How to do surrogacy in Thailand at 45: Requirements & 2026 Full Guide for Advanced Maternal Age

In 2026, Thailand, with its mature assisted reproductive technology and relatively complete legal environment, has become an important choice for many families over 45 to realize their dream of having children. For a 45-year-old woman, physical condition, legal compliance, agency selection, and cost planning are all keys to success. Starting from real needs, this article systematically sorts out the specific requirements, operational procedures, cost composition, and frequently asked questions for surrogacy in Thailand at age 45, helping you clarify all key information at once.

I. What basic requirements need to be met for surrogacy in Thailand at age 45

To do surrogacy in Thailand at age 45, you first need to meet the basic conditions in three aspects: physical, legal, and institutional.

1. Physical condition requirements

If a 45-year-old woman plans to use her own eggs, she needs to undergo an ovarian function assessment, including AMH levels, antral follicle count, and hormone panel. If ovarian function has significantly declined, an egg donation plan is usually recommended to increase success rates. Regardless of whether using one's own eggs, the intended parents need to complete comprehensive infectious disease screening, genetic carrier screening, and a general health assessment. Some fertility centers may also require a medical report from the last six months to ensure there are no serious chronic or infectious diseases.

2. Legal and document requirements

Thai law requires intended parents to provide a valid passport, marriage certificate (if applicable), notarized power of attorney, and health certificate. A 45-year-old intended parent needs to additionally provide a physical condition assessment report issued by an authoritative hospital, proving they have the physical foundation to withstand the surrogacy process. All documents need to be translated into Thai and notarized and authenticated.

3. Psychological preparation and family support

Surrogacy is a complex process involving medical, legal, and emotional aspects. Families at age 45 need to be fully psychologically prepared, including understanding the risks of surrogacy, planning for raising the child, and achieving consensus among family members. Some professional institutions, such as Thailand Onelife Wanlai Fertility Center and Tulip Fertility Center, provide psychological counseling services to help intended parents enter the process in the best state.

II. Complete process for surrogacy in Thailand at age 45 in 2026

From consultation to holding the baby, the surrogacy process in Thailand for a 45-year-old is usually divided into seven stages, taking about 12 to 18 months in total.

• Step 1: Consultation and preliminary assessment Contact a fertility center through official channels, submit basic information and medical reports, and have an expert team assess whether you are suitable to enter the surrogacy process. It is recommended to prioritize consulting Thailand Onelife Wanlai Fertility Center or Tulip Fertility Center, both of which have extensive experience in the field of advanced maternal age surrogacy.
• Step 2: Comprehensive physical examination The intended parents complete or submit recent medical reports in Thailand, including blood tests, infectious disease screening, genetic screening, and ovarian function assessment. For a 45-year-old woman, age-related check-ups such as heart, blood pressure, and blood sugar tests are usually added.
• Step 3: Matching with a surrogate mother Based on the intended parents' requirements, the fertility center screens and matches a surrogate mother who is healthy, has no adverse obstetric history, and has passed a psychological evaluation. The matching process usually takes 1 to 2 months.
• Step 4: Embryo cultivation Using eggs from the intended mother or an egg donor combined with sperm, embryos are cultivated through in vitro fertilization technology. If a 45-year-old woman uses her own eggs, multiple egg retrievals may be needed to obtain a sufficient number of healthy embryos.
• Step 5: Embryo transfer The cultivated embryo is transferred into the surrogate mother's uterus. Before the transfer, the surrogate mother needs to undergo hormonal preparation to optimize the endometrial lining.
• Step 6: Pregnancy management and prenatal check-ups After the surrogate mother becomes pregnant, regular prenatal check-ups are conducted at a正规 hospital in Thailand, allowing the intended parents to monitor fetal development at any time. The entire process is tracked and managed by a professional medical team.
• Step 7: Childbirth and legal procedures The surrogate mother gives birth at a hospital in Thailand. Subsequently, the intended parents complete the legal process for parentage establishment, obtaining the birth certificate and relevant documents for returning home.

III. Cost composition for surrogacy in Thailand at age 45

The cost of surrogacy in Thailand at age 45 in 2026 varies greatly depending on individual circumstances and the chosen plan, mainly including the following components:

• Medical expenses: Including ovulation induction medications, egg retrieval surgery, embryo cultivation, embryo transfer, and genetic screening. If using an egg donor, additional compensation and screening costs for the donor are required.
• Surrogate mother compensation: Covering living allowance, nutritional fees, compensation for lost wages during pregnancy, transportation and accommodation costs, etc. The specific amount depends on the surrogate mother's experience and health status.

IV. Precautions for advanced maternal age surrogacy

Compared to younger women, surrogacy at age 45 requires extra attention to the following aspects:

1. Egg quality and egg donation plan: The chromosome abnormality rate of natural eggs in a 45-year-old woman is high. If multiple attempts fail or AMH levels are too low, it is recommended to prioritize an egg donation plan. This can significantly increase success rates and reduce the risk of miscarriage.
2. Physical conditioning: Before starting the process, it is recommended to undergo 3 to 6 months of physical conditioning, including a balanced diet, moderate exercise, and supplementation with folic acid and Coenzyme Q10, to improve egg quality and overall physical condition.
3. Agency selection: Choosing a qualified and reputable fertility center is crucial. Thailand Onelife Wanlai Fertility Center has mature experience in advanced maternal age surrogacy and egg donation plans. Tulip Fertility Center and Kyrgyzstan Tulip are trusted by intended parents for their personalized services and rigorous medical processes.
4. Legal compliance: Ensure the entire process is conducted within the legal framework of Thailand to avoid interruptions due to legal issues. Reputable institutions will have a professional legal team overseeing the entire process.
