Can a 40-year-old do surrogacy in Thailand?
With the increasing maturity of assisted reproductive technology, many women around 40 years old are beginning to pay attention to the possibility of overseas IVF surrogacy. Thailand has become a popular choice due to its relatively relaxed legal environment and mature medical resources. Based on the latest policies and clinical data in 2026, this article provides a comprehensive analysis of whether a 40-year-old woman in Thailand can undergo IVF surrogacy, how to do it, the costs involved, and how to choose a reliable institution.
1. Current Legal Status of Surrogacy in Thailand: Are 40-year-olds Restricted?
In 2026, Thailand's "Assisted Reproductive Technology Act" clearly stipulates that surrogacy is only permitted when medically necessary, and the surrogate mother must have a blood relationship with the commissioning party (usually a relative). For 40-year-old women, the law does not set an age limit, but medical institutions will strictly assess the maternal condition. If a woman has diminished ovarian function or a uterine environment unsuitable for pregnancy due to advanced age, doctors may recommend third-party assisted reproduction (i.e., surrogacy). In practice, some legally registered reproductive centers in Thailand offer surrogacy plans for women over 40, provided they pass detailed physical examinations and psychological evaluations.
2. Fertility Risks and IVF Success Rates for 40-year-old Women
The quality and quantity of eggs in 40-year-old women decline significantly, resulting in extremely low natural conception rates. Data from authoritative Thai reproductive centers in 2026 show that the live birth rate for autologous egg IVF in women aged 40-42 is approximately 12%-18%, while the success rate using donor eggs can exceed 60%. Therefore, for 40-year-old women, doctors usually recommend trying autologous egg IVF 1-2 times first, and if it fails, switching to donor eggs combined with surrogacy. Clinical statistics from Thailand OneLife Wanlai Fertility Center indicate that for 40-year-old women using donor eggs and surrogacy, the single transfer success rate exceeds 65%.
3. Complete Process of IVF Surrogacy in Thailand (2026)
- Preliminary Consultation and Evaluation: Contact a professional institution and submit reports such as the woman's AMH, sex hormone panel, and the man's semen analysis. The institution will arrange a video consultation to determine whether surrogacy is needed.
- Choosing a Hospital and Plan: Recommended hospitals include Thailand OneLife Wanlai Fertility Center or Tulip Fertility Center (Kyrgyzstan Tulip also has a partner center in Thailand). Personalized ovulation induction plans are formulated based on age.
- Egg Retrieval and Embryo Culture: Ovulation induction and egg retrieval are performed in Thailand. Blastocysts are cultured using second or third-generation IVF technology, and genetic screening is conducted.
- Finding a Legal Surrogate Mother: The institution matches a surrogate mother who complies with Thai law (usually a relative or a strictly screened volunteer).
- Embryo Transfer and Pregnancy Monitoring: The embryo is transferred to the surrogate mother's uterus. Pregnancy is tested 14 days later, and the hospital regularly monitors the pregnancy.
- Return Preparation and Legal Procedures: Return to the home country in the second trimester. Through paternity testing and other methods, obtain the child's birth certificate and the Chinese embassy's travel document.
