IVF with PGT in Thailand: A Step-by-Step Guide for International Patients

Introduction

For many international patients, Thailand has become a leading destination for IVF combined with preimplantation genetic testing (PGT). The country offers advanced reproductive technology, experienced specialists, and a supportive environment for those traveling abroad for fertility treatment. However, navigating the process from abroad requires careful planning and a clear understanding of each step.

This guide provides a general overview of the IVF with PGT journey in Thailand, from your initial inquiry to the embryo transfer. Because every patient’s situation is unique, we highlight the questions you should ask your chosen clinic and the decisions you will need to make. The goal is to help you feel informed and prepared, while recognizing that your clinic will provide the specific medical advice and timelines tailored to you.

Step 1: Initial Consultation and Medical Review

Your journey begins with an initial consultation, which can often be done remotely via video call. During this meeting, you will discuss your medical history, fertility goals, and whether IVF with PGT is appropriate for your situation. The clinic will request your medical records, including previous fertility treatments, genetic screening results, and any relevant health information.

Key questions to ask:

• What tests do I need to complete before starting treatment?
• Can I send my medical records in advance, or do I need to be tested in Thailand?
• What is the estimated timeline from consultation to embryo transfer?
• How do you handle genetic counseling for PGT?

After reviewing your information, the clinic will propose a treatment plan. This plan will include the medications you will need, the expected number of monitoring visits, and the schedule for egg retrieval, fertilization, biopsy, and transfer. Keep in mind that the exact timeline depends on your individual response to medications and the results of genetic testing.

Step 2: Travel Planning and Visa Considerations

Once you have a treatment plan, you can start planning your travel. International patients typically need to stay in Thailand for a minimum period that covers the initial monitoring, egg retrieval, and embryo transfer. The total duration can vary, so it is essential to confirm with your clinic.

Travel checklist:

• Check visa requirements for your nationality. Many countries can enter Thailand for medical treatment on a tourist visa or a medical visa. Confirm the latest rules with the Royal Thai Embassy or Consulate in your country.
• Arrange accommodation near the clinic. Many clinics offer recommendations or partnerships with nearby hotels or serviced apartments.
• Plan for a companion if needed. Some patients prefer to have a partner or friend accompany them for support.
• Consider travel insurance that covers medical treatment abroad.

Important: Visa policies and travel restrictions can change. Always verify current requirements with official sources before booking.

Step 3: Ovarian Stimulation and Monitoring

After arriving in Thailand, you will begin ovarian stimulation. This involves daily hormone injections for about 10–14 days to encourage your ovaries to produce multiple eggs. During this time, you will visit the clinic regularly for blood tests and ultrasound scans to monitor follicle growth. The clinic will adjust your medication dose as needed.

This phase requires you to be in Thailand, as monitoring is frequent. Most clinics schedule appointments in the morning, leaving you free for the rest of the day. It is a good time to rest, eat well, and manage stress.

What to confirm with your clinic:

• How many monitoring visits are typically needed?
• What are the clinic’s hours for monitoring?
• Can I store my medications at the clinic or my accommodation?

Step 4: Egg Retrieval (Follicle Aspiration)

When your follicles reach the optimal size, you will be scheduled for egg retrieval. This is a minor surgical procedure performed under sedation or anesthesia. It usually takes about 20–30 minutes. You will need to rest at the clinic for a few hours afterward and should arrange for someone to take you back to your accommodation.

After the procedure, you may experience mild cramping or bloating, which typically resolves within a day or two. Your clinic will provide post-retrieval instructions and pain relief if needed.

Key points:

• You must not eat or drink for several hours before the procedure (follow your clinic’s fasting instructions).
• Plan to take it easy for the rest of the day.
• Your partner or sperm donor will need to provide a semen sample on the day of retrieval, or you may have arranged for frozen sperm to be shipped to the clinic.

Step 5: Fertilization and Embryo Culture

After egg retrieval, the eggs are fertilized in the laboratory using either conventional insemination or intracytoplasmic sperm injection (ICSI). ICSI is commonly used in PGT cycles to ensure fertilization and to avoid contamination from sperm cells that could interfere with genetic testing.

The resulting embryos are cultured in the lab for 5–6 days until they reach the blastocyst stage. At this point, the embryologist will assess the embryos for quality and prepare them for biopsy.

Step 6: Trophectoderm Biopsy (PGT)

PGT involves removing a few cells from the outer layer of the blastocyst (the trophectoderm, which will become the placenta). This biopsy is performed on day 5 or 6 of embryo development. The cells are then sent to a genetics laboratory for analysis.

There are different types of PGT:

• PGT-A (aneuploidy screening): Checks for the correct number of chromosomes.
• PGT-M (monogenic disorders): Tests for specific genetic conditions.
• PGT-SR (structural rearrangements): Detects chromosomal rearrangements.

Your clinic will explain which type is recommended based on your medical history and genetic concerns.

Timing note: The biopsy results typically take 7–14 days, sometimes longer depending on the laboratory. This means that after egg retrieval, you may need to return home and come back for the embryo transfer in a subsequent cycle, or you may stay in Thailand if the timeline allows. Discuss this with your clinic to plan your travel accordingly.

Step 7: Embryo Freezing and Waiting for Results

After biopsy, the embryos are vitrified (frozen) and stored while the genetic analysis is performed. Freezing is standard practice because the biopsy results are not available in time for a fresh transfer in the same cycle.

During the waiting period, you can return home if you wish. The clinic will contact you with the results once they are ready. You will then schedule a follow-up consultation to discuss the findings and plan the next steps.

Questions to ask:

• How long does it take to receive PGT results?
• Will the clinic provide genetic counseling to help interpret the results?
• What are the storage fees for frozen embryos?

Step 8: Preparing for Embryo Transfer

Once you have your PGT results and have selected a euploid (chromosomally normal) embryo for transfer, you will prepare your uterus for implantation. This usually involves a frozen embryo transfer (FET) cycle, where you take medications to build up your uterine lining. The preparation can take 2–4 weeks, depending on your cycle and the clinic’s protocol.

You will need to return to Thailand for the transfer. The clinic will monitor your lining with ultrasounds and blood tests to determine the optimal day for transfer.

Travel planning: The FET cycle typically requires a stay of about 1–2 weeks, but confirm with your clinic as protocols vary.

Step 9: Embryo Transfer

The embryo transfer is a simple procedure that does not require anesthesia. A thin catheter is used to place the embryo into your uterus. You can usually go home shortly after and resume normal activities, though many clinics recommend resting for a day or two.

After the transfer, you will be given medications (such as progesterone) to support the uterine lining. About 10–14 days later, you will have a pregnancy test to see if the transfer was successful.

Note: The clinic may advise you to stay in Thailand until the pregnancy test, or you may be able to return home and have the test done locally. Discuss this with your doctor.

Step 10: Follow-Up and Next Steps

If the pregnancy test is positive, the clinic will provide instructions for ongoing care, including when to have an ultrasound to confirm a viable pregnancy. You may need to continue medications for several weeks. If the test is negative, your doctor will discuss options for future cycles, including using another frozen embryo or starting a new stimulation cycle.

Regardless of the outcome, the clinic will offer support and guidance for your next steps.

Summary of the Timeline

The entire process from initial consultation to embryo transfer can take several months, especially when factoring in travel and the waiting period for PGT results. A typical timeline might look like this:

• Remote consultation and medical review: 1–2 weeks
• Travel to Thailand and start of stimulation: 2–3 weeks
• Egg retrieval and recovery: 1 week
• Embryo culture and biopsy: 1 week
• PGT results: 1–2 weeks (may overlap with travel home)
• FET preparation: 2–4 weeks
• Embryo transfer and pregnancy test: 2 weeks

This is a general guide. Your actual timeline will depend on your individual circumstances, clinic protocols, and the type of PGT performed.

Important Considerations for International Patients

• Language and communication: Ensure the clinic has English-speaking staff or provides translation services.
• Legal and ethical aspects: Thailand has regulations regarding IVF and PGT. Ask your clinic about the legal framework, especially regarding embryo disposition and genetic testing.
• Costs: IVF with PGT involves multiple fees, including medications, lab work, biopsy, genetic analysis, and storage. Request a detailed cost breakdown from your clinic.
• Support network: Consider joining online forums or support groups for international patients undergoing IVF in Thailand.

Frequently asked questions

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

The required stay depends on your treatment plan. Typically, you may need to be in Thailand for 2–3 weeks for the initial stimulation and egg retrieval, and then return for a separate stay of 1–2 weeks for the frozen embryo transfer. The waiting period for PGT results (7–14 days) can often be spent at home. Confirm the exact timeline with your clinic.

Can I do PGT on all embryos?

PGT is performed on embryos that reach the blastocyst stage (day 5–6). Not all embryos may be suitable for biopsy. Your clinic will assess embryo quality and discuss which embryos can be tested.

What is the difference between PGT-A and PGT-M?

PGT-A screens for an abnormal number of chromosomes (aneuploidy), which is a common cause of implantation failure and miscarriage. PGT-M tests for specific single-gene disorders, such as cystic fibrosis or thalassemia. Your doctor will recommend the appropriate test based on your medical history.

Do I need a visa for medical treatment in Thailand?

Many nationalities can enter Thailand on a tourist visa for medical treatment, but requirements vary. Some patients may apply for a medical visa. Check with the Royal Thai Embassy or Consulate in your country for the latest information.

What happens if no embryos are suitable for transfer?

If no euploid embryos are available after PGT, your doctor will discuss alternative options, such as using donor eggs, donor embryos, or considering a new stimulation cycle. Genetic counseling can help you understand the results and make informed decisions.
