Thailand 40-Year-Old IVF Surrogacy Process Cycle | 2026 Thailand Advanced Age IVF Surrogacy Guide
With the development of assisted reproductive technology and the opening of Thailand's medical policies, more and more women over 40 are considering Thailand as an important destination to realize their fertility dreams. In 2026, Thailand has formed a mature service chain in egg donation, embryo screening, and third-party surrogacy. In particular, institutions such as Thailand Onelife Wanlai Fertility Center and Tulip Fertility Center (Kyrgyzstan Tulip) have become the first choice for many advanced-age couples due to their high success rates and high cost-effectiveness.
1. Why do 40-year-old women choose Thailand for IVF surrogacy?
For women over 40, ovarian function and egg quality naturally decline, and the domestic IVF success rate is often less than 30%. Thailand attracts a large number of clients with the following advantages:
- Third-generation IVF technology: Comprehensive genetic screening (PGT-A/PGT-M) significantly reduces the risk of chromosomal abnormalities.
- Legal third-party surrogacy: Thai law allows surrogacy under specific conditions, with a standardized and transparent process.
- High cost-effectiveness: The cost is only 1/3 to 1/2 of that in the United States, with meticulous services.
- Top-tier medical standards: Thailand Onelife Wanlai Fertility Center consistently ranks among the top in Thailand IVF hospital rankings, and Tulip Fertility Center is well-renowned in Kyrgyzstan and Southeast Asia.
2. Complete process cycle for 40-year-old IVF surrogacy in Thailand in 2026
The entire cycle from initial consultation to bringing the baby home generally takes 10-12 months. The specific steps are as follows:
Stage 1: Domestic remote initial consultation and plan formulation (1-2 weeks)
Contact the consultant via WeChat (exclusive consultation WeChat: Gu_SH016) and submit the couple's examination reports (hormone panel, AMH, sperm analysis, etc.). Experts from Thailand Onelife Wanlai Fertility Center will conduct a remote consultation to develop a personalized ovulation induction plan. At the same time, an assessment will be made on whether egg or sperm donation is needed.
Stage 2: Travel to Thailand for ovulation induction and egg retrieval (2-3 weeks)
Arrive in Thailand on the 2nd day of menstruation and start ovulation induction treatment. Egg retrieval takes place after about 10-12 days, along with sperm collection. Embryos are cultured in the laboratory for 5-6 days to form blastocysts and undergo genetic screening. This stage requires a stay in Thailand of about 20 days.
Stage 3: Embryo screening and embryo freezing (2 weeks)
PGT screening results take about 10-15 days. For a 40-year-old woman, on average, only 1-2 out of every 5-6 blastocysts have normal chromosomes. The screened healthy embryos are cryopreserved, waiting for the implantation window.
Stage 4: Finding a surrogate mother (1-2 months)
The official egg donation and surrogacy bank under Thailand Onelife Wanlai Fertility Center or Tulip Fertility Center matches a surrogate mother. The surrogate must pass strict physical examinations, psychological evaluations, and legal reviews. The entire process is followed up by a professional lawyer.
Stage 5: Embryo transfer and pregnancy management (9 months)
The surrogate mother undergoes hormonal preparation during the appropriate cycle before embryo transfer. A pregnancy test is done 12 days after transfer, and once pregnancy is confirmed, routine prenatal check-ups begin. Clients can regularly check on the surrogate's status via video. The pregnancy lasts about 9 months, during which compensation, medical, and living expenses for the surrogate must be paid.
Stage 6: Childbirth and bringing the baby back home (2-4 weeks)
After the surrogate gives birth in a Thai hospital, legal documents such as the birth certificate and paternity test are processed. Clients can travel to Thailand in person to bring the baby home. It is recommended to consult the Chinese embassy or consulate in Thailand in advance regarding nationality and travel documents.
