Understanding the IVF Timeline in Thailand
For international patients, planning an IVF cycle in Thailand involves coordinating medical appointments, travel, and time off work. While each clinic and individual case is unique, the general process follows a sequence of phases. This guide outlines the typical steps and highlights where flexibility is needed. Always confirm exact timelines and requirements with your chosen clinic.
Phase 1: Initial Consultation and Preparation
Before traveling, you will have an initial consultation, often via video call. The doctor reviews your medical history, previous tests, and may request new ones. This phase includes:
- Review of fertility history and previous treatments
- Blood tests (hormone levels, infectious disease screening)
- Semen analysis (if applicable)
- Ultrasound assessment of the uterus and ovaries
- Discussion of treatment plan and estimated timeline
Some clinics require these tests to be done in Thailand, while others accept recent results from your home country. Confirm which documents are needed and how far in advance you should send them.
Phase 2: Ovarian Stimulation (Approximately 10–14 Days)
Once you arrive in Thailand, ovarian stimulation begins. You will self-administer hormone injections daily to stimulate multiple follicles to grow. The clinic monitors your progress with blood tests and ultrasounds every 1–3 days. The duration depends on your response to medication. At the end of this phase, a trigger injection is given to mature the eggs.
What to Expect During Stimulation
- Daily injections (usually subcutaneous)
- Frequent clinic visits for monitoring
- Possible side effects: bloating, mild discomfort, mood changes
- Adjustments to medication dose based on response
Phase 3: Egg Retrieval (1 Day)
Egg retrieval is a minor surgical procedure performed under sedation or anesthesia. It takes about 20–30 minutes. You will need to rest at the clinic for a few hours afterward. Most patients recover within a day. Plan for a light day after the procedure.
Phase 4: Fertilization and Embryo Culture (5–6 Days)
After retrieval, eggs are fertilized with sperm (IVF or ICSI). Embryos are cultured in the lab for 5–6 days until they reach the blastocyst stage. The clinic will update you on fertilization rates and embryo development. If you plan to have preimplantation genetic testing (PGT), this occurs after biopsy on day 5 or 6.
Phase 5: Preimplantation Genetic Testing (PGT) – Optional (2–4 Weeks)
PGT involves biopsying a few cells from each embryo and sending them to a genetics lab for analysis. Results typically take 2–4 weeks. During this time, embryos are frozen (vitrified) and stored. If you are not doing PGT, you can proceed to a fresh transfer.
Important Considerations for PGT
- PGT adds significant time to the overall timeline
- You may need to return to Thailand for a frozen embryo transfer (FET) after results
- Discuss with your clinic whether PGT is recommended for your situation
Phase 6: Embryo Transfer (1 Day)
For a fresh transfer, the embryo is transferred on day 5 or 6 after retrieval. For a frozen transfer (FET), the uterus is prepared with hormones over 2–4 weeks before the transfer. The transfer itself is a quick procedure similar to a pap smear, usually without anesthesia. You can resume normal activities the next day.
Phase 7: Pregnancy Test (10–14 Days After Transfer)
About 10–14 days after transfer, a blood test (beta-hCG) is done to check for pregnancy. If positive, you may need to stay in Thailand for an early ultrasound scan (around 6–7 weeks) or follow up with your local doctor.
Total Time Commitment: What to Plan For
The minimum stay in Thailand for a fresh IVF cycle without PGT is approximately 3–4 weeks. With PGT and a frozen transfer, you may need two separate trips: one for retrieval (2–3 weeks) and another for transfer (1–2 weeks), with a gap of several weeks in between. However, some clinics offer remote monitoring or flexible scheduling. Confirm the exact duration with your clinic.
Possible Delays and How to Prepare
- Unexpected poor response to stimulation may cancel the cycle
- Embryo development may not reach blastocyst stage
- PGT results may take longer than expected
- Uterine lining may not be optimal for transfer, requiring postponement
- Clinic or lab scheduling issues
Build flexibility into your travel plans. Consider refundable flights and accommodation. Discuss contingency plans with your clinic.
Questions to Ask Your Clinic
- What is the typical timeline for a patient like me?
- What tests can be done before I arrive?
- How many monitoring visits are required per week?
- What is the policy if the cycle is cancelled?
- How long are embryos stored, and what are the costs?
- What are the requirements for a second trip if doing PGT?
Conclusion
An IVF cycle in Thailand typically spans several weeks, with the possibility of multiple trips if genetic testing is involved. Each step requires careful planning and communication with your clinic. By understanding the general timeline and preparing for potential delays, you can make informed decisions about your travel and time off. Always verify specific details with your treating clinic.
Frequently asked questions
How long do I need to stay in Thailand for IVF?
The minimum stay for a fresh IVF cycle without PGT is about 3–4 weeks. With PGT and a frozen transfer, you may need two separate trips: 2–3 weeks for retrieval and 1–2 weeks for transfer, with a gap of several weeks. Confirm exact durations with your clinic.
Can I do some tests before traveling to Thailand?
Some clinics accept recent test results from your home country, while others require tests in Thailand. Ask your clinic which tests can be done beforehand and which must be repeated upon arrival.
What happens if my cycle is cancelled?
Cancellation can occur due to poor response to medication or other medical reasons. Discuss your clinic's cancellation policy, including any refunds or credits, before starting treatment.
How long does PGT take?
PGT results typically take 2–4 weeks. During this time, embryos are frozen. You may need to return to Thailand for a frozen embryo transfer after results are available.
Can I do a fresh transfer if I want PGT?
No, PGT requires embryo biopsy and analysis, which takes weeks. Embryos must be frozen and transferred in a subsequent cycle. Discuss the timeline with your clinic.
