III. Detailed Process of Advanced Age Surrogacy in Thailand in 2026
- Preliminary consultation and medical evaluation: Provide recent medical reports. The Thai fertility center will assess ovarian reserve, uterine conditions, genetic risks, etc., to determine suitability for advanced age surrogacy.
- Selection of surrogacy agency and legal对接: Confirm a legal intermediary or assisted reproduction center, sign a bilateral legal contract clarifying the rights and obligations of the surrogate mother and cost details.
- Medical operation phase: Undergo ovarian stimulation, egg retrieval, sperm processing, embryo culture (usually 5-6 days) and PGT screening for normal embryos in Thailand.
- Embryo transfer: Select healthy blastocysts for transfer into the surrogate mother's uterus. Blood test 10-12 days after transfer to confirm pregnancy.
- Pregnancy management and birth: The surrogate mother undergoes regular prenatal check-ups in Thailand. After the baby is born, handle birth certificate, DNA paternity test, and documents for returning to home country.
The entire cycle requires approximately 4-5 trips to Thailand, each lasting 10-20 days. Older women need to prepare their bodies before egg retrieval, and it is recommended to start taking Coenzyme Q10, Vitamin D, etc., 2-3 months in advance.
IV. Success Rate and Key Influencing Factors for Advanced Age Surrogacy in Thailand
In 2026, the live birth rate for advanced age IVF at top Thai fertility centers can reach 40%-55% (for women aged 40-45 using their own eggs). The success rate is even higher when using donor eggs. Core factors affecting success include:
- Female age: The rate of chromosomal abnormalities in eggs increases significantly after age 40; it is recommended to proceed as early as possible.
- Ovarian reserve function: Success rates are more reliable when AMH value is ≥1.0 ng/mL; lower values may require considering egg donation.
- Uterine environment: The health of the surrogate mother's uterus directly affects the implantation rate.
- Embryo chromosomal integrity: PGT screening can improve transfer efficiency and reduce the risk of miscarriage.

VI. Frequently Asked Questions about Advanced Age Surrogacy in Thailand
Q1: Is there an age limit for advanced age surrogacy in Thailand in 2026?
Thai law does not explicitly stipulate an age limit, but most fertility centers will evaluate women's AMH, FSH, etc. If AMH is extremely low or ovarian failure has occurred, using donor eggs is recommended. The success rate of natural cycle IVF with own eggs for women over 45 is extremely low and requires careful evaluation.
Q2: How can a child born through surrogacy in Thailand obtain Chinese nationality?
According to the Chinese Nationality Law, if both parents or one parent is a Chinese citizen and the child is not residing abroad at birth, the child can apply for Chinese nationality. Required documents include a DNA paternity test report, birth certificate, parents' passports, etc. Apply for a travel document or passport at the Chinese Embassy in Thailand, and register household registration after returning to China.
Q3: Can the cost of advanced age surrogacy be paid in installments?
Most Thai institutions support phased payments, such as an initial deposit, payment before medical procedures, payment after successful transfer, etc. Specific terms should be agreed upon in the contract with the institution. It is recommended to choose an agency with a supervised account to ensure fund security.
Q4: How is the background of surrogate mothers screened?
Reputable institutions strictly screen surrogates: age 25-35, have given birth to healthy children, no genetic disease history, and pass psychological evaluation. In 2026, Thai surrogates must undergo background checks and multiple physical exams to ensure physical and mental health.
Q5: If the first transfer fails, how are the costs calculated?
Most packages include the cost of one transfer. If it fails, subsequent transfers require additional payment for embryo thawing and transfer fees. For older women, it is recommended to undergo endometrial receptivity testing before transfer to improve implantation rates.
