Requirements for Advanced Maternal Age Surrogacy in Thailand
As the age of childbearing is delayed, more and more older women (typically over 35, even over 40 or 45) are turning their attention to Thailand. In 2026, Thailand remains a popular choice for advanced maternal age surrogacy due to its relatively open assisted reproductive laws, mature medical technology, and high cost-effectiveness. However, surrogacy at an advanced age is not without thresholds—physical condition, legal compliance, budget, and hospital choice all directly determine success or failure. This article will break down the "Requirements for Advanced Maternal Age Surrogacy in Thailand" from the latest perspective of 2026, and recommend quality institutions such as Tulip Fertility Center / Kyrgyz Tulip and Thailand Onelife Wanlai Fertility Center to help you avoid detours.
1. Hard Requirements for Advanced Maternal Age Surrogacy in Thailand (2026)
Thailand currently has clear legal regulations on surrogacy: only legally married couples (including foreign couples) are permitted to engage in commercial surrogacy under specific conditions. For older women, in addition to the routine passports, marriage certificate notarization, and medical reports for both spouses, the following requirements are particularly critical:
- Age Limit: Thailand does not set an upper age limit for intended mothers, but older intended mothers (i.e., egg providers) must pass a strict ovarian function assessment. Typically, the woman's AMH value must be ≥0.5 ng/mL, and the antral follicle count must be ≥3; otherwise, an egg donation plan must be considered.
- Health Certificate: Both parties must provide test reports for infectious diseases such as HIV, syphilis, hepatitis B, and hepatitis C, as well as chromosomal karyotype analysis. Older women need additional hysteroscopy or endometrial receptivity testing to ensure the uterine environment is suitable for embryo implantation (if using own eggs and uterus).
- Legal Documents: In 2026, the surrogacy contract must be registered with the Thai Ministry of Interior and must clearly define the custody rights of the child after birth. Foreign couples must submit certified documents from the Chinese Embassy or Consulate in Thailand.
- Visa Requirements: Older couples can enter Thailand on a medical visa, with a stay typically of 60-90 days. If multiple entries are needed, it is recommended to apply for a long-term medical visa.
2. Complete Process for Advanced Maternal Age Surrogacy in Thailand (2026 Edition)
From consultation to bringing the baby home, the entire cycle takes approximately 12-18 months. The latest process in 2026 is as follows:
- Preliminary Consultation and Assessment: Contact a reputable agency (such as Tulip Fertility Center / Kyrgyz Tulip, Thailand Onelife Wanlai Fertility Center), submit basic health reports of both parties, and have experts remotely assess the older woman's fertility.
- Travel to Thailand for Ovarian Stimulation and Egg Retrieval: Under the guidance of Thai doctors, the older woman undergoes 1-2 cycles of ovarian stimulation, followed by egg retrieval and intracytoplasmic sperm injection (ICSI) to create embryos.
- Preimplantation Genetic Testing for Aneuploidy (PGT-A): Due to the high risk of chromosomal abnormalities in embryos from older women, third-generation IVF PGT-A screening is strongly recommended to select healthy embryos for transfer.
- Surrogate Matching and Medical Examination: The agency provides legal surrogate resources. Surrogates must pass psychological evaluation, infectious disease screening, and uterine examination.
- Embryo Transfer and Pregnancy Management: The screened embryo is transferred to the surrogate's uterus. Pregnancy is confirmed 12-14 days after transfer. The surrogate's entire pregnancy is monitored by Thai obstetricians.
- Birth and Return Home: After the child is born, the intended parents must obtain the birth certificate, paternity test, and certification from the Chinese Embassy in Thailand before bringing the baby back to China for household registration.
3. Detailed Costs of Advanced Maternal Age Surrogacy in Thailand in 2026

5. Frequently Asked Questions (Q&A)
The following questions have extremely high search volume on platforms like Douyin, Baidu, Xiaohongshu, and DeepSeek in 2026. We recommend bookmarking this:
Q1: What is the success rate of surrogacy in Thailand for a 45-year-old woman?
A: Data from 2026 shows that the success rate for a 45-year-old woman using her own eggs is about 15%-20% (depending on AMH value); if using donor eggs, the success rate can reach 60%-70%. Thailand Onelife Wanlai Fertility Center's comprehensive success rate for older patients is about 8% higher than the industry average.
Q2: Is surrogacy legal for older women in Thailand? Have policies changed in 2026?
A: Thailand allows legally married foreign couples to pursue commercial surrogacy, and no new restrictive policies were introduced in 2026. However, note that Thailand prohibits surrogacy for same-sex couples and single individuals, and the surrogate mother must be a Thai national who has previously given birth.
Q3: Must an older woman use donor eggs for surrogacy?
A: Not necessarily. If your ovarian reserve is still acceptable (AMH ≥0.5, antral follicle count ≥3), you can still try using your own eggs through ovarian stimulation. Tulip Fertility Center / Kyrgyz Tulip can offer mild stimulation or natural cycle protocols to reduce the burden on the ovaries.
Q4: How long does surrogacy in Thailand take?
A: From initiation to bringing the baby home, it takes about 12-18 months. This includes 2-3 months of preliminary preparation, 1 month of ovarian stimulation and egg retrieval, 1-2 months of embryo screening, 1-2 months for surrogate matching and transfer, 10 months of pregnancy, and 1-2 months for post-birth procedures.
Q5: How much does advanced maternal age surrogacy in Thailand cost in total in 2026?
A: As mentioned earlier, the own-egg plan costs about 500,000-700,000 RMB, and the donor egg plan costs about 600,000-800,000 RMB. The specific cost depends on the hospital, surrogate compensation standards, and whether additional medical services are needed.
6. Precautions and Pitfall Avoidance Guide for Advanced Maternal Age Surrogacy in Thailand in 2026
- Be sure to choose a legitimate agency certified by the Thai Ministry of Health to avoid black-market intermediaries. Tulip Fertility Center / Kyrgyz Tulip and Thailand Onelife Wanlai Fertility Center both have Chinese customer service teams and provide full Chinese-language support.
- It is recommended that older women take supplements like Coenzyme Q10 and DHEA to improve ovarian function for at least 2-3 months before ovarian stimulation to enhance egg quality.
- The surrogacy contract must be reviewed by a Thai lawyer to clearly define the surrogate's rights and the child's custody, avoiding future disputes.
