Planning your IVF cycle with PGT in Thailand? This guide outlines the typical timeline from initial consultation to frozen embryo transfer, including waiting periods and travel planning tips.
Understanding the IVF with PGT Timeline in Thailand
For international patients considering IVF with preimplantation genetic testing (PGT) in Thailand, understanding the timeline is essential for planning travel, work, and accommodation. While every patient’s journey is unique, the general process follows a predictable sequence of steps. This guide provides a realistic overview of the timeline from initial consultation to embryo transfer, highlighting where individual variation occurs and what you must confirm directly with your chosen clinic.
Step 1: Initial Consultation and Preparation
Before you travel, you will typically have an initial consultation with your chosen fertility clinic. This can often be done via video call. During this consultation, the doctor reviews your medical history, previous fertility treatments, and any relevant test results. You may be asked to complete certain blood tests, semen analysis, or other assessments in your home country before traveling. The clinic will also discuss your treatment plan, including the estimated timeline and any medications you will need.
What to confirm with your clinic: Whether initial tests can be done abroad or must be repeated in Thailand, and how far in advance you should schedule your consultation.
Step 2: Cycle Start and Ovarian Stimulation
Once you are cleared to proceed, your IVF cycle begins. This usually starts on day 2 or 3 of your menstrual cycle. You will begin daily hormone injections to stimulate your ovaries to produce multiple eggs. Ovarian stimulation typically lasts 10 to 14 days, but this can vary based on your individual response. During this time, you will have regular monitoring appointments (blood tests and ultrasounds) at the clinic to track follicle growth and adjust medication as needed.
Travel planning tip: Plan to arrive in Thailand a few days before your expected cycle start to allow for any last-minute tests and to settle in. The stimulation phase requires frequent clinic visits, so choose accommodation near the clinic.
Step 3: Egg Retrieval (Oocyte Pick-Up)
When the follicles are mature, you will receive a trigger injection to finalize egg maturation. Egg retrieval is performed approximately 36 hours later under light sedation. The procedure itself takes about 20–30 minutes, and you will need to rest at the clinic for a few hours afterward. Most patients can return to their accommodation the same day. You should plan to take it easy for the remainder of the day.
What to confirm with your clinic: The exact timing of the trigger shot and retrieval, and any specific post-retrieval instructions.
Step 4: Fertilization and Embryo Culture
After retrieval, the eggs are fertilized with sperm (either from a partner or donor) using ICSI (intracytoplasmic sperm injection) to maximize fertilization rates. The resulting embryos are cultured in the laboratory for 5 to 6 days until they reach the blastocyst stage. During this time, you will not need to be at the clinic daily, but you may have a follow-up appointment to discuss the number of eggs retrieved and fertilization results.
Step 5: Embryo Biopsy and Vitrification
Once embryos reach the blastocyst stage, a biopsy is performed. A few cells are gently removed from the trophectoderm (the part that becomes the placenta) for genetic testing. The biopsied embryos are then vitrified (frozen) and stored while the PGT analysis is conducted. The biopsy itself does not require your presence, but you will be informed of the number of embryos biopsied.
Step 6: PGT Analysis (Waiting Period)
The biopsied cells are sent to a genetics laboratory for PGT. The analysis typically takes 2 to 4 weeks, depending on the type of testing (PGT-A for aneuploidy, PGT-M for monogenic disorders, or PGT-SR for structural rearrangements). During this waiting period, you can return home or continue traveling. The clinic will contact you with the results once they are available.
Travel planning tip: Many patients choose to return home during this waiting period and come back to Thailand for the frozen embryo transfer. Discuss with your clinic whether you can coordinate the transfer timing remotely.
Step 7: Frozen Embryo Transfer (FET)
If you have at least one genetically normal embryo, you can proceed with a frozen embryo transfer. This requires preparing your uterine lining with medications (estrogen and progesterone) over approximately 2 to 4 weeks. The transfer itself is a quick procedure similar to a Pap smear, usually performed without anesthesia. After the transfer, you will wait about 10 to 14 days before taking a pregnancy test.
What to confirm with your clinic: The exact protocol for endometrial preparation, the timing of the transfer relative to your cycle, and whether you need to be in Thailand for the entire preparation phase or just the transfer day.
Summary of the Overall Timeline
| Step | Approximate Duration | Patient Presence Required |
|---|---|---|
| Initial consultation | 1–2 days (can be remote) | Optional (remote) |
| Ovarian stimulation | 10–14 days | Yes, daily monitoring |
| Egg retrieval | 1 day | Yes |
| Embryo culture & biopsy | 5–6 days | Minimal (follow-up) |
| PGT analysis | 2–4 weeks | No (can be remote) |
| Frozen embryo transfer preparation | 2–4 weeks | Varies by clinic |
| Transfer and pregnancy test | 1 day + 10–14 days wait | Yes for transfer |
Note: The total time from cycle start to transfer can range from 6 to 12 weeks, depending on the PGT waiting period and your individual response. Many patients plan a stay of 3–4 weeks for the initial phase (stimulation through retrieval and biopsy), then return for a second stay of 2–4 weeks for the transfer.
Factors That Can Affect Your Timeline
- Individual response to medication: Some patients require longer stimulation or may need to cancel a cycle if response is poor.
- Embryo development: Not all embryos reach the blastocyst stage; this can affect the number of embryos available for biopsy.
- PGT type and lab workload: PGT-M or PGT-SR may take longer than PGT-A. Confirm the expected turnaround time with your clinic.
- Clinic schedule and availability: Some clinics have waiting lists or limited slots for certain procedures.
- Legal and documentation requirements: International patients may need to provide additional documents (e.g., marriage certificate, consent forms). Confirm requirements well in advance.
Travel Planning Tips for International Patients
- Visa: Check Thailand’s visa requirements for your nationality. Medical treatment visas may be available; confirm with the Thai embassy or your clinic.
- Accommodation: Choose a place near your clinic, especially during the stimulation phase when daily monitoring is needed. Many clinics offer packages with nearby hotels.
- Medication: Arrange for medication delivery or purchase at a local pharmacy. Some medications require refrigeration.
- Support person: Consider bringing a partner or friend for emotional support and assistance after retrieval.
- Insurance: Check if your health insurance covers any part of IVF or complications. Most plans do not, but it’s worth verifying.
- Communication: Ensure you have a reliable way to contact the clinic (phone, email, messaging app).
