No. Single women can't have IVF in Thailand, because the ART Act of 2015 limits assisted reproduction to a legally married couple, and clinics ask for your marriage certificate before treatment. What you can do as a single woman is freeze your eggs. You'd only be able to use them for IVF in Thailand once you're legally married.
That's the position as of 31 October 2026. A draft amendment is in progress, but it doesn't open IVF to single people. If you're married, or plan to be, you can compare providers in our directory of fertility clinics in Bangkok.
Why single women are excluded
Thailand regulates fertility treatment through the Protection of a Child Born by Medically Assisted Reproductive Technology Act B.E. 2558 (2015). The Act is written for a legally married husband and wife, and peer-reviewed and legal summaries agree that it limits treatment to legally married couples. Clinics such as SAFE Fertility ask for a marriage certificate, and a certificate issued abroad usually needs a Thai translation and legal certification.
The same applies to donor sperm. Donor insemination is still assisted reproduction under the Act, so it needs a married couple's consent. A single woman can't use a sperm donor in Thailand either.
What changed in 2025, and what didn't
Thailand's Marriage Equality Act came into force on 23 January 2025, and same-sex couples have been able to register their marriages since then. The ART Act wasn't changed at the same time. It still says "husband and wife", and legal commentators note that the Marriage Equality Act doesn't carry across provisions that treat a husband and a wife differently. In practice, clinics generally aren't treating married same-sex couples yet.
The Department of Health Service Support ran a public consultation on a revised ART bill from 2 to 31 July 2026. The draft would replace "husband and wife" with "spouses" to match the Marriage Equality Act. That would open treatment to married same-sex couples. It wouldn't help single women, because spouses still means a legal marriage. Legal commentary from September 2026 says the bill still has to go to the Cabinet and through parliament, and we found no sign it had become law by 31 October 2026.
What a single woman can do in Thailand
| Option | Allowed for a single woman? | Notes |
|---|---|---|
| IVF or ICSI | No | Legally married couples only |
| IUI with donor sperm | No | Needs written consent from a married husband and wife |
| Egg freezing | Yes, at Bangkok clinics | Clinics such as GFC list it as suited to single women |
| Using your frozen eggs later | Only once married | Fertilising them is IVF/ICSI, so the marriage rule applies |
| Taking frozen eggs abroad | No, under current rules | The 2026 draft would allow exports with committee approval; confirm with your clinic |
| Surrogacy | No | Limited to married couples with at least one Thai spouse |
The formal rules on egg storage were written with married couples and medical reasons, such as chemotherapy, in mind. In practice, Bangkok clinics offer egg freezing to single women. GFC's egg-freezing page lists it as suited to single women and to women delaying pregnancy. Ask the clinic to confirm in writing what paperwork it needs before you start. Our guide to egg freezing costs in Thailand covers prices.
Things to weigh before you travel
- Plan where you'll use the eggs. Frozen eggs can't legally leave Thailand under the current law, so you'd need to come back to a Thai clinic, married, to use them.
- Check the rules at home. If you want IVF as a single woman now, another country may allow it. Ask a fertility clinic or lawyer there.
- Don't accept a workaround. A clinic offering IVF to a single woman in Thailand is offering something the law doesn't allow.
- Watch the draft law. If you're in a same-sex marriage, the July 2026 bill could change your options once it's enacted. Ask clinics whether anything has changed before you book.
FAQ
Can a single woman use donor sperm in Thailand?
No. Treatment with donor sperm is assisted reproduction under the ART Act, which is limited to legally married couples. Single women can't use donor sperm for IUI or IVF in Thailand.
Can I freeze my eggs in Thailand if I'm single?
Yes. Bangkok clinics offer egg freezing to single women. You'll only be able to use the eggs for IVF in Thailand once you're legally married, and you can't take them out of the country under the current law.
Did the Marriage Equality Act open IVF to same-sex couples?
Not yet. The Act lets same-sex couples marry from 23 January 2025, but the ART Act still says "husband and wife". A draft that would change this to "spouses" went to public consultation in July 2026 and hadn't become law at the time of writing.
Can unmarried couples do IVF in Thailand?
No. You need to be legally married, and the clinic will ask for your marriage certificate. A certificate issued abroad usually needs a translation and legalisation.
Will the law change for single women?
We've seen nothing to suggest it will soon. The 2026 draft keeps the marriage requirement and only widens it to married couples of any gender.
