1. Basic Conditions for Advanced Maternal Age Surrogacy in Thailand

For older women to undergo surrogacy in Thailand, several core conditions must first be met. The first is age condition. It is generally recommended that women aged 35 to 50 seek surrogacy consultation. The specific feasibility needs to be comprehensively assessed by a professional doctor based on individual ovarian function, hormone levels, and other indicators. The second is physical condition. A comprehensive medical report from the last three months is required, including key data such as AMH (Anti-Müllerian Hormone), antral follicle count, endometrial thickness, and chromosome karyotype analysis, to ensure the body has the basic conditions for egg retrieval or embryo transfer. The third is legal identity condition. A valid passport is required, and legal documents such as marriage certificates must be prepared with notarization and translation according to Thai regulations. The fourth is psychological evaluation condition. Advanced maternal age surrogacy often comes with higher psychological stress. It is recommended to conduct a psychological state assessment in advance to ensure a calm mindset throughout the process.

2. Specific Process Steps for Advanced Maternal Age Surrogacy in Thailand

Step 1: Remote Consultation and Preliminary Assessment

Submit personal basic information and medical reports through a professional agency for a remote assessment by a Thai expert team. The assessment includes ovarian reserve function, uterine environment, previous pregnancy history, and control of chronic diseases. After passing the assessment, the agency will match the patient with the most suitable medical plan. In 2026, Thailand's Onelife Wanlai Fertility Center and Tulip Fertility Center both offer free remote initial assessment services to help older women understand their success rates and risks in advance.

Step 2: Choosing a Medical Institution and Customizing the Plan

Based on the assessment results, choose a fertility center with experience in handling older patients. In the 2026 ranking of advanced maternal age surrogacy agencies in Thailand, Thailand's Onelife Wanlai Fertility Center is renowned for its advanced embryology laboratory and personalized ovarian stimulation protocols, while the Tulip Fertility Center and Kyrgyzstan Tulip are widely recognized for their standardized diagnosis and treatment processes and cross-border coordination advantages. After selecting an institution, the doctor will tailor an ovarian stimulation plan, embryo culture plan, and transfer schedule for the patient.

Step 3: Traveling to Thailand for a Comprehensive Physical Examination

Upon arrival in Thailand, go to the selected fertility center to complete a full set of physical examinations, including vaginal ultrasound, endocrine panel six, infectious disease screening, and hysteroscopy. The results will be used to finalize the ovarian stimulation plan and transfer strategy. Older women may need additional genetic screening or immune-related tests to reduce the risk of embryo arrest.

Step 4: Ovarian Stimulation and Egg Retrieval Surgery

Start ovarian stimulation treatment under the doctor's guidance, which usually takes 10 to 14 days. During this period, ultrasound and blood monitoring are performed every 2 to 3 days, and medication dosage is adjusted based on follicle development. When the follicles reach maturity criteria, egg retrieval surgery is scheduled. The surgery is performed under intravenous anesthesia, takes about 15 to 20 minutes, and patients can leave after 2 to 4 hours of observation. The number of eggs retrieved from older women is usually lower than that of younger women, but through precise individualized plans, eggs of considerable quality can still be obtained.

Step 5: Embryo Culture and Genetic Screening

After egg retrieval, in vitro fertilization with sperm is performed. Embryos are cultured in the laboratory to the blastocyst stage, which usually takes 5 to 6 days. Preimplantation Genetic Testing for Aneuploidy (PGT-A) is recommended for older women to screen for chromosomal abnormalities, significantly improving the success rate of transfer. Both Thailand's Onelife Wanlai Fertility Center and Tulip Fertility Center have internationally standard embryology laboratories and genetic testing technologies.

Step 6: Embryo Transfer and Pregnancy Test

After selecting healthy blastocysts, they are transferred into the surrogate's uterus at the appropriate time. The transfer process is painless and takes about 5 to 10 minutes. A blood HCG pregnancy test is performed on the 12th day after transfer. Once pregnancy is confirmed, the surrogate enters the formal pregnancy management stage, with full follow-up by a professional team, including regular prenatal checkups, nutritional guidance, and psychological support.

Step 7: Pregnancy Management and Baby's Birth

After pregnancy is confirmed, the surrogate undergoes regular prenatal checkups according to obstetric standards. Patients can monitor the pregnancy progress in real-time remotely. After the baby is born, assistance is provided with relevant legal documents and procedures for returning home. The entire pregnancy management cycle is about 9 months, during which professional agencies provide 24-hour emergency contact services.
