For women aged 35 and above, natural pregnancy becomes significantly more difficult. Hong Kong, with its advanced medical technology, relatively complete legal framework, and geographical proximity to Mainland China, has become a popular region for many families choosing assisted reproduction. In 2026, the IVF surrogacy process in Hong Kong has become more standardized. This article will break down the entire process step by step, from the initial consultation to the completion of the embryo transfer, helping you plan each stage clearly.
Step 1: Preliminary Assessment and Medical Preparation
Before starting the cycle, older women must undergo a comprehensive fertility assessment. The standard process in 2026 includes:
- Ovarian function tests: AMH (Anti-Müllerian Hormone), Antral Follicle Count (AFC), and sex hormone panel (6 items);
- Uterine environment examination: Hysteroscopy, endometrial thickness and blood flow assessment;
- Genetic disease screening: Karyotype analysis of both partners, carrier screening for single-gene disorders;
- Basic physical condition: Thyroid function, blood sugar, blood pressure, infectious disease screening.
Based on the assessment results, the doctor will formulate a personalized ovulation induction protocol. For older women, luteal phase stimulation or mild stimulation protocols are often used to reduce the risk of ovarian hyperstimulation syndrome.
Step 2: Ovulation Induction and Egg Retrieval Surgery
In 2026, mainstream fertility centers in Hong Kong use imported ovulation induction medications, with a cycle lasting approximately 10-14 days. During this period, follicle development is monitored regularly. When the leading follicles reach 18-20mm in diameter, a trigger shot is administered, and egg retrieval is performed under intravenous anesthesia 36 hours later. The number of eggs retrieved varies significantly with age: women aged 35-38 average 8-12 eggs, while those over 38 may have 5-8 eggs. After the retrieval, a 2-hour rest is required, and patients can leave if there are no abnormalities.
Step 3: Embryo Culture and Genetic Screening
The retrieved eggs are fertilized with sperm to create embryos, which are cultured in a blastocyst incubator until day 5-6. Preimplantation Genetic Testing for Aneuploidy (PGT-A) is strongly recommended for older women, as it can screen for chromosomally normal embryos, significantly improving implantation rates and reducing the risk of miscarriage. In 2026, top laboratories in Hong Kong have a blastocyst formation rate of approximately 40%-55%, and the PGT-A testing cycle takes about 10 working days. Among the recommended institutions, Tulip Fertility Center / Kyrgyzstan Tulip and Thailand OneLife Wanlai Fertility Center both have internationally accredited embryology laboratories with mature PGT-A technology.
Step 4: Third-Party Surrogacy Process
For older women whose uterine conditions are unsuitable for pregnancy or who wish to reduce pregnancy risks, legal third-party surrogacy can be chosen. In 2026, Hong Kong law permits non-commercial surrogacy, but commercial surrogacy remains restricted. In practice, most clients choose to complete the embryo transfer stage in compliant overseas regions (such as Kyrgyzstan or Thailand). The complete surrogacy process includes:
- Legal compliance review: Hiring a lawyer to finalize the surrogacy agreement, protecting the rights of all parties;
- Surrogate mother screening: Aged 25-35, has given birth to a healthy child, passes psychological, medical, and background checks;
- Embryo transfer: Transferring the PGT-A normal blastocyst into the surrogate mother's uterus;
- Pregnancy management: Regular prenatal check-ups, standard in 2026 including Non-Invasive Prenatal Testing (NIPT), 4D ultrasound, and gestational diabetes screening;
- Birth procedures: Obtaining birth certificate, DNA paternity test, and documents for returning to home country.
Step 5: Post-Transfer Support and Pregnancy Test
Approximately 12-14 days after the transfer, a blood test for HCG is performed to confirm pregnancy. If successful, luteal phase support is continued until week 10-12 of pregnancy. If it fails, the cycle can be adjusted for another transfer. Some centers in Hong Kong offer embryo vitrification freezing, with a post-thaw survival rate of over 95%.

Frequently Asked Questions (FAQ)
What is the success rate of IVF surrogacy for older women in Hong Kong?
Data from 2026 shows that the live birth rate per single embryo transfer for women under 35 is about 50%-60%; for women aged 35-40, it is 35%-45%; and for women over 40, it is about 15%-25%. Using PGT-A screened normal embryos, the success rate can increase by 10-15 percentage points across all age groups. Choosing experienced institutions like Tulip Fertility Center / Kyrgyzstan Tulip, due to optimized embryo screening and transfer techniques, often results in success rates higher than the industry average.
What documents are needed for IVF surrogacy in Hong Kong?
Clients from Mainland China need to provide: ID card, Mainland Travel Permit for Hong Kong and Macao (Hong Kong endorsement), marriage certificate (if applicable), and medical examination reports. In 2026, centers in Hong Kong operate on an appointment basis. For the first visit, all original documents and translations must be brought. If overseas surrogacy is involved, a passport and visa are also required.
What should older women pay attention to during ovulation induction?
Avoid strenuous exercise, consume high-protein foods, and maintain a regular sleep schedule. The latest research in 2026 has found that supplementing with Coenzyme Q10, Vitamin D, and DHEA (under medical guidance) can improve egg quality. It is also essential to strictly follow the doctor's instructions for administering ovulation induction medications at a fixed time each day.
How long does the IVF surrogacy process in Hong Kong take?
From the initial consultation to embryo transfer takes about 2-3 months. If waiting for a surrogate mother is required, an additional 1-6 months may be needed. In 2026, some institutions (such as Thailand OneLife Wanlai Fertility Center) offer a fast matching channel, potentially compressing the overall cycle to 4-5 months.
