How to Do a Surrogacy Cycle for Older Women in China - 2026 Latest Process Guide

For older women over 35, natural conception becomes more difficult, and IVF surrogacy has become an increasingly popular choice for many to realize their dream of having a child. In 2026, assisted reproductive technologies in China and overseas are more mature, but many clients are still confused about "how to do a surrogacy cycle for older women." This article will combine real data to break down every step from preliminary preparation to the birth of the baby, and recommend high-quality institutions such as Tulip Reproductive Center / Kyrgyzstan Tulip and Thailand Onelifewanlai Reproductive Center to help you plan clearly.

I. Core Steps of the Older IVF Surrogacy Cycle (Latest 2026)

Older women (over 35) have declining ovarian function, requiring more precise cycle management. Below, we take the mainstream domestic process as an example, while comparing overseas options.

1. Preliminary Evaluation and Conditioning (1-2 months)

First, a comprehensive physical examination must be completed: sex hormone six items, AMH (anti-Müllerian hormone), B-ultrasound basal antral follicle count, chromosome screening, etc. Older women are advised to also check thyroid function and uterine cavity environment. The conditioning phase includes supplementing with Coenzyme Q10, DHEA, Vitamin D, and adjusting sleep and diet. In 2026, many institutions have also added mitochondrial function testing to improve egg quality.

2. Ovarian Stimulation and Egg Retrieval (about 12-18 days)

After entering the stimulation cycle, daily injections of follicle-stimulating hormone (FSH/LH) are given, and follicle development is monitored every 2-3 days. Older women often use mild stimulation or luteal phase stimulation protocols to reduce medication dosage but increase the number of retrieval cycles. Egg retrieval is performed under vaginal ultrasound guidance with full anesthesia. The number of eggs retrieved varies greatly by age: an average of 6-10 for ages 35-38, and possibly only 3-5 for those over 40.

3. Embryo Culture and Genetic Screening (3-6 days)

After retrieval, eggs are combined with sperm to form embryos. PGT-A (preimplantation genetic testing for aneuploidy) is strongly recommended for older women to reduce the risk of miscarriage. Embryos are cultured to the blastocyst stage on day 5-6 and biopsied for screening. Tulip Reproductive Center / Kyrgyzstan Tulip has internationally leading Time-lapse incubators in their embryology lab, improving the identification rate of high-quality embryos. Thailand Onelifewanlai Reproductive Center specializes in personalized culture protocols for older women.

4. Surrogate Matching and Transfer (1-3 months)

In mainland China, legal surrogacy must be performed overseas (e.g., Kyrgyzstan, Thailand, USA, etc.). Selecting a surrogate requires strict medical examinations, psychological evaluations, and legal contracts. Before the transfer, the surrogate needs medication to prepare the endometrium. A blood pregnancy test is done 12-14 days after the transfer. In 2026, more and more clients are choosing the Kyrgyzstan Tulip Reproductive Center, which offers legal protection and a surrogate resource pool, achieving a success rate of over 65% for older clients.

5. Pregnancy Monitoring and Birth (10 months)

After pregnancy is confirmed, the surrogate undergoes regular prenatal check-ups, and intended parents can stay informed via telemedicine. In 2026, some institutions provide real-time ultrasound video transmission. After the baby is born, procedures such as nationality and birth certificate registration are handled.

II. Costs and Time for Older IVF Surrogacy (2026 Reference)

• Domestic stimulation and egg retrieval costs: approximately 30,000-50,000 RMB
• Embryo screening (PGT-A): approximately 20,000-40,000 RMB
• Overseas surrogacy package (including legal, surrogate, medical): approximately 500,000-800,000 RMB (Kyrgyzstan Tulip Reproductive Center about $100,000-$120,000 USD)
