What Is the Typical Timeline for IVF with PGT in Thailand?

Understanding the IVF with PGT Timeline

IVF with preimplantation genetic testing (PGT) is a multi-stage process that typically takes several weeks from start to finish. For international patients planning treatment in Thailand, understanding the general timeline helps with travel arrangements, work leave, and financial planning. However, every patient’s journey is unique, and actual timelines vary based on individual medical factors, clinic protocols, and laboratory schedules. This guide provides a general overview; you must confirm all details directly with your chosen clinic.

At a Glance: Key Phases

• Pre-treatment phase: Initial consultation, medical assessments, and preparation (1–4 weeks before travel).
• Ovarian stimulation: Daily injections for 10–14 days, with monitoring appointments every 1–3 days.
• Egg retrieval: A minor surgical procedure, followed by 1–2 days of rest.
• Fertilization and embryo culture: 5–6 days to reach blastocyst stage.
• PGT biopsy and analysis: 2–4 weeks for genetic testing results.
• Embryo transfer: A brief procedure, typically in a subsequent menstrual cycle if using frozen embryos.
• Post-transfer monitoring: Pregnancy test approximately 10–14 days after transfer.

Step 1: Pre-Treatment Consultation and Preparation

Before traveling to Thailand, you will usually have an initial consultation with the fertility specialist, often via video call. During this consultation, the doctor reviews your medical history, discusses treatment options, and may order preliminary tests (e.g., blood work, semen analysis, ultrasound). Some clinics require these tests to be done in your home country and sent ahead. This phase can take 1–4 weeks, depending on how quickly you complete the required assessments.

Step 2: Ovarian Stimulation (10–14 Days)

Once you arrive in Thailand and are cleared to start, ovarian stimulation begins. You will self-administer daily hormone injections (FSH, LH, or similar) for approximately 10–14 days. During this period, you will visit the clinic every 1–3 days for blood tests and ultrasounds to monitor follicle growth. The clinic will adjust your medication dose as needed. Most patients stay in Thailand for the entire stimulation phase.

Step 3: Egg Retrieval (1 Day)

When follicles reach the appropriate size, you will receive a trigger injection to finalize egg maturation. Egg retrieval is performed under sedation or anesthesia about 36 hours later. The procedure takes 20–30 minutes, and you can usually go home after a few hours of recovery. Most clinics recommend resting for the remainder of the day and avoiding strenuous activity for 24–48 hours.

Step 4: Fertilization and Embryo Culture (5–6 Days)

After retrieval, eggs are fertilized with sperm (via ICSI, which is standard with PGT). Embryos are cultured in the laboratory for 5–6 days until they reach the blastocyst stage. During this time, you may return to your accommodation and wait for updates from the clinic. Some patients choose to travel home during this waiting period, but many stay in Thailand to be available for transfer.

Step 5: PGT Biopsy and Analysis (2–4 Weeks)

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 to a genetics laboratory for analysis. PGT can detect chromosomal abnormalities (PGT-A) or specific genetic disorders (PGT-M). The analysis typically takes 2–4 weeks, depending on the type of testing and the laboratory’s workload. During this time, you can return home and await results.

Step 6: Embryo Transfer (1 Day)

Once PGT results are available, you will discuss with your doctor which embryos are suitable for transfer. If you are using frozen embryos, the transfer usually occurs in a subsequent menstrual cycle. You will need to return to Thailand for the transfer, which is a quick procedure (10–15 minutes) without anesthesia. The clinic will prescribe medications to prepare your uterine lining, which may take 2–4 weeks before the transfer date.

Step 7: Post-Transfer Monitoring (10–14 Days)

After the transfer, you will wait 10–14 days before taking a pregnancy test (blood test for hCG). Some clinics may schedule additional monitoring appointments. If the test is positive, you may continue medication support and have an early ultrasound before returning home. If negative, you can discuss next steps with your doctor.

Total Time in Thailand

For the initial cycle (stimulation through egg retrieval and embryo culture), most patients plan to stay in Thailand for 3–4 weeks. The PGT waiting period (2–4 weeks) is typically spent at home. The frozen embryo transfer requires a separate trip of about 1–2 weeks, depending on your lining preparation protocol. Some patients may combine both trips if they have flexible schedules, but this is less common.

Factors That Can Affect the Timeline

• Individual response to medication: Some patients require longer stimulation or different protocols.
• Embryo development: Not all embryos reach blastocyst stage; this can affect biopsy timing.
• PGT laboratory schedule: Analysis time varies by lab and test type.
• Clinic protocols: Some clinics have specific days for transfers or may batch cycles.
• Medical or personal reasons: Health issues, cycle cancellation, or scheduling conflicts can delay treatment.

Questions to Ask Your Clinic

• What is the estimated timeline for my specific treatment plan?
• How long should I plan to stay in Thailand for each phase?
• When will PGT results be available, and how will I receive them?
• What is the typical wait time between egg retrieval and frozen embryo transfer?
• Are there any factors that could delay my timeline?

Next Steps

• Schedule an initial consultation with a fertility clinic in Thailand.
• Complete any required pre-treatment tests and share results with the clinic.
• Discuss your travel plans and timeline with the clinic coordinator.
• Plan your accommodation and leave from work based on the estimated timeline.
• Confirm all costs, including PGT analysis, medications, and additional procedures.

Frequently asked questions

How long does the entire IVF with PGT process take from start to finish?

The full process, including initial consultation, ovarian stimulation, egg retrieval, embryo culture, PGT analysis, and frozen embryo transfer, typically spans 2–4 months. This includes waiting periods between cycles and the time needed for genetic testing.

Can I go home during the PGT waiting period?

Yes, most patients return home after egg retrieval and embryo freezing while waiting for PGT results (2–4 weeks). You will need to return to Thailand for the frozen embryo transfer in a subsequent cycle.

How long do I need to stay in Thailand for the egg retrieval cycle?

For the stimulation, egg retrieval, and embryo culture phase, plan to stay in Thailand for approximately 3–4 weeks. This includes daily monitoring during stimulation and recovery after retrieval.

Is the timeline the same for PGT-A and PGT-M?

PGT-M (for single gene disorders) often requires additional development of a genetic probe, which can take several weeks or months before the cycle begins. PGT-A (for aneuploidy) typically has a shorter analysis time of 2–3 weeks. Confirm with your clinic.

What happens if my embryos don't develop to blastocyst stage?

If embryos do not reach the blastocyst stage by day 6, they may not be suitable for biopsy or transfer. Your doctor will discuss alternative options, such as a fresh transfer on day 3 (without PGT) or a new cycle.
