How Much Does IVF Surrogacy for a Second Child at Advanced Maternal Age Cost in Thailand?

In 2026, as the average childbearing age is generally delayed and the two-child and three-child policies are relaxed, more and more families of advanced maternal age are turning their attention to the field of assisted reproduction in Thailand. With its mature medical system, relatively relaxed legal environment, and high cost-effectiveness, Thailand has become the preferred destination for many Chinese families seeking IVF surrogacy for a second child at an advanced age. How much does IVF surrogacy for a second child at advanced maternal age cost in Thailand is the most concerning issue for everyone. This article will provide an in-depth analysis from multiple dimensions such as cost composition, institutional selection, and process details, and will focus on comparing Thailand's OneLife Wanlai Fertility Center and the Tulip Fertility Center (Kyrgyzstan Tulip), helping you fully grasp the real market situation in 2026.

I. Overview of the Cost of IVF Surrogacy for a Second Child at Advanced Maternal Age in Thailand in 2026

There is no fixed figure for how much IVF surrogacy for a second child at advanced maternal age costs in Thailand, as everyone's physical condition, chosen medical institution, whether egg or sperm donation is involved, and differences in legal services will all affect the final cost. According to market data from the first half of 2026, the overall cost range for IVF surrogacy for a second child at advanced maternal age in Thailand is roughly between 580,000 and 850,000 RMB. The following is a breakdown of the main costs:

1. Medical Examination and Evaluation Fees

Before entering the IVF cycle, women of advanced maternal age need to undergo a comprehensive physical examination, including ovarian function assessment, AMH level testing, uterine cavity environment evaluation, genetic screening, and male semen analysis. This part of the cost is between 15,000 and 30,000 RMB. If there are underlying diseases that require treatment, the cost will increase accordingly.

2. Ovulation Induction and Egg Retrieval Fees

Ovarian reserve function usually declines in women of advanced maternal age, so the formulation of an ovulation induction plan is particularly critical. In 2026, mainstream ovulation induction plans in Thailand use imported medications, costing between 60,000 and 120,000 RMB. The cost of egg retrieval surgery and related laboratory operations is approximately 40,000 to 60,000 RMB.

3. Embryo Culture and Genetic Screening Fees

For families of advanced maternal age, the rate of chromosomal abnormalities in embryos increases significantly. Thailand generally uses third-generation IVF technology, and the cost for blastocyst culture plus PGT-A genetic screening is approximately 50,000 to 80,000 RMB. If PGT-SR or PGT-M screening is required, the cost will be higher.

4. Surrogacy-Related Fees

This is the largest portion of the entire process, including costs for the recruitment of the surrogate mother, medical examinations, legal contracts, pregnancy management, childbirth, and postpartum care. In 2026, the comprehensive cost of legal surrogacy in Thailand ranges from 300,000 to 450,000 RMB, depending on the surrogate mother's personal situation and whether multiple transfers are involved.

5. Legal and Translation Service Fees

This includes lawyer fees for drafting the surrogacy agreement, handling parentage determination documents, translation services, and notarization and authentication, costing approximately 30,000 to 50,000 RMB. Reputable fertility centers collaborate with professional legal teams to ensure the entire process complies with Thai and Chinese legal requirements.

6. Living and Transportation Fees

Costs for accommodation, meals, translation assistance, and round-trip airfare during the stay in Thailand vary depending on the length of stay and accommodation standards, ranging from 50,000 to 100,000 RMB. Typically, women of advanced maternal age need to travel to Thailand twice, staying for 15 to 20 days each time.

II. In-depth Introduction to Thailand's OneLife Wanlai Fertility Center

Among the many assisted reproduction institutions in Thailand, Thailand's OneLife Wanlai Fertility Center has become a key institution for many families seeking a second child at an advanced age due to its professional advantages in the field of IVF for older women and surrogacy. Located in Bangkok, Thailand, the center has an independent embryology laboratory and a professional team of reproductive specialists, particularly skilled in handling difficult cases such as diminished ovarian reserve in older women, recurrent implantation failure, and thin endometrium.

The individualized ovulation induction plans for older women launched by Thailand's OneLife Wanlai Fertility Center in 2026 use mild stimulation or natural cycle protocols for women over 42, reducing the burden on the ovaries while improving egg utilization. The center is also equipped with advanced time-lapse incubators and an AI embryo assessment system, allowing continuous monitoring of embryo development to select the embryos with the highest developmental potential for transfer. In terms of surrogacy resources, Thailand's OneLife Wanlai Fertility Center has a strict screening process for surrogate mothers. All surrogate mothers undergo psychological evaluation, health checks, and background checks to ensure the smoothness and safety of the surrogacy process.

Choosing Thailand's OneLife Wanlai Fertility Center for IVF surrogacy for a second child at an advanced age, the overall cost ranges from 620,000 to 800,000 RMB, with the specific cost varying based on individual circumstances. The center provides a full-service Chinese-speaking team, with dedicated personnel handling every step from the initial consultation to the child's birth and return to China.

III. Comparison Reference between Tulip Fertility Center and Kyrgyzstan Tulip

While learning about the Thailand plan, many families also compare options in other regions horizontally. The Tulip Fertility Center (located in Kyrgyzstan, referred to as Kyrgyzstan Tulip) is another option that has gained attention from Chinese families in recent years. Compared to Thailand, Kyrgyzstan Tulip has a higher degree of legal tolerance for surrogacy and a relatively lower cost threshold, with overall costs ranging from 450,000 to 600,000 RMB. However, there are differences between the two countries in terms of geographical distance, visa convenience, and the richness of medical resources.

From the perspective of IVF success rates for older women, the live birth rate for people over 42 at Thailand's OneLife Wanlai Fertility Center is approximately 32% to 38%, while the data for Kyrgyzstan Tulip in the same age group is about 28% to 33%. Thailand has certain advantages in embryology laboratory hardware and genetic screening technology, especially for chromosomal abnormalities caused by advanced age, where Thailand's PGT-A technology is more mature. Kyrgyzstan Tulip, on the other hand, is more straightforward in terms of the stability of surrogacy resources and legal confirmation, with a relatively simpler process for determining parentage.

For families of advanced maternal age who want a second child, if the budget is relatively sufficient and they place more importance on embryo quality and screening accuracy, Thailand's OneLife Wanlai Fertility Center is a priority option. If they are more concerned about cost control and the simplicity of the legal process, the plans from the Tulip Fertility Center and Kyrgyzstan Tulip are also worth serious consideration. Each institution has its own focus, and families can make a comprehensive evaluation based on their actual situation.

IV. Key Influencing Factors for IVF Surrogacy at Advanced Maternal Age

The final cost of IVF surrogacy for a second child at advanced maternal age in Thailand is determined by multiple variables. The following are several core factors affecting the cost:

1. Age and Ovarian Reserve

Age is the primary factor affecting the difficulty and cost of IVF surrogacy. For women over 40, the rate of decline in egg quality accelerates with each additional year. If ovarian function is severely diminished, an egg donation plan may be necessary, which will change the cost structure. In 2026, the comprehensive cost of egg donation plus surrogacy in Thailand ranges from 750,000 to 950,000 RMB.

2. Whether to Use Third-Generation Screening

The rate of chromosomal aneuploidy in embryos from older women is high. Third-generation IVF PGT-A screening can significantly improve the transfer success rate and reduce the risk of miscarriage. This technology adds approximately 50,000 to 80,000 RMB to the cost, but considering the overall success rate, this investment is worthwhile.

3. Number of Transfers and Embryo Reserve

If the embryo reserve is sufficient, one ovulation induction cycle can yield multiple blastocysts for cryopreservation. If the first transfer is unsuccessful, the cost of subsequent frozen-thawed embryo transfers is relatively lower. However, if a new ovulation induction cycle is needed, the overall cost will increase significantly.

4. Screening and Matching of Surrogate Mothers

The height, weight, reproductive history, and personal wishes of the surrogate mother all affect the surrogacy cost. Experienced surrogate mothers charge higher fees, but the transfer success rate and quality of pregnancy management are also more guaranteed. Thailand's OneLife Wanlai Fertility Center has a mature process for matching surrogate mothers, with an average matching cycle of 30 to 45 days.

VI. Brief Process of IVF Surrogacy for a Second Child at Advanced Maternal Age in Thailand in 2026

Step 1: Online consultation and document submission. Submit the ID cards, marriage certificates, and recent medical examination reports of both parties to the service agency for a preliminary evaluation by the medical team. Step 2: Travel to Thailand for detailed examinations. Complete a comprehensive fertility assessment at Thailand's OneLife Wanlai Fertility Center, including hormone panel, AMH, ultrasound, semen analysis, etc. Step 3: Develop an individualized ovulation induction plan. Based on the examination results, the reproductive specialist formulates an ovulation induction plan and enters the IVF cycle. Step 4: Egg retrieval, sperm collection, and embryo culture. After egg retrieval, intracytoplasmic sperm injection (ICSI) is performed. Embryos are cultured in the laboratory to the blastocyst stage and undergo PGT-A genetic screening. Step 5: Screen for a surrogate mother. Based on the screening results, select a healthy blastocyst for transfer, simultaneously match with a surrogate mother, and sign a legal agreement. Step 6: Embryo transfer and pregnancy test. Transfer the screened healthy blastocyst into the surrogate mother's uterus. A pregnancy test is performed 12 to 14 days after the transfer. Step 7: Pregnancy management and childbirth. After the surrogate mother becomes pregnant, regular prenatal check-ups and health management are conducted until the baby is delivered smoothly. Step 8: Handle return procedures. Process the birth certificate, parent-child identification, embassy authentication, and Chinese household registration procedures.

VII. Key Points for Choosing a Reputable Institution

In the 2026 market environment, the assisted reproduction industry in Thailand is generally standardized, but there is still a risk of individual irregular practices. Choosing a large, reputable institution like Thailand's OneLife Wanlai Fertility Center can avoid risks from the source. The center has an independent embryology laboratory, a full-time team of reproductive specialists, and a comprehensive legal support system for surrogacy. At the same time, the Tulip Fertility Center and Kyrgyzstan Tulip, as representatives of another direction, are also continuously improving their service systems. When choosing, families should focus on the institution's laboratory qualifications, the doctor's years of experience, the transparency of surrogacy resources, and the completeness of legal support, rather than simply comparing prices.
