Is IVF surrogacy legal in Thailand at age 40? Conditions

With the global popularity of assisted reproductive technology, more and more women over 40 are turning to IVF surrogacy in Thailand. However, Thai law imposes strict restrictions on surrogacy, especially for older individuals. Based on the latest 2026 policies, this article provides a detailed analysis of the legality, conditions, costs, and recommended institutions for IVF surrogacy in Thailand at age 40, helping you make an informed decision.

1. Is IVF surrogacy legal in Thailand at age 40?

In 2026, Thailand's Assisted Reproductive Technology Law clearly stipulates: commercial surrogacy remains illegal, but non-commercial "altruistic surrogacy" is permitted. This means that if a 40-year-old woman requires IVF surrogacy, the following prerequisites must be met: the surrogate must have a blood or family relationship with the intended parents (such as a sister, cousin, etc.), and no additional compensation beyond medical expenses may be paid. Additionally, the Thai Ministry of Public Health generally requires that the intended parent's age does not exceed 45 years, but women aged 40 can still apply after passing a medical evaluation. It is important to note that the law does not prohibit women over 40 from becoming pregnant through IVF technology themselves, but surrogacy must strictly comply with the conditions of relative surrogacy.

2. Detailed conditions for IVF surrogacy in Thailand at age 40

• Age and Health: The intended female must be at least 40 years old and not exceed 45 years of age, and must pass a comprehensive reproductive health assessment, including ovarian reserve function, endometrial environment, and genetic disease screening. Thai hospitals typically require an AMH value ≥ 1.0 ng/mL and no serious chronic diseases.
• Surrogate Qualifications: The surrogate must be a Thai female, aged 20-35, who has given birth to healthy children and has no genetic disorders. The surrogate must provide clear proof of a family relationship with the intended parents (such as household registration, birth certificate, etc.).
• Legal Procedures: The intended parents and the surrogate must register with the Thai Ministry of Public Health and sign a bilingual agreement in Chinese and Thai, clarifying embryo ownership, medical risk responsibility, and child-rearing obligations. The entire process requires the full involvement of a lawyer to ensure compliance.
• Number of Embryos: Thai law limits the number of embryos transferred per cycle to no more than two, and PGT-A genetic screening is required to reduce the risk of chromosomal abnormalities associated with advanced maternal age.

3. 2026 cost reference for IVF surrogacy in Thailand at age 40

The total cost of IVF surrogacy in Thailand at age 40 varies depending on the institution, medical plan, and legal expenses. Based on 2026 market data, it generally includes the following components:

• Medical Fees: Approximately 300,000 - 500,000 Thai Baht (including ovulation induction, egg retrieval, embryo culture, PGT screening, transfer, etc.).
• Surrogate Compensation: For relative surrogacy, only medical and nutritional expenses are usually paid, amounting to about 150,000 - 250,000 Thai Baht.

4. Success rates and hospital selection for IVF surrogacy in Thailand at age 40

If the egg source comes from a young donor, the success rate can exceed 60%.
