For families in China with fertility needs at the age of 45, surrogacy has become an important reproductive pathway. In 2026, with the continuous advancement of assisted reproductive technology, the process for 45-year-old women to achieve pregnancy through surrogacy has become clearer and the cycle more controllable. This article will comprehensively present every aspect of the surrogacy process cycle for 45-year-old Chinese clients from dimensions such as medical evaluation, legal preparation, cycle planning, and cost composition, helping you make more rational decisions.
I. Medical Basis and Feasibility of Surrogacy at Age 45
Ovarian function in 45-year-old women enters a rapid decline phase, with extremely low natural conception rates and significantly decreased egg quality. By 2026, assisted reproductive technology has been able to maximize the selection of healthy embryos for surrogacy through precise endocrine regulation, personalized ovarian stimulation protocols, and third-generation IVF PGT-A chromosomal screening technology. Although the success rate of using one's own eggs at age 45 is lower compared to younger women, a considerable proportion of families can still obtain healthy embryos through professional reproductive center evaluation and intervention.
For 45-year-old women with severely declined ovarian function, using donor eggs combined with the husband's sperm for surrogacy can significantly increase the success rate to 60% to over 75%. By 2026, whether through the own-egg or donor-egg path, the medical process for surrogacy at age 45 is very mature. The key lies in choosing a professional institution and strictly following the cycle.
II. Detailed Breakdown of the Complete Surrogacy Process Cycle for 45-Year-Olds in 2026
The complete surrogacy process cycle for a 45-year-old typically takes 10 to 14 months, mainly divided into the following stages:
Stage 1: Preliminary Consultation and Medical Evaluation (Approximately 2 to 4 Weeks)
The core of this stage is a comprehensive assessment of the 45-year-old client's physical condition. Required tests include: Anti-Müllerian Hormone (AMH) test, baseline antral follicle count ultrasound, hormone panel six, thyroid function, infectious disease screening, and chromosomal karyotype analysis. Additionally, the client needs to provide a detailed history of previous fertility and surgeries. After the medical evaluation, the reproductive specialist will provide personalized plan recommendations, clearly indicating whether to use own eggs or donor eggs. This stage also requires psychological evaluation and legal consultation to ensure the client has a full understanding and preparation for the surrogacy process.
Stage 2: Ovarian Stimulation and Egg Retrieval (Approximately 2 to 3 Weeks)
For 45-year-old women choosing to use their own eggs, the doctor will formulate an ovarian stimulation plan based on the evaluation results. Commonly used protocols in 2026 include the mild stimulation protocol, antagonist protocol, and luteal phase protocol. These protocols are more suitable for advanced-age women and can reduce the risk of ovarian hyperstimulation. During ovarian stimulation, follicle development needs to be monitored regularly, typically for 10 to 14 days. The egg retrieval surgery is performed under anesthesia, taking about 15 to 20 minutes. After the retrieval, rest for 1 to 2 days is sufficient to return to normal life.
Stage 3: Embryo Culture and Genetic Screening (Approximately 4 to 6 Weeks)
After egg retrieval, the eggs are combined with sperm to form embryos, which are cultured in the laboratory to the blastocyst stage on day 5 or 6. For 45-year-old clients, third-generation IVF PGT-A chromosomal screening is a necessary step. It can screen embryos for chromosomal abnormalities, significantly improving the transfer success rate and reducing the risk of miscarriage. Screening results are usually available within 2 to 3 weeks.
Stage 4: Surrogate Matching and Legal Preparation (Approximately 4 to 8 Weeks)
While embryos are being prepared, the screening and matching of a surrogate can proceed simultaneously. By 2026, the screening criteria for surrogates have become stricter, including age typically between 25 and 35, at least one healthy full-term delivery history, comprehensive physical and psychological evaluations, and no infectious or genetic diseases. After a successful match, both parties sign a legal agreement clarifying rights and obligations, compensation plans, and risk-sharing mechanisms.
Stage 5: Embryo Transfer and Pregnancy Confirmation (Approximately 4 to 6 Weeks)
The surrogate needs to prepare her endometrium, using hormone replacement therapy to achieve optimal endometrial thickness and pattern. The embryo transfer procedure is performed under ultrasound guidance and is simple and quick. About 10 to 12 days after the transfer, pregnancy can be confirmed by a blood test for HCG. An ultrasound examination is performed 4 to 6 weeks after the transfer to confirm the fetal heartbeat and yolk sac.
Stage 6: Pregnancy Management and Delivery (Approximately 36 to 40 Weeks)
After pregnancy is confirmed, the surrogate enters a standardized pregnancy management phase, with regular prenatal check-ups and health monitoring. The 45-year-old client can track the pregnancy progress in real-time through a telemedicine platform. Delivery usually occurs at 39 to 40 weeks, and the client can choose to be present during the delivery.
III. 45-Year-Old Surrogacy Timeline
To help 45-year-old clients visualize the surrogacy cycle more intuitively, here is a typical timeline:
Months 1 to 2: Complete medical evaluation, plan formulation, legal consultation, and surrogate matching.
Month 3: Ovarian stimulation, egg retrieval, embryo culture, and genetic screening.
Months 4 to 5: Surrogate endometrial preparation and embryo transfer.
Months 5 to 6: Pregnancy confirmation and early pregnancy support.
Months 6 to 10: Pregnancy management and regular prenatal check-ups.
Months 10 to 14: Delivery preparation and baby's birth.
It is important to note that the time for each step may vary due to individual differences, institutional procedures, and unforeseen circumstances. In 2026, many professional institutions offer expedited services, which can shorten the overall cycle to some extent.
IV. Analysis of 45-Year-Old Surrogacy Costs
