II. Complete Process Guide for Older Women Undergoing IVF Surrogacy in Thailand

For older women, time is fertility. The following is the standard process for IVF surrogacy in Thailand, where each step directly affects the final outcome:

1. Initial Consultation and Evaluation: Submit basic physical information of both spouses through professional channels, including age, AMH levels, hormone panel, semen analysis, etc. The fertility center will provide personalized plan recommendations based on the evaluation results.
2. First Visit to Thailand and Ovarian Stimulation: Arrive in Thailand on day 2-3 of the menstrual cycle for ultrasound and blood tests. After confirming ovarian status, start ovarian stimulation. Older women typically use mild stimulation or antagonist protocols to reduce the risk of ovarian hyperstimulation.
3. Egg Retrieval and Embryo Culture: Transvaginal egg retrieval is performed under ultrasound guidance, with simultaneous sperm collection. Second or third-generation IVF technology is used for fertilization and embryo culture, culturing to the blastocyst stage on day 5-6.
4. Embryo Genetic Screening: Perform PGT-A screening on blastocysts to select embryos with a normal number of chromosomes. The rate of chromosomal abnormalities in embryos of older women increases with age; this step can significantly improve transfer success rates.
5. Surrogate Preparation and Transfer: Under Thailand's legal surrogacy framework, match a qualified surrogate mother and simultaneously prepare the endometrium. Transfer the selected healthy blastocyst into the surrogate's uterus during the window period.
6. Pregnancy Test and Subsequent Prenatal Care: A blood pregnancy test is performed 10-12 days after transfer. Once pregnancy is confirmed, a professional Thai obstetrics team will follow up throughout the prenatal care until delivery.

The entire cycle takes approximately 45-60 days (excluding the surrogacy pregnancy period). Older women are advised to allow more time for possible adjustments.

VI. Practical Advice for Older Women

Based on years of industry observation and client feedback, the following three points are particularly important for older women planning IVF surrogacy in Thailand:

First, do not blindly pursue low prices. Older women's physical conditions already pose challenges. Choosing low-cost small clinics may involve risks such as outdated laboratory equipment and insufficient embryo culture experience. Prioritize institutions with advanced equipment, internationally accredited laboratories, and a large number of cases involving older women.

Second, value the depth of genetic screening. After age 35, the rate of embryonic chromosomal abnormalities increases exponentially. PGT-A screening can rule out most aneuploid embryos, significantly reducing the risk of miscarriage and birth defects. It is recommended to screen at least 5 embryos for ages 35-38, and more than 8 embryos for ages over 38.

Third, be mentally and time-prepared. The IVF surrogacy cycle for older women may take longer than for younger women, and there may be situations requiring protocol adjustments or repeated cycles. Maintaining a calm mindset and reserving sufficient time and financial flexibility are important guarantees for success.

In 2026, advanced age IVF surrogacy in Thailand presents a more mature and standardized landscape, offering more possibilities for older women in terms of policies, regulations, and medical technology. However, everyone's physical condition and needs are different. It is recommended to obtain personalized evaluation and plan design through professional channels before making a decision.
