PGT IVF Process in Thailand: A Step-by-Step Guide for International Patients

PGT IVF in Thailand follows the same broad clinical sequence used worldwide: ovarian stimulation, egg retrieval, fertilisation in the laboratory, embryo culture, a biopsy of a few cells from each suitable embryo, genetic testing of those cells, and a later transfer of an embryo back to the uterus. For international patients, the main difference is logistics: you are coordinating travel, accommodation, monitoring and communication across borders. The exact number of visits, the tests used, the timing of each step and the cost all depend on your individual case and on the clinic you choose, so treat any general overview as a planning framework rather than a personal treatment plan.

At a glance

• PGT is a laboratory add-on to an IVF cycle, not a separate treatment.
• The cycle usually involves a stimulation phase, a retrieval day, a laboratory phase and a transfer phase.
• Some clinics transfer a tested embryo in a later cycle rather than immediately after retrieval.
• International patients typically need to plan travel around monitoring, retrieval and transfer windows.
• Which PGT test is appropriate, and whether it is appropriate at all, is a medical decision for your treating clinician.
• Costs, documents, visa rules and timelines must be confirmed directly with the clinic and relevant authorities.

What PGT adds to a standard IVF cycle

Preimplantation genetic testing (PGT) is an umbrella term for laboratory tests performed on cells removed from an embryo during IVF. The general aim is to give the clinical team additional information about that embryo before transfer. Different PGT categories look at different things, and the terminology is often used loosely online. Your clinic should explain which test it is recommending for your situation, what the test can and cannot tell you, and what the laboratory’s reporting process looks like.

It is important to understand that PGT is not a guarantee of pregnancy, live birth or a healthy child. It is one piece of information among many, and your clinician will weigh it alongside your history, age, embryo development and other factors. If a clinic presents PGT as a certainty, that is a reason to ask more questions, not fewer.

The PGT IVF process, step by step

The sequence below is a general framework. Your actual pathway may combine, reorder or repeat some steps depending on your protocol and your clinic’s laboratory arrangements.

Step 1: Initial enquiry and records review

Most international patients begin with an online enquiry. The clinic will usually ask for relevant medical history, previous fertility treatment records, and any recent test results. This stage is about whether IVF with PGT is a reasonable option to discuss, and what further investigations might be needed before a protocol can be proposed. Ask how records should be sent, whether translations are needed, and who your main point of contact will be.

Step 2: Consultation and pre-treatment planning

A consultation, often by video for international patients, is where the clinical team reviews your history and outlines possible approaches. This is the point to clarify which PGT category is being considered and why, what the laboratory’s general workflow is, and what monitoring can be done locally versus in Thailand. You should also ask about the clinic’s consent process and how results are communicated.

Step 3: Ovarian stimulation and monitoring

Stimulation involves medication to encourage multiple follicles to develop. Monitoring usually includes blood tests and ultrasound scans. Some clinics allow part of this monitoring to be done in your home country, with results shared, before you travel. The number of monitoring visits, the medication protocol and the criteria for triggering ovulation are all individual medical decisions. Do not rely on general timelines found online; ask your clinic what your specific schedule is likely to involve.

Step 4: Trigger and egg retrieval

When the follicles are considered ready, a trigger injection is timed, and egg retrieval is scheduled. Retrieval is typically a short procedure performed under sedation or anaesthesia, depending on the clinic. You will usually need someone to accompany you afterwards. Ask the clinic about fasting instructions, medication changes, recovery expectations and when you can travel after the procedure.

Step 5: Fertilisation and embryo culture

Retrieved eggs are combined with sperm in the laboratory, either through standard insemination or intracytoplasmic sperm injection (ICSI), depending on the clinical indication. Embryos are then cultured for several days. The laboratory monitors development and decides which embryos are suitable for biopsy. This is a laboratory decision based on embryo development, not something you can predict in advance.

Step 6: Embryo biopsy

At an appropriate stage of development, a small number of cells are removed from each suitable embryo. This is a delicate laboratory procedure. Not every embryo will be suitable for biopsy, and some cycles may end with no embryos to test. Ask your clinic how it handles this scenario and what it means for your options.

Step 7: Genetic testing and reporting

The biopsied cells are analysed using the laboratory’s chosen method. Results are usually reported as a category rather than a simple yes or no, and the meaning of each category should be explained by your clinician. Turnaround time varies by laboratory and test type. Ask how results will be shared, who will explain them, and whether a genetic counselling appointment is available.

Step 8: Embryo transfer or cryopreservation

Depending on your protocol and the results, an embryo may be transferred in a later cycle, or embryos may be cryopreserved for future use. Transfer is usually a short procedure. If you are travelling home between retrieval and transfer, you will need to plan a second trip or arrange local monitoring. Ask the clinic how it coordinates transfer timing for international patients.

Step 9: After transfer and follow-up

After transfer, there is usually a waiting period before a pregnancy test. Your clinic will explain when and how to test, what medications to continue, and who to contact with questions. If the cycle does not result in pregnancy, ask about a review consultation and what information from the cycle can inform future planning.

How the international patient workflow usually differs

For patients travelling to Thailand, the clinical steps are broadly the same, but the coordination is different. Common differences include:

• Remote preparation: consultations, records review and some pre-treatment testing may happen before you travel.
• Split monitoring: some scans and blood tests may be done locally, with results shared with the clinic in Thailand.
• Two-trip patterns: some patients travel once for retrieval and again for transfer, while others stay for a longer period.
• Language and consent: consent forms and explanations may be in English or translated, so ask how understanding is confirmed.
• Continuity of contact: time zones can affect response times, so ask how urgent questions are handled.

These are planning categories, not fixed rules. Your clinic should confirm what applies to your case.

Questions to ask your clinic before committing

Use these as a starting point. Write down the answers so you can compare clinics consistently.

1. Which PGT category are you recommending for my situation, and why?
2. What does the test look for, and what can it not tell me?
3. How many embryos typically need to be available for testing to be worthwhile in cases like mine?
4. What happens if no embryos are suitable for biopsy or transfer?
5. Which parts of monitoring can be done in my home country?
6. How many trips to Thailand are usually needed, and roughly when?
7. What is the total cost range, and what is included or excluded?
8. What documents, translations or consents will I need?
9. Who explains the genetic results, and is counselling available?
10. What are the clinic’s arrangements for urgent questions across time zones?

Planning checklist for international patients

• Gather previous fertility and medical records in a shareable format.
• Ask about translation requirements for documents and consent forms.
• Confirm the clinic’s process for remote consultations and record transfer.
• Ask how monitoring can be split between your home country and Thailand.
• Clarify the likely number and timing of trips, without assuming fixed durations.
• Request a written cost outline that distinguishes clinic fees, laboratory fees, medication and travel.
• Ask about accommodation options near the clinic and typical recovery time before flying.
• Check your own travel insurance and any visa or entry requirements with the relevant authority.
• Decide in advance how you want results communicated and to whom.
• Keep a single written record of what each clinic tells you.

What this guide cannot tell you

This overview deliberately avoids exact prices, success rates, medication doses, legal conclusions and clinic-specific promises, because those depend on your individual situation and on current rules that change over time. Your treating clinic and the relevant authorities are the only reliable sources for those details. Use this page to understand the shape of the process and to prepare better questions, then confirm everything directly before you commit to travel or treatment.

Frequently asked questions

How long does the PGT IVF process take in Thailand?

The clinical sequence from stimulation to transfer usually spans several weeks, but the exact duration depends on your protocol, your response to medication, laboratory turnaround for genetic testing, and whether transfer happens in the same cycle or a later one. Because these factors vary so much between patients, ask your clinic for a personalised estimate rather than relying on a general figure.

Do I need to stay in Thailand for the whole PGT IVF cycle?

Not necessarily. Some clinics allow part of the monitoring to be done in your home country, with results shared remotely, and some patients travel twice rather than staying continuously. The right arrangement depends on your protocol and your clinic's requirements, so confirm the expected travel pattern directly with your treating team.

Does PGT guarantee a healthy baby or a successful pregnancy?

No. PGT provides additional laboratory information about an embryo, but it does not guarantee pregnancy, live birth or a healthy child. Your clinician should explain what the test can and cannot indicate in your specific situation, and how the results fit into the wider decision about transfer.

What should I ask about the laboratory doing the genetic testing?

Ask which testing method is used, how results are categorised and reported, typical turnaround times, how the laboratory handles inconclusive results, and who at the clinic will explain the report to you. If genetic counselling is available, ask how to access it.

How do I compare costs between clinics without exact prices online?

Request a written cost outline from each clinic that separates consultation fees, monitoring, medication, laboratory and PGT fees, transfer, cryopreservation and any administrative charges. Ask what is excluded and whether prices can change during treatment. Because published figures are often incomplete or outdated, a written, itemised quote is more useful than a headline number.
