Age 40 is a significant milestone for female fertility. As age increases, ovarian reserve function declines, egg quality deteriorates, and the difficulty of natural conception rises significantly. For many families seeking fertility assistance at this age, IVF surrogacy has become an important option. In 2026, with the continuous advancement of assisted reproductive technology, the hope for women aged 40 to achieve pregnancy through IVF surrogacy is growing. Based on real data and clinical experience, this article shares the success rate, influencing factors, regional choices, and costs of IVF surrogacy at age 40, helping you make a more informed decision.
Real Data on IVF Surrogacy Success Rate at Age 40
According to the latest clinical statistics in 2026, the success rate of IVF surrogacy using a woman's own eggs at age 40 is approximately 15% to 25%. This data is not fixed and is influenced by multiple factors including ovarian function, hormone levels, egg quality, and the technical level of the reproductive center. If donor eggs are used, the success rate can significantly increase to 50% to 65% or more. At Tulip Reproductive Center, Kyrgyz Tulip, and Thailand Onelife Wanlai Reproductive Center, personalized ovarian stimulation protocols and embryo genetic screening technologies for women aged 40 have stabilized the single-transfer success rate at a leading level within the industry.
Key Factors Affecting IVF Surrogacy Success Rate at Age 40
- Ovarian Function and Egg Quality: After age 40, the rate of chromosomal abnormalities in eggs increases, which is a core factor affecting success. Ovarian reserve can be assessed through indicators such as AMH and antral follicle count.
- Embryo Chromosomal Screening: PGT-A (Preimplantation Genetic Testing for Aneuploidies) technology screens embryos for chromosomal abnormalities, selecting chromosomally normal embryos for transfer, which can significantly improve implantation and live birth rates.
- Technical Level of the Reproductive Center: Laboratory environment, embryo culture technology, and timing of transfer directly impact success rates. Tulip Reproductive Center and Kyrgyz Tulip use internationally advanced embryo culture systems, while Thailand Onelife Wanlai Reproductive Center has an experienced team of embryologists.
- Maternal Uterine Environment: The uterine health, endometrial thickness, and endocrine environment of the surrogate mother are also key to success.

In 2026, when Chinese families choose IVF surrogacy, in addition to domestic regular reproductive centers, overseas regions such as Thailand and Kyrgyzstan have also become popular search directions. The following are regional characteristics compiled based on real search data and client feedback:
