) and suitable for transfer. It is important to remember that PGT-A does not guarantee a pregnancy or a healthy baby; it is a screening tool that can help reduce the risk of miscarriage and certain chromosomal conditions.

    Questions to Ask About the Embryology Lab

    When choosing a clinic in Thailand for PGT-A, it is essential to ask about the embryology lab’s experience and protocols. Here are some questions to consider:

    • How many PGT-A cycles does the lab perform per year?
    • What is the embryologist’s experience with blastocyst biopsy?
    • Does the lab use laser-assisted hatching for biopsy?
    • How many cells are typically removed, and what is the success rate of obtaining a diagnosis?
    • What is the lab’s policy on embryo re-biopsy if the first sample is inconclusive?
    • How are embryos identified and tracked to avoid mix-ups?
    • What is the turnaround time for PGT-A results?
    • Is the genetics laboratory accredited or certified?

    These questions can help you gauge the quality and reliability of the embryology lab, which is a key factor in the success of PGT-A.

    Factors That Can Affect Biopsy Timing

    While day 5 or day 6 is the standard, the exact timing can vary based on embryo development. Some embryos may reach the blastocyst stage earlier or later. In some cases, an embryo may not be suitable for biopsy on day 5 and may be observed until day 6 or even day 7. However, not all embryos will reach the blastocyst stage, and some may not be biopsied at all.

    Your clinic will monitor embryo development and decide the best time for biopsy. It is important to understand that not every embryo will be suitable for PGT-A, and the number of embryos available for testing can vary.

    Next Steps: Planning Your PGT-A Cycle in Thailand

    If you are considering PGT-A in Thailand, here is a checklist to help you move forward:

    • Research clinics that offer PGT-A and have experience with blastocyst biopsy.
    • Schedule a consultation to discuss your medical history and whether PGT-A is appropriate for you.
    • Ask about the clinic’s embryology lab and genetics laboratory arrangements.
    • Clarify the costs involved, including biopsy, genetic analysis, and embryo freezing.
    • Understand the legal and regulatory aspects of PGT-A in Thailand, as they can vary.
    • Plan for the timeline, including the biopsy day and the wait for results.

    Remember, PGT-A is not a mandatory step for everyone. Your doctor can help you decide if it is right for your situation.

    Conclusion

    PGT-A biopsy timing in Thailand typically falls on day 5 or day 6 after fertilization, when embryos have reached the blastocyst stage. The process is safe and well-established, but it requires a skilled embryologist and a high-quality lab. By asking the right questions and understanding what to expect, you can approach this step with confidence.

    Frequently asked questions

    Is PGT-A biopsy painful for the embryo?

    Embryos do not have a nervous system, so they do not feel pain. The biopsy is performed under a microscope, and the embryologist removes a few cells from the outer layer of the blastocyst. This is a delicate procedure, but it is not painful for the embryo.

    Can PGT-A biopsy damage the embryo?

    There is a small risk that the biopsy could affect the embryo, but it is generally considered safe when performed by an experienced embryologist. The removal of trophectoderm cells is less likely to harm the embryo than biopsy at earlier stages. However, no procedure is without risk, and your clinic should discuss the potential risks with you.

    How long does it take to get PGT-A results in Thailand?

    The turnaround time for PGT-A results can vary depending on the genetics laboratory. Some labs may provide results within a few days, while others may take a week or more. Your clinic will give you a specific timeline based on their arrangements.

    What happens if the biopsy sample is inconclusive?

    In rare cases, the biopsied cells may not yield enough DNA for analysis, leading to an inconclusive result. In such situations, the clinic may offer a re-biopsy of the embryo, but this depends on the embryo's condition and the clinic's policies. It is important to ask about this possibility beforehand.

    Does PGT-A guarantee a healthy baby?

    No, PGT-A does not guarantee a healthy baby. It is a screening tool that can identify embryos with the correct number of chromosomes, which may reduce the risk of miscarriage and certain chromosomal conditions. However, it does not test for all genetic disorders, and other factors can affect pregnancy outcomes.

  • PGT-A in Thailand: What to Know Before You Test

    What is PGT-A?

    PGT-A (preimplantation genetic testing for aneuploidy) is a test performed on embryos created through IVF. It checks for the correct number of chromosomes. Embryos with the usual 46 chromosomes are called euploid; those with missing or extra chromosomes are aneuploid. Aneuploidy is a common cause of failed implantation and miscarriage.

    PGT-A does not test for every genetic condition. It focuses on chromosomal number, not specific gene mutations. For single-gene disorders, a different test called PGT-M is used.

    How PGT-A Works

    PGT-A is performed in three main steps:

    1. Embryo biopsy: A few cells are removed from a day-5 or day-6 embryo (blastocyst stage). The biopsy is usually done on the trophectoderm, which becomes the placenta.
    2. Genetic analysis: The cells are sent to a genetics laboratory. Techniques such as next-generation sequencing (NGS) are commonly used to count chromosomes.
    3. Transfer decision: Based on results, a euploid embryo can be selected for transfer. Aneuploid embryos are generally not transferred, though some may be re-tested or discussed with a genetic counselor.

    The biopsy is performed by an embryologist, and the analysis is done in a separate genetics lab. The entire process adds time to an IVF cycle because embryos must be frozen while waiting for results.

    What PGT-A Results Mean

    Results are typically reported as:

    • Euploid: normal chromosome number, suitable for transfer.
    • Aneuploid: abnormal chromosome number, not usually transferred.
    • Mosaic: a mix of normal and abnormal cells. Mosaic embryos may have reduced implantation potential, but some can lead to healthy births. Decisions are made on a case-by-case basis.
    • No result: sometimes the biopsy or analysis fails, and no result is obtained.

    PGT-A is not a guarantee of a healthy baby. It reduces the risk of chromosomal abnormalities but does not eliminate all risks.

    Who Might Consider PGT-A

    PGT-A may be considered in several situations:

    • Advanced maternal age (usually over 35)
    • Previous miscarriage or failed IVF cycles
    • Severe male factor infertility
    • Known chromosomal translocation in either partner
    • Previous pregnancy with a chromosomal abnormality

    However, PGT-A is not necessary for everyone. Younger women with no known risks may not benefit significantly. Your doctor can help you weigh the potential advantages and limitations.

    PGT-A in Thailand: What to Consider

    Thailand has many IVF clinics that offer PGT-A. When researching, consider the following:

    • Lab accreditation: Ask if the genetics laboratory is accredited by an international body, such as CAP or ISO.
    • Experience: Inquire about the lab’s volume of PGT-A cases and their experience with embryo biopsy.
    • Turnaround time: Results may take several days to a few weeks. Ask for the expected timeline.
    • Reporting: Ask how results are reported and whether you will receive a detailed report.
    • Counseling: Check if genetic counseling is available to help interpret results.

    Costs for PGT-A in Thailand vary widely. The price typically includes the biopsy, genetic analysis, and sometimes the initial consultation. Always ask for a detailed breakdown and confirm what is included.

    Questions to Ask Your Clinic

    Before proceeding with PGT-A, ask your clinic:

    • What is your experience with PGT-A?
    • Which genetic laboratory do you use, and is it accredited?
    • How many cells are biopsied, and what is the success rate of getting a result?
    • How long will it take to receive results?
    • How are mosaic embryos handled?
    • What is the total cost, and what does it include?
    • Is genetic counseling available?

    Alternatives to PGT-A

    PGT-A is one option, but not the only one. Alternatives include:

    • IVF without PGT-A: Embryos are selected based on morphology (appearance) alone.
    • Non-invasive PGT (niPGT): A newer approach that analyzes DNA in the culture medium, but it is less established.
    • Prenatal testing: After pregnancy, tests like NIPT or amniocentesis can check for chromosomal abnormalities.

    Discuss these options with your doctor to make an informed choice.

    Next Steps

    If you are considering PGT-A in Thailand, start by:

    1. Researching clinics and their PGT-A services.
    2. Preparing a list of questions from this guide.
    3. Scheduling a consultation to discuss your specific situation.
    4. Confirming all costs and timelines in writing.

    For more information, explore our PGT in Thailand guide, browse other guides, or check our FAQ section.

    Frequently asked questions

    Is PGT-A the same as PGT-M?

    No. PGT-A screens for chromosomal number abnormalities (aneuploidy), while PGT-M tests for specific single-gene disorders. They are different tests used for different purposes.

    Does PGT-A guarantee a healthy baby?

    No. PGT-A reduces the risk of chromosomal abnormalities but does not eliminate all risks. It does not test for all genetic conditions, and other factors can affect pregnancy outcome.

    How long does PGT-A take in Thailand?

    The timeline varies by clinic and laboratory. Typically, results may take several days to a few weeks. Ask your clinic for their specific turnaround time.

    What is a mosaic embryo?

    A mosaic embryo has a mix of normal and abnormal cells. It may have reduced implantation potential, but some mosaic embryos can lead to healthy births. Decisions are made on a case-by-case basis with genetic counseling.

    Is PGT-A necessary for all IVF patients?

    No. PGT-A is not necessary for everyone. It may be recommended for certain situations, such as advanced maternal age or recurrent miscarriage. Your doctor can help you decide if it is right for you.

  • How to Read PGT Results in Thailand: A Guide for Patients

    Understanding Your PGT Results: A Starting Point

    When you undergo preimplantation genetic testing (PGT) in Thailand, the results can feel complex and emotional. In simple terms, PGT looks at embryos created through IVF to check for certain genetic conditions before transfer. The results help you and your medical team decide which embryos to consider for transfer. However, PGT results are not a guarantee of pregnancy or a healthy baby—they are one piece of information in your fertility journey.

    This guide explains the main types of PGT results, what they mean, and how to discuss them with your doctor and genetic counselor. Always rely on your clinic’s medical team for personalized interpretation.

    At a Glance: Key Points About PGT Results

    • PGT-A screens embryos for the correct number of chromosomes (euploid vs. aneuploid).
    • PGT-M looks for specific single-gene disorders.
    • PGT-SR checks for structural rearrangements of chromosomes.
    • Results may be reported as euploid, aneuploid, or mosaic.
    • Mosaic embryos have a mix of normal and abnormal cells.
    • Your doctor and genetic counselor are the best people to explain what results mean for your situation.

    What Do PGT Results Mean?

    Euploid Results

    An embryo with a euploid result has the expected number of chromosomes (46 in humans) with no detectable abnormalities in the tested chromosomes. This is often considered a positive result, but it does not guarantee implantation or a live birth. Many factors affect whether an embryo will develop, including the embryo’s quality and the health of the uterus.

    Aneuploid Results

    An aneuploid embryo has an abnormal number of chromosomes—either missing or extra. For example, trisomy 21 (Down syndrome) is a type of aneuploidy. Aneuploid embryos often do not implant or may lead to miscarriage. However, some aneuploidies are compatible with life, and the decision to transfer such an embryo is complex and should be made with thorough genetic counseling.

    Mosaic Results

    A mosaic embryo has a mixture of cells with normal chromosomes and cells with abnormal chromosomes. The level of mosaicism (the percentage of abnormal cells) can vary. Mosaic embryos may have reduced implantation potential, but some can develop into healthy babies. The clinical significance of mosaicism is still being studied, and decisions about transferring a mosaic embryo require careful discussion with your medical team.

    Types of PGT and Their Results

    Type of PGT What It Screens For Typical Result Categories
    PGT-A (Aneuploidy) Correct number of chromosomes Euploid, aneuploid, mosaic
    PGT-M (Monogenic) Specific single-gene disorders (e.g., cystic fibrosis, sickle cell) Affected, unaffected, carrier (depending on the condition)
    PGT-SR (Structural Rearrangement) Chromosomal structural changes (e.g., translocations) Balanced, unbalanced, normal

    Note: The exact terminology may vary by laboratory. Always ask your clinic for a clear explanation of your specific report.

    How to Read Your PGT Report

    PGT reports can look technical, but they usually include:

    • Embryo identification number
    • Biopsy date and testing method
    • Chromosome analysis results (for PGT-A)
    • Gene analysis results (for PGT-M)
    • Interpretation (e.g., euploid, aneuploid, mosaic)
    • Recommendations for further testing or counseling

    If you see terms like “no result” or “inconclusive,” it means the test did not provide a clear answer. This can happen for technical reasons, and your clinic may suggest re-biopsy or additional testing.

    Questions to Ask Your Doctor and Genetic Counselor

    Before discussing your results, prepare a list of questions. Here are some to consider:

    • What does this result mean for the chance of implantation and live birth?
    • Are there any health risks for the child if this embryo is transferred?
    • What are the options for further testing, such as confirmatory prenatal testing?
    • How does the mosaicism level affect the recommendation?
    • Are there alternative embryos to consider?
    • What is the cost and timeline for any additional testing?

    Your genetic counselor can explain the implications in detail and help you make an informed decision.

    Next Steps After Receiving PGT Results

    1. Schedule a follow-up appointment with your fertility doctor to review the results.
    2. Request a referral to a genetic counselor if you haven’t already spoken with one.
    3. Take time to process the information—don’t rush into decisions.
    4. Discuss your options for embryo transfer, including whether to consider mosaic embryos.
    5. Ask about the need for prenatal testing if you proceed with a transfer.

    Important Limitations of PGT

    PGT is a screening tool, not a guarantee. It cannot detect all genetic conditions, and it does not eliminate the risk of miscarriage or birth defects. Also, PGT is not necessary for everyone. Your doctor may recommend it based on your age, family history, or previous pregnancy losses. Always discuss whether PGT is right for you.

    Frequently asked questions

    What is the difference between euploid and aneuploid embryos?

    A euploid embryo has the correct number of chromosomes (46), while an aneuploid embryo has an abnormal number—either missing or extra chromosomes. Euploid embryos are generally considered more likely to implant and develop, but they are not a guarantee of pregnancy. Aneuploid embryos may fail to implant or lead to miscarriage, but some can result in a live birth, so decisions are made on a case-by-case basis with genetic counseling.

    What does a mosaic embryo result mean?

    A mosaic embryo has a mix of cells with normal chromosomes and cells with abnormal chromosomes. The level of mosaicism varies. Mosaic embryos may have a lower chance of implantation, but some can develop into healthy babies. The clinical significance is still being studied, so it's important to discuss the specific level and your options with your doctor and genetic counselor.

    Can PGT results guarantee a healthy baby?

    No. PGT is a screening test that checks for certain genetic conditions, but it cannot detect all disorders or guarantee a healthy baby. Many factors affect pregnancy and child health, including embryo quality, uterine environment, and prenatal care. PGT results are one tool to help you make informed decisions, not a promise of outcome.

    What should I do if my PGT result is inconclusive?

    If your PGT result is inconclusive, it means the test did not provide a clear answer. This can happen for technical reasons. Your clinic may recommend re-biopsy, additional testing, or a discussion about the risks and benefits of transferring an embryo with an inconclusive result. Always ask your medical team for guidance.

    Is PGT mandatory for IVF in Thailand?

    No, PGT is not mandatory for all IVF patients. It is an optional test that may be recommended based on factors like maternal age, family history of genetic disorders, or previous miscarriages. Your doctor will discuss whether PGT is appropriate for your situation. You can also ask about the costs and benefits before deciding.

  • PGT-A Cost Breakdown in Thailand: What to Expect and What to Ask

    If you are exploring IVF with preimplantation genetic testing for aneuploidy (PGT-A) in Thailand, one of the first questions is likely: what does it actually cost? The answer is not a single number. PGT-A pricing is built from several components, and clinics may quote them differently. This guide breaks down the typical cost categories, explains why prices vary, and gives you a checklist of questions to ask so you can compare quotes fairly.

    At a Glance: PGT-A Cost Components

    • Embryo biopsy: The procedure to remove a few cells from the embryo.
    • Genetic analysis: The laboratory testing of those cells for chromosomal abnormalities.
    • Shipping and handling: If the biopsy is sent to an external lab, there may be logistics fees.
    • Add-ons: Optional services like embryo freezing, extended culture, or consultation with a genetic counselor.

    Keep in mind that published prices are rarely final. Your total will depend on your treatment plan, the number of embryos tested, and the clinic’s specific pricing structure.

    Understanding the Main Cost Components

    Embryo Biopsy

    The biopsy is performed by an embryologist who removes a small number of cells from the trophectoderm (the part that becomes the placenta) of a day-5 or day-6 blastocyst. This step requires specialized equipment and expertise. The cost may be included in the overall IVF package or charged separately. Ask whether the biopsy fee covers all embryos or is per embryo.

    Genetic Analysis

    This is the laboratory work that analyzes the biopsied cells to check for chromosomal abnormalities. The analysis can be done in-house or at an external genetics lab. The fee may be per embryo or per cycle. Some clinics offer a package for a certain number of embryos, with additional charges for extra embryos. Clarify whether the quoted price includes the analysis of all biopsied embryos or only a set number.

    Shipping and Handling

    If your clinic sends the biopsy samples to a partner laboratory, there may be shipping and handling fees. These can include courier costs, packaging, and possibly customs or import fees if the lab is in another country. Ask if these are itemized in your quote or bundled into the analysis fee.

    Add-Ons and Ancillary Services

    Other services may be recommended or optional, such as:

    • Embryo freezing (cryopreservation) and storage
    • Extended embryo culture to blastocyst stage
    • Genetic counseling before or after testing
    • Repeat biopsy if the first attempt is inconclusive
    • Additional testing like PGT-M or PGT-P, if needed

    These add-ons can significantly affect your total cost. Always ask for a full list of potential extras and their prices.

    Why PGT-A Prices Vary

    Several factors influence the final cost of PGT-A in Thailand:

    • Number of embryos tested: More embryos mean higher analysis fees.
    • Laboratory type: In-house labs may offer different pricing than external labs.
    • Technology used: Next-generation sequencing (NGS) is common, but other methods may have different costs.
    • Clinic location: Prices can differ between Bangkok and other cities.
    • Included services: Some quotes include consultation, ultrasound, and medications; others do not.

    Because of this variability, it is essential to request a detailed, itemized quote from each clinic you consider.

    What to Look for in a Transparent Quote

    A transparent quote should clearly list each component and its price. Look for the following:

    • Biopsy fee (per embryo or per cycle)
    • Genetic analysis fee (per embryo or per cycle)
    • Shipping and handling, if applicable
    • Embryo freezing and storage fees
    • Any additional lab or administrative fees
    • Whether the quote is valid for a specific period

    If a clinic gives you a single lump sum, ask for a breakdown. If they say “all inclusive,” ask what exactly is included and what is not.

    Questions to Ask Before You Commit

    To avoid surprises, ask these questions during your consultation:

    1. Is the biopsy fee per embryo or per cycle?
    2. Does the genetic analysis fee cover all biopsied embryos or only a certain number?
    3. Are there any additional charges for shipping or handling?
    4. What happens if a biopsy result is inconclusive? Is there a repeat biopsy fee?
    5. Are embryo freezing and storage included in the quote? For how long?
    6. Are there any discounts for testing multiple embryos?
    7. What is the payment schedule? Are there any refund policies?

    Write down the answers and compare them across clinics.

    Next Steps: Comparing Your Options

    Once you have itemized quotes from a few clinics, you can compare them fairly. Consider not only the price but also the clinic’s experience with PGT-A, the laboratory’s accreditation, and the support you will receive. Remember that the cheapest option may not always be the best fit for your medical situation.

    Frequently asked questions

    What is typically included in a PGT-A quote in Thailand?

    A PGT-A quote usually includes the embryo biopsy procedure and the genetic analysis of the biopsied cells. Some clinics may also include shipping to an external lab, embryo freezing, or a certain number of embryos tested. Always ask for an itemized breakdown to see exactly what is covered.

    Are there hidden costs with PGT-A in Thailand?

    Potential additional costs include shipping and handling, repeat biopsy if the first attempt is inconclusive, embryo freezing and storage, and genetic counseling. Some clinics may charge extra for testing more than a set number of embryos. Ask for a full list of possible fees before starting treatment.

    How can I compare PGT-A prices between clinics?

    Request an itemized quote from each clinic that lists the biopsy fee, analysis fee, shipping, and any add-ons. Compare the total cost for your specific situation, considering the number of embryos you expect to test. Also consider the clinic's experience and laboratory quality, not just the price.

    Does the number of embryos affect the PGT-A cost?

    Yes, most clinics charge per embryo for the genetic analysis, and sometimes for the biopsy as well. If you have more embryos, the total cost will be higher. Some clinics offer packages for a set number of embryos, with additional fees for extra ones.

  • PGT-M Testing in Thailand: A Guide for Couples at Risk of Genetic Disorders

    If you and your partner carry a gene for a single-gene disorder such as cystic fibrosis, thalassemia, or Huntington’s disease, you may be exploring ways to reduce the chance of passing it on to your child. Preimplantation genetic testing for monogenic disorders (PGT-M) is one option offered in some IVF clinics in Thailand. This guide explains what PGT-M is, how it fits into an IVF cycle, what it can and cannot tell you, and what to consider when planning treatment in Thailand.

    What is PGT-M?

    PGT-M is a genetic test performed on embryos created through IVF. It looks for specific single-gene disorders that the parents are known to carry. Unlike PGT-A (which screens for chromosomal abnormalities) or PGT-SR (which checks for structural rearrangements like translocations), PGT-M targets a particular inherited condition. The goal is to identify embryos that do not carry the disorder, so that a clinician can transfer one of those embryos into the uterus.

    PGT-M is not a general health screen. It only tests for the specific mutation(s) you and your partner have been identified to carry. It does not guarantee a healthy baby, and it cannot detect all genetic or non-genetic conditions.

    Who might consider PGT-M?

    Couples may consider PGT-M if they:

    • Both carry a recessive disorder (e.g., thalassemia, sickle cell anemia)
    • One partner carries a dominant disorder (e.g., Huntington’s disease)
    • One partner carries an X-linked disorder (e.g., hemophilia)
    • Have had a previous child affected by a single-gene disorder
    • Have a family history of a specific genetic condition

    Before PGT-M, both partners usually undergo genetic counseling and carrier testing to confirm the specific mutation. This step is essential because the test is designed around your unique genetic profile.

    How does PGT-M work in an IVF cycle?

    PGT-M is performed as part of an IVF cycle. Here is a general step-by-step overview:

    1. Genetic counseling and carrier testing: You and your partner meet with a genetic counselor to review your family history and confirm the mutation. This may involve blood or saliva tests.
    2. IVF stimulation and egg retrieval: You undergo ovarian stimulation, and eggs are retrieved in a minor surgical procedure.
    3. Fertilization and embryo culture: Eggs are fertilized with sperm in the lab, and embryos are cultured for several days (usually to blastocyst stage).
    4. Embryo biopsy: A few cells are removed from each embryo. This is usually done on day 5 or 6 of development.
    5. Genetic analysis: The biopsied cells are sent to a genetics laboratory for PGT-M analysis. The lab uses techniques such as polymerase chain reaction (PCR) to look for the specific mutation.
    6. Embryo transfer: After results are available (typically within a week or two), a clinician selects an embryo that does not carry the disorder for transfer.

    Not all embryos may be suitable for transfer. Some may carry the disorder, and some may not survive the biopsy or thawing process. The number of embryos available for transfer depends on your age, ovarian response, and other factors.

    What does PGT-M cost in Thailand?

    The cost of PGT-M in Thailand varies widely depending on the clinic, the complexity of the genetic test, and the number of embryos tested. In general, you can expect to pay for:

    • IVF cycle costs (stimulation medications, monitoring, egg retrieval, lab fees)
    • Embryo biopsy fees
    • Genetic analysis fees (often per embryo)
    • Genetic counseling and carrier testing (if not already done)
    • Medications for uterine preparation and transfer

    Because prices are not standardized, it is essential to request a detailed quote from each clinic. Ask what is included and what is not. Some clinics may offer package deals, but be sure to understand what happens if you need additional cycles or if no embryos are suitable for transfer.

    Choosing a clinic in Thailand for PGT-M

    When researching PGT-M in Thailand, consider the following:

    • Accreditation and laboratory standards: Check if the clinic and its associated genetics laboratory have international accreditation (e.g., ISO, CAP).
    • Experience with PGT-M: Ask how many PGT-M cycles the clinic has performed and for which conditions.
    • Genetic counseling: Does the clinic provide genetic counseling before and after testing?
    • Turnaround time: How long does it take to receive results? This may affect your treatment schedule.
    • Communication: Will you receive results in English? Who explains them to you?
    • Support services: Does the clinic offer translation, travel coordination, or psychological support?

    It is also wise to ask about the laboratory that will perform the genetic analysis. Some clinics send biopsies to an external lab, which may affect logistics and costs.

    Questions to ask a clinic about PGT-M

    Before committing to a clinic, consider asking:

    • What is the exact cost of PGT-M, and what does it include?
    • How many embryos will be biopsied, and is there a minimum number?
    • What is the success rate for PGT-M cycles in your clinic? (Ask for their own data, not general statistics.)
    • What happens if no embryos are free of the disorder?
    • Can we have our embryos frozen and tested later?
    • Do you offer genetic counseling as part of the package?
    • What is your policy on embryo disposal or donation if we have unused embryos?

    Limitations and considerations

    PGT-M is a powerful tool, but it has limitations:

    • Not 100% accurate: There is a small risk of misdiagnosis or inconclusive results. Confirmatory testing during pregnancy (e.g., amniocentesis) is often recommended.
    • Embryo loss: Not all embryos will survive the biopsy or freezing process.
    • No guarantee of pregnancy: Even with a healthy embryo, implantation may not occur.
    • Ethical and legal considerations: Some countries have regulations about embryo testing and selection. Thailand has its own legal framework, which you should discuss with your clinic.
    • Emotional and financial burden: The process can be stressful and costly, especially if multiple cycles are needed.

    It is important to have realistic expectations and to discuss all options with your doctor and genetic counselor.

    Next steps

    If you are considering PGT-M in Thailand, start by:

    1. Consulting with a genetic counselor to confirm your carrier status and understand your risks.
    2. Researching IVF clinics that offer PGT-M and have experience with your specific condition.
    3. Requesting detailed cost estimates and asking about their laboratory partnerships.
    4. Planning for the time required, including any travel and accommodation.
    5. Preparing questions about embryo handling, results, and follow-up testing.

    Frequently asked questions

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

    PGT-A screens embryos for chromosomal abnormalities (aneuploidy), while PGT-M tests for a specific single-gene disorder that the parents are known to carry. PGT-A is often used to improve IVF success rates, whereas PGT-M is used to avoid passing on a particular genetic condition.

    How long does PGT-M testing take in Thailand?

    The genetic analysis itself typically takes about one to two weeks after embryo biopsy. However, the entire IVF cycle, including stimulation, retrieval, and transfer, can take several weeks. Your clinic will provide a timeline based on your individual treatment plan.

    Is PGT-M legal in Thailand?

    Thailand has regulations governing assisted reproductive technology, including genetic testing of embryos. The legal framework is complex and may change. It is essential to consult with your chosen clinic and possibly a legal expert to understand the current rules and any restrictions.

    Can PGT-M guarantee a healthy baby?

    No. PGT-M can identify embryos that do not carry the specific disorder tested, but it cannot guarantee a pregnancy or a healthy baby. There are risks of misdiagnosis, and other genetic or non-genetic conditions may still occur. Confirmatory prenatal testing is often recommended.

    What happens if all embryos have the genetic disorder?

    If no embryos are free of the disorder, the clinic will discuss options with you. These may include using donor eggs or sperm, considering adoption, or deciding not to proceed with transfer. Your clinic and genetic counselor can provide support and guidance.
