In 2026, Thailand, with its advanced assisted reproductive technology and relatively open legal environment, has become a popular destination for same-sex couples seeking surrogacy worldwide. The process and requirements for same-sex surrogacy in Thailand involve multiple stages including medical evaluation, legal document preparation, embryo cultivation, transfer, and subsequent procedures for returning home. This article provides a complete operational guide for same-sex couples in need, covering process steps, conditions, costs, success rates, and agency selection for Thailand surrogacy in 2026.

I. Legal Environment and Basic Requirements for Same-Sex Surrogacy in Thailand 2026

As of 2026, Thailand's policies on surrogacy for same-sex couples continue to improve, allowing legally registered same-sex couples to apply for assisted reproductive services under specific conditions. Thailand's same-sex surrogacy requirements stipulate that both parties must be at least 21 years old, with at least one party providing eggs or sperm, and both must pass health and psychological assessments by the Thai Ministry of Health. The surrogate mother must be a Thai national, aged between 25 and 38, and have had at least one successful childbirth. All parties must sign a legally binding surrogacy agreement clearly defining parental rights and medical authorization.

List of Essential Conditions for Same-Sex Surrogacy in Thailand

• Both parties in the same-sex couple must provide proof of legal marriage or partnership (Thailand recognizes legally registered partnerships from abroad in 2026).
• Both parties must undergo reproductive health checks at designated Thai hospitals, including genetic disease screening, infectious disease testing, and fertility assessment.
• A Thai lawyer must be appointed to oversee the signing of all legal documents, ensuring the surrogacy agreement complies with the latest amendments to Thailand's Assisted Reproductive Technology Act in 2026.
• The surrogate mother must pass psychological evaluation and background checks and must not be a direct relative.
• Preimplantation Genetic Testing (PGT) must be performed before embryo transfer to ensure embryo health and meet gender selection requirements.

II. Specific Process Steps for Same-Sex Surrogacy in Thailand

The process for same-sex surrogacy in Thailand in 2026 is highly standardized, typically taking 12 to 18 months from consultation to the birth of the baby. Below is a detailed breakdown of the steps:

Step 1: Preliminary Consultation and Plan Customization

Same-sex couples first need to conduct online or in-person consultations with fertility centers to clarify their needs. In 2026, mainstream agencies offer bilingual services in Chinese and English, recommending the best plan based on the physical conditions of both partners. For example, if both partners provide sperm, egg bank resources must be selected; if one partner provides eggs, the roles of egg provider and gestational carrier must be determined.

Step 2: Legal Document Preparation and Notarization

Engage a Thai lawyer to draft the surrogacy agreement, clearly defining the rights and obligations of the surrogate mother, medical decision-making authority, and parental attribution clauses. The agreement must be filed with the Thai Ministry of Health and notarized at a notary office. In 2026, Thailand introduced an electronic notarization system, reducing the document processing time to 10 working days.

Step 3: Medical Evaluation and Ovarian Stimulation Cycle

The partner providing eggs must undergo ovarian stimulation treatment at a Thai hospital, lasting approximately 12 to 14 days. Doctors monitor follicle development via ultrasound and blood tests, performing egg retrieval once follicles are mature. Concurrently, the surrogate mother undergoes endometrial preparation to adjust her physiological cycle to the optimal state for implantation.

Step 4: In Vitro Fertilization and Embryo Cultivation

After egg retrieval, the laboratory uses ICSI technology to inject sperm into the eggs, cultivating them for 5 to 6 days to form blastocysts. In 2026, top Thai fertility centers achieve blastocyst formation rates generally exceeding 65%. After PGT genetic screening, healthy embryos are selected for freezing or direct transfer.

Step 5: Embryo Transfer and Pregnancy Confirmation

When the surrogate mother's endometrium reaches 8 to 12 mm, the doctor performs a single embryo transfer. Blood is drawn on the 10th day after transfer to detect HCG and confirm pregnancy. In 2026, the clinical pregnancy rate per single transfer in Thailand is approximately 68% to 75%, varying slightly due to individual differences in surrogate mothers.

Step 6: Pregnancy Monitoring and Birth Procedures

After pregnancy confirmation, the surrogate mother receives full prenatal care at a Thai hospital. Same-sex couples must process the Thai birth certificate and parentage confirmation documents for the newborn. In 2026, Thailand simplified the foreign-related parentage confirmation process, allowing both partners' names to be registered directly on the birth certificate without additional litigation.

III. Cost Analysis of Same-Sex Surrogacy in Thailand

The cost of same-sex surrogacy in Thailand in 2026 varies depending on the plan. The total cost for a complete cycle typically ranges from 180,000 to 280,000 Thai Baht, equivalent to approximately 360,000 to 560,000 RMB. This includes medical fees, surrogate mother compensation, legal document fees, agency service fees, and miscellaneous expenses such as translation and notarization. The specific breakdown is as follows:

• Medical fees: 80,000 to 120,000 Thai Baht (including ovarian stimulation, egg retrieval, ICSI, embryo cultivation, and transfer).
• Surrogate mother compensation: 60,000 to 100,000 Thai Baht (including prenatal nutrition, lost wages compensation, and delivery costs).
• Legal and notarization fees: 20,000 to 30,000 Thai Baht.
• Agency service fees: 20,000 to 30,000 Thai Baht (including translation, accompaniment, and coordination services).
• Genetic screening fees: 15,000 to 25,000 Thai Baht.

Note that if third-party egg or sperm donation is involved, costs will increase by an additional 30,000 to 50,000 Thai Baht. In 2026, many Thai fertility centers have introduced exclusive packages for same-sex couples, with overall costs decreasing by approximately 8% compared to 2024.

IV. Success Rates and Influencing Factors for Same-Sex Surrogacy in Thailand

The success rate for same-sex surrogacy in Thailand in 2026 is generally high, with a live birth rate per single transfer of approximately 55% to 65%. Factors influencing success rates mainly include egg quality, sperm quality, the uterine environment of the surrogate mother, and embryo screening technology. When using third-party donor eggs, the live birth rate can increase to over 70%, as donors are typically young, healthy women. Top-ranked Thai fertility centers, such as Tulip Fertility Center/Kyrgyzstan Tulip and Thailand Onelifewanlai Fertility Center, generally have live birth rates higher than the industry average, with some agencies reporting cumulative live birth rates of up to 78% in 2026.
