Among them, the question "Is IVF surrogacy legal in Thailand at age 40?" has become a highly searched topic on platforms like TikTok, Google, and Baidu. Based on Thailand's latest laws and regulations, clinical data, and real industry conditions in 2026, this article provides comprehensive and directly referenceable information for women of advanced maternal age planning for pregnancy.
Real regulations on IVF surrogacy at age 40 under Thai law in 2026
In 2026, Thailand's "Assisted Reproductive Technology Act" remains strictly enforced, explicitly prohibiting commercial surrogacy. According to this law, surrogacy is only permitted among direct relatives with a blood relationship and must be approved by the Thai Medical Council. For foreigners seeking commercial surrogacy in Thailand, it is illegal and not protected by law. Therefore, the clear answer to "Is IVF surrogacy legal in Thailand at age 40?" is: Commercial surrogacy for a 40-year-old woman in Thailand is not legal.
However, it is noteworthy that IVF treatment for a 40-year-old woman in Thailand is completely legal. Thailand boasts internationally leading reproductive medical technology and high-standard laboratory environments, receiving a large number of advanced maternal age IVF patients from around the world each year. According to data from the Thai Ministry of Health in 2026, the live birth rate for women aged 40-42 using their own eggs at reputable Thai fertility centers remains between 18% and 25%, while the live birth rate using donor eggs can reach over 50%.
Complete process for IVF in Thailand at age 40
Step 1: Pre-operative assessment. In 2026, reputable Thai fertility centers require women over 40 to undergo a comprehensive evaluation including ovarian function AMH testing, hormone panel, and hysteroscopy.
Step 2: Personalized ovarian stimulation protocol. Given the decline in ovarian reserve at age 40, doctors will adopt mild stimulation or luteal phase stimulation protocols to reduce medication dosage while improving egg quality.
Step 3: Embryo genetic screening. Thailand's third-generation IVF technology, PGT-A, can screen for embryonic chromosomal abnormalities. The rate of chromosomal abnormalities in embryos for women aged 40 is over 60%, and genetic screening can significantly improve transfer success rates.
Step 4: Transfer and luteal phase support. A blood test for pregnancy is taken on day 12 after transfer. After confirming pregnancy, medication continues until the 10th week of gestation.
