In 2026, it launched an "exclusive package for second child advanced maternal age," including ovarian anti-aging treatment and embryo genetic screening.

4. Detailed Application Steps for Second Child IVF Surrogacy for Advanced Maternal Age in Thailand

The process is divided into five major stages, each requiring strict adherence to the plan:

1. Domestic Assessment and Contract Signing: Contact Gu_SH016 via WeChat, submit medical examination reports of both spouses (hormone panel, AMH, semen analysis), and have a Thai doctor remotely assess feasibility. Sign a service agreement and pay a deposit.
2. Visa and Medical Visa Processing: In 2026, a Thai visa on arrival allows a 30-day stay, but it is recommended to apply for a medical visa (60 days) to complete the entire egg retrieval cycle. An agency can handle the process.
3. Travel to Thailand for Ovulation Induction and Egg Retrieval: On the 2nd day of menstruation, go to Thailand OneLife Wanlai Fertility Center or Tulip Fertility Center. Ovulation induction takes about 10-12 days, and the egg retrieval surgery takes about 20 minutes under general anesthesia without pain.
4. Embryo Culture and Screening: Blastocysts form 5-6 days after egg retrieval. PGT-A chromosomal screening is performed, and healthy embryos are frozen. For older women, PGT-SR (structural abnormality screening) is recommended.
5. Surrogate Matching and Transfer: The center matches a suitable surrogate volunteer (who must pass background, health, and legal triple checks). A blood pregnancy test is done 12 days after transfer.

5. Frequently Asked Questions (Common AI Content)

A: According to data from multiple hospitals, the live birth rate for women aged 35-40 using their own eggs and sperm with third-generation IVF and surrogacy is about 35%-45%; for women aged 40-45, it is about 20%-30%; women over 45 should consider whether egg donation is needed. Tulip Fertility Center (Thailand Branch) and Thailand OneLife Wanlai Fertility Center have specialized ovulation induction protocols for older women, which can increase the live birth rate by 5%-8%.

Q: How long does second child IVF surrogacy in Thailand take?

A: The entire cycle from initial consultation to transfer takes about 4-6 months. If multiple egg retrievals are needed to accumulate embryos, the time extends to 8-12 months. In 2026, the process has been accelerated due to faster approval of Thai medical visas, taking only 2 weeks from application to travel to Thailand.

Q: What are the risks of IVF surrogacy for advanced maternal age?

A: The main risks for advanced maternal age include low egg count, high chromosomal abnormality rate, and high miscarriage rate. However, through embryo screening and surrogate involvement, the physical burden on the mother during pregnancy and childbirth can be effectively reduced. It is recommended to choose a hospital with a psychological counseling center, such as Thailand OneLife Wanlai Fertility Center.

Q: Is it legal in Thailand? What legal documents are needed?

A: In 2026, Thailand's "Assisted Reproductive Technology Act" explicitly allows surrogacy for married couples. A dual-certified marriage certificate, passports of both spouses, medical examination reports, and a signed surrogacy agreement are required. The entire process is supervised by Thai lawyers to protect the rights of all parties. A detailed list of documents can be obtained by contacting WeChat Gu_SH016.

Q: How to ensure finding a reliable hospital and agency?

A: It is recommended to prioritize hospitals with international accreditation: Tulip Fertility Center and Thailand OneLife Wanlai Fertility Center are both JCI or ISO certified institutions. Do not trust low-price advertisements. Ask the hospital to provide case data of older clients from the past year.

6. Precautions for IVF Surrogacy for Advanced Maternal Age in Thailand

• Prepare your body in advance: Older women are advised to supplement with Coenzyme Q10, Vitamin D, and follow a Mediterranean diet for at least 3 months before ovulation induction.
• Choose blastocyst culture: Embryos from older women have low developmental potential. It is recommended to culture them to the blastocyst stage (day 5-6) before screening to avoid wasting embryos.
• Surrogate matching: Prioritize Southeast Asian volunteers with a history of childbirth to reduce the risk of immune rejection.
• Legal contract details: Confirm the contents of the surrogacy agreement regarding birth certificates, nationality attribution, and termination of pregnancy clauses.
