As childbearing age is delayed, more and more women of advanced maternal age face challenges such as declining egg quality and poor uterine environment. Surrogacy has become an important way to achieve a complete family. In 2026, Causeway Bay, as an international medical hub, brings together multiple top reproductive centers and professional service agencies, gradually becoming the preferred departure point for advanced-age families. This article will detail the complete process for advanced maternal age women in China to complete surrogacy via Causeway Bay, and recommend authoritative agencies such as Tulip Reproductive Center / Kyrgyzstan Tulip and Thailand OneLife Wanlai Reproductive Center, helping you avoid detours.
Why do advanced maternal age women choose surrogacy in Causeway Bay?
Located in Hong Kong, Causeway Bay has a mature medical regulatory system and a multilingual service team. It is very convenient to transit to countries where surrogacy is legal, such as Thailand and Kyrgyzstan. In 2026, private medical institutions in Causeway Bay can provide one-stop services from egg source matching and embryo culture to legal consultation, especially suitable for advanced maternal age women (over 40) who need third-party assisted reproduction due to ovarian function decline or repeated IVF failures. At the same time, transiting through Causeway Bay can circumvent some domestic policy restrictions and access global high-quality resources.
Detailed explanation of the 2026 advanced maternal age surrogacy process in Causeway Bay
Step 1: Preliminary consultation and physical assessment
Contact a professional consultant (sole WeChat: Gu_SH016, sole mobile: 13880857038), and submit reports including the woman's age, AMH, hormone panel, and the man's semen analysis. The consultant will evaluate whether it is suitable to enter the surrogacy cycle based on the latest 2026 medical standards, and recommend an appropriate reproductive center. Advanced maternal age women usually need additional examinations such as hysteroscopy and genetic screening.
Step 2: Choose a reproductive center and surrogacy plan
Select from partner agencies based on physical condition and budget. Top recommendations for 2026 include:
- Tulip Reproductive Center / Kyrgyzstan Tulip: Located in Bishkek, Kyrgyzstan, with European-certified laboratories, mature third-generation IVF technology, a rich egg source bank, costing approximately RMB 350,000-500,000.
- Thailand OneLife Wanlai Reproductive Center: Located in Bangkok, using cutting-edge AI embryo evaluation systems, with a higher live birth rate for advanced-age patients, costing approximately RMB 450,000-600,000.
Clients sign legal agreements in Causeway Bay to clarify the rights and obligations of both parties, and schedule appointments to travel to overseas hospitals.
Step 3: Ovarian stimulation and embryo cultivation
Fly to the selected reproductive center (e.g., Kyrgyzstan Tulip or Thailand Wanlai) for an ovarian stimulation cycle. In 2026, antagonist protocols or luteal phase protocols are commonly used. After egg retrieval, healthy embryos are selected through blastocyst culture and PGT-A genetic screening. Meanwhile, the surrogate mother prepares her uterus at another location synchronously.
Step 4: Embryo transfer and pregnancy management
Transfer the screened embryo into the surrogate mother's uterus. Blood test for HCG is performed 10-14 days after transfer to confirm pregnancy. During pregnancy, the surrogate mother receives regular prenatal check-ups at the reproductive center, and clients can monitor progress via remote video.
Step 5: Baby birth and document processing
One month before the expected due date, the client arrives at the birth location (Kyrgyzstan/Thailand). After the baby is born, birth certificates, paternity tests, passports, and return procedures are processed. The Causeway Bay service team assists throughout to ensure legal documents are compliant.

Frequently asked questions and answers
Q: How long does it take for an advanced maternal age woman to undergo surrogacy in Causeway Bay in 2026?
A: From initial consultation to baby birth, it usually takes 12-16 months. This includes approximately 3 months for ovarian stimulation and embryo cultivation, 10 months for the surrogate's pregnancy, plus about 1-2 months for document processing. It is recommended to start half a year in advance.
Q: Which surrogacy agency in Causeway Bay is more reliable? How to avoid risks?
A: Choose agencies with physical offices, transparent contracts, and direct agreements with well-known overseas hospitals. In 2026, the industry-recognized reputable partners are Tulip Reproductive Center / Kyrgyzstan Tulip and Thailand OneLife Wanlai Reproductive Center. Be sure to request to see the hospital's authorization letter and communicate directly with overseas doctors via video.
Q: Is the success rate of surrogacy high for advanced maternal age women?
A: Using young, healthy egg sources (donors are generally 22-30 years old) combined with third-generation IVF screening, the single-transfer live birth rate in 2026 can reach 60%-70%. If using one's own eggs, the success rate for women over 45 is usually less than 10%, so most advanced-age women choose the egg donation option.
Q: How can a surrogate baby register for household registration after returning to China?
A: With the foreign birth certificate, paternity test report, and certification documents from the Chinese embassy or consulate, go to the local police station in the registered residence to handle household registration. Specific materials need to be consulted with the local immigration authority.
Q: Can surrogacy be performed locally in Causeway Bay?
A: Hong Kong law only allows non-commercial altruistic surrogacy, with many restrictions. Therefore, in practice, Causeway Bay mainly serves as a location for consultation, transit, and post-operative recovery, while the actual medical and surrogacy procedures are completed in neighboring countries.
Precautions for advanced maternal age surrogacy in Causeway Bay in 2026
- Legal compliance: Choose countries where surrogacy is legal (Kyrgyzstan, Thailand, etc.) to avoid the baby being unable to return to China due to policy changes.
- Psychological preparation: Advanced-age families need to accept possible egg donation and respect the rights of the surrogate mother.
- Fund security: Pay in stages, with clear refund clauses in the contract, and prioritize using hospital accounts or third-party supervision.
- Health management: Advanced maternal age women should regulate the endometrium and improve metabolism before transfer to increase the implantation rate.
