Fertility Treatment in Thailand
Every year, couples and single patients from around the world come to Thailand for IVF, and most of them come for the same reasons: internationally accredited laboratories, experienced fertility teams, appointments within days rather than months, and a cycle that costs a fraction of what it would at home.
I run Thailand Care, which helps international patients arrange treatment at hospitals in Bangkok, so this is the part of fertility treatment I know best. I have seen first-hand how much good planning matters. The patients who do best arrive knowing what Thai law allows, how long they need to stay, and how their clinic in Bangkok and their doctor at home will work together.
Travelling for something this personal can feel daunting, especially if you are coming on your own. With the right preparation it becomes a calm, well-run few weeks, away from work and the pressure of everyday life. For the clinics themselves, see my ranked list of the best IVF clinics in Thailand.

Why Thailand
Bangkok has some of the most advanced fertility clinics in Asia. The leading ones hold international accreditation for their hospitals and their laboratories, from JCI and from RTAC, Australia and New Zealand's fertility accreditation body. They culture embryos in time-lapse incubators, freeze by vitrification, and run genetic testing of embryos in-house. The most established have been doing IVF since the 1990s.
The second reason is access. A first consultation is usually available within days, and a cycle can often start with your next period. For people facing a long wait at home, or watching their age move them into a lower success band, that time matters.
The third is cost. A cycle at an accredited Bangkok clinic is typically quoted at about $6,000 to $12,000, with drugs often included, against $12,000 to $20,000 plus drugs in the US. See what fertility treatment costs for the full comparison.
What Thai law allows
Assisted reproduction in Thailand is governed by a specific law, and it shapes what foreigners can do there. Parts of it have been under review, so confirm the current position with your clinic as you plan.
- Marriage. Thai law has long limited IVF to legally married couples, and clinics ask for a marriage certificate. The position for same-sex married couples and single women has been changing since Thailand's 2025 marriage equality law, so ask the clinic what it can offer you today.
- Egg freezing. Freezing your own eggs for later use is widely available, including for single women.
- Sex selection. Choosing an embryo's sex for non-medical reasons is prohibited. PGT-A can be done, but the sex of the embryo will not be reported.
- Surrogacy. Commercial surrogacy is prohibited, and surrogacy is tightly restricted for foreigners.
- Donors. Donor eggs, sperm and embryos can be used, but donation must not be commercial.
- Moving embryos and gametes. Taking frozen embryos, eggs or sperm out of Thailand needs official approval and a specialist courier. Ask how the clinic handles it before you freeze anything there.
None of this is legal advice. Every leading clinic in Bangkok deals with these rules daily and will tell you plainly what applies to you.
Before your first video consultation
Have a scan of your marriage certificate and both passports ready to send. Clinics ask for them early, and having them to hand keeps the first steps moving.
How long to stay
Your clinic sets this, and it depends on the treatment and how much of the cycle you can start at home. As a guide:
- A full IVF cycle with a fresh transfer: about two and a half to three weeks, from early in stimulation through egg collection to a day 5 transfer.
- IVF with all embryos frozen: about two weeks, ending a day or two after egg collection, with the transfer on a later trip.
- A frozen embryo transfer: about a week, with the lining prepared at home and the final scans and transfer in Bangkok.
- Egg freezing: about two weeks.
- IUI: a few days around ovulation, timed by scans.
Many clinics let you start the injections at home, with scans at a local clinic, and fly in for the second half of stimulation. That can shorten the stay by several days. Ask whether your clinic works this way and which scans it needs to see.
The partner providing sperm needs to be there for the day of egg collection, or to have frozen a sample at the clinic beforehand.
The journey
Medication. If you start the injections at home, carry them in your hand luggage with the prescription and a letter from your clinic. Some need to stay cool, so pack them in an insulated pouch with a cool pack and ask the airline about it before you fly.
Flying after egg collection. Most people fly a day or two after collection without any problem. If you have a lot of follicles, your clinic may ask you to stay longer, because OHSS is most likely in the days after collection.
Flying after transfer. There is no good evidence that flying after an embryo transfer lowers the chance of pregnancy, and many people fly home within a few days. Ask your clinic when they are happy for you to go, and drink plenty of water and walk the aisle on the flight.
Visas. Many nationalities can enter Thailand without a visa for a stay long enough for one cycle. Thailand also offers medical treatment visas for longer or repeated stays. Check the rules for your passport before you book flights.
The week before you fly
Put every medication, the prescription and your clinic's letter into one clearly labelled pouch in your hand luggage. At security and on arrival, having it all in one place turns a nervous moment into a quick one.
Keeping care joined up
Treatment abroad works best when your clinic in Bangkok and your doctor at home are working from the same information. Before you travel, ask your GP or local gynaecologist whether they are happy to do monitoring scans, blood tests and pregnancy care afterwards.
Bring home a full set of records: the stimulation drugs and doses, the egg collection report, the fertilisation and embryo culture report with the grades, the transfer note, the number and grade of any frozen embryos, and the plan for progesterone support. If you become pregnant, your doctor at home will want the transfer date, and if you need another cycle, any clinic will want the rest.
Ask your clinic how follow-up works once you are home. The best ones give you a named coordinator, answer messages quickly, and arrange video consultations to review results and plan the next step.
Choosing your clinic from abroad
Judge a Thai clinic exactly as you would one at home, using choosing a fertility clinic: the laboratory and its accreditation, live birth rates per cycle started for your age, the experience of the team, and an all-in price in writing.
Add three questions for treatment from abroad. Will I see the same doctor at each visit? Do you have staff who speak my language, and a coordinator I can message directly? And how do you handle frozen embryos if I want to transfer them later, here or at home?
My ranked list of the best IVF clinics in Thailand and the profiles in the clinic directory give you a strong place to start.
