At a glance
Planning an IVF cycle with PGT in Thailand involves several stages over multiple weeks. This guide outlines the general sequence from initial consultation to embryo transfer, helping international patients prepare for travel and treatment.
If you are considering IVF with preimplantation genetic testing (PGT) in Thailand, understanding the timeline helps you plan your travel, work, and personal commitments. While every patient’s journey is unique, a full cycle generally spans several weeks and involves distinct phases. This guide outlines the typical sequence of events so you know what to expect and what questions to ask your clinic.
At a Glance: Key Phases of an IVF with PGT Cycle
- Initial consultation and preparation: 1–4 weeks before starting treatment
- Ovarian stimulation: Approximately 10–14 days
- Egg retrieval: One day, followed by 1–2 days of rest
- Embryo culture and biopsy: 5–7 days after retrieval
- PGT analysis: Typically 2–4 weeks
- Embryo transfer: Usually in a subsequent menstrual cycle
Phase 1: Initial Consultation and Preparation
Before you travel, you will 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, discusses your goals, and outlines the recommended treatment plan. You may be asked to complete certain tests (e.g., blood work, semen analysis) either at home or after arrival in Thailand. The clinic will also provide instructions on any medications to start before your cycle.
What to confirm with your clinic:
- Which tests are required and whether they can be done in your home country
- Timing of medication start relative to your menstrual cycle
- Estimated duration of your stay in Thailand
Phase 2: Ovarian Stimulation
Once you arrive in Thailand and your menstrual cycle begins, you will start daily hormone injections to stimulate your ovaries to produce multiple eggs. This phase typically lasts 10–14 days. You will visit the clinic every few days for blood tests and ultrasound scans to monitor follicle growth. The clinic will adjust your medication dose as needed.
Travel note: You must remain in Thailand during this entire phase, as monitoring is frequent.
Phase 3: Egg Retrieval
When the follicles reach the appropriate size, you will receive a trigger injection to mature the eggs. The egg retrieval procedure is performed under sedation or light anesthesia and takes about 20–30 minutes. You can usually go home the same day after a short recovery period. Most patients feel well enough to resume light activities the next day.
Phase 4: Embryo Culture and Biopsy
After retrieval, the eggs are fertilized with sperm (via ICSI) in the laboratory. The resulting embryos are cultured for 5–7 days until they reach the blastocyst stage. At that point, a few cells are gently removed from each embryo for genetic testing (PGT). This biopsy does not harm the embryo. The embryos are then frozen (vitrified) while awaiting test results.
Phase 5: PGT Analysis
The biopsied cells are sent to a genetics laboratory for analysis. The time required for PGT results varies by the type of testing (PGT-A for aneuploidy, PGT-M for monogenic disorders, PGT-SR for structural rearrangements) and the laboratory’s workload. Typically, results are available within 2–4 weeks. During this waiting period, you may return home if you wish.
Phase 6: Embryo Transfer
Once the PGT results are received, your doctor will discuss which embryos are suitable for transfer. The transfer is usually scheduled in a subsequent natural or medicated menstrual cycle, depending on your individual circumstances. The transfer procedure itself is quick and does not require anesthesia. After the transfer, you will wait approximately 10–14 days before a pregnancy test.
Important: The timing of the transfer can vary based on your cycle, the clinic’s schedule, and whether you need additional preparation (e.g., endometrial lining assessment). Confirm the expected timeline with your clinic.
Total Time in Thailand
For the initial stimulation and retrieval, you should plan to be in Thailand for at least 3–4 weeks. If you choose to stay for the transfer in the same trip, the total stay may be longer, depending on when your next cycle begins. Many patients prefer to return home after retrieval and come back for the transfer once PGT results are ready. Discuss the best option with your clinic based on your schedule and preferences.
Questions to Ask Your Clinic
- What is the estimated timeline from start to transfer for my specific case?
- How long do I need to stay in Thailand for each phase?
- Can I travel home between egg retrieval and embryo transfer?
- How long do PGT results typically take at your affiliated laboratory?
- What is the process for scheduling the transfer after results are available?
Next Steps
- Research fertility clinics in Thailand and schedule initial consultations.
- Ask about required tests and whether they can be done before travel.
- Plan your travel and accommodation with flexibility for monitoring appointments.
- Discuss medication costs and logistics with your clinic.
Frequently asked questions
How long does the entire IVF with PGT cycle take from start to embryo transfer?
The full process typically spans 6–10 weeks, including initial consultation, ovarian stimulation (10–14 days), egg retrieval, embryo culture and biopsy (5–7 days), PGT analysis (2–4 weeks), and embryo transfer in a subsequent cycle. Exact timing varies by individual and clinic.
Can I go home during the PGT waiting period?
Yes, many patients return home after egg retrieval and come back to Thailand for the embryo transfer once PGT results are ready. Confirm with your clinic whether this is suitable for your treatment plan.
Do I need to stay in Thailand for the entire cycle?
You need to be in Thailand for the stimulation and monitoring phase (about 2 weeks) and for the egg retrieval (1 day). The transfer may be done in a separate trip. Discuss the recommended schedule with your clinic.
How long does PGT testing take?
PGT results typically take 2–4 weeks, depending on the type of test and the laboratory. Your clinic can provide a more specific estimate.
What factors can affect the timeline?
Factors include your ovarian response to stimulation, the number of embryos biopsied, the type of PGT, laboratory workload, and your menstrual cycle timing for the transfer. Always confirm the expected timeline with your treating clinic.
