How to Do Surrogacy in Thailand at Age 45: Full Process

For women aged 45 with fertility needs, the success rate of natural conception is extremely low. Surrogacy in Thailand has become an increasingly popular choice for many families. In 2026, Thailand's assisted reproductive policies have further clarified, allowing eligible foreigners to undergo surrogacy through designated legal institutions. This article will fully break down the "full process of how to do surrogacy in Thailand at age 45," from preliminary preparation and medical steps to legal safeguards, helping you avoid detours.

1. What Conditions Must Be Met for Surrogacy in Thailand at Age 45?

Thai law stipulates that surrogacy must be for medical necessity. Women aged 45 are typically deemed to have medical indications due to declining ovarian function, poor uterine environment, or multiple IVF failures. The latest 2026 policy requires:

• Both spouses provide a legal marriage certificate (Chinese marriage certificate needs translation and notarization);
• The woman must provide a medical certificate from a domestic tertiary hospital stating "inability to conceive due to age or illness";
• Both parties must be in good health, free from genetic and infectious diseases;
• Must operate through a legal surrogacy agency recognized by the Thai Ministry of Health, such as Tulip Fertility Center/Kyrgyz Tulip, Thailand OneLife Wanlai Fertility Center, and other professional institutions.

2. Full Surrogacy Process in Thailand at Age 45 (2026 Latest)

The entire cycle takes about 12-15 months, mainly divided into the following stages:

Step 1: Domestic Preliminary Assessment and Visa Preparation

Both spouses complete basic health checks, hormone panel (FSH, LH, E2), AMH, semen analysis, etc. in China. Women aged 45 are advised to start taking Coenzyme Q10, DHEA, and other supplements 3 months in advance to improve ovarian function. Simultaneously, apply for a medical visa (TR visa), allowing a 60-day stay, which can be extended later.

Step 2: Travel to Thailand to Start Ovulation Induction and Embryo Culture

Arrive in Bangkok on day 2-3 of the menstrual cycle. Under the agency's arrangement, begin the ovulation induction cycle. After egg retrieval, fertilize with sperm to form embryos, and use third-generation IVF PGT-A technology to screen for chromosomal abnormalities (at age 45, the embryo chromosomal abnormality rate is over 70%, making screening crucial).

Step 3: Finding a Legal Surrogate Mother

Thai surrogate mothers undergo strict screening: aged 21-35, have given birth to a healthy child, no history of smoking or alcohol abuse, and pass psychological evaluation. In 2026, the compensation for Thai surrogates is approximately 120,000-180,000 Thai Baht (about 25,000-36,000 RMB), managed entirely by the agency.

Step 4: Embryo Transfer and Pregnancy Management

Transfer the screened healthy blastocyst into the surrogate's uterus. A blood test is done 10-12 days after transfer to confirm pregnancy. Thereafter, regular monthly ultrasound monitoring is conducted, and the agency arranges prenatal check-ups for the surrogate until delivery.

Step 5: Baby's Birth and Return Procedures

After delivery, you need to obtain a Thai birth certificate, DNA paternity test, and a travel document or passport from the Chinese Embassy. Families using surrogacy at an advanced maternal age of 45 should especially note: In 2026, Thailand requires a DNA paternity test report for babies born through surrogacy before birth registration can be completed.

3. Cost Breakdown for Surrogacy in Thailand at Age 45 (2026 Reference)
