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

    Receiving your PGT-A results can feel overwhelming. This guide explains the common result categories—euploid, aneuploid, and mosaic—and the limitations of the test, so you can have a more informed conversation with your doctor in Thailand.

    At a Glance: PGT-A Result Categories

    • Euploid: Normal chromosome number, often considered transferable.
    • Aneuploid: Abnormal chromosome number, usually not recommended for transfer.
    • Mosaic: Mix of normal and abnormal cells, with varying clinical implications.

    What Is PGT-A?

    Preimplantation Genetic Testing for Aneuploidy (PGT-A) is a screening test performed on embryos created through IVF. It checks for the correct number of chromosomes. Having too many or too few chromosomes can lead to implantation failure, miscarriage, or genetic conditions like Down syndrome.

    PGT-A is not a guarantee of a healthy baby, and it does not test for all genetic disorders. It is one tool among many in fertility treatment.

    Understanding Your PGT-A Report

    Your PGT-A report will typically list each embryo tested and its result. Here are the main categories:

    Euploid

    Euploid embryos have the expected number of chromosomes (46 in humans). These are often prioritized for transfer because they have the highest chance of implanting and developing normally. However, a euploid result does not guarantee pregnancy or a healthy child.

    Aneuploid

    Aneuploid embryos have an abnormal number of chromosomes. For example, trisomy 21 (three copies of chromosome 21) causes Down syndrome. Most aneuploid embryos will not implant or will miscarry. Transfer of aneuploid embryos is generally not recommended, but your doctor can discuss any rare exceptions.

    Mosaic

    Mosaic embryos have a mixture of normal and abnormal cells. The percentage of abnormal cells and which chromosomes are affected influence the outcome. Some mosaic embryos can develop into healthy babies, but the risk of miscarriage or genetic issues is higher than with euploid embryos. Your doctor will help you weigh the options.

    Limitations of PGT-A

    PGT-A is a screening test, not a diagnostic test. It cannot detect all genetic problems, and it does not assess the embryo’s overall quality or potential for implantation. The biopsy samples only a few cells, which may not represent the entire embryo. Additionally, PGT-A cannot predict the health of the child after birth.

    In Thailand, PGT-A is performed in specialized laboratories. The accuracy of the test depends on the laboratory’s techniques and the embryo’s stage at biopsy. Discuss these factors with your clinic.

    How to Discuss Results with Your Doctor

    When you receive your PGT-A report, prepare questions for your doctor. Here are some to consider:

    • What does this result mean for my chances of pregnancy?
    • Are there any additional tests I should consider?
    • What is the recommended next step for each embryo?
    • How does my age or medical history affect the interpretation?

    Your doctor in Thailand will explain the results in the context of your individual situation. Take notes and ask for clarification if anything is unclear.

    Next Steps After PGT-A Results

    After reviewing your results, you and your doctor will decide which embryos to transfer. If you have no euploid embryos, you may consider additional IVF cycles or alternative options. If you have mosaic embryos, you may discuss the risks and benefits of transfer.

    Remember that PGT-A is optional and not suitable for everyone. Your doctor can help you understand if it is right for you.

    Questions to Ask Your Clinic

    • What is the laboratory’s experience with PGT-A?
    • How are mosaic embryos classified and reported?
    • What is the policy on transferring mosaic embryos?
    • Are there any additional costs for PGT-A?

    Checklist for Your Next Appointment

    • Bring a copy of your PGT-A report.
    • List your questions in advance.
    • Ask for a clear explanation of each result.
    • Discuss all options, including transfer, further testing, or new cycles.

    Frequently asked questions

    What does a PGT-A result of 'euploid' mean?

    A euploid result means the embryo has the expected number of chromosomes. It is often considered suitable for transfer, but it does not guarantee pregnancy or a healthy baby.

    Can a mosaic embryo result in a healthy baby?

    Yes, some mosaic embryos can develop into healthy babies, but the risk of miscarriage or genetic issues is higher than with euploid embryos. Your doctor can help you understand the specific risks based on the percentage and type of mosaicism.

    Is PGT-A accurate?

    PGT-A is a screening test with limitations. It samples only a few cells, which may not represent the entire embryo. It cannot detect all genetic conditions. Discuss the accuracy and limitations with your clinic.

    What should I do if all my embryos are aneuploid?

    If all embryos are aneuploid, your doctor may recommend considering another IVF cycle, using donor eggs or sperm, or exploring other options. The best next step depends on your individual situation.

  • PGT-A vs PGT-M vs PGT-SR in Thailand: Which Genetic Test Is Right for You?

    If you are exploring IVF in Thailand, you may have encountered the terms PGT-A, PGT-M, and PGT-SR. These are three types of preimplantation genetic testing (PGT) that can be performed on embryos created through IVF. Each test serves a different purpose: PGT-A screens for chromosomal abnormalities (aneuploidy), PGT-M detects specific single-gene disorders, and PGT-SR identifies structural rearrangements of chromosomes. This guide explains the clinical purposes of each test, how they differ, and what to consider when deciding which test—if any—may be appropriate for your situation.

    At a Glance: PGT-A, PGT-M, and PGT-SR

    • PGT-A (Preimplantation Genetic Testing for Aneuploidy) checks embryos for the correct number of chromosomes.
    • PGT-M (Preimplantation Genetic Testing for Monogenic Disorders) looks for specific inherited single-gene conditions.
    • PGT-SR (Preimplantation Genetic Testing for Structural Rearrangements) detects chromosomal structural changes like translocations.

    What Is PGT-A?

    PGT-A is designed to screen embryos for aneuploidy—having an abnormal number of chromosomes. Aneuploidy is a common cause of implantation failure and miscarriage. By identifying embryos with the correct number of chromosomes, PGT-A may help reduce the risk of miscarriage and improve the chances of a successful pregnancy, though it does not guarantee success.

    PGT-A is often considered for patients of advanced maternal age, those with a history of recurrent miscarriage, or couples who have experienced repeated IVF failures. However, it is not recommended for everyone; your fertility specialist can help determine if PGT-A is appropriate based on your medical history and circumstances.

    What Is PGT-M?

    PGT-M is used when one or both partners carry a known genetic mutation for a monogenic disorder—a condition caused by a single gene. Examples include cystic fibrosis, sickle cell anemia, and Huntington’s disease. PGT-M identifies embryos that have inherited the mutation, allowing the transfer of embryos that are unaffected by the specific condition.

    This test requires prior genetic analysis of the parents to identify the specific mutation. PGT-M is typically recommended for couples with a known genetic risk, and it can be used to avoid passing on a serious inherited condition.

    What Is PGT-SR?

    PGT-SR is designed for individuals who carry a structural rearrangement of their chromosomes, such as a translocation or inversion. These rearrangements may not cause health problems in the carrier but can lead to unbalanced chromosomes in embryos, increasing the risk of miscarriage or birth defects. PGT-SR identifies embryos with balanced chromosomal arrangements, which are more likely to result in a healthy pregnancy.

    PGT-SR is often recommended for couples where one partner has a known chromosomal rearrangement, a history of recurrent miscarriages, or previous pregnancies with unbalanced chromosomes.

    Key Differences at a Glance

    Test Purpose Common Indications
    PGT-A Screens for aneuploidy (abnormal chromosome number) Advanced maternal age, recurrent miscarriage, repeated implantation failure
    PGT-M Detects specific single-gene disorders Known genetic mutation in one or both partners
    PGT-SR Identifies structural chromosomal rearrangements Known translocation or inversion, recurrent miscarriage

    How Are the Tests Performed?

    All three types of PGT require IVF to create embryos. After fertilization, embryos are cultured for several days, and a small number of cells are biopsied. The biopsied cells are then analyzed in a genetics laboratory. The process is similar for PGT-A, PGT-M, and PGT-SR, but the specific genetic analysis differs:

    • PGT-A uses techniques like next-generation sequencing (NGS) to count chromosomes.
    • PGT-M uses targeted analysis to detect the specific mutation, often requiring a customized test for the family.
    • PGT-SR uses chromosomal analysis to detect structural rearrangements.

    It is important to note that PGT is not a routine part of IVF for all patients. The decision to use PGT should be made in consultation with your fertility specialist and a genetic counselor, who can explain the benefits, limitations, and risks.

    Which PGT Test Is Right for You?

    Choosing the right PGT test depends on your medical history and genetic background. Here are some general considerations:

    • If you have no known genetic conditions but are concerned about chromosomal abnormalities due to age or previous miscarriages, PGT-A may be discussed.
    • If you or your partner carry a known mutation for a single-gene disorder, PGT-M may be recommended.
    • If you or your partner have a chromosomal rearrangement, PGT-SR may be suggested.

    In some cases, more than one test may be used. For example, a couple with a known translocation and advanced maternal age might consider both PGT-SR and PGT-A. Your clinic will guide you based on your specific situation.

    Questions to Ask Your Clinic

    When considering PGT in Thailand, it is helpful to ask your clinic specific questions:

    • What types of PGT do you offer, and which do you recommend for my situation?
    • How many embryos typically reach the biopsy stage, and what is the success rate for biopsy?
    • How long does the genetic analysis take, and how will results be communicated?
    • Are there additional costs for PGT, and what do they include?
    • Do you have a genetic counselor on staff to discuss results?

    Limitations and Considerations

    PGT is a powerful tool, but it has limitations. It does not guarantee a successful pregnancy or a healthy baby. PGT-A cannot detect all chromosomal abnormalities, and PGT-M and PGT-SR are specific to the conditions tested. Additionally, embryo biopsy carries a small risk of damage, and not all embryos may survive the process. It is also important to understand that PGT is not a substitute for prenatal testing during pregnancy.

    In Thailand, the availability and regulations regarding PGT may vary. It is essential to confirm with your chosen clinic about the specific tests they offer, the laboratory standards, and any legal or ethical considerations.

    Next Steps

    If you are considering PGT as part of your IVF journey in Thailand, here are some practical steps:

    1. Consult with a fertility specialist to review your medical history and discuss whether PGT is appropriate.
    2. If PGT-M or PGT-SR is indicated, seek genetic counseling to understand the implications.
    3. Ask your clinic about their experience with PGT and the laboratory they use.
    4. Clarify all costs and timelines before starting treatment.
    5. Make an informed decision based on your personal circumstances and medical advice.

    Frequently asked questions

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

    Yes, it is possible to perform PGT-A and PGT-M simultaneously on the same embryo biopsy. This is often done when a couple has a known genetic mutation and also wants to screen for chromosomal abnormalities. However, not all clinics may offer combined testing, so it is important to confirm with your clinic.

    Is PGT mandatory for all IVF patients in Thailand?

    No, PGT is not mandatory for all IVF patients. It is an optional test that may be recommended based on specific medical indications. Your fertility specialist will discuss whether PGT is appropriate for your situation.

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

    PGT-A screens for an abnormal number of chromosomes (aneuploidy), while PGT-SR detects structural rearrangements such as translocations or inversions. PGT-A is more common and can be used for general screening, whereas PGT-SR is specifically for individuals with known chromosomal structural changes.

    How long does PGT testing take?

    The time required for PGT testing can vary depending on the type of test and the laboratory. Typically, results may be available within a few days to a couple of weeks. Your clinic will provide a timeline based on their specific procedures.

  • How to Read a PGT-A Report in Thailand: A Guide for International Patients

    Receiving your PGT-A report can feel overwhelming. It contains technical terms and numbers that may be hard to interpret on your own. This guide explains the structure of a typical PGT-A report, what the results mean, and why you should always discuss them with your clinician before making decisions.

    At a Glance: Key Points About Your PGT-A Report

    • PGT-A screens embryos for chromosomal abnormalities (aneuploidy).
    • The report shows the number of chromosomes in each embryo and whether they are normal (euploid), abnormal (aneuploid), or mosaic.
    • Mosaic results mean a mix of normal and abnormal cells.
    • Inconclusive results may occur due to technical issues or low DNA quality.
    • Your clinician will interpret the report in the context of your medical history and treatment plan.

    What Is PGT-A?

    Preimplantation Genetic Testing for Aneuploidy (PGT-A) is a test performed on embryos created through IVF. It checks for the correct number of chromosomes. Humans typically have 46 chromosomes in each cell. An embryo with too many or too few chromosomes is called aneuploid and may fail to implant or lead to miscarriage. PGT-A helps identify embryos that are more likely to be chromosomally normal.

    It is important to note that PGT-A does not guarantee a pregnancy or a healthy baby. It is one tool among many in the IVF process.

    Understanding the Structure of a PGT-A Report

    While reports may vary by laboratory, most include the following sections:

    Embryo Identification

    Each embryo is given a unique identifier, often a number or code. This helps you and your clinic track which embryo corresponds to which result.

    Chromosome Copy Number

    This section lists the 23 pairs of chromosomes (or 24, including sex chromosomes) and indicates whether each pair has the expected number. A normal result shows two copies of each autosome and either XX or XY for sex chromosomes. An abnormal result may show extra or missing chromosomes, such as trisomy 21 (three copies of chromosome 21) or monosomy X (one X chromosome).

    Mosaicism

    Mosaic embryos have a mixture of cells with normal and abnormal chromosome counts. The report may indicate the percentage of abnormal cells. For example, a 20% mosaic embryo has some abnormal cells, but the majority are normal. Mosaicism can affect the embryo’s potential to develop, but some mosaic embryos can result in healthy births. The clinical significance depends on the specific chromosomes involved and the percentage of mosaicism.

    Inconclusive Results

    Sometimes the test cannot provide a clear result. This can happen if the DNA sample is too small, degraded, or if there are technical issues. An inconclusive result does not mean the embryo is abnormal; it simply means the test could not determine the chromosome status. Your clinician may recommend re-testing or considering the embryo with caution.

    How to Interpret the Results

    Interpreting a PGT-A report requires clinical expertise. Here are some general principles:

    • Euploid (normal): The embryo has the expected number of chromosomes. This is generally considered favorable for transfer.
    • Aneuploid (abnormal): The embryo has extra or missing chromosomes. Transferring such an embryo may lead to implantation failure, miscarriage, or a child with a genetic condition. Most clinics do not recommend transferring aneuploid embryos.
    • Mosaic: The embryo has a mix of normal and abnormal cells. The decision to transfer a mosaic embryo is complex and depends on the specific chromosomes involved, the percentage of mosaicism, and your medical history. Some clinics may offer transfer if no euploid embryos are available.
    • Inconclusive: The result is unclear. Your clinician may suggest re-biopsy or consider the embryo as low priority.

    Remember that PGT-A is a screening test, not a diagnostic test. It cannot detect all genetic conditions or guarantee a healthy baby.

    Questions to Ask Your Clinic

    When you receive your report, consider asking your clinician the following questions:

    • What does this result mean for my chances of pregnancy?
    • Are there any chromosomes that are more concerning than others?
    • If the embryo is mosaic, what is the percentage and which chromosomes are affected?
    • What are the options if all embryos are abnormal or inconclusive?
    • Should we consider additional testing, such as PGT-M for a specific genetic condition?

    Next Steps After Receiving Your Report

    After reviewing your report with your clinician, you may decide to:

    • Proceed with transferring a euploid embryo.
    • Discuss the possibility of transferring a mosaic embryo, if applicable.
    • Consider further testing or a new IVF cycle if no suitable embryos are available.
    • Seek a second opinion from another specialist.

    Your clinician will guide you based on your individual circumstances.

    Limitations of PGT-A

    PGT-A has limitations. It cannot detect all chromosomal abnormalities, such as balanced translocations or small deletions. It also does not test for single-gene disorders (that would be PGT-M) or structural rearrangements (PGT-SR). Additionally, the test is performed on a few cells from the embryo, which may not represent the entire embryo. There is also a small risk of misdiagnosis.

    It is essential to understand that PGT-A is not suitable for everyone. Your clinician will determine if it is appropriate for your situation.

    Conclusion

    Reading a PGT-A report is a complex process that requires professional interpretation. Use this guide to understand the basics, but always rely on your clinician to explain what the results mean for you. If you have questions, do not hesitate to ask your clinic for clarification.

    Frequently asked questions

    What does a normal PGT-A result mean?

    A normal (euploid) result means the embryo has the expected number of chromosomes. This is generally considered favorable for transfer, but it does not guarantee pregnancy or a healthy baby.

    What is a mosaic embryo?

    A mosaic embryo has a mix of normal and abnormal cells. The report may show the percentage of abnormal cells. Some mosaic embryos can lead to healthy births, but the decision to transfer depends on the specific chromosomes and percentage.

    What should I do if my PGT-A result is inconclusive?

    An inconclusive result means the test could not determine the chromosome status. Discuss with your clinician whether re-testing is possible or how to consider the embryo in your treatment plan.

    Can PGT-A detect all genetic problems?

    No, PGT-A only screens for aneuploidy (extra or missing chromosomes). It does not detect single-gene disorders or structural rearrangements. Other tests like PGT-M or PGT-SR are needed for those.

  • How Long After PGT-A Results Can Embryo Transfer Happen in Thailand?

    Understanding the Timeline from PGT-A Results to Embryo Transfer

    After receiving your PGT-A results, you may be eager to know when your embryo transfer can happen. In Thailand, the timeline is not fixed; it depends on several factors, including your menstrual cycle, clinic scheduling, and whether you need any additional preparation. This guide explains the typical steps between receiving results and scheduling a frozen embryo transfer (FET), helping you plan your journey with realistic expectations.

    At a Glance: Key Steps After PGT-A Results

    • Receive and review PGT-A results with your fertility specialist.
    • Discuss which embryos are suitable for transfer.
    • Plan your menstrual cycle for the transfer (natural or medicated cycle).
    • Coordinate with the clinic for scheduling and any required travel arrangements.
    • Undergo the transfer procedure and await pregnancy test.

    Step 1: Reviewing PGT-A Results with Your Specialist

    Once your PGT-A results are available, your fertility specialist will explain the chromosomal status of each embryo. This discussion is crucial to decide which embryo(s) to transfer. The timing of this review can vary, but it typically happens within a few days to a week after results are released. During this consultation, you will also discuss the number of embryos to transfer and any additional testing or procedures recommended.

    Step 2: Planning Your Menstrual Cycle for Transfer

    Embryo transfer is timed to your menstrual cycle to optimize the chances of implantation. You may have a natural cycle or a medicated cycle with hormone replacement therapy. The choice depends on your individual circumstances and clinic protocols. Your clinic will guide you on when to start cycle preparation, which may involve taking medications to prepare your uterine lining. This preparation typically takes about two to four weeks, but the exact duration varies.

    Step 3: Clinic Scheduling and Travel Coordination

    After your cycle is planned, the clinic will schedule the transfer on a specific date. This date is based on your cycle day and embryo development stage. If you are traveling to Thailand, you will need to coordinate your travel dates with the clinic’s schedule. It is advisable to confirm the transfer date well in advance and plan your stay accordingly. Some patients may need to be in Thailand for a few days to a week around the transfer, but this varies.

    Step 4: The Transfer Procedure and Aftercare

    The embryo transfer itself is a relatively simple procedure that does not require anesthesia. After the transfer, you may be advised to rest briefly and then resume normal activities. A pregnancy test is typically scheduled about 10-14 days after the transfer. Your clinic will provide specific instructions for post-transfer care and medication.

    Factors That Can Affect the Timeline

    Several factors can influence how long you wait between PGT-A results and transfer:

    • Embryo status: If embryos need additional testing or if you are considering further genetic testing, this can add time.
    • Your health: Any medical conditions or uterine issues may require treatment before transfer.
    • Clinic schedule: Availability of the clinic and your specialist can affect scheduling.
    • Personal preferences: You may choose to delay transfer for personal or medical reasons.

  • Understanding PGT-A Results Timeline in Thailand: What to Expect

    If you are waiting for PGT-A results after an IVF cycle in Thailand, you likely want to know how long it will take and what happens next. While every laboratory has its own workflow, most PGT-A results are available within a few weeks. However, the exact timing can vary based on several factors, including the number of embryos tested, the laboratory’s schedule, and whether additional genetic testing is needed. This guide explains the typical timeline, what can affect it, and how to plan your next steps.

    At a Glance: PGT-A Results Timeline

    • Biopsy is usually performed on day 5 or day 6 of embryo development.
    • Results typically arrive within 1-2 weeks after the biopsy, but some clinics may take longer.
    • Factors like embryo freezing, transport to an external lab, and repeat testing can extend the wait.
    • Your clinic will schedule a follow-up consultation to discuss results and next steps.

    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 often used to help select embryos with the highest chance of implantation and a healthy pregnancy. PGT-A is not a guarantee of success, and it is not necessary for everyone. Your fertility specialist can help you decide if PGT-A is appropriate for your situation.

    How Long Does PGT-A Take in Thailand?

    The PGT-A process involves several steps, each with its own time requirement:

    1. Embryo biopsy: On day 5 or 6 after fertilization, a few cells are removed from the embryo’s outer layer (trophectoderm). This is done in the IVF laboratory.
    2. Sample preparation and shipping: If the biopsy is sent to an external genetic laboratory, the sample must be packaged and transported. This can add a day or two.
    3. Genetic analysis: The laboratory performs the genetic analysis, which typically takes several days to a week.
    4. Result reporting: Once the analysis is complete, the laboratory sends the results to your clinic. Your clinic will then review them and schedule a consultation with you.

    In total, you can expect to wait about 1 to 2 weeks after the biopsy for your PGT-A results. However, some clinics may provide results sooner, while others may take longer. It is best to ask your clinic for their specific timeline.

    Factors That Can Affect the Waiting Time

    Several factors can influence how long you wait for PGT-A results:

    • Number of embryos tested: Testing more embryos may take longer, though many labs process batches efficiently.
    • Laboratory workload: Busy periods may cause delays.
    • External vs. in-house lab: If your clinic sends samples to an external laboratory, shipping and scheduling can add time.
    • Need for repeat testing: Occasionally, a sample may not yield enough DNA, and the test may need to be repeated, which extends the timeline.
    • Additional genetic testing: If you are also having PGT-M (for a specific genetic condition) or PGT-SR (for chromosomal rearrangements), the analysis may take longer.

    What Happens After You Receive PGT-A Results?

    Once your results are ready, your clinic will schedule a follow-up appointment to explain them. During this consultation, you will discuss:

    • The number of embryos that are chromosomally normal (euploid), abnormal (aneuploid), or mosaic (a mix of normal and abnormal cells).
    • The potential for implantation and pregnancy for each embryo.
    • Your options for a frozen embryo transfer (FET) or additional testing.

    It is important to remember that PGT-A results are not a guarantee of a successful pregnancy. Even a normal embryo may not implant, and other factors such as maternal age and uterine health play a role.

    How to Plan for the Next Steps

    While you wait for results, you can take practical steps to prepare:

    • Ask your clinic about their typical turnaround time so you know what to expect.
    • Discuss your embryo transfer plan with your doctor, including whether you will have a frozen transfer in a subsequent cycle.
    • Consider your emotional well-being – waiting can be stressful, so plan activities that help you relax.
    • Prepare questions for your follow-up consultation, such as what the results mean for your chances of pregnancy and whether any additional testing is recommended.

    Questions to Ask Your Clinic About PGT-A Timing

    • How long do PGT-A results typically take at your clinic?
    • Is the genetic testing done in-house or at an external laboratory?
    • Will I be notified as soon as results are available, or will I need to wait for a scheduled appointment?
    • What happens if the test needs to be repeated?
    • How will I receive my results – through a phone call, email, or in-person consultation?

    Next-Step Checklist

    • Confirm your clinic’s PGT-A turnaround time.
    • Ask about the process for receiving results.
    • Schedule a follow-up consultation to discuss results.
    • Discuss your embryo transfer plan with your doctor.
    • Take care of your physical and emotional health while waiting.

    Some clinics may offer expedited testing, but this is not always possible. The timeline depends on the laboratory's process and the complexity of the analysis. Discuss your options with your clinic.

    What should I do while waiting for PGT-A results?

    While waiting, you can prepare by asking your clinic about their typical turnaround time, discussing your embryo transfer plan with your doctor, and taking care of your emotional well-being. It's also helpful to prepare questions for your follow-up consultation.

  • PGT-A vs PGT-M vs PGT-SR: Understanding Genetic Testing Options in Thailand

    If you are exploring IVF in Thailand, you may come across terms like PGT-A, PGT-M, and PGT-SR. These are different types of preimplantation genetic testing (PGT) that can be performed on embryos before transfer. Each test serves a distinct purpose, and understanding the differences can help you have more informed conversations with your fertility team. This guide explains what each test looks for, when it might be used, and what to consider when comparing options.

    What Is PGT?

    Preimplantation genetic testing (PGT) is a procedure that involves taking a small sample of cells from an embryo created through IVF. The sample is then analyzed in a laboratory to look for specific genetic information. PGT is not a routine step for every IVF cycle; it is typically recommended based on individual medical history, age, or genetic risk factors.

    There are three main types of PGT:

    • PGT-A (aneuploidy screening)
    • PGT-M (monogenic disorders)
    • PGT-SR (structural rearrangements)

    Each type answers a different question about the embryo.

    PGT-A: Screening for Chromosomal Number

    PGT-A, previously known as preimplantation genetic screening (PGS), checks embryos for an abnormal number of chromosomes, a condition called aneuploidy. Humans typically have 46 chromosomes in each cell. Having an extra or missing chromosome can lead to implantation failure, miscarriage, or conditions such as Down syndrome.

    PGT-A is often considered for:

    • Women of advanced maternal age
    • Couples with a history of recurrent miscarriage
    • Couples with repeated implantation failure
    • Couples where the male partner has severe sperm abnormalities

    It is important to note that PGT-A does not test for every genetic condition. It only screens for chromosomal number abnormalities, not for specific gene mutations.

    PGT-M: Testing for Single-Gene Disorders

    PGT-M is used when there is a known risk of passing on a specific inherited condition caused by a mutation in a single gene. Examples include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, and Huntington’s disease. This test identifies embryos that carry the gene mutation, allowing the transfer of embryos without the disorder.

    PGT-M is typically recommended when:

    • One or both partners are carriers of a known genetic disorder
    • There is a family history of a specific single-gene condition
    • A previous child has been affected by such a condition

    Because PGT-M requires knowing the exact genetic mutation, it often involves a preparatory workup to develop a customized test for each couple.

    PGT-SR: Detecting Structural Chromosomal Changes

    PGT-SR is designed for couples where one partner carries a structural rearrangement of chromosomes, such as a translocation or inversion. These rearrangements may not cause health problems in the carrier, but they can lead to embryos with unbalanced chromosomal material, increasing the risk of miscarriage or birth defects.

    PGT-SR is considered when:

    • One partner has a known chromosomal rearrangement
    • There is a history of recurrent miscarriages linked to chromosomal abnormalities
    • A previous pregnancy had an unbalanced chromosomal arrangement

    This test helps identify embryos with a normal or balanced chromosomal structure, which may have a higher chance of leading to a healthy pregnancy.

    Key Differences at a Glance

    Test Purpose Typical Indications
    PGT-A Screens for abnormal chromosome number Advanced maternal age, recurrent miscarriage, repeated implantation failure
    PGT-M Detects specific single-gene mutations Known carrier status or family history of a genetic disorder
    PGT-SR Identifies structural chromosomal rearrangements Known translocation or inversion in a partner, recurrent miscarriage

    How Are the Tests Performed?

    All PGT types follow a similar process: after IVF fertilization, embryos are cultured for several days, and a biopsy is taken from the trophectoderm (the cells that will become the placenta). The biopsy is then sent to a genetics laboratory for analysis. The embryo is frozen while waiting for results.

    The main differences lie in the laboratory techniques used:

    • PGT-A typically uses next-generation sequencing (NGS) to count chromosomes.
    • PGT-M uses polymerase chain reaction (PCR) or other methods to detect specific gene mutations.
    • PGT-SR may use NGS or other techniques to analyze chromosomal structure.

    Your clinic will advise on the specific technology they use and the timeline for results.

    Which Test Should You Choose?

    The choice between PGT-A, PGT-M, and PGT-SR depends on your medical history and genetic background. There is no one-size-fits-all answer. Here are some steps to help you decide:

    1. Consult with a genetic counselor to review your family history and any known genetic risks.
    2. Undergo carrier screening if you have not already, to identify potential recessive conditions.
    3. Discuss your IVF history with your fertility specialist, including any previous miscarriages or implantation failures.
    4. Ask your clinic which PGT types they offer and whether they have experience with your specific situation.

    Remember, PGT is not a guarantee of a successful pregnancy or a healthy baby. It is a screening tool that can provide information to help guide embryo selection.

    Questions to Ask Your Clinic

    When comparing PGT options in Thailand, consider asking:

    • Which PGT tests do you offer, and what is the laboratory accreditation?
    • How many embryos typically survive the biopsy and freezing process?
    • What is the turnaround time for results?
    • Are there additional costs for genetic counseling or carrier screening?
    • How do you handle inconclusive results or mosaicism?

    Next Steps

    If you are considering PGT in Thailand, start by gathering your medical records and any prior genetic testing results. Then, schedule consultations with fertility clinics that offer PGT services. Use this guide to ask informed questions and understand the purpose of each test.

    Frequently asked questions

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

    PGT-A screens embryos for an abnormal number of chromosomes (aneuploidy), while PGT-M tests for specific single-gene disorders when there is a known genetic risk. PGT-A is often used for age-related or unexplained fertility issues, whereas PGT-M is used for couples who carry a specific gene mutation.

    Is PGT-SR the same as PGT-A?

    No. PGT-SR is used when one partner has a structural chromosomal rearrangement, such as a translocation. It looks for unbalanced chromosomal material. PGT-A only checks the number of chromosomes, not their structure.

    Can PGT-A detect all genetic disorders?

    No. PGT-A only screens for chromosomal number abnormalities. It does not detect single-gene disorders or structural rearrangements. For those, PGT-M or PGT-SR would be needed.

    Do I need PGT if I am young and healthy?

    PGT is not necessary for everyone. It is typically recommended based on specific medical indications, such as advanced maternal age, recurrent miscarriage, or known genetic risks. Your fertility specialist can help you decide if PGT is appropriate for you.

    How long does PGT testing take in Thailand?

    The timeline can vary depending on the clinic and the type of test. Typically, results may take several days to a few weeks. Your clinic will provide a specific timeline based on their laboratory processes.

  • How Many Embryos Should You Biopsy for PGT-A in Thailand?

    When planning PGT-A (preimplantation genetic testing for aneuploidy) in Thailand, one of the first questions is: how many embryos should you biopsy? The answer depends on several personal factors, and there is no single number that fits everyone. This guide explains what influences the decision and helps you prepare for a conversation with your fertility clinic.

    At a Glance: Key Factors in Embryo Count

    • Age: Younger women typically produce more chromosomally normal embryos, so fewer may need testing.
    • Embryo quality: Higher-quality embryos may have a better chance of being normal, but quality alone doesn’t guarantee it.
    • Financial considerations: PGT-A adds to the cost of IVF, so the number biopsied affects your budget.
    • Clinic policy: Some clinics have minimum or maximum numbers for biopsy; ask about their approach.

    Understanding PGT-A and Embryo Biopsy

    PGT-A screens embryos for chromosomal abnormalities before transfer. During IVF, embryos are cultured to the blastocyst stage (usually day 5 or 6), and a few cells are removed from the outer layer (trophectoderm) for testing. The biopsy is performed in a laboratory, and the embryos are frozen while awaiting results.

    The number of embryos you biopsy is the number that reach the blastocyst stage and are suitable for biopsy. Not all fertilized eggs will develop to this stage, so the starting number of eggs and embryos is also relevant.

    Factors That Influence How Many Embryos to Biopsy

    Age and Ovarian Reserve

    Age is a major factor in embryo aneuploidy rates. As women age, a higher percentage of embryos are expected to be chromosomally abnormal. Therefore, older women may need to biopsy more embryos to have a reasonable chance of finding at least one normal embryo. However, age is not the only factor; ovarian reserve (measured by AMH and antral follicle count) also affects how many eggs and embryos you produce.

    Embryo Quality and Development

    Embryos are graded based on their appearance and development. Higher-grade embryos are more likely to be normal, but even high-quality embryos can be abnormal. Some clinics recommend biopsying all embryos that reach the blastocyst stage, regardless of grade, to maximize information. Others may suggest biopsying only the best-quality embryos to reduce costs.

    Financial Considerations

    PGT-A is an additional cost on top of IVF. The cost per embryo can vary, and some clinics offer packages for a certain number. You’ll need to decide how many embryos you can afford to test, balancing the desire for information with your budget. Ask for a detailed breakdown of costs before committing.

    Previous IVF Cycles and Genetic History

    If you’ve had previous miscarriages or failed transfers, you may be more inclined to test more embryos. Similarly, if you have a known chromosomal abnormality or are considering PGT-M (for single gene disorders), the number of embryos biopsied may be influenced by the need to find embryos that are both unaffected and chromosomally normal.

    How Many Embryos Do You Need? A Decision Framework

    There is no magic number, but you can approach the decision systematically:

    1. Estimate your expected number of blastocysts: Based on your age, ovarian reserve, and previous cycles, your doctor can give you a rough estimate.
    2. Consider your family goals: How many children do you hope to have? This affects how many normal embryos you might want.
    3. Understand the probability: Ask your clinic for age-based statistics on the likelihood of a normal embryo, but remember these are population averages, not guarantees.
    4. Set a budget: Determine how much you can spend on PGT-A and how many embryos that covers.
    5. Discuss with your clinic: Some clinics have policies on minimum or maximum numbers for biopsy. Ask about their experience and recommendations.

    Questions to Ask Your Clinic

    • How many embryos do you recommend biopsying in my situation, and why?
    • What is the cost per embryo for PGT-A, and are there package deals?
    • What is your policy on biopsying lower-grade embryos?
    • How many embryos typically reach the blastocyst stage for someone my age?
    • What is the turnaround time for results, and how does that affect my cycle?

    Next Steps: Making Your Decision

    Deciding how many embryos to biopsy is a personal choice. Take your time, gather information, and consult with your fertility team. Remember that PGT-A is a screening tool, not a guarantee of pregnancy or a healthy baby. It can reduce the risk of transferring an abnormal embryo, but it doesn’t eliminate all risks.

    For more information on PGT in Thailand, see our PGT in Thailand guide. You may also find our other guides and FAQ helpful.

    Frequently asked questions

    Is there a minimum number of embryos required for PGT-A?

    Some clinics may have a minimum number of embryos they recommend for biopsy, often around 3-5, to increase the chance of finding a normal embryo. However, this is not a universal rule. You should ask your clinic about their specific policy and how it applies to your situation.

    Can I biopsy only one embryo for PGT-A?

    Technically, you can biopsy a single embryo, but it may not be cost-effective or informative. If you have only one embryo, testing it can still provide valuable information, but you should discuss the likelihood of it being normal with your doctor.

    Does embryo quality affect the number I should biopsy?

    Yes, embryo quality can influence the decision. Higher-quality embryos are more likely to be normal, so you might need fewer to find a normal one. However, even high-quality embryos can be abnormal, so some clinics recommend testing all available blastocysts.

    How does age affect the number of embryos to biopsy?

    As age increases, the percentage of normal embryos typically decreases. Therefore, older women may need to biopsy more embryos to have a reasonable chance of finding at least one normal embryo. Your doctor can provide age-specific estimates.

  • How to Prepare for PGT-A Biopsy in Thailand: A Practical Checklist

    If you are scheduled for a PGT-A cycle in Thailand, you may be wondering how to prepare for the embryo biopsy step. PGT-A (preimplantation genetic testing for aneuploidy) checks embryos for the correct number of chromosomes before transfer. The biopsy itself is a delicate laboratory procedure that happens after fertilization, and your preparation focuses on coordination, communication, and practical planning rather than medical intervention. This guide offers a checklist of questions and steps to help you feel ready for biopsy day.

    At a Glance: Key Preparation Areas

    • Understand the biopsy timeline in your cycle
    • Follow medication and monitoring instructions exactly
    • Confirm logistics with your clinic and lab
    • Prepare questions for your care team
    • Plan for results waiting time

    Understanding the PGT-A Biopsy Process

    PGT-A is performed on embryos created through IVF. Typically, embryos are cultured in the laboratory for several days until they reach the blastocyst stage. A biopsy involves removing a few cells from the outer layer of the embryo (trophectoderm), which will become the placenta. These cells are then sent for genetic analysis. The embryo is frozen while you wait for results.

    In Thailand, the biopsy is always performed by an embryologist in a specialized laboratory. You will not be present during the biopsy. Your role is to ensure that your embryos are developing normally and that the lab has everything it needs to proceed.

    Before Your Cycle: Questions to Ask Your Clinic

    Preparation begins before you start ovarian stimulation. Use this list to clarify details with your fertility clinic:

    • What is the exact day of embryo development when the biopsy will be performed?
    • Will the biopsy be done on day 5, day 6, or later? How does this affect the cycle?
    • How many embryos are expected to be biopsied? What happens if none reach the biopsy stage?
    • Which genetic testing laboratory will be used? Is it on-site or external?
    • How will the biopsy results be communicated to you and your doctor?
    • What are the costs for the biopsy and genetic analysis? Are there additional fees for freezing or shipping?
    • Are there any specific instructions for your partner or support person on biopsy day?

    Medication and Monitoring: Following Instructions

    Your clinic will provide a personalized medication plan for ovarian stimulation and, if applicable, for preparing your uterine lining. While the biopsy itself does not require special medication, your overall cycle timing depends on strict adherence to your protocol.

    • Take all medications at the same time each day as prescribed.
    • Attend all monitoring appointments (blood tests and ultrasounds) as scheduled.
    • Inform your clinic of any missed doses or side effects immediately.
    • Ask whether you need to adjust any medications on the day of egg retrieval or before the biopsy.

    Remember that the biopsy is performed on embryos in the lab, so your medication does not directly affect the biopsy procedure. However, your cycle coordination is essential for having embryos available for testing.

    Logistics on Biopsy Day

    Biopsy day is usually a routine day for you. You may not need to be at the clinic unless you have a scheduled appointment. However, it is wise to confirm the following:

    • Will you receive a phone call or message when the biopsy is completed?
    • Is there a specific time when you should be available?
    • Do you need to sign any consent forms before the biopsy?
    • How will you be informed if the biopsy cannot be performed (e.g., if embryos do not develop)?

    If you are traveling from abroad, ensure you have a local phone number or reliable internet connection for communication.

    What to Ask the Laboratory

    Even though you may not interact directly with the lab, you can ask your clinic to relay questions. Consider these points:

    • What is the laboratory’s experience with PGT-A biopsies?
    • How many cells are typically removed, and what is the success rate for obtaining a result?
    • What is the turnaround time for results?
    • Will the embryos be frozen immediately after biopsy? What is the survival rate after thawing?
    • Are there any additional tests recommended, such as PGT-M for a specific genetic condition?

    Preparing for Results and Next Steps

    After the biopsy, embryos are frozen while the genetic analysis is completed. The waiting period can be emotionally challenging. Plan ahead:

    • Ask your clinic how long results typically take (this varies by lab).
    • Discuss with your doctor how results will be interpreted and what options you have.
    • Consider counseling or support groups to manage anxiety during the wait.
    • Prepare questions about the number of normal embryos and what that means for your transfer plan.

    Your PGT-A Cycle Preparation Checklist

    Use this checklist to stay organized:

    • Confirm your clinic’s biopsy protocol and timeline.
    • Follow medication and monitoring instructions precisely.
    • Clarify costs and payment schedules.
    • Arrange travel and accommodation if coming from abroad.
    • Prepare a list of questions for your doctor and embryologist.
    • Plan for communication during the waiting period.
    • Discuss emotional support options with your partner or clinic.

    Understanding PGT-A Limitations

    PGT-A is a screening tool, not a guarantee. It can reduce the risk of transferring an embryo with an abnormal number of chromosomes, but it does not ensure a pregnancy or a healthy baby. Some embryos with normal results may still fail to implant, and other genetic or non-genetic factors can affect outcomes. Discuss the limitations and benefits with your doctor to make an informed decision.

    Next Steps

    Preparation for PGT-A biopsy in Thailand is mostly about clear communication and planning. By asking the right questions and following your clinic’s guidance, you can approach biopsy day with confidence. For more information, explore our PGT in Thailand guide, visit our patient guides, or check our FAQ section.

    Frequently asked questions

    Do I need to do anything special on the day of the PGT-A biopsy?

    No, the biopsy is performed in the laboratory on embryos. You typically do not need to be present. However, confirm with your clinic whether you need to be available for updates or if any consent forms are required.

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

    Turnaround times vary by laboratory. Ask your clinic for an estimated timeline. It can range from a few days to a couple of weeks, depending on the lab's workload and shipping if samples are sent externally.

    Can I choose not to have PGT-A?

    Yes, PGT-A is optional. Your doctor can explain the potential benefits and limitations based on your age, medical history, and number of embryos. You can decide whether to proceed after a thorough discussion.

    What happens if no embryos develop to the biopsy stage?

    If embryos do not reach the blastocyst stage, the biopsy cannot be performed. Your doctor will discuss options, which may include extended culture, additional cycles, or alternative treatments.

  • IVF for Women Over 40 in Thailand: Key Considerations

    Understanding IVF After 40

    If you are a woman over 40 considering IVF in Thailand, you likely have questions about your chances, the steps involved, and what you can do to prepare. This guide provides an overview of the medical and logistical considerations, with a focus on the potential role of preimplantation genetic testing (PGT). It is designed to help you have informed conversations with fertility specialists.

    Age is a significant factor in fertility, primarily because the quantity and quality of eggs decline as women get older. This can affect the number of eggs retrieved during an IVF cycle, the fertilization rate, and the likelihood of embryos developing normally. However, every woman is different, and a thorough evaluation by a fertility clinic is essential to understand your individual situation.

    At a Glance: Key Considerations

    • Pre-IVF workup: Comprehensive testing to assess ovarian reserve, uterine health, and overall well-being.
    • PGT-A: A genetic test that can screen embryos for chromosomal abnormalities, which are more common with advanced maternal age.
    • Donor eggs: A realistic option to consider if your own eggs are not producing viable embryos.
    • Clinic selection: Look for a clinic with experience in treating women over 40 and a transparent approach to counseling.

    Pre-IVF Workup: What to Expect

    Before starting an IVF cycle, your clinic will likely recommend a series of tests to evaluate your fertility potential. These may include:

    • Ovarian reserve testing: Blood tests (such as AMH and FSH) and an antral follicle count via ultrasound to estimate the number of eggs remaining.
    • Uterine evaluation: An ultrasound or hysteroscopy to check the uterine cavity for any abnormalities that could affect implantation.
    • Infectious disease screening: Routine blood tests for both partners.
    • Genetic carrier screening: Optional testing to identify if you or your partner carry genes for certain inherited conditions.

    This workup helps your doctor tailor your treatment plan and set realistic expectations. It is also a good time to discuss any chronic health conditions, such as high blood pressure or diabetes, that may need to be managed before and during pregnancy.

    The Role of PGT-A in IVF Over 40

    Preimplantation genetic testing for aneuploidy (PGT-A) is a technique that screens embryos for chromosomal abnormalities before transfer. Aneuploidy means having an abnormal number of chromosomes, which is a common cause of implantation failure and miscarriage. The risk of aneuploidy increases with maternal age, so PGT-A is often discussed as an option for women over 40.

    PGT-A involves taking a small sample of cells from a day-5 or day-6 embryo (blastocyst) and analyzing the DNA. The goal is to identify embryos with the correct number of chromosomes, which may have a higher chance of implanting and developing into a healthy pregnancy. However, it is important to understand that PGT-A is not a guarantee of success, and it does not test for all genetic conditions.

    Not all embryos will be suitable for biopsy, and some may not survive the process. Additionally, PGT-A results can be inconclusive or show mosaicism (a mix of normal and abnormal cells). Your clinic should explain the benefits, limitations, and costs of PGT-A so you can make an informed decision.

    Other Types of PGT

    In addition to PGT-A, there are other types of preimplantation genetic testing that may be relevant:

    • PGT-M (for monogenic disorders): This tests for specific single-gene diseases, such as cystic fibrosis or sickle cell anemia, when one or both partners are known carriers.
    • PGT-SR (for structural rearrangements): This is used when a partner has a chromosomal rearrangement, such as a translocation, which can increase the risk of miscarriage or chromosomal abnormalities in offspring.

    These tests are not routine for all patients and are only recommended when there is a specific medical indication. Your fertility specialist can advise whether PGT-M or PGT-SR is appropriate for your situation.

    Considering Donor Eggs

    For some women over 40, using donor eggs may be a realistic path to pregnancy. This is often recommended when a woman’s own eggs are unlikely to produce viable embryos, based on factors such as very low ovarian reserve or a history of poor embryo development.

    Donor egg IVF involves using eggs from a young, healthy donor, which are fertilized with your partner’s or a donor’s sperm. The resulting embryos are then transferred to your uterus. This option can significantly increase the chance of a live birth, but it involves complex medical, legal, and emotional considerations. It is important to discuss the process, including donor screening, legal agreements, and costs, with your clinic.

    Choosing a Clinic in Thailand

    When selecting an IVF clinic in Thailand, consider the following:

    • Experience with advanced maternal age: Ask how many patients over 40 the clinic treats and what their approach is.
    • Laboratory quality: Inquire about the embryology lab’s standards, including success rates for blastocyst culture and biopsy.
    • Counseling and support: Look for a clinic that offers psychological support and clear communication.
    • Transparency: The clinic should provide clear information about costs, success rates, and the risks and benefits of procedures like PGT-A.

    You may also want to ask about the availability of genetic counseling, which can help you interpret PGT results and make decisions.

    Questions to Ask Your Clinic

    Before committing to a clinic, consider asking these questions:

    • What tests will I need before starting IVF?
    • What is your experience with women over 40?
    • Do you recommend PGT-A for my age group? Why or why not?
    • What are the costs for IVF, PGT-A, and any additional procedures?
    • What is your policy on transferring embryos with inconclusive or mosaic results?
    • What support services do you offer for emotional and psychological well-being?

    Next Steps: Your Checklist

    1. Gather your medical records, including any previous fertility treatments.
    2. Research clinics and shortlist those that meet your criteria.
    3. Schedule a consultation to discuss your specific situation.
    4. Ask about the pre-IVF workup and any recommended genetic testing.
    5. Consider your options for donor eggs if applicable.
    6. Plan for the logistics of travel, accommodation, and time in Thailand.

    Remember, every IVF journey is unique. Take the time to gather information, ask questions, and make decisions that feel right for you.

    Frequently asked questions

    Is IVF over 40 possible in Thailand?

    Yes, IVF is possible for women over 40 in Thailand. However, success rates are generally lower compared to younger women due to age-related decline in egg quality and quantity. A thorough pre-IVF workup can help assess your individual chances.

    What is PGT-A and why is it recommended for women over 40?

    PGT-A is a genetic test that screens embryos for chromosomal abnormalities before transfer. Because the risk of aneuploidy increases with maternal age, PGT-A can help identify embryos with the correct number of chromosomes, potentially reducing the risk of miscarriage and increasing the chance of a successful pregnancy. However, it is not a guarantee and has limitations.

    Should I consider donor eggs if I am over 40?

    Donor eggs may be a recommended option if your own eggs are unlikely to produce viable embryos. This is often based on factors like very low ovarian reserve or poor embryo development in previous cycles. Discuss your specific situation with your fertility specialist to understand the potential benefits and considerations.

    What tests are included in a pre-IVF workup for women over 40?

    A pre-IVF workup typically includes ovarian reserve testing (AMH, FSH, antral follicle count), uterine evaluation, infectious disease screening, and possibly genetic carrier screening. These tests help your doctor tailor your treatment plan and set realistic expectations.

  • PGT-A and Egg Freezing in Thailand: What to Know

    Understanding PGT-A and Egg Freezing

    If you are considering egg freezing in Thailand, you may have heard about PGT-A (preimplantation genetic testing for aneuploidy). PGT-A is a test that checks embryos for the correct number of chromosomes. It is often used during IVF to help select embryos for transfer. But how does it work when eggs are frozen first? This guide explains the basics, the timing, and the limitations you should discuss with your clinic.

    At a Glance: Key Points

    • PGT-A is optional and not a guarantee of pregnancy or a healthy baby.
    • Testing is usually done on embryos, not on eggs directly.
    • Frozen eggs can be thawed, fertilized, and grown to the blastocyst stage before biopsy.
    • Timing of testing may affect your treatment plan and costs.
    • Discuss logistics, costs, and legal aspects with your clinic.

    How PGT-A Works with Frozen Eggs

    When you freeze eggs, they are stored until you are ready to use them. Later, the eggs are thawed and fertilized with sperm to create embryos. These embryos are typically cultured for about five to six days until they reach the blastocyst stage. At that point, a few cells are removed from the outer layer of the embryo (trophectoderm) for testing. This biopsy is sent to a genetics laboratory to analyze the chromosomes.

    PGT-A can identify embryos with the correct number of chromosomes (euploid) and those with an abnormal number (aneuploid). Aneuploid embryos may fail to implant or may lead to miscarriage. However, PGT-A does not guarantee a successful pregnancy or a healthy baby. It is a screening tool, not a diagnostic test for all genetic conditions.

    Timing of PGT-A on Frozen Eggs

    The timing of PGT-A is important. In a typical IVF cycle with fresh eggs, testing occurs after fertilization and embryo culture. With frozen eggs, the process is similar: eggs are thawed, fertilized, and cultured to blastocyst. The biopsy is then performed, and the embryos are usually frozen while waiting for results. This is called a freeze-all cycle.

    Some clinics may offer the option to test eggs before freezing, but this is less common and may not be as reliable. Most often, PGT-A is performed on embryos created from frozen eggs. The entire process—from thawing to biopsy—requires careful coordination between the fertility clinic and the genetics laboratory. Ask your clinic about their specific protocols and timelines.

    Potential Limitations of PGT-A on Frozen Eggs

    There are several limitations to consider. First, not all eggs will survive the thawing process. The survival rate can vary, and some eggs may not fertilize or develop into blastocysts. This means you may have fewer embryos available for testing than you might expect.

    Second, PGT-A is a screening test, not a guarantee. It can reduce the risk of transferring an embryo with an abnormal number of chromosomes, but it cannot detect all genetic problems. Also, a normal PGT-A result does not ensure a live birth.

    Third, the biopsy and freezing process may slightly reduce the viability of some embryos, although this is generally considered safe. Discuss the risks and benefits with your doctor.

    Questions to Ask Your Clinic

    Before deciding on PGT-A with frozen eggs, ask your clinic the following questions:

    • What is your experience with PGT-A on embryos from frozen eggs?
    • What is the expected survival rate for thawing my frozen eggs?
    • How many embryos typically reach the blastocyst stage for biopsy?
    • What is the turnaround time for PGT-A results?
    • How are embryos frozen after biopsy, and what is the success rate for thawing them later?
    • What are the costs for PGT-A, and are there additional fees for freezing and storage?
    • Are there any legal or regulatory considerations for genetic testing in Thailand?

    Next Steps: Your Checklist

    1. Consult with a fertility specialist to review your medical history and goals.
    2. Ask about the clinic’s protocols for egg freezing and PGT-A.
    3. Clarify costs, including medications, procedures, and genetic testing.
    4. Understand the legal and ethical aspects of genetic testing in Thailand.
    5. Consider genetic counseling to interpret PGT-A results and make informed decisions.

    Frequently asked questions

    Can PGT-A be done on frozen eggs directly?

    PGT-A is typically performed on embryos, not on eggs. Eggs are thawed, fertilized, and cultured to the blastocyst stage before a biopsy is taken. Some clinics may offer testing of polar bodies from eggs, but this is less common and may have limitations.

    How long does PGT-A take after egg freezing?

    The process involves thawing eggs, fertilization, embryo culture to blastocyst (about 5-6 days), biopsy, and then genetic analysis. Results may take several days to a few weeks, depending on the laboratory. Your clinic can provide a specific timeline.

    Does PGT-A guarantee a healthy baby?

    No. PGT-A screens for chromosomal abnormalities but does not guarantee a successful pregnancy or a healthy baby. It can reduce the risk of miscarriage due to aneuploidy, but other factors also affect outcomes.

    What are the risks of PGT-A on frozen eggs?

    Risks include the possibility that some eggs may not survive thawing, embryos may not develop to the biopsy stage, and the biopsy itself may slightly affect embryo viability. Discuss these risks with your clinic.

    Is PGT-A mandatory for egg freezing in Thailand?

    No, PGT-A is optional. It is a personal choice based on your medical history, age, and preferences. Your clinic can help you decide if it is appropriate for you.
