At a glance
A frozen embryo transfer (FET) cycle in Thailand typically spans several weeks, including preparation, monitoring, and the transfer procedure. The exact timeline depends on your individual protocol and clinic requirements.
Understanding the Frozen Embryo Transfer (FET) Cycle
A frozen embryo transfer (FET) cycle involves preparing your uterine lining to receive a previously frozen embryo. Unlike a fresh IVF cycle, FET does not require ovarian stimulation or egg retrieval, making the timeline shorter and more predictable. However, the total duration still depends on your individual treatment plan and the clinic’s protocols.
Typical FET Cycle Timeline
While exact days vary, a standard FET cycle in Thailand generally follows this sequence:
- Initial consultation and baseline tests: 1–2 days (can be done remotely or in person)
- Endometrial preparation: 10–14 days of medication (estrogen) to thicken the uterine lining
- Monitoring visits: 2–4 ultrasound and blood tests during preparation
- Progesterone start: Typically 5–6 days before transfer
- Embryo transfer procedure: 1 day (outpatient procedure)
- Post-transfer rest and pregnancy test: 9–14 days after transfer
The entire cycle from start of medication to pregnancy test usually takes about 4–6 weeks. However, some clinics may recommend a longer preparation phase or additional tests.
Minimum Stay in Thailand for FET
For international patients, the minimum stay in Thailand depends on how much of the cycle you complete before traveling. Many patients choose to do the initial consultation and some monitoring remotely, then travel to Thailand closer to the transfer date. A common approach is:
- Option 1: Travel for transfer only: Stay 5–7 days (transfer day plus a few days of rest)
- Option 2: Travel for monitoring and transfer: Stay 2–3 weeks (includes baseline and monitoring visits)
- Option 3: Complete cycle in Thailand: Stay 4–6 weeks (full preparation and monitoring)
Your clinic will advise on the recommended schedule based on your medical history and protocol.
Factors That Affect the Timeline
- Type of endometrial preparation: Natural cycle, modified natural cycle, or hormone replacement therapy (HRT) each have different lengths.
- Embryo stage: Blastocyst transfers may have slightly different timing than cleavage-stage transfers.
- Clinic protocols: Some clinics require additional tests or a mock cycle before FET.
- Individual response: Your lining thickness and hormone levels may require adjustments to medication duration.
Questions to Ask Your Clinic
To plan your travel accurately, ask your chosen clinic:
- What is the typical timeline for an FET cycle in your clinic?
- Can I do initial monitoring at home and send results?
- What is the minimum number of in-person visits required?
- How long should I plan to stay in Thailand?
- What is the protocol for medication start and transfer date?
Next Steps for Planning
- Consult with a fertility specialist to determine if FET is right for you.
- Choose a clinic and discuss your travel schedule.
- Arrange time off work and accommodation based on the recommended stay.
- Prepare necessary medical records and any required documents.

Frequently asked questions
Can I do a frozen embryo transfer cycle in less than a month?
A full FET cycle from start of medication to pregnancy test typically takes at least 4 weeks. However, if you complete preparation remotely and travel only for the transfer, your stay in Thailand could be as short as 5–7 days.
How many monitoring visits are needed during an FET cycle?
Most clinics require 2–4 monitoring visits (ultrasound and blood tests) during the endometrial preparation phase. The exact number depends on your protocol and how your body responds.
Do I need to stay in Thailand after the embryo transfer?
Many clinics recommend staying in Thailand for a few days after transfer for rest and to have the pregnancy test done locally. Some patients choose to return home earlier and arrange for a pregnancy test at home, but confirm with your clinic.
Can I start FET medication at home before traveling to Thailand?
Yes, some clinics allow you to begin estrogen medication at home under their guidance, with monitoring done locally. This can reduce your stay in Thailand. Discuss this option with your clinic.
What is the difference between a natural cycle FET and a hormone replacement FET in terms of timeline?
A natural cycle FET follows your own ovulation and may require more frequent monitoring, but the timeline is similar (around 4 weeks). A hormone replacement FET uses medications to control the cycle, which can be more predictable but may take slightly longer if additional tests are needed.
