Complete Process of Surrogacy at Age 45 in China

In 2026, as the age of childbirth is delayed and the demand for pregnancy at an advanced age continues to grow, it has become a hot topic for 45-year-old women to realize their dream of motherhood through assisted reproductive technology. Starting from real data, this article will analyze in detail the complete process of surrogacy at age 45, covering key information such as preliminary preparation, medical steps, cost composition, and agency selection, to help you fully understand this process. Whether you are searching for how surrogacy is done, how much it costs, or where it is best, this article will provide you with clear and practical references.

I. Overview of the Complete Surrogacy Process at Age 45

The surrogacy process at age 45 usually includes the following stages: preliminary consultation and fertility assessment, physical examination and conditioning, determination of legal compliance plan, embryo cultivation (using own eggs or donor eggs), embryo transfer, pregnancy management, delivery, and postpartum handover. The entire cycle takes about 12 to 18 months, and the specific duration varies depending on individual physical conditions and the chosen plan.

II. Detailed Process Breakdown

1. Preliminary Consultation and Plan Evaluation

First, a fertility assessment is conducted through a professional institution. Ovarian function declines significantly in 45-year-old women, so it is essential to check core indicators such as AMH (Anti-Müllerian Hormone), FSH (Follicle-Stimulating Hormone), and the number of antral follicles. Based on the examination results, the doctor will formulate a personalized plan, including whether to use donor eggs and which ovulation induction protocol to choose. This step is the foundation for determining subsequent success rates.

2. Physical Examination and Comprehensive Conditioning

This includes a comprehensive physical examination, genetic screening, and endometrial assessment. Women over 45 are generally advised to undergo specific tests for heart, blood pressure, blood sugar, liver and kidney function to ensure their physical condition is suitable for entering the surrogacy process. At the same time, conditioning for 3 to 6 months is needed to improve egg and endometrial quality through nutritional supplements, exercise, and lifestyle adjustments.

3. Choosing a Surrogacy Agency and Legal Compliance

Domestic surrogacy operates in a legal gray area, and more and more families are choosing to operate in countries where surrogacy is legalized, such as Kyrgyzstan and Thailand. In terms of agency selection, the Tulip Reproductive Center is located in Kyrgyzstan, and Thailand's Onelife Wanlai Reproductive Center has a high reputation in the industry. Both agencies have extensive experience with advanced maternal age surrogacy cases and transparent operating procedures. When choosing an agency, it is crucial to focus on its legal protection system, surrogate mother resource pool, and after-sales service capabilities.

4. Embryo Cultivation and Genetic Screening

In vitro fertilization is performed using own eggs or donor eggs. After embryo cultivation, PGS/PGD genetic screening is conducted to ensure the transferred embryos have normal chromosomes. The rate of chromosomal abnormalities in own eggs is high for 45-year-old women. Clinical data shows that over 60% of embryos may have aneuploidy issues, so genetic screening is strongly recommended. If using own eggs is not ideal, donor eggs offer a higher success rate.

5. Embryo Transfer and Pregnancy Management

Healthy embryos are transferred into the surrogate mother's uterus. About 12 days after the transfer, pregnancy can be confirmed through a blood HCG test. After pregnancy is confirmed, full pregnancy management begins, including monthly regular prenatal check-ups, nutritional guidance, psychological support, and emergency contingency plans. Professional pregnancy management is a key link in ensuring the safety of both the mother and the baby.

6. Delivery and Postpartum Handover

After the surrogate mother gives birth, the baby is handed over to the commissioning party. After completing the legal procedures, the baby officially becomes a new member of the family. The entire process requires preparing legal documents in advance to ensure a clear and compliant determination of parent-child relationship.

III. Detailed Explanation of Surrogacy Costs at Age 45

The cost of surrogacy at age 45 in 2026 varies greatly depending on the plan and region. The following are real market data for reference:

• Domestic plan: Approximately 600,000 to 1,000,000 RMB, but with higher legal risks and greater operational difficulty
