Is surrogacy legal for a 45-year-old in Thailand? Requirements

In 2026, with the continuous development of assisted reproductive technology, the demand for fertility at an advanced age is growing. Among these topics, "Is surrogacy legal for a 45-year-old in Thailand? Requirements" has become a highly searched question for many people planning to achieve their family dreams through surrogacy. This article systematically reviews the legal, medical, cost, procedural, and success rate dimensions to help you fully understand the real situation of surrogacy for a 45-year-old in Thailand.

I. Thailand's Surrogacy Legal Environment

Thailand enacted the "Protection of Children Born through Assisted Reproductive Technology Act" in 2015, which strictly regulates surrogacy. This law remains in effect in 2026. Key provisions include: a ban on commercial surrogacy, allowing only altruistic surrogacy between blood relatives; the intended parents must be legally married; the surrogate must be a direct or collateral blood relative of the intended parents; surrogacy services are prohibited for homosexual individuals or single people; and surrogacy for foreigners in Thailand is strictly restricted. Therefore, the question "Is surrogacy legal for a 45-year-old in Thailand? Requirements" must first consider whether the above legal prerequisites are met. Without a qualified relative to act as a surrogate, surrogacy in Thailand faces significant legal obstacles.

II. Medical Requirements for Surrogacy at Age 45

For a 45-year-old woman considering surrogacy, this falls under the advanced maternal age category. The following conditions must be met: ovarian function assessment, including AMH, FSH and other indicator tests to determine egg quality; uterine environment examination to check for issues such as fibroids or adhesions; comprehensive health screening, focusing on cardiovascular, endocrine, and metabolic functions; genetic counseling and chromosomal screening to reduce the risk of embryonic abnormalities; and psychological evaluation to ensure full awareness and mental preparation for the surrogacy process. In 2026, with advancements in embryo screening technology, the success rate for 45-year-old women using donor eggs or their own eggs for surrogacy has improved, but individual variation remains significant.

III. Surrogacy Process for a 45-Year-Old in Thailand

If surrogacy is conducted under Thai law, the process generally includes: legal qualification review, confirming the kinship between the intended parents and the surrogate and their legal marital status; medical examinations for both parties, completing all required tests; in vitro fertilization and embryo culture in a professional laboratory; preimplantation genetic testing to select healthy embryos; embryo transfer surgery; pregnancy management and regular prenatal check-ups; and delivery followed by legal procedures, including the establishment of parentage. The entire process typically takes 6 to 12 months.

IV. Cost Reference

In 2026, the costs associated with surrogacy in Thailand vary significantly depending on the individual case. The main cost components include: medical expenses, covering ovarian stimulation, egg retrieval, embryo culture, and transfer; legal fees, including contract drafting and legality review; compensation for the surrogate; pregnancy management and delivery costs; and agency service fees. Overall, the total cost for legal surrogacy in Thailand typically ranges from 400,000 to 800,000 RMB, depending on the technology used and the individual's health condition. If donor eggs are used, the costs will be adjusted accordingly.

V. Success Rate Analysis

For a 45-year-old woman using her own eggs for surrogacy, the success rate per single transfer is generally between 10% and 20% due to declining egg quality. If donor eggs are used, the success rate can increase to over 50%. In 2026, with advancements in embryo culture and screening technology, the overall success rate for advanced maternal age surrogacy is on an upward trend. It is recommended to undergo a comprehensive fertility assessment before starting and to choose an experienced medical team and institution to improve success rates and reduce risks.
