IVF and Fertility Clinics in Thailand

Eligibility and the law in Thailand

Assisted reproduction in Thailand is governed by the Protection of Children Born from Assisted Reproductive Technologies Act B.E. 2558 (2015). As enacted, the Act limits treatment to legally married couples, bans commercial surrogacy and trade in eggs and sperm, and requires each surrogacy arrangement to be approved by a committee.

The law is under review. In July 2026 the Department of Health Service Support opened public consultation on a revised bill which, as reported, would extend access to married same-sex couples following the 2024 marriage equality law, allow some foreign married couples to use surrogacy, and permit export of eggs, sperm and embryos with committee approval. A draft is not the law: ask each clinic which rules apply on the date you start, and what documents (such as a marriage certificate and its translation) it needs from you.

Hospital fertility unit or standalone clinic

IVF is offered both by fertility units inside general hospitals and by standalone fertility clinics. A hospital unit can call on other departments on site, such as emergency care, anaesthesia and obstetrics, which may matter if you have other health conditions or if a complication such as ovarian hyperstimulation needs inpatient care. A standalone clinic may offer more continuity with one team.

Neither model is better in itself. Ask who will see you at each visit, who performs egg collection and transfer, where you would be admitted if something went wrong, and who answers the phone out of hours.

The laboratory and the embryologists

Much of what happens in an IVF cycle happens in the laboratory, out of sight. Ask who leads the embryology team, how many cycles the lab handles each year, and how eggs and embryos are labelled and checked to prevent mix-ups.

Some clinics hold external laboratory accreditation, such as RTAC certification (the Australian and New Zealand scheme) or ISO 15189 for medical laboratories. If a clinic mentions one, ask to see the current certificate and check that it covers the IVF laboratory itself.

Ask whether embryos and eggs are frozen by vitrification (rapid freezing) or slow cooling, and what the lab's survival rate after thawing is. If time-lapse incubation is offered, note that the UK regulator, the HFEA, rates it as having no effect on the chance of a baby based on current evidence.

How to read success rates

A success rate depends on what is counted and who is counted. Check three things before comparing any two figures: the outcome (a positive pregnancy test, a clinical pregnancy seen on a scan, or a live birth), the denominator (per cycle started, per egg collection, or per embryo transferred), and the age group.

Regulators urge caution. The US CDC says comparisons between clinics should be made with caution and may not be meaningful, because clinics treat different patients and use different methods. The HFEA advises using success rates as a rough guide rather than a prediction, and looking at the multiple birth rate alongside the birth rate. A clinic's figures do not tell you your own chance; ask the specialist about that directly.

Itemised costs and package small print

Packages bundle different steps, so the cheapest headline price is not necessarily the cheapest cycle. Ask for an itemised, written quote based on your own test results and compare the same lines across clinics.

Check the conditions too: who the package applies to (some are limited by nationality or residence), how long it is valid, what is refunded if the cycle is cancelled or no embryo is suitable for transfer, and whether it can be combined with insurance.

Add-ons deserve particular care. PGT-A (genetic screening of embryos) is often sold as a way to improve results, but the HFEA rates it red for improving the chance of a baby for most patients, while rating it green for reducing miscarriage. The HFEA says a clinic should be able to show you the evidence for any treatment it offers.

• Pre-treatment tests and consultations
• Stimulation medication, and the cost of any dose above the package allowance
• Monitoring scans and blood tests
• Egg collection, anaesthesia and ICSI
• Embryo culture, time-lapse and genetic testing (PGT-A)
• Freezing, annual storage and each frozen embryo transfer (FET)

Embryo transfer policy

Twin and triplet pregnancies carry higher risks for both the pregnant person and the babies, and ESHRE's guideline favours transferring a single embryo. The HFEA notes that single embryo transfer is usual practice for most patients in the UK, but not every country follows it.

Ask how many embryos the clinic usually transfers for someone of your age, whether it will put its recommendation in writing, and what its multiple birth rate is.

Travelling for treatment, storage and moving embryos

A full cycle runs over several weeks, and a freeze-all plan splits it into two trips. Ask which tests and early monitoring scans can be done at home and sent to the clinic, how many days you must be present,. Ask for copies of your records, and how complaints are handled: the HFEA notes a home-country regulator cannot help with treatment abroad.

If embryos are frozen, read the storage terms before you start: the annual fee, how you will be reminded, and what happens if you cannot be contacted or stop paying. Moving embryos or eggs out of Thailand is regulated, and the 2026 draft bill proposes committee approval for export. Ask the clinic what is required today, who arranges transport, and whether a clinic in your home country can legally receive them.
