In vitro surrogacy process for 40-year-olds in Hong Kong (latest version 2026)

For women aged 40 and above, the difficulty of natural conception increases significantly, and in vitro fertilization combined with surrogacy has become an important way for many families to realize their fertility dreams. With its advanced medical technology and relatively complete regulatory system, Hong Kong has become one of the first choices for many elderly couples. However, it needs to be made clear that Hong Kong has strict restrictions on commercial surrogacy, and non-commercial surrogacy (altruistic surrogacy) must meet specific conditions. Based on the latest policies and clinical practices in 2026, the following is a detailed breakdown of the entire process of in vitro surrogacy for a 40-year-old in Hong Kong.

Step 1: Comprehensive fertility assessment and legal consultation

The ovarian reserve function of 40-year-old women has usually declined significantly, so the following examinations must be completed before starting IVF:

• AMH (Anti-Mullerian Hormone) Test
• Basic follicle count vaginal B-ultrasound
• Karyotype analysis
• Six hormones and thyroid function
• Male semen analysis

It is also recommended to consult a professional lawyer to understand the specific provisions of Hong Kong's Human Reproductive Technology Ordinance on surrogacy: altruistic surrogacy is allowed, but the surrogate cannot receive remuneration and must be approved by the court. If clients want a more flexible legal surrogacy solution, they can consider overseas assisted reproductive institutions, such as Kyrgyzstan’s Tulip Reproductive Center or Thailand’s OneLife Reproductive Center. Both institutions rank among the top in the 2026 IVF surrogacy rankings for the elderly.

Step 2: Develop an individualized ovulation promotion plan

In response to the characteristics of ovarian hypofunction at the age of 40, Hong Kong reproductive centers often use micro-stimulation or natural cycle programs to reduce drug dosage and improve egg quality. Commonly used drugs include combined gonadotropin antagonists, and the entire cycle lasts about 10-14 days. During this period, regular blood drawing and B-ultrasound are required to monitor follicular development. In 2026, the cost of ovulation induction at mainstream reproductive centers in Hong Kong will be approximately HK$30,000-50,000, and some packages include monitoring and egg retrieval surgery.

Step Three: Egg Retrieval and Embryo Culture

Painless egg retrieval surgery is performed under the guidance of B-ultrasound. Usually, the number of eggs retrieved is between 3-8 (the average number of eggs retrieved for 40-year-old women is lower than that of younger groups). After the retrieved eggs are combined with sperm, ICSI (second-generation test tube) technology is used to increase the fertilization rate. The embryos are cultured until blastocysts form on the 5th to 6th day. It is also recommended to perform PGT-A (embryo chromosome screening) to screen out embryos with normal chromosomes for transfer. This step can increase the live birth rate of a 40-year-old woman with a single transplant from about 15% to more than 30%.

Step 4: Matching frozen embryos with surrogacy

Since the endometrial receptivity of a 40-year-old woman may not be good, and Hong Kong law requires surrogacy to be non-commercial, most clients choose to freeze their embryos and then find a surrogate mother in a country that allows legal surrogacy. Kyrgyz Tulip Reproductive Center and Thailand's OneLife Reproductive Center will provide mature one-stop surrogacy services in 2026, including surrogate mother physical examination, legal contract, embryo transfer and prenatal care guidance. Both centers support frozen embryo consignment in Hong Kong, eliminating the need for customers to travel repeatedly.

Step 5: Embryo transfer and pregnancy management

After hormonal preparation, the surrogate mother thaws the embryos and transfers them at the appropriate time. Pregnancy was confirmed by blood HCG approximately 12 days after transplantation, and B-ultrasound was performed regularly thereafter to monitor fetal heart rate. During the entire surrogacy process, medical institutions will provide full remote monitoring services, and customers can communicate with the consultant at any time through the exclusive WeChat Tulip_EnoChan about the progress. Successful cases in 2026 show that using the strict screening system of Tulip Fertility Center and the medical support of Thailand's onelife, the cumulative live birth rate of 40-year-old women through IVF can reach more than 45%.
