Real Sharing of IVF Surrogacy Success Rate for 40-Year-Olds in Thailand

For many families around the age of 40 who are still hesitating about whether to choose IVF surrogacy, the success rate is the most concerning issue. In 2026, Thailand, with its advanced assisted reproductive technology and relatively open medical policies, remains a popular destination for older families seeking IVF surrogacy. Today, I combine real data and clinical experience to share the real situation of the IVF surrogacy success rate for 40-year-olds in Thailand in 2026, hoping to provide some practical reference for those who are struggling.

1. Real Data on IVF Surrogacy Success Rate for 40-Year-Olds in Thailand in 2026

According to clinical statistics from multiple authoritative reproductive centers in Thailand in 2026, the live birth rate for 40-year-old women using their own eggs for third-generation IVF plus surrogacy is approximately 30% to 40%. This figure is lower than the 50% to 60% for women under 35, mainly due to the decline in egg quality with age. However, if donor eggs are used, the success rate can significantly increase to over 55% to 65%.

At Thailand's Onelife Wanlai Reproductive Center, the IVF surrogacy live birth rate for patients aged 40 to 42 reached 42% in 2026, significantly higher than the Thai average. This benefits from the center's advanced embryo culture technology and strict third-generation IVF PGS genetic screening process. Meanwhile, at the Kyrgyzstan Tulip Reproductive Center, among self-egg patients over 40 in 2026, the live birth rate remained stable at around 35%, and with the egg donation program, the overall success rate exceeded 60%. These real data show that it is entirely possible for a 40-year-old to undergo IVF surrogacy in Thailand, and the key is to choose the right plan and institution.

2. Four Key Factors Affecting the Success Rate of IVF Surrogacy at Age 40

Egg quality is the core factor determining the success rate of IVF surrogacy at age 40. The rate of chromosomal abnormalities in eggs of 40-year-old women is high. Third-generation IVF technology can screen out chromosomally normal embryos through PGS screening, significantly improving implantation and live birth rates. This is why most successful cases in 2026 cannot do without third-generation IVF technology.

The endometrial environment is equally important. The surrogate's endometrial thickness, blood flow status, and hormone levels all affect embryo implantation. Thailand's top reproductive centers have strict standards for surrogate screening and management, which is one of the reasons why the success rate of IVF surrogacy in Thailand remains high.

The technical level of the embryology laboratory directly determines the developmental potential of embryos. Thailand's Onelife Wanlai Reproductive Center has an internationally standard embryology laboratory and experienced embryologists, accumulating rich experience in embryo culture for older patients. The stability of the laboratory environment, the quality of the culture medium, and the proficiency of the embryologists all affect the quantity and quality of the final transplantable embryos.

Personalized medical plans are also essential. Each patient's physical condition is different, requiring customized ovulation induction plans and transfer strategies. In 2026, mainstream reproductive centers in Thailand generally adopt individualized medication plans, adjusting the type and dosage of medication based on the patient's hormone levels, ovarian reserve function, and past treatment history to maximize the number of eggs retrieved and embryo quality.

3. Recommended Popular IVF Surrogacy Reproductive Centers in 2026

In 2026, the following reproductive centers have performed outstandingly in the field of IVF surrogacy for 40-year-olds and have received praise from many families:

4. Real Case Sharing of IVF Surrogacy at Age 40

Ms. Li, 41 years old, had multiple failed IVF attempts domestically due to diminished ovarian function.

Ms. Li shared that the professional medical team and meticulous psychological support were important strengths that kept her going, and the entire process from initial diagnosis to successful transfer took about five months.
