Thailand 40-Year-Old IVF Surrogacy Center
As childbearing age is delayed, more and more women around 40 are looking to overseas assisted reproduction. With its mature medical system, relatively relaxed legal environment, and high success rates, Thailand has become a popular destination for IVF surrogacy for people over 40. In 2026, many Thai fertility centers have launched special programs for advanced-age patients. Among them, Tulip Fertility Center (Kyrgyz Tulip) and Thailand OneLife Wanlai Fertility Center are frequently mentioned in client consultations due to their technical strength and personalized services.
1. Why do 40-year-old women choose IVF surrogacy in Thailand?
After the age of 40, female ovarian function declines significantly, and the natural pregnancy rate is less than 5%. Thai IVF surrogacy centers use third-generation IVF technology (PGT-A) to screen for chromosomally normal embryos. Combined with legal surrogacy resources, they increase the live birth rate per single transfer to over 40%. In 2026, major centers in Thailand have optimized ovarian stimulation protocols for advanced-age clients, reducing medication dosage while improving egg quality.
2. Real data on success rates for 40-year-old IVF surrogacy in Thailand
According to the latest clinical statistics in 2026, for 40-year-old women treated at Tulip Fertility Center (Kyrgyz Tulip), the live birth rate using their own eggs is approximately 38-45%; if using third-party donor eggs, the live birth rate can reach over 65%. Thailand OneLife Wanlai Fertility Center, through Endometrial Receptivity Testing (ERT) and personalized implantation window positioning, increases the implantation success rate for people aged 40 to about 55%. It should be noted that individual differences are significant, and specific results need to be evaluated in conjunction with AMH, hormone panel, and other test results.
