IVF and Fertility Clinics in Thailand

First, check you can be treated

Before comparing clinics, confirm you qualify. In its current form, Thailand's Protection of Children Born from Assisted Reproductive Technologies Act B.E. 2558 (2015) allows treatment only for legally married couples. It also prohibits commercial surrogacy and any buying or selling of eggs and sperm, and every surrogacy arrangement needs a committee's approval.

Change may be coming. The Department of Health Service Support began consulting the public on a revised bill in July 2026. According to reports, the draft would open treatment to same-sex spouses, in line with the marriage equality law passed in 2024, let some foreign married couples use surrogacy, and allow eggs, sperm and embryos to be exported once a committee approves. Until it is passed, the existing Act applies, so ask each clinic in writing which rules it will follow on your start date and which documents it wants, such as your marriage certificate and a translation.

Planning the trip around your cycle

An IVF cycle takes several weeks from the first injection to embryo transfer, and if all embryos are frozen first, the transfer becomes a second visit. Ask early which baseline tests and monitoring scans a clinic will accept from a doctor at home, and exactly how many days you need to be in Thailand for each stage.

Keep copies of every result and report as you go. The UK regulator, the HFEA, points out that your home regulator has no power over a clinic abroad, so find out before you pay how the clinic deals with complaints.

What happens behind the lab door

You will spend little time in the embryology lab, but your eggs and embryos spend days there. Ask who heads the embryology team, roughly how many cycles the lab runs a year, and what double-checks it uses so that samples cannot be confused.

Some labs carry outside accreditation, for example RTAC certification (a scheme run in Australia and New Zealand) or the ISO 15189 standard that applies to medical labs. Where a clinic quotes one, request the current certificate and confirm it names the IVF lab rather than another part of the hospital.

Find out whether the lab freezes by vitrification, a rapid method, or by slow cooling, and what share of embryos survive thawing there. If you are offered time-lapse incubation, the HFEA's current rating is that it makes no difference to the chance of having a baby.

Hospital unit or dedicated fertility clinic

In Thailand you can be treated in a fertility unit within a general hospital or at a clinic that does nothing but fertility care. A hospital unit has emergency, anaesthesia and maternity teams in the same building, which can help if you have another medical condition or develop ovarian hyperstimulation and need admission. A dedicated clinic can mean seeing the same small team throughout.

One is not automatically better than the other. What counts is knowing who you will see at each appointment, who carries out egg collection and transfer, where you would go if you became unwell, and how to reach someone at night.

Making sense of the numbers

Before you set one clinic's rate against another's, find out three things: whether it measures positive tests, scan-confirmed pregnancies or live births; whether the base is each cycle begun, each collection or each transfer; and which age band it describes.

Regulators advise care here. The US CDC warns that clinic-to-clinic comparisons may not be meaningful because patients and methods differ. The HFEA suggests treating published rates as a rough guide, not a forecast, and reading the multiple birth rate next to them. Ask your specialist about your own likely chances instead of relying on a clinic average.

One embryo or two

Carrying twins or triplets raises the risks for the pregnancy and for the babies, which is why ESHRE's guideline leans towards transferring one embryo at a time. The HFEA says single embryo transfer is standard for most UK patients, though practice in other countries varies.

Ask what the clinic normally advises for patients of your age, whether that advice can be given to you in writing, and what proportion of its births are multiples.

Reading a quote line by line

Because packages leave out different steps, a low headline figure can end up costing more. Request a written breakdown based on your own test results, then line the clinics up item by item.

Read the conditions as well: whether the package is restricted by nationality or residence, when it expires, what you get back if the cycle stops early or no embryo can be transferred, and whether insurance can be used alongside it.

Be cautious with extras. PGT-A, which screens embryos for chromosome problems, is often promoted as raising success rates, yet for most patients the HFEA rates it red on raising the odds of a baby, and green for lowering the risk of miscarriage. The HFEA expects clinics to show you the evidence behind anything they offer.

• Consultations and tests before treatment
• Stimulation drugs, including any extra doses beyond the package
• Scans and blood tests during monitoring
• Egg collection, the anaesthetic and ICSI
• Embryo culture, time-lapse and PGT-A
• Freezing, yearly storage and each frozen embryo transfer

Frozen embryos after you go home

If embryos are stored, read the storage contract before treatment begins: what it costs each year, how the clinic will remind you, and what it will do if it cannot reach you or payments stop.

Taking embryos or eggs out of Thailand is controlled, and the 2026 draft would require committee approval for export. Ask what the current requirements are, who organises the shipping, and whether a clinic in your own country is legally able to accept them.
