IVF Cycle Length for International Patients in Thailand: What to Expect

Understanding the IVF Timeline for International Patients

When planning an IVF cycle in Thailand, one of the first questions international patients ask is: How long do I need to stay? The answer depends on the type of cycle (fresh or frozen embryo transfer), your individual treatment plan, and how your body responds to medications. This guide provides a general overview to help you plan your travel, but always confirm specific timelines with your chosen clinic.

At a Glance: Typical Stay Durations

• Fresh IVF cycle (with own eggs): Approximately 2–3 weeks in Thailand.
• Frozen embryo transfer (FET): Typically 1–2 weeks, depending on the protocol.
• Egg donation cycle (as recipient): Usually 1–2 weeks for the transfer.
• Pre-treatment preparation: Some patients may need to start medications before traveling; this can shorten the in-country stay.

These are general estimates. Your clinic will provide a personalized calendar based on your medical history and treatment plan.

Fresh IVF Cycle: Step-by-Step Timeline

A fresh IVF cycle involves ovarian stimulation, egg retrieval, fertilization, embryo culture, and embryo transfer—all within one menstrual cycle. Here’s what a typical timeline might look like:

Week 1: Arrival and Baseline Monitoring

• Day 1–3 of your menstrual cycle: Arrive in Thailand. You’ll have a baseline ultrasound and blood tests to confirm your ovaries are ready for stimulation.
• Days 3–12: Daily or every-other-day monitoring appointments (ultrasound and blood work) to track follicle growth. You’ll also start injectable fertility medications (gonadotropins).

Week 2: Trigger, Retrieval, and Fertilization

• Day 10–14: When follicles are mature, you’ll take a trigger shot (hCG or GnRH agonist) to finalize egg maturation.
• 36 hours after trigger: Egg retrieval procedure (usually outpatient, under sedation). Plan for a rest day afterward.
• Days after retrieval: Embryos are cultured in the lab for 3–6 days. You may have a few days of rest or light activity.

Week 3: Embryo Transfer and Rest

• Day 3–6 after retrieval: Embryo transfer (fresh or frozen, depending on your plan). The procedure is quick and usually painless.
• After transfer: Most clinics recommend 1–2 days of rest before traveling home. Some patients stay longer for a pregnancy test (about 10–14 days after transfer), but many opt to have this done at home.

Total stay for fresh cycle: Approximately 2–3 weeks. If you choose to stay for the pregnancy test, add another week.

Frozen Embryo Transfer (FET) Timeline

FET cycles are shorter because they don’t require ovarian stimulation or egg retrieval. The timeline depends on whether you use a natural cycle (ovulating on your own) or a medicated cycle (hormone replacement).

Natural Cycle FET

• Arrival: Around day 8–10 of your cycle for monitoring.
• Monitoring: Every 1–2 days until ovulation is detected.
• Transfer: About 5–7 days after ovulation.
• Total stay: Approximately 10–14 days.

Medicated Cycle FET

• Arrival: You may start estrogen medication before traveling. Once in Thailand, monitoring begins around day 10–14 of medication.
• Transfer: After the uterine lining is thick enough (usually 10–14 days of estrogen), progesterone is added, and transfer occurs 5–7 days later.
• Total stay: Approximately 2–3 weeks, but some patients can shorten this by starting medications at home.

Factors That Can Affect Your Stay

• Response to medications: Some patients need more or fewer days of stimulation.
• Embryo development: If embryos are cultured to blastocyst (day 5–6), the transfer may be later.
• Genetic testing (PGT): If you opt for preimplantation genetic testing, embryos are biopsied and frozen, and transfer is delayed to a subsequent cycle. This means a shorter initial stay (for retrieval only) and a separate trip for FET.
• Clinic protocols: Each clinic has its own schedule. Always ask for a detailed calendar before booking flights.

Questions to Ask Your Clinic

• What is the estimated timeline for my specific treatment plan?
• How many monitoring appointments will I need, and at what times?
• Can I start any medications before traveling to Thailand?
• What is the recommended rest period after egg retrieval and embryo transfer?
• Do you offer remote monitoring or coordination with a local doctor at home?

Planning Your Travel

• Flights: Book flexible tickets if possible, in case your timeline shifts.
• Accommodation: Choose a place near the clinic for convenience during daily monitoring.
• Time off work: Plan for at least 2–3 weeks for a fresh cycle, or 1–2 weeks for FET.
• Support person: Consider bringing a partner or friend for emotional support and assistance after procedures.

Next Steps

Once you have a preliminary timeline from your clinic, you can start planning your travel. Remember that every patient is different, and your actual schedule may vary. Stay flexible and communicate openly with your medical team.

Frequently asked questions

How long do I need to stay in Thailand for a fresh IVF cycle?

A fresh IVF cycle typically requires a stay of 2 to 3 weeks. This includes baseline monitoring, ovarian stimulation (about 10–12 days), egg retrieval, embryo culture (3–6 days), and embryo transfer. Some patients choose to stay longer for a pregnancy test, but many have this done at home.

Can I shorten my stay by starting medications before I travel?

In some cases, yes. For frozen embryo transfer (FET) cycles, you may be able to start estrogen medication at home and travel later for monitoring and transfer. For fresh cycles, stimulation usually begins after arrival. Ask your clinic if a split protocol is possible.

How many monitoring appointments will I need?

During ovarian stimulation, you will likely need daily or every-other-day appointments for ultrasound and blood tests. For FET, monitoring is less frequent. Your clinic will provide a schedule. Plan to be near the clinic during this period.

What if my cycle is cancelled or delayed?

Cycle cancellations or delays can happen due to poor response, health issues, or other factors. Discuss contingency plans with your clinic, including whether you can return home and resume later. Flexible travel bookings are advisable.

Do I need to stay for the pregnancy test?

Not necessarily. Many international patients choose to have the pregnancy test (blood hCG) done at a local lab at home and share results with their clinic. However, some clinics prefer you to stay. Confirm with your clinic.
