We found no published legal maximum age for IVF in Thailand. The ART Act of 2015 sets who can have treatment (a legally married couple), not how old you can be, so each clinic decides case by case based on your age, your egg reserve and your health.
In practice, your age changes the price, the package you qualify for and your chance of success far more than it changes whether a clinic will treat you. To see which providers might suit your case, start with our directory of fertility clinics in Bangkok.
Why there's no single age limit
Thailand regulates IVF through the Protection of a Child Born by Medically Assisted Reproductive Technology Act B.E. 2558 (2015). The Act and the Medical Council rules made under it focus on who can be treated, consent, embryo testing and surrogacy. We couldn't find a maximum age for women having IVF with their own eggs in any of the public summaries we checked. We couldn't open the official Medical Council notices from outside Thailand, so ask your clinic to confirm.
The one age rule we did find applies to surrogates, not to patients. Legal summaries of the Act's criteria say a surrogate who isn't a relative must be aged 20 to 40.
So the real limit is medical. A doctor will look at your AMH level, scan results and general health, then tell you whether IVF with your own eggs makes sense.
How age shows up in Bangkok clinic packages
Clinics don't usually publish an upper limit, but some build age into their prices.
| Provider | How age affects the package |
|---|---|
| Genesis Fertility Center (GFC) | LiTE package (฿150,000) for women 35 or under; Gold for 37 or under. Both need an AMH of at least 1.2. Women over 37 go to the ฿230,000 or ฿350,000 package |
| Bangkok Hospital | ฿456,000 package with PGT-A and freezing for 2 embryos is aimed at women over 35 or after miscarriage |
| MedPark Hospital | Advises freezing 8–10 eggs per hoped-for pregnancy if you're under 35 |
| Nakornthon Hospital | Recommends egg freezing before 35, and using frozen eggs before 40–45 |
Prices and age bands are the providers' own published figures in October 2026. Confirm them in writing before you book.
What changes as you get older
Fewer eggs per cycle. Bangkok Hospital notes that egg numbers fall from around 37. You may need more stimulation medication, which costs more if your package caps the dose.
More embryo testing. Under the Medical Council's rules on embryo testing, a woman aged 35 or older can have embryos tested when there's a medical reason to think they're at risk of a genetic abnormality. Many doctors suggest PGT-A at this stage. At GFC that's ฿39,900 for the first embryo and ฿15,900 for each one after.
More than one cycle. Older patients more often need a second retrieval. Ask what a second attempt costs before you start the first.
Donor eggs are limited. Egg donation is legal in Thailand, but commercial donation isn't, and clinics can't sell donor eggs. If you're relying on donor eggs, ask how the clinic finds donors and how long you might wait.
We don't quote success rates by age here. No Bangkok provider publishes audited, age-adjusted live-birth rates we could compare fairly. Ask each clinic for its own figures for your age group, and how they measure them.
What to check
- Ask for the clinic's own age policy. Some will treat you with your own eggs into your mid-40s; some won't. Get the answer before you fly.
- Send your AMH result first. It decides which package you qualify for at clinics like GFC, and whether IVF with your own eggs is worth trying.
- Bring your marriage certificate. Age doesn't matter if you aren't eligible. IVF in Thailand is limited to legally married couples, and a foreign certificate usually needs translation and legalisation.
- Ask about PGT pricing. If you're over 35, it's likely to come up.
- Plan for medication costs. Higher doses are common as you get older, and caps vary.

FAQ
Is there a legal age limit for IVF in Thailand?
We found none. The ART Act of 2015 limits IVF to legally married couples but doesn't set a maximum age for the woman. Each clinic sets its own policy, based on your egg reserve and health.
Can I do IVF in Thailand at 45?
Possibly. Some Bangkok clinics treat women in their 40s, but your chances with your own eggs drop sharply. Send your AMH result and history to two or three clinics and ask each one directly.
Is IVF more expensive in Thailand if I'm over 35?
Often, yes. At GFC, the cheapest package is for women 35 or under, and women over 37 start at ฿230,000. You're also more likely to need PGT-A and extra medication.
Is there an age limit for egg freezing in Thailand?
We found no legal limit. Clinics such as GFC say the ideal window is 20–35, but freezing is still possible after 35, and in some cases after 40.
Is there an age limit for surrogates in Thailand?
Yes. Legal summaries of the ART Act's criteria say a surrogate who isn't a relative must be 20 to 40. Surrogacy itself is limited to married couples where at least one spouse is Thai.
