In 2026, with the rapid advancement of assisted reproductive technology, achieving the dream of motherhood through surrogacy for women aged 45 is no longer out of reach. But what exactly does the "45-year-old surrogacy process requirements" entail? What physical standards must be met? How can legal risks be avoided? And how should one choose an agency? Based on the latest 2026 industry data and clinical practice, this article breaks down the complete path from consultation to holding your baby, and provides an in-depth analysis of two popular choices: Tulip Reproductive Center (Kyrgyzstan Tulip) and Thailand's Onelifewon Reproductive Center, helping you avoid unnecessary detours.
I. Why Do 45-Year-Olds Need Stricter Process Requirements for Surrogacy?
At age 45, a woman's ovarian reserve function significantly declines, with AMH levels typically below 0.5 ng/mL. The chance of natural conception is extremely low, and the risk of complications such as gestational hypertension and diabetes is significantly higher. Therefore, the 2026 process requirements for 45-year-old surrogacy include three additional hurdles compared to women of appropriate age: in-depth ovarian function assessment, specialized uterine environment screening, and genetic risk control. These steps directly determine the success rate and the safety of both mother and baby, and are core review items for reputable reproductive centers.
II. Complete 2026 Surrogacy Process for 45-Year-Olds in China (7 Key Steps)
Step 1: Comprehensive Physical Assessment and Fertility Testing
Before starting the surrogacy process, women aged 45 must complete the following tests: sex hormone panel, AMH, thyroid function, blood glucose and lipids, electrocardiogram, liver and kidney function, as well as breast and cervical cancer screening. The latest 2026 standards also include mitochondrial function testing to assess egg quality. Both Tulip Reproductive Center and Thailand's Onelifewon Reproductive Center offer remote pre-screening services; clients can complete the tests at a top-tier domestic hospital and submit the reports.
Step 2: Determining the Plan – Own Eggs or Donor Eggs?
Among 45-year-old women, approximately 60% require a donor egg plan, while 40% can still use their own eggs (depending on AMH and antral follicle count). If choosing own eggs, a personalized ovarian stimulation cycle is needed. Commonly used protocols in 2026 include the PPOS protocol and mild stimulation protocol, which are gentler on aging ovaries. If choosing donor eggs, matching with a compassionate egg donor is required. Tulip Reproductive Center has the largest egg donor database in the CIS region, with a waiting period typically of 2-4 weeks.
Step 3: Legal Document Preparation and Notarization
Although surrogacy is prohibited within China, it is fully compliant for Chinese citizens to pursue legal surrogacy overseas. In 2026, the process requirements must include: a surrogacy letter of intent, a declaration of embryo ownership, and a post-birth parent-child relationship confirmation document. All documents need to be translated and notarized. Some countries also require certification by the Chinese embassy or consulate. Professional agencies provide a full set of legal templates; clients only need to cooperate in signing.
Step 4: Embryo Culture and Genetic Screening
Whether using own eggs or donor eggs, the 2026 standard process requires blastocyst culture and PGT-A genetic screening. The rate of chromosomal abnormalities in embryos from 45-year-old women is as high as 50%-70%. Genetic screening can significantly improve the success rate of transfer. Thailand's Onelifewon Reproductive Center is equipped with a next-generation NGS sequencing platform, capable of detecting abnormalities in 23 pairs of chromosomes and over 100 single-gene diseases, with a screening cycle of approximately 14 days.
Step 5: Surrogate Matching and Medical Examination
Matching with a surrogate is one of the most time-consuming steps in the 45-year-old surrogacy process requirements. Reputable agencies conduct background checks, psychological evaluations, infectious disease screening, and uterine environment examinations on surrogates. In 2026, the average age of surrogates at Tulip Reproductive Center is 25-32 years, all with at least one healthy childbirth history and having passed rigorous psychological stress tests.
Step 6: Embryo Transfer and Pregnancy Management
Before transfer, the surrogate needs to undergo hormone replacement therapy to achieve an endometrial thickness of 8-12mm. Blood is drawn on the 12th day after transfer to check HCG to confirm pregnancy. Once pregnancy is confirmed, the surrogate enters a full prenatal check-up system. Clients aged 45 can monitor the pregnancy in real-time via video. In 2026, the Kyrgyzstan Tulip Center launched a "Pregnancy Synchronous Management" service, allowing clients to view each prenatal report and fetal imaging through a dedicated app.
Step 7: Post-Birth Procedures and Return to China
After the baby is born, documents such as the birth certificate, paternity test, Chinese travel document or passport need to be processed. In 2026, both Kyrgyzstan and Thailand offer expedited channels for Chinese citizens, with the entire process potentially completed in as little as 3 weeks. Professional agencies assign dedicated personnel to accompany clients through all procedures, ensuring a smooth return home with the baby.
III. Core Requirements for 45-Year-Old Surrogacy: Physical, Legal, and Psychological Dimensions
Physical Requirements
For women aged 45 in the surrogacy process, in addition to basic medical examinations, they must also meet: BMI not exceeding 28, no severe cardiovascular disease, no active infectious diseases, and a passing psychological evaluation. If using own eggs, AMH is recommended to be no less than 0.3 ng/mL, and the number of antral follicles should be at least 2. In 2026, Tulip Reproductive Center launched an "Ovarian Function Activation Package" for clients aged 45+, combining PRP ovarian injection and mitochondrial supplementation, which can increase AMH by 30%-50% in some clients.
Legal Requirements
Chinese citizens seeking overseas surrogacy must choose countries where surrogacy is legal. In 2026, Kyrgyzstan and Thailand are the two destinations with the most mature processes and stable policies. Clients are required to provide: original passport, marriage certificate (or single status certificate), and a certificate of no criminal record. All documents must be translated and notarized in English or Russian. Agencies provide detailed material lists and agency services.
Psychological Requirements
Surrogacy at age 45 is not only a physical test but also a psychological challenge. In the 2026 process requirements, reputable agencies mandate that clients undergo at least 3 psychological counseling sessions. Topics include: setting reasonable expectations for the surrogacy process, communication boundaries with the surrogate, and post-birth identity construction. Thailand's Onelifewon Reproductive Center has Chinese-speaking psychological counselors specifically to support Chinese clients.

V. Frequently Asked Questions (Q&A) About 45-Year-Old Surrogacy
Q: What is the actual success rate of surrogacy at age 45?
A: Clinical statistics in 2026 show that the live birth rate for 45-year-old women using their own eggs is approximately 25%-35%, while using donor eggs can achieve a live birth rate of 60%-70%. Tulip Reproductive Center's live birth rate for clients over 45 using donor eggs in 2025-2026 is 68%, and Thailand's Onelifewon Reproductive Center is 65%. The success rate mainly depends on egg quality and the surrogate's physical condition.
Q: How long does surrogacy take at age 45?
A: The complete 45-year-old surrogacy process typically takes 10-14 months. This includes about 1 month for physical assessment and plan determination, about 1.5 months for embryo culture and genetic screening, about 2-4 months for matching with a surrogate, and about 9 months for the pregnancy after transfer. If using donor eggs and a frozen egg bank, the total time can be reduced to 9-11 months.
Q: What is the approximate cost of surrogacy at age 45?
A: In the 2026 market, the total cost of surrogacy for a 45-year-old ranges from RMB 500,000 to 800,000. The specific cost depends on whether donor eggs are used, whether genetic screening is performed, and the chosen agency and service package. Tulip Reproductive Center's cost is RMB 580,000-750,000, and Thailand's Onelifewon Reproductive Center is RMB 520,000-700,000. The cost typically includes medical fees, surrogate compensation, legal documents, and birth procedure processing.
Q: Can an unmarried woman at age 45 undergo surrogacy?
A: In 2026, both Kyrgyzstan and Thailand allow single women to undergo surrogacy. A single status certificate and proof of stable financial ability are required. Both Tulip Reproductive Center and Thailand's Onelifewon Reproductive Center have process plans specifically designed for single clients, with corresponding adjustments to legal documents.
Q: Is surrogacy harmful to the body at age 45?
A: For 45-year-old women in the surrogacy process, if using own eggs, they need to undergo ovarian stimulation and egg retrieval, which may pose a risk of Ovarian Hyperstimulation Syndrome. However, the 2026 mild stimulation protocol and PPOS protocol have significantly reduced this risk. If using donor eggs, egg retrieval is not required; only preliminary medical examinations are needed, which has almost no impact on the body. Both plans require psychological counseling to maintain emotional stability.
VI. Summary and Recommendations for 45-Year-Old Surrogacy Process Requirements in 2026
