IVF with PGT in Thailand: A Realistic Timeline for International Patients

Understanding the IVF with PGT Timeline

Planning an IVF cycle with preimplantation genetic testing (PGT) as an international patient involves multiple stages, each with its own time requirements. While every clinic and individual case differs, understanding the general flow helps you prepare for travel, work leave, and financial planning. This guide outlines the typical phases and highlights what you need to confirm directly with your chosen clinic.

Phase 1: Initial Consultation and Preparation (1–3 Months Before Travel)

Before traveling to Thailand, you will need to complete an initial consultation, usually via video call. During this consultation, the clinic reviews your medical history, fertility status, and any previous treatments. They will also discuss the PGT process, including which genetic conditions can be tested.

You will likely need to undergo baseline fertility testing locally, such as blood work (AMH, FSH) and a semen analysis (if applicable). Some clinics may request additional tests like infectious disease screening or genetic carrier screening. These results help the doctor create a personalized treatment plan.

Key questions to ask your clinic:

• What tests do I need to complete before traveling?
• How long are my test results valid?
• Do you require any specific documentation or medical records?

Phase 2: Travel and Initial Monitoring (1–2 Weeks in Thailand)

Once your treatment plan is set, you will travel to Thailand. The first few days involve an initial monitoring appointment, where the clinic performs an ultrasound and blood tests to confirm your cycle is ready to start. This typically occurs on day 2–3 of your menstrual cycle.

If you are using an egg donor or frozen eggs, the timeline may differ. For donor egg cycles, the donor’s cycle is synchronized with yours, and you may need to travel closer to the transfer date.

Travel considerations:

• Check current entry requirements, visa rules, and any health-related protocols (e.g., vaccination or testing).
• Plan for a minimum stay of 2–4 weeks, but confirm with your clinic as individual protocols vary.
• Arrange accommodation near the clinic for easy access to appointments.

Phase 3: Ovarian Stimulation and Egg Retrieval (10–14 Days)

Ovarian stimulation involves daily hormone injections for about 10–14 days to encourage multiple follicles to develop. During this period, you will visit the clinic every 2–3 days for blood tests and ultrasounds to monitor follicle growth. The clinic will adjust your medication doses as needed.

When the follicles reach the appropriate size, you will receive a trigger injection to mature the eggs. Egg retrieval is a minor surgical procedure performed under sedation, usually lasting 20–30 minutes. You can go home the same day but should plan for rest afterward.

Recovery note: Most women feel well enough to resume normal activities within 1–2 days, but avoid strenuous exercise for about a week.

Phase 4: Fertilization, Embryo Culture, and Biopsy (5–7 Days)

After retrieval, the eggs are fertilized using ICSI (intracytoplasmic sperm injection) to maximize fertilization rates. The resulting embryos are cultured in the lab for 5–6 days until they reach the blastocyst stage. At this point, a biopsy is performed: a few cells are removed from the trophectoderm (the part that becomes the placenta) for genetic testing.

The biopsy is a delicate procedure that does not harm the embryo. The embryos are then vitrified (frozen) while awaiting PGT results.

Phase 5: PGT Analysis and Results (2–4 Weeks)

The biopsied cells are sent to a genetics laboratory for analysis. PGT can screen for chromosomal abnormalities (PGT-A) or specific genetic disorders (PGT-M). The turnaround time for results is typically 2–4 weeks, but this can vary depending on the lab and the type of testing.

During this waiting period, you can return home if you wish. The clinic will inform you of the results, including which embryos are genetically normal (euploid) and suitable for transfer.

Important: The number of normal embryos cannot be guaranteed. Discuss with your clinic the possibility of having no transferable embryos and what options are available.

Phase 6: Frozen Embryo Transfer (FET) Preparation (2–4 Weeks)

Once you have a normal embryo, you will prepare for a frozen embryo transfer (FET). This involves taking medications (estrogen and progesterone) to prepare your uterine lining for implantation. The preparation typically takes 2–4 weeks, during which you may need to travel back to Thailand for monitoring or follow local instructions if your clinic allows remote monitoring.

The transfer itself is a simple procedure similar to a Pap smear, usually painless, and you can go home the same day. After the transfer, you will continue progesterone support for about 10–12 days until a pregnancy test.

Phase 7: Pregnancy Test and Follow-Up (10–14 Days Post-Transfer)

Approximately 10–14 days after the transfer, you will have a blood test (beta-hCG) to determine if implantation occurred. If positive, the clinic will schedule follow-up ultrasounds to confirm a viable pregnancy. You can usually return home after the first positive test, but some clinics recommend staying until the first ultrasound (around 6–7 weeks gestation).

Summary Timeline Overview

Note: Durations are estimates. Your clinic will provide a personalized calendar.

Factors That Can Affect Your Timeline

• Cycle type: Fresh vs. frozen donor eggs, or using your own eggs.
• PGT type: PGT-M for single gene disorders may take longer than PGT-A.
• Embryo development: Not all embryos reach blastocyst stage; some may arrest earlier.
• Clinic protocols: Some clinics use a “freeze-all” approach, while others may attempt fresh transfer if PGT is not needed.
• Personal health: Response to medications, uterine lining thickness, and other medical factors.

Planning Your Stay: What to Confirm with Your Clinic

Because every clinic has its own protocols and timelines, it is essential to ask specific questions before booking travel:

• What is the estimated total time I need to be in Thailand for the initial cycle?
• Do I need to stay for the entire stimulation and retrieval, or can I travel after the trigger shot?
• How long after retrieval will the biopsy be performed, and when are embryos frozen?
• What is the typical turnaround time for PGT results from your lab?
• Can I do FET preparation remotely, or must I return to Thailand for monitoring?
• What is the minimum recommended stay after transfer?
• Are there any mandatory waiting periods or quarantine requirements currently in effect?

Additional Considerations for International Patients

Visa and Travel Documents

Thailand offers visa exemptions or visa-on-arrival for many nationalities for short stays. However, medical treatment may require a different visa category. Check with the Thai embassy or consulate in your country for the most current requirements. Your clinic may provide a letter of invitation for a medical visa.

Health Insurance and Emergency Coverage

Ensure your travel insurance covers medical treatment abroad, including IVF-related complications. Some clinics offer packages that include insurance, but confirm the details.

Language and Communication

Most international clinics in Thailand have English-speaking coordinators. Clarify how you will receive updates (email, phone, patient portal) and who to contact in case of emergency.

Costs and Payment

IVF with PGT costs vary widely. Request a detailed breakdown of fees, including consultation, medications, lab work, PGT, embryo freezing, and transfer. Ask about payment methods and refund policies if a cycle is canceled.

Final Thoughts

Planning an IVF with PGT cycle in Thailand requires careful coordination, but understanding the timeline helps reduce stress. Remember that each journey is unique, and flexibility is key. Always confirm all details directly with your treating clinic and relevant authorities before making travel arrangements.

Frequently asked questions

How long do I need to stay in Thailand for IVF with PGT?

The minimum stay is typically 2–4 weeks for the initial cycle (stimulation, retrieval, and embryo culture). However, you may need to return for a frozen embryo transfer later. Confirm with your clinic for a personalized schedule.

Can I go home while waiting for PGT results?

Yes, most patients return home during the 2–4 week waiting period for PGT results. The clinic will contact you with results and discuss next steps.

Do I need a medical visa for IVF in Thailand?

Visa requirements depend on your nationality. Many countries have visa exemption or visa-on-arrival for short stays, but for medical treatment, a medical visa may be recommended. Check with the Thai embassy or your clinic.

What happens if no embryos are suitable for transfer after PGT?

If no euploid embryos are available, your doctor will discuss options such as a new cycle, using donor eggs, or other alternatives. This possibility should be discussed before starting treatment.

How soon after a failed transfer can I try again?

Your doctor will advise based on your individual situation. Typically, you may need to wait for one or two menstrual cycles before attempting another transfer.
