Planning IVF in Thailand? Learn the realistic timeline from initial online consultation to embryo transfer, including cycle length, PGT waiting period, and factors that affect your total stay.
Understanding the IVF Timeline in Thailand
For international patients, one of the most common questions is: How long does IVF take in Thailand from first consultation to embryo transfer? The answer depends on several factors, including the type of cycle (fresh or frozen), whether you are using your own eggs or donor eggs, and whether you plan to do preimplantation genetic testing (PGT).
In general, the entire process can take anywhere from 2 to 6 weeks of physical presence in Thailand, plus additional time for initial online consultations and preparation before you travel. This article provides a realistic timeline to help you coordinate your travel and accommodation.
Phase 1: Initial Consultation and Preparation (Before Travel)
Before you arrive in Thailand, you will typically have one or more online consultations with your chosen fertility clinic. During these consultations, you will discuss your medical history, review any previous test results, and receive instructions for preparing your body for the cycle.
Timeline: This phase can take anywhere from a few days to several weeks, depending on how quickly you can gather medical records and complete any required tests (such as blood work or semen analysis) in your home country. Some clinics may also request that you start taking birth control pills or other medications to synchronize your cycle before travel.
Key point: The initial consultation does not require you to be in Thailand. You can complete this step from home.
Phase 2: Arrival and Cycle Start (Days 1–3 of Menstrual Cycle)
Once you have been cleared to start treatment, you will travel to Thailand. Most clinics ask you to arrive on Day 1 or Day 2 of your menstrual cycle. On arrival, you will have a baseline ultrasound and blood test to confirm that your ovaries are ready for stimulation.
Timeline: You will need to be in Thailand from Day 1 of your cycle. The exact date depends on your natural cycle or, if you are using birth control pills, the withdrawal bleed.
Phase 3: Ovarian Stimulation (10–14 Days)
Ovarian stimulation involves daily injections of fertility medications (gonadotropins) to encourage multiple follicles to develop. You will visit the clinic every 2–3 days for monitoring (ultrasound and blood tests) to track follicle growth and adjust medication doses.
Timeline: Stimulation typically lasts 10 to 14 days, but can be shorter or longer depending on your response. Most patients stay in Thailand throughout this period.
Phase 4: Egg Retrieval (1 Day)
When the follicles are mature, you will receive a trigger injection to finalize egg maturation. The egg retrieval procedure is performed under sedation or anesthesia and takes about 20–30 minutes. You will need to rest for a few hours after the procedure and can usually return to your accommodation the same day.
Timeline: The retrieval is a single day procedure, but you should plan for at least one day of rest afterward. Most clinics recommend staying in Thailand for at least 24–48 hours post-retrieval.
Phase 5: Fertilization and Embryo Culture (3–6 Days)
After retrieval, the eggs are fertilized with sperm (either from a partner or donor) and the resulting embryos are cultured in the laboratory for 3 to 6 days. The embryologist will monitor development and grade the embryos.
Timeline: Embryo culture takes 3 to 6 days. During this time, you do not need to be at the clinic daily, but you should remain in Thailand in case of any updates or decisions.
Phase 6: Preimplantation Genetic Testing (PGT) – If Applicable (10–14 Days)
If you are planning to have PGT (for chromosomal abnormalities or genetic disorders), embryos are biopsied on Day 5 or Day 6 and then vitrified (frozen) while the biopsy samples are sent to a genetics laboratory. The testing process typically takes 10 to 14 days.
Timeline: If you opt for PGT, you will need to wait for the results before proceeding with a frozen embryo transfer. This means you may either stay in Thailand for the entire wait (adding 10–14 days to your stay) or return home and come back later for the transfer. Many international patients choose to return home and schedule the transfer in a subsequent cycle.
Phase 7: Embryo Transfer (1 Day)
For a fresh transfer (without PGT), the transfer usually occurs on Day 5 or Day 6 after egg retrieval. For a frozen transfer (with or without PGT), the transfer is performed in a subsequent cycle after preparing the uterine lining with medications. The transfer itself is a quick procedure (about 10–15 minutes) and does not require anesthesia.
Timeline: Fresh transfer adds 5–6 days after retrieval. Frozen transfer requires additional preparation (typically 2–4 weeks of medication) and can be done in a later cycle, either during the same trip (if you stay for PGT results) or on a separate trip.
Total Stay Duration: 2 to 6 Weeks
Here is a summary of possible timelines:
- Fresh transfer without PGT: Approximately 2–3 weeks in Thailand (arrival on Day 1, stimulation 10–14 days, retrieval, culture 5–6 days, transfer).
- Frozen transfer with PGT (same trip): Approximately 4–6 weeks (stimulation, retrieval, PGT wait 10–14 days, then frozen embryo transfer preparation 2–4 weeks).
- Frozen transfer with PGT (separate trip): First trip 2–3 weeks (stimulation, retrieval, biopsy), then return home. Second trip 2–4 weeks (for frozen transfer preparation and transfer).
- Donor egg cycle: If using donor eggs, the timeline depends on the donor’s availability and synchronization. Typically, the recipient’s preparation takes 2–4 weeks, and the transfer is scheduled accordingly. Total stay may be 2–4 weeks.
- Surrogacy: Surrogacy involves additional legal and medical steps, and the timeline is significantly longer (several months). The intended parents may need to be in Thailand for specific procedures, but the surrogate’s cycle is managed separately.
Factors That Can Affect Your Timeline
- Your ovarian response: Some patients may need longer stimulation or may have a cancelled cycle.
- Clinic protocols: Different clinics may have slightly different protocols for medication and monitoring.
- PGT results: If no embryos are suitable for transfer after PGT, the cycle may end without a transfer.
- Legal and administrative requirements: For donor eggs or surrogacy, additional paperwork and legal processes can add time.
- Travel and accommodation: Visa requirements, flight availability, and personal schedule can also affect your stay.
Important Considerations for International Patients
This timeline is a general guide. Every patient’s journey is unique, and your actual timeline will depend on your specific medical situation and the clinic’s recommendations. Always confirm the expected timeline with your chosen clinic before booking travel.

Frequently asked questions
How long do I need to stay in Thailand for IVF?
The total stay can range from 2 to 6 weeks, depending on whether you do a fresh or frozen transfer and whether you include PGT. A fresh transfer without PGT typically requires 2–3 weeks. A frozen transfer with PGT in the same trip may require 4–6 weeks. Many patients choose to do a frozen transfer in a separate trip, which splits the stay into two shorter visits.
Can I do the initial consultation online?
Yes, most fertility clinics in Thailand offer online consultations for international patients. You can discuss your medical history, receive instructions, and start the preparation process from your home country.
How long does PGT take in Thailand?
PGT (preimplantation genetic testing) typically takes 10 to 14 days from the time of embryo biopsy to receiving results. During this time, embryos are frozen and you may either wait in Thailand or return home and come back for a frozen transfer later.
Is a fresh transfer faster than a frozen transfer?
Yes, a fresh transfer is faster because it occurs 5–6 days after egg retrieval, without the need for a separate cycle. However, fresh transfers are not always recommended, especially if PGT is planned or if there is a risk of ovarian hyperstimulation syndrome (OHSS).
Does using donor eggs change the timeline?
Yes, using donor eggs can affect the timeline because the donor's cycle must be synchronized with the recipient's uterine preparation. Typically, the recipient will need to be in Thailand for 2–4 weeks for the transfer cycle, but the exact timing depends on the donor's availability and clinic protocols.
