Planning an IVF cycle with preimplantation genetic testing (PGT) in Thailand involves several stages over multiple weeks. This guide outlines the general steps and timeline, from initial consultation to embryo transfer, and highlights what you need to confirm with your chosen clinic.
Understanding the IVF with PGT Timeline
For international patients considering IVF with preimplantation genetic testing (PGT) in Thailand, understanding the overall timeline is essential for planning travel, work leave, and family arrangements. While each clinic and individual case varies, a full cycle typically spans several weeks to a few months. This article provides a general overview of the stages involved and the factors that can affect the duration.
At a Glance: Key Stages
- Initial Consultation & Preparation: 1–4 weeks (can be done remotely)
- Ovarian Stimulation: 10–14 days
- Egg Retrieval: 1 day (outpatient procedure)
- Fertilization & Embryo Culture: 5–6 days
- Embryo Biopsy & PGT: 2–4 weeks for results
- Frozen Embryo Transfer (FET): 1 day (after results, typically in a subsequent cycle)
Note: The total time from start to transfer can range from 6 to 12 weeks, depending on clinic protocols, PGT turnaround, and whether a fresh or frozen transfer is performed.
Stage 1: Initial Consultation and Preparation
Before traveling, most clinics offer an initial remote consultation via video call. During this session, you will discuss your medical history, previous treatments, and the recommended protocol. You may be asked to provide recent test results (e.g., hormone levels, semen analysis) or complete additional tests upon arrival. This stage can take 1–4 weeks, depending on how quickly you complete required screenings and receive approval from the clinic.
Stage 2: Ovarian Stimulation
Once you arrive in Thailand, ovarian stimulation typically begins on day 2 or 3 of your menstrual cycle. You will self-administer hormone injections daily for about 10–14 days. During this period, you will visit the clinic every 2–3 days for blood tests and ultrasound scans to monitor follicle growth. The stimulation phase requires you to be in Thailand for the entire duration.
Stage 3: Egg Retrieval
When follicles reach the appropriate size, a trigger injection is given, and egg retrieval is scheduled 36 hours later. The procedure is performed under sedation or anesthesia and takes about 20–30 minutes. You can usually return to your accommodation the same day. Recovery is typically quick, but you may need to rest for a day or two.
Stage 4: Fertilization and Embryo Culture
After retrieval, eggs are fertilized using ICSI (intracytoplasmic sperm injection) to maximize fertilization rates. Embryos are cultured in the laboratory for 5–6 days until they reach the blastocyst stage. During this time, you may return home if you are planning a frozen embryo transfer (FET) in a later cycle.
Stage 5: Embryo Biopsy and PGT
On day 5 or 6, a few cells are biopsied from each blastocyst. The embryos are then vitrified (frozen) while the biopsy samples are sent for genetic testing. PGT results typically take 2–4 weeks, depending on the type of test (PGT-A for aneuploidy, PGT-M for monogenic disorders, or PGT-SR for structural rearrangements). During this waiting period, you do not need to remain in Thailand.
Stage 6: Frozen Embryo Transfer (FET)
Once PGT results are available, you will discuss which embryos are suitable for transfer. The transfer is usually performed in a subsequent menstrual cycle, after preparing the uterine lining with medications. This involves another trip to Thailand, typically lasting 1–2 weeks. The transfer procedure itself is quick and painless, similar to a Pap smear. After transfer, you may need to stay for a few days before returning home.
Factors That Can Affect the Timeline
- Clinic protocols: Some clinics may recommend a “freeze-all” approach, while others may consider fresh transfer if PGT results are available quickly.
- PGT type and lab: Turnaround time varies by testing laboratory and whether you are testing for multiple conditions.
- Embryo development: Not all embryos reach blastocyst stage; this can affect the number of embryos available for biopsy.
- Personal health factors: Ovarian response, hormone levels, and uterine conditions can influence stimulation length and transfer timing.
- Legal and administrative requirements: Some countries require specific documentation for embryo transport or genetic testing; confirm with your clinic and local authorities.
Questions to Ask Your Clinic
- What is the estimated timeline from initial consultation to embryo transfer for my specific case?
- How long do I need to stay in Thailand for each stage?
- Can initial consultations and follow-ups be done remotely?
- What is the typical turnaround time for PGT results?
- Are there any additional tests or procedures that could extend the timeline?
- What is the clinic’s policy on fresh versus frozen transfer after PGT?
Next Steps for Planning
- Research clinics in Thailand that offer IVF with PGT and have experience with international patients.
- Schedule a remote consultation to discuss your timeline and travel plans.
- Confirm the required duration of stay and any necessary documentation (e.g., visas, medical records).
- Plan for flexibility in your schedule, as individual responses to treatment can vary.
- Arrange accommodation near the clinic for the stimulation and retrieval phases.
Remember that every IVF cycle is unique. The timeline provided here is a general guide; your actual experience may differ. Always confirm specific details with your chosen clinic and medical team.
Frequently asked questions
How long do I need to stay in Thailand for an IVF with PGT cycle?
The required stay depends on the stage. For ovarian stimulation and egg retrieval, you typically need to be in Thailand for 2–3 weeks. If you plan a frozen embryo transfer after PGT results, you will need a separate trip of about 1–2 weeks. Some clinics may allow you to combine stages, so confirm with your clinic.
Can I do the initial consultation remotely?
Yes, many clinics in Thailand offer remote consultations via video call for international patients. This allows you to discuss your medical history and receive a preliminary treatment plan before traveling.
How long does PGT testing take?
PGT results typically take 2–4 weeks, depending on the type of test and the laboratory. PGT-A (aneuploidy screening) may be faster, while PGT-M (monogenic disorders) can take longer. Your clinic will provide an estimated timeline.
Do I need to stay in Thailand while waiting for PGT results?
No, you do not need to remain in Thailand during the PGT waiting period. Embryos are frozen and stored at the clinic. You can return home and come back for the transfer once results are available.
What if my embryos don't develop to blastocyst stage?
Not all embryos reach the blastocyst stage (day 5–6). If no embryos are suitable for biopsy, the cycle may end without transfer. Your doctor will discuss options, such as a different protocol or additional testing.
