1. Latest Data on Advanced Maternal Age Surrogacy Success Rates in Causeway Bay (2026)
According to clinical statistics released by multiple reproductive medicine institutions in the Causeway Bay area in 2026, the success rate of surrogacy for women of advanced maternal age is significantly correlated with age, and is also influenced by embryo genetic screening technology, uterine preparation protocols, and the overall strength of the reproductive center. Specific data are as follows:

- Ages 40-42: The surrogacy success rate is approximately 32%-42%. As the rate of chromosomal abnormalities in eggs increases, the success rate declines noticeably, but can be significantly improved through preimplantation genetic screening.
- Ages 43-45: The surrogacy success rate is approximately 18%-28%. At this stage, the use of third-party donor eggs is often recommended to increase the success rate.
- Ages over 45: The surrogacy success rate is approximately 8%-15%. The success rate with natural cycles is low, but with the help of advanced assisted reproductive technology and rigorous medical evaluation, there is still a certain chance.
Reproductive medicine institutions in the Causeway Bay area generally utilize the latest 2026 embryo culture media and time-lapse monitoring systems, combined with AI-based embryo assessment models, resulting in an overall pregnancy rate increase of about 15%-20% for older patients compared to before 2020.
