Thailand PGT IVF FAQ: Answers for International Patients

PGT (preimplantation genetic testing) is a laboratory step added to an IVF cycle in which a few cells are sampled from an embryo and tested before transfer. In Thailand, PGT is offered at some fertility clinics, but availability, the specific tests used, and the rules around them can differ between providers. PGT can give information about certain chromosome or gene findings, but it cannot guarantee a pregnancy, a live birth, or a healthy child. This FAQ answers the questions international patients ask most often, and points to what you should confirm directly with a treating clinic.

At a glance

• PGT is an add-on to IVF, not a separate treatment.
• Different PGT types answer different questions; the right one depends on your situation.
• PGT results are probabilistic, not guarantees.
• Clinics in Thailand vary in which tests they offer and how they report results.
• Costs, timelines, and paperwork are clinic-specific and should be confirmed in writing.

What is PGT, and how is it different from IVF?

IVF involves stimulating the ovaries, retrieving eggs, fertilising them in the laboratory, and transferring an embryo to the uterus. PGT is an extra laboratory step performed on embryos before transfer. A small number of cells are removed from the embryo (usually at the blastocyst stage), and those cells are tested for specific chromosome or gene findings.

PGT does not change the IVF process itself. It adds a testing phase, which can extend the time to transfer because embryos may need to be frozen while results are awaited.

What are the main types of PGT?

PGT is an umbrella term. The three commonly described types are:

• PGT-A (aneuploidy): looks at the number of chromosomes in the embryo. It can identify embryos with an abnormal number of chromosomes, which may be associated with implantation failure or miscarriage.
• PGT-M (monogenic): looks for a specific inherited condition caused by a single gene, when a known familial variant has been identified.
• PGT-SR (structural rearrangements): looks at chromosome structure, for people who carry a balanced translocation or similar rearrangement.

Which type is relevant depends on your medical history, your family history, and what your treating clinician recommends. PGT is not a general screen for all possible health issues.

Who might consider PGT?

PGT is usually discussed in specific situations, such as:

• A known inherited condition in the family.
• Recurrent pregnancy loss.
• Repeated implantation failure after IVF.
• Advanced maternal age, where chromosome abnormalities in embryos are more common.
• A known chromosome rearrangement in one partner.

This is not a complete list, and eligibility is a clinical decision. A clinic will assess whether PGT is appropriate for you based on your history and their laboratory capabilities.

What can PGT tell you, and what can it not tell you?

PGT can provide information about the specific chromosomes or genes being tested. It cannot:

• Guarantee that an embryo will implant.
• Guarantee a live birth.
• Guarantee that a child will be free of all health conditions.
• Detect every possible genetic or chromosomal issue.
• Predict how a child will develop.

PGT results are one part of the picture. Your clinician will interpret them alongside other factors.

How do international patients usually plan PGT IVF in Thailand?

Planning typically involves several stages. Exact steps vary by clinic, so treat this as a general framework:

1. Initial enquiry: contact the clinic, share your medical history, and ask whether PGT is offered and which types.
2. Records review: the clinic reviews your history and may request additional tests before confirming a plan.
3. Consultation: discuss the proposed protocol, the PGT type, and what the results can and cannot show.
4. Travel and treatment: plan your stay around monitoring, egg retrieval, and any follow-up. Some clinics coordinate remote monitoring with your local doctor.
5. Testing and transfer: embryos are tested, results are reported, and a transfer is planned if appropriate.

Timelines depend on your cycle, the clinic’s laboratory schedule, and whether embryos are frozen. Ask for a written outline of the expected sequence.

What should you ask a clinic before committing?

These questions help you compare clinics and avoid surprises:

• Which PGT types do you offer, and what does each test look for?
• What is your laboratory’s experience with PGT, and how are results reported?
• What are the total costs, including IVF, PGT, medication, freezing, storage, and any follow-up?
• What is the expected timeline from consultation to transfer?
• What happens if no embryos are suitable for transfer after testing?
• What support do you provide for international patients (language, coordination, remote monitoring)?
• What documents do I need to bring, and are there any legal or regulatory requirements I should know about?

Get answers in writing where possible, and ask for clarification on anything that is unclear.

What about costs and paperwork?

Costs for PGT IVF in Thailand vary widely depending on the clinic, the type of PGT, the number of embryos tested, medication, and whether you need additional services. There is no single standard price. Ask for an itemised quote that separates IVF, PGT, medication, freezing, storage, and any administrative fees.

Paperwork requirements also vary. Clinics may ask for identification, medical records, and consent forms. Legal or regulatory requirements for international patients can change, so confirm current requirements with the clinic and, if needed, with the relevant authority in Thailand. Do not rely on general online summaries for legal or visa conclusions.

What are the limits and uncertainties of PGT?

PGT is a screening tool, not a diagnostic guarantee. Some embryos may be classified as inconclusive, and some may be mosaic (having a mix of cells with different chromosome numbers). How a clinic reports and interprets these findings matters. Ask how your clinic handles inconclusive or mosaic results, and what that means for transfer decisions.

Also remember that PGT adds cost and time, and it may reduce the number of embryos available for transfer. For some patients, the trade-off is worthwhile; for others, it may not be. This is a personal decision to discuss with your clinician.

Next steps

If you are considering PGT IVF in Thailand, start by clarifying your own medical questions, then contact clinics to compare their PGT offerings, costs, and international patient support. Keep a written record of what you are told. For more general guidance, see our international patients page, browse the FAQ, read our guides, or contact us with your questions.

Frequently asked questions

Is PGT IVF in Thailand available to international patients?

Some clinics in Thailand offer PGT to international patients, but availability varies by clinic and by the type of PGT. You should confirm directly with the clinic whether they offer the specific test you need and whether they accept international patients for that service.

How much does PGT IVF cost in Thailand?

Costs vary widely and depend on the clinic, the type of PGT, the number of embryos tested, medication, and other services. There is no standard price. Ask each clinic for an itemised quote that separates IVF, PGT, medication, freezing, storage, and administrative fees.

Does PGT guarantee a healthy baby?

No. PGT can provide information about specific chromosomes or genes, but it cannot guarantee a pregnancy, a live birth, or a child free of all health conditions. It is one part of the IVF process, and results should be interpreted by your clinician.

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

The length of stay depends on your treatment protocol, monitoring schedule, and whether embryos are frozen while awaiting test results. Ask your clinic for a written timeline so you can plan travel and accommodation.

What documents do I need for PGT IVF in Thailand?

Document requirements vary by clinic and can change. Clinics may ask for identification, medical records, and consent forms. Confirm current requirements directly with the clinic and, if needed, with the relevant Thai authority. Do not rely on general online summaries for legal or visa conclusions.
