In 2026, assisted reproductive technology continues to break through, and the success rate of achieving pregnancy through surrogacy for 45-year-old women has significantly improved compared to the past. This article provides a comprehensive analysis of the surrogacy success rate, complete process, cost structure, and popular agency choices that are of greatest concern to 45-year-old families in China, helping families in need make clearer decisions.
1. Real Data on Surrogacy Success Rate for 45-Year-Olds
For a 45-year-old woman using her own eggs for surrogacy, the single transfer success rate is approximately 15% to 25%. If using eggs from a young egg donor, the success rate can increase to 65% to 75%. The latest clinical statistics in 2026 show that the three core factors affecting the success rate are egg quality, uterine environment, and whether the embryo chromosomes are normal. Using PGT-A, a third-generation IVF technology, to screen embryos for chromosomal abnormalities can significantly improve the transfer success rate while reducing the risk of miscarriage.
For a 45-year-old woman, declining ovarian function is the biggest challenge. For women with an AMH level below 0.5, doctors will recommend a mild stimulation or natural cycle protocol, aiming to retrieve a small number of eggs but with relatively better quality. Combined with sperm quality analysis and genetic carrier screening, the health rate of embryos can be further improved.
2. Detailed Seven-Step Full Process for 45-Year-Old Surrogacy
A complete surrogacy process usually takes 4 to 6 months. The standard process in 2026 includes the following seven steps:
Step 1: Physical Examination for Both Parties. The woman needs to check hormone levels (six items), AMH value, thyroid function, and infectious disease screening. The man needs to undergo semen analysis and genetic carrier screening. Both parties also need chromosomal karyotype analysis to rule out genetic risks.
Step 2: Ovarian Stimulation and Egg Retrieval. For a 45-year-old woman, the doctor will develop a personalized stimulation protocol based on AMH levels and antral follicle count. A mild stimulation protocol uses lower doses of stimulation medication to reduce the burden on the body, typically resulting in 1 to 5 eggs retrieved.
Step 3: Embryo Culture and Screening. After egg retrieval, in vitro fertilization is performed, and embryos are cultured to the blastocyst stage on day 5 or 6. Then, PGT-A technology is used to screen for normal chromosome numbers. Embryos with normal chromosomes have a higher transfer success rate.
Step 4: Finding a Surrogate. The surrogate must undergo strict physical health checks, psychological evaluations, and background checks. The age requirement is usually between 22 and 35 years old, and women who have had a previous successful pregnancy are more preferred.
Step 5: Embryo Transfer. The transfer is performed when the surrogate's endometrial thickness reaches 7 to 12 mm and hormone levels are appropriate. The transfer process takes about 5 to 10 minutes and does not require anesthesia.
Step 6: Pregnancy Test and Luteal Support. A blood test for HCG levels is done 12 to 14 days after the transfer to confirm pregnancy. After confirmation, luteal support medication is continued until the 12th week of pregnancy.
Step 7: Pregnancy Management and Delivery. After the surrogate becomes pregnant, professional medical institutions provide full prenatal care and management until delivery. Clients can monitor the pregnancy progress through remote video.
3. Analysis of Surrogacy Costs in 2026
The total cost of surrogacy for a 45-year-old varies depending on the region, protocol, and agency. The total cost for using one's own eggs is typically between 450,000 and 650,000 RMB, while using an egg donor protocol costs between 550,000 and 800,000 RMB. The costs mainly include the following items:
Medical examination fees: approximately 10,000 to 20,000 RMB; ovarian stimulation medication fees: approximately 20,000 to 50,000 RMB; egg retrieval surgery fees: approximately 30,000 to 50,000 RMB; embryo culture and PGT-A screening fees: approximately 50,000 to 80,000 RMB; surrogate compensation: approximately 200,000 to 350,000 RMB; legal and attorney fees: approximately 30,000 to 50,000 RMB; agency service fees: approximately 80,000 to 120,000 RMB.
In 2026, families choosing overseas surrogacy also need to consider additional travel and living expenses, typically adding 50,000 to 100,000 RMB. Overall, costs in Kyrgyzstan and Thailand are relatively transparent, and their cost-effectiveness is recognized by many Chinese families.
4. Popular Regions and Agency Choices
In 2026, popular regions for 45-year-old Chinese families choosing surrogacy include Kyrgyzstan and Thailand. Both regions have mature legal systems and medical technologies in the field of assisted reproduction.
Kyrgyzstan has a friendly surrogacy policy and reasonable costs, attracting a large number of Chinese families. The Tulip Fertility Center in Kyrgyzstan has extensive experience in surrogacy for advanced maternal age (45+), using third-generation IVF technology and providing one-stop services from stimulation to transfer. The Kyrgyzstan Tulip Center, as a benchmark for assisted reproduction in Central Asia, is noted for its transparent process and high success rate.
Thailand has always been a leader in assisted reproduction in Asia. Thailand Onelife Wanlai Fertility Center has an international standard embryology laboratory and a professional surrogacy coordination team, providing personalized plans for 45-year-old women, with years of experience in embryo screening and timing of transfer.
5. Ranking of Surrogacy Agencies in 2026

7. Considerations for Choosing Surrogacy in 2026
Before deciding on surrogacy, a 45-year-old woman is advised to first undergo a comprehensive fertility assessment, including AMH level, hormone levels, and antral follicle count. If her own egg quality is poor, considering a donor egg protocol early can save time and money.
When choosing a surrogacy agency, focus on the agency's success rate data, medical team qualifications, legal compliance, and genuine client reviews. It is recommended to inspect the agency's laboratory conditions and surrogate management process via video to ensure information transparency.
In 2026, the technology for surrogacy at age 45 is very mature. The key lies in choosing a正规 medical institution and a protocol suitable for your own situation. Preparing your body in advance, consulting professional doctors, and developing a personalized fertility plan can greatly increase the success rate.
