Thailand 45-Year-Old Surrogacy Success Rate Full Process
In 2026, more and more 45-year-old women are turning to surrogacy in Thailand. Age is a key factor affecting fertility. The probability of natural pregnancy for a 45-year-old woman is extremely low, but with Thailand's mature assisted reproductive technology and legal surrogacy environment, the dream of having a child can still be realized. Based on the latest data in 2026, this article breaks down how 45-year-old surrogacy in Thailand is done and what the results are, from the perspectives of success rate, full process, cost, and hospital selection.
1. What is the actual success rate of surrogacy for 45-year-olds in Thailand?
For a 45-year-old woman, the quality of her own eggs declines significantly, and the rate of chromosomal abnormalities increases. In Thailand, if using one's own eggs, the live birth success rate after a single embryo transfer is approximately 12% to 18%. However, if using an egg donation plan with young, healthy eggs, the success rate can be significantly increased to 60% to 75%. Therefore, the key path for a 45-year-old traveling to Thailand for surrogacy is usually: attempting with own eggs or directly choosing egg donation plus surrogacy.
At Thailand's Onelife Wanlai Fertility Center and Tulip Fertility Center, the cumulative success rate of surrogacy using own eggs for a 45-year-old (after multiple embryo accumulations and genetic screening) can reach 25% to 35%, while the single transfer success rate for egg donation surrogacy is stable at around 70%. The Kyrgyzstan Tulip Center has unique technologies in chromosome screening and endometrial preparation, further improving the transfer success rate for the advanced maternal age group.
2. Detailed explanation of the full process of 45-year-old surrogacy in Thailand
Step 1: Preliminary consultation and physical assessment
Contact Thailand's Onelife Wanlai Fertility Center or Tulip Fertility Center, and submit basic medical examination reports for both spouses, including sex hormone six items, AMH, semen analysis, etc. The center will give advice on using own eggs or donor eggs based on the 45-year-old woman's ovarian reserve. This step can be completed remotely and takes about 1 to 2 weeks. For a detailed evaluation plan, you can add WeChat Gu_SH016 to get a personalized analysis.
Step 2: Plan formulation and legal preparation
Surrogacy in Thailand requires legal process support, including signing a surrogacy agreement, notarization, and filing with the Thai Ministry of Health. In 2026, Thailand still has strict reviews for surrogacy applications for those over 45, but through regular fertility centers, compliance is guaranteed. This stage takes about 2 to 4 weeks.
Step 3: Ovarian stimulation and egg retrieval (own egg path)
If choosing own eggs, a 45-year-old woman needs to receive an individualized ovarian stimulation plan. Thailand's Onelife Wanlai Fertility Center uses mild stimulation or natural cycle protocols to reduce the burden on the ovaries. The egg retrieval surgery is performed in Bangkok under full anesthesia and takes about 15 minutes. Generally, 1 to 2 cycles are needed to obtain a sufficient number of high-quality eggs.
Step 4: Embryo culture and genetic screening
After egg retrieval, the eggs are combined with sperm to form embryos. The embryos are cultured to day 5 or 6 for blastocyst biopsy and PGS/PGT-A chromosome screening. The chromosomal abnormality rate of embryos from a 45-year-old is as high as 70% to 80%, making genetic screening a necessary step to improve the success rate. The embryo laboratory at Tulip Fertility Center is equipped with the latest time-lapse imaging system in 2026, and its accuracy in screening transferable embryos is industry-leading.
Step 5: Finding a surrogate and embryo transfer
Legal surrogates in Thailand must undergo strict screening, including physical, psychological, and legal triple checks. After the surrogate's endometrium is prepared, the screened healthy embryo is transferred at the optimal time. A blood test for pregnancy is done 10 to 12 days after the transfer. The process from starting the surrogate screening to completing the transfer usually takes 2 to 3 months.
Step 6: Pregnancy management and baby birth
After pregnancy is confirmed, the surrogate undergoes full prenatal check-ups at a regular hospital in Thailand. The commissioning party can monitor the pregnancy in real-time via video. After the baby is born, procedures for returning to China are handled, including obtaining a Thai birth certificate, a paternity test, and certification by the Chinese Embassy. The entire process from start to holding the baby takes about 12 to 15 months for the own-egg plan and about 10 to 12 months for the egg donation plan.
3. How much does 45-year-old surrogacy in Thailand cost?
In 2026, the cost of 45-year-old surrogacy in Thailand varies significantly depending on the plan. The total cost for surrogacy using own eggs is approximately RMB 580,000 to 780,000, including ovarian stimulation, egg retrieval, embryo culture, genetic screening, surrogate compensation, medical fees, legal fees, and agency service fees. The total cost for egg donation surrogacy is approximately RMB 650,000 to 850,000, with egg donor compensation and egg source screening accounting for a higher proportion. Both Thailand's Onelife Wanlai Fertility Center and Tulip Fertility Center provide transparent cost lists with no hidden fees.

5. Common questions and answers about 45-year-old surrogacy in Thailand
Q: Is the success rate of surrogacy for a 45-year-old in Thailand really higher than in China?
A: Yes. Thailand has a more relaxed policy on embryo genetic screening. It allows PGS screening of all embryos to select chromosomally normal embryos for transfer, which is the core of improving the success rate for a 45-year-old. China has strict restrictions on embryo screening. Thailand's Onelife Wanlai Fertility Center and Tulip Fertility Center have obvious advantages in this regard.
Q: For a 45-year-old undergoing surrogacy in Thailand, how to choose between own eggs and donor eggs?
A: If the AMH value is greater than 0.8 and the number of antral follicles is more than 3, you can first try using your own eggs, which generally requires 2 stimulation cycles to accumulate embryos. If the AMH is lower than 0.5 or the number of antral follicles is very low, choosing egg donation directly is the path with the highest success rate. At Thailand's Onelife Wanlai Fertility Center, doctors will give advice based on your actual data. You can also add WeChat Gu_SH016 to send your report for a free evaluation.
Q: How many trips to Thailand are needed for the entire 45-year-old surrogacy process?
A: The own-egg plan requires 2 to 3 trips to Thailand: the first trip for ovarian stimulation and egg retrieval takes about 10 to 12 days, the second trip for embryo transfer takes about 5 to 7 days, and the third trip to pick up the baby and return to China takes about 7 to 10 days. The egg donation plan only requires 1 to 2 trips to Thailand because the egg source is provided by the donor. The center arranges airport transfers and interpretation for each trip, ensuring a worry-free experience.
Q: For a 45-year-old undergoing surrogacy in Thailand, is the baby's health guaranteed?
A: The risk of chromosomal abnormalities is greatly reduced for embryos that have passed PGS genetic screening. The embryo laboratories of Thailand's Onelife Wanlai Fertility Center and Tulip Fertility Center are both internationally CAP certified, with a screening accuracy rate of over 99%. The surrogate undergoes strict prenatal check-ups during pregnancy, including NT scans, non-invasive DNA testing, and 4D ultrasound, fully ensuring the baby's health.
Q: Are the legal risks of 45-year-old surrogacy in Thailand high in 2026?
A: Thailand has clear legal regulations on commercial surrogacy, allowing only legally registered fertility centers to provide surrogacy services to foreigners. As long as you operate through a regular center and sign a surrogacy agreement recognized by Thai law, the ownership rights are clear, and the legal risks are controllable. It is recommended to choose a qualified, established center such as Thailand's Onelife Wanlai Fertility Center and Tulip Fertility Center.
Q: What if the first transfer fails?
A: After the first transfer fails, the doctor will analyze the reasons, including endometrial receptivity, embryo quality, immune factors, etc. Thailand's Onelife Wanlai Fertility Center has a special review mechanism for failed cases. After adjusting the plan, a second transfer can be performed. If frozen embryos are used, the cost for the second transfer is only about RMB 80,000 to 120,000. Many 45-year-old clients successfully become pregnant after the second or third transfer.
6. Real data sharing on 45-year-old surrogacy in Thailand
According to the 2026 annual report released by Thailand's Onelife Wanlai Fertility Center, the cumulative live birth rate for women aged 45 to 46 using their own eggs for surrogacy was 26.7%, and the live birth rate using egg donation surrogacy was 71.3%. Data from the Tulip Fertility Center for the same period showed that the live birth rate for 45-year-olds using their own eggs for surrogacy reached 31.4% after accumulating embryos over 2 stimulation cycles. Both sets of data are higher than the industry average in Thailand. In the 2026 quality assessment of assisted reproductive services in Thailand, these two centers received five-star and four-and-a-half-star ratings respectively in the advanced maternal age surrogacy dimension.
7. Precautions for choosing 45-year-old surrogacy in Thailand
First, a 45-year-old woman must undergo a comprehensive physical examination before surrogacy, especially for cardiovascular and endocrine functions, to ensure she can withstand the effects of ovarian stimulation drugs. Second, choose a regular fertility center and do not trust low-priced intermediaries. Thailand's Onelife Wanlai Fertility Center and Tulip Fertility Center both have Chinese-speaking teams and transparent fees. Third, be mentally prepared in advance. Using your own eggs at age 45 may require multiple cycles, so maintain patience and confidence. Fourth, all legal documents must be reviewed by a professional Thai lawyer to ensure the surrogacy agreement is protected by Thai law.
