At a glance
A plain-English walkthrough of the PGT IVF process in Thailand for international patients, from first consultation to embryo transfer, with the questions to confirm directly with your clinic.
PGT IVF in Thailand usually follows a predictable sequence: consultation and records review, pre-treatment testing, ovarian stimulation and monitoring, egg retrieval, fertilisation and embryo culture, embryo biopsy and genetic testing, then a later frozen embryo transfer. For international patients, the main difference is that some steps can be done remotely in your home country, while others require you to be in Thailand. The exact order, timing and requirements depend on your medical situation and the clinic you choose, so treat this as a planning map rather than a fixed schedule.
At a glance
- PGT is an add-on to IVF, not a separate treatment pathway.
- Some early steps can often be arranged remotely; stimulation, retrieval and transfer generally require travel.
- PGT results usually mean embryos are frozen and transferred in a later cycle.
- Timelines vary widely between patients and clinics, so ask for a personalised estimate.
- Confirm costs, documents, medication plans and legal requirements directly with your clinic and relevant authorities.
What PGT adds to a standard IVF cycle
In vitro fertilisation (IVF) involves stimulating the ovaries, collecting eggs, fertilising them in a laboratory, and transferring an embryo to the uterus. Preimplantation genetic testing (PGT) is an additional laboratory step in which a small number of cells are removed from an embryo and tested. There are different types of PGT, and which one may be relevant depends on your history and your clinician’s assessment.
Because testing takes time, embryos are typically frozen after biopsy and transferred in a separate cycle. This is one reason the overall PGT IVF process can span more than one trip to Thailand. For a broader overview of IVF in the country, see IVF in Thailand and PGT in Thailand.
The step-by-step process for international patients
Step 1: Initial consultation and records review
Most clinics begin with a remote or in-person consultation. You will usually be asked about your medical and fertility history, previous treatments, medications, and any relevant test results. This is the stage to clarify whether PGT is appropriate for your situation, which type may be considered, and what the clinic needs from you before you travel.
Ask how consultations are conducted, what language support is available, and who your main point of contact will be. If you are comparing clinics, the treatment process page can help you frame consistent questions.
Step 2: Pre-treatment testing and preparation
Before stimulation, you and sometimes your partner may need blood tests, ultrasound scans, or other investigations. Some of these can often be done locally and shared with the clinic; others may need to be repeated in Thailand. The clinic will tell you which results it accepts and how recent they need to be.
This is also when medication plans are usually discussed. Do not start, stop or change any medication based on general information online. Your treating clinician should give you personalised instructions.
Step 3: Ovarian stimulation and monitoring
Stimulation involves medication to encourage multiple eggs to mature. During this phase you will have monitoring appointments, usually ultrasound scans and sometimes blood tests, to track how your ovaries are responding. Monitoring frequency varies from person to person.
For international patients, the key planning question is where monitoring will happen. Some clinics coordinate part of the monitoring with a local clinic in your home country, while others prefer you to be in Thailand for this phase. Confirm this early, because it affects your travel dates.
Step 4: Egg retrieval
When your clinician decides the timing is right, a trigger injection is usually given, followed by egg retrieval. Retrieval is typically a short procedure performed under sedation or anaesthesia. You will normally need someone to accompany you afterwards and should plan a rest day.
Ask the clinic what the retrieval day involves, how long you should stay in Thailand around it, and what follow-up you should expect.
Step 5: Fertilisation and embryo culture
Collected eggs are fertilised in the laboratory, and any resulting embryos are cultured for several days. The laboratory team monitors development and decides, with your clinician, which embryos are suitable for biopsy and testing. Not every egg fertilises, and not every embryo reaches the stage where testing is possible. This is a normal part of IVF and not a reflection of anything you did.
Step 6: Embryo biopsy and PGT
During biopsy, a small sample of cells is taken from the embryo. The sample is then tested, and the embryos are usually frozen while results are pending. The time needed for results depends on the test and the laboratory, so ask your clinic for an estimate rather than relying on general figures.
Your clinic should explain what the results can and cannot tell you, and how they will be used in decisions about transfer. PGT does not guarantee a pregnancy or a healthy child.
Step 7: Results review and transfer planning
Once results are available, you will usually have a consultation to discuss them and plan the next steps. If you are proceeding with a transfer, the clinic will explain how the lining of the uterus will be prepared and when you need to be in Thailand. Some patients need more than one cycle or additional appointments, so build flexibility into your plans.
Step 8: Embryo transfer and aftercare
Embryo transfer is usually a short procedure and often does not require anaesthesia. After transfer, you will be given instructions about medication, activity and when to take a pregnancy test. Ask how results will be communicated and what follow-up is recommended if you return home.
Planning your travel around the process
Because PGT IVF can involve more than one visit, it helps to think in phases rather than a single trip. The table below outlines typical travel considerations, but exact durations must come from your clinic.
| Phase | Where it may happen | What to confirm |
|---|---|---|
| Consultation and records review | Often remote | Accepted tests, language support, point of contact |
| Pre-treatment testing | Home country or Thailand | Which results are accepted and how recent they must be |
| Stimulation and monitoring | Usually Thailand, sometimes partly local | Whether local monitoring is coordinated and how |
| Egg retrieval | Thailand | Required stay, escort, recovery time |
| Biopsy, testing and freezing | Thailand (laboratory) | Expected result timeframe and how results are shared |
| Transfer cycle | Thailand | Preparation protocol, travel dates, medication plan |

Questions to ask your clinic before you commit
- Which type of PGT are you recommending for my situation, and why?
- Which steps can be done remotely, and which require me to be in Thailand?
- What is a realistic timeline for someone with my history, including possible delays?
- What costs should I expect, and what is not included?
- What documents do I need to prepare, and are there any legal or consent requirements I should know about?
- How will you communicate results, and who do I contact with questions?
- What happens if no embryos are suitable for transfer?
Next-step checklist
- Gather your medical records and previous test results.
- Book a consultation and ask about remote options.
- Confirm which tests are needed and where they can be done.
- Ask for a written outline of the process, costs and travel windows.
- Check passport, visa and entry requirements with the relevant authority.
- Plan flexible travel dates and consider travel insurance.
- Keep a single point of contact at the clinic for coordination.
A note on uncertainty
IVF and PGT involve many variables. Response to medication, embryo development and test results cannot be predicted with certainty. A good clinic will explain ranges and possibilities rather than promises. Use this guide to organise your questions, and rely on your treating team for decisions about your care.
Frequently asked questions
How long does the PGT IVF process take in Thailand?
There is no single timeline. It depends on your protocol, how your body responds, laboratory processing times and whether you need more than one cycle. Ask your clinic for a personalised estimate and build in flexibility for travel and waiting periods.
Can I do any part of the PGT IVF process from my home country?
Some clinics coordinate remote consultations and part of the monitoring with a local clinic, but policies vary. Confirm which steps can be done locally, which tests are accepted, and when you must be in Thailand.
Why are embryos frozen before PGT results are available?
Genetic testing takes time, so embryos are typically frozen after biopsy and transferred in a later cycle. This allows results to be reviewed before planning a transfer.
What should I confirm about costs and documents?
Ask for a written breakdown of what is included and excluded, and a list of required documents. Legal, visa and entry requirements should be checked with the relevant authority, as they can change.
Does PGT guarantee a successful pregnancy?
No. PGT provides additional information about embryos, but it cannot guarantee implantation, pregnancy, live birth or child health. Your clinician can explain what the results can and cannot tell you.
