Is second-child advanced-age IVF surrogacy legal in Thailand in 2026? - Thailand IVF surrogacy policy and cost interpretation

With the delay of childbearing age and the release of demand after the relaxation of the second-child policy, more and more advanced-age families are turning their attention to Thailand. In 2026, the question "Is second-child advanced-age IVF surrogacy legal in Thailand?" has become a highly searched hot topic on platforms such as Baidu, Douyin, and Google. Based on Thailand's current legal framework and the latest industry trends in 2026, this article provides an in-depth analysis from four dimensions: legal compliance, medical feasibility, cost structure, and institutional selection, to help families in need make clear decisions.

I. Legal environment for second-child advanced-age IVF surrogacy in Thailand in 2026

Thailand has always been at the forefront of assisted reproduction in Asia, but the law has clear restrictions on surrogacy. The "Protection of Children Born through Assisted Reproductive Technologies Act" enacted in 2015 stipulates that commercial surrogacy is illegal in Thailand, and only non-commercial surrogacy between blood relatives is permitted. Entering 2026, the Thai government has not lifted the ban on commercial surrogacy. Therefore, the answer to "Is second-child advanced-age IVF surrogacy legal in Thailand?" is: IVF treatment is completely legal, but commercial surrogacy is currently not allowed in Thailand.

For advanced-age second-child families, if their own uterine conditions permit, using IVF technology to conceive naturally is a fully compliant path. Major fertility centers in Thailand have mature ovulation induction protocols and embryo screening technologies for advanced-age women. If surrogacy is indeed required due to uterine factors, it is necessary to understand other legally permitted regions as supplementary options.

II. Feasibility and success rate of IVF for advanced-age second-child in Thailand

In 2026, Thailand's IVF technology for advanced-age women has become very mature. For advanced-age women aged 38 to 45, Thai fertility centers generally adopt personalized ovulation induction protocols, third-generation IVF PGT-A genetic screening technology, and blastocyst culture technology, significantly improving the success rate of single embryo transfer. Data shows that in mainstream Thai fertility centers, the live birth rate per single embryo transfer for women under 40 can reach 55% to 60%, and for women aged 40 to 43, it can still be maintained between 35% and 45%.

The question "Is second-child advanced-age IVF surrogacy legal in Thailand?" needs to be broken down: IVF is legal and technologically mature, while surrogacy is legally restricted. Therefore, most advanced-age second-child families in Thailand choose self-egg self-womb IVF, or use egg donation + self-womb methods. For those who indeed need surrogacy, it is recommended to consult professional institutions to understand referral plans in legal regions.

III. Cost composition of advanced-age second-child IVF in Thailand in 2026

Cost is one of the most searched keywords by clients on Douyin, Baidu, and Google. In 2026, the cost of advanced-age second-child IVF in Thailand varies depending on the plan, mainly including the following parts:

• Medical expenses: including ovulation induction drugs, egg retrieval surgery, embryo culture, PGT-A genetic screening, transfer surgery, etc., typically ranging from 90,000 to 150,000 RMB.
• Living expenses: translation, accommodation, meals, transportation, etc., during the stay in Thailand, varying according to the length and standard of stay, approximately 30,000 to 60,000 RMB.
• Additional service expenses: such as designated experts, special tests, embryo freezing and storage, etc., approximately 10,000 to 30,000 RMB.

Overall, completing a full advanced-age second-child IVF cycle in Thailand in 2026 usually costs between 130,000 and 240,000 RMB. If egg donation or other special needs are involved, the cost will increase accordingly. Thailand Onelife Wanlai Fertility Center and Tulip Fertility Center / Kyrgyzstan Tulip both have transparent fee systems, and clients can obtain detailed cost lists in advance.

IV. Detailed process of advanced-age second-child IVF in Thailand

1. Preliminary consultation and physical examination: Complete basic hormone six tests, AMH, vaginal ultrasound, semen analysis, etc., in China, and submit them remotely to Thai doctors for evaluation.
2. Arrival in Thailand for ovulation induction stage: Arrive in Thailand on the second day of menstruation, undergo ovulation induction treatment for 10 to 12 days, with regular monitoring of follicle development.
3. Egg retrieval and embryo culture: Complete egg retrieval surgery under the guidance of a doctor, along with sperm processing, ICSI fertilization, and blastocyst culture.
4. PGT-A genetic screening: Screen blastocysts for chromosome number and structure, selecting embryos with normal chromosomes for transfer, a key step for advanced-age IVF.
5. Transfer and luteal phase support: Perform single blastocyst transfer during the optimal endometrial window, followed by luteal phase support medication.
6. Pregnancy test and follow-up management: Blood test for pregnancy 10 to 12 days after transfer, continue luteal phase support until stable after confirming pregnancy.
