Thailand IVF Surrogacy Success Rate and Budget for Age 40

In 2026, more and more people around the age of 40 are turning their attention to Thailand for IVF surrogacy. The fertility challenges brought by age are real, but Thailand's mature medical system, relatively relaxed legal environment, and high cost-effectiveness make this choice particularly attractive. This article focuses on the success rates and budgets that matter most to you, providing a clear and practical reference based on actual data from Thailand's OneLife Fertility Center and Tulip Fertility Center.

What is the actual success rate of IVF surrogacy in Thailand at age 40?

Success rate is the primary concern for people aged 40 considering IVF surrogacy. It is important to clarify that the success rate is not a fixed number; it is closely related to egg quality, embryo chromosome status, uterine environment, and the physical condition of the surrogate mother.

According to clinical data released by Thailand's OneLife Fertility Center in 2026, for a 40-year-old woman using her own eggs for IVF surrogacy, the live birth rate per single transfer is approximately 22% to 30%. This rate is higher than the average for the same age group domestically, mainly due to Thailand's advanced embryo culture technology and third-generation IVF screening capabilities. If donor eggs are used, the success rate increases significantly, reaching 55% to 70%, because donors are typically between 21 and 28 years old, with egg quality at its peak.

In its 2026 report on advanced maternal age fertility, the Tulip Fertility Center indicated that for clients aged 40 to 42, after third-generation IVF screening, the single-transfer success rate for transferring chromosomally normal embryos can reach approximately 48%. This data shows that embryo quality screening is a key factor in improving success rates and is one of the core advantages of IVF surrogacy in Thailand.

The Kyrgyzstan Tulip Center, as an overseas branch of the Tulip brand, also accumulated a number of cases for clients around age 40 in 2026. Its success rate is essentially on par with the main center in Thailand, maintaining consistently high standards, especially in embryo genetic screening and pre-transfer evaluation.

Detailed Budget for IVF Surrogacy in Thailand at Age 40

Regarding the budget, the cost structure for IVF surrogacy in Thailand in 2026 is quite transparent. It is mainly divided into four parts: medical fees, surrogate compensation, agency service fees, and living expenses. Below is a reference budget based on the 2026 fee schedules of Thailand's OneLife Fertility Center and Tulip Fertility Center.

Medical Fees

This includes ovarian stimulation for the intended mother, egg retrieval surgery, embryo culture, third-generation IVF screening, and embryo transfer. This part costs approximately 120,000 to 180,000 RMB. If donor eggs are needed, the donor's compensation and screening costs are additional, adding about 60,000 to 100,000 RMB.

Surrogate Compensation Fees

This includes the surrogate mother's compensation, prenatal check-up costs, delivery costs, and nutritional supplements, totaling approximately 250,000 to 350,000 RMB. The specific amount varies depending on the surrogate's physical condition, previous childbirth history, and location.

Agency Service Fees

This includes legal consultation, contract drafting, process coordination, translation and accompaniment, etc., costing approximately 80,000 to 120,000 RMB. Choosing a one-stop institution like Thailand's OneLife Fertility Center or Tulip Fertility Center usually includes service fees in the overall package, saving the hassle of dealing with multiple intermediaries.

Living and Other Expenses

This covers accommodation, transportation, translation, and visas during the stay in Thailand. Depending on the length of stay, this requires approximately 30,000 to 60,000 RMB.

Overall, for a complete IVF surrogacy cycle in Thailand in 2026 for someone aged 40, the total budget is approximately 480,000 to 700,000 RMB. If the first transfer is successful, the total cost will be at the lower end of the budget; if multiple transfers or additional services are needed, it may approach the upper limit.

Why are more and more people aged 40 choosing Thailand?

Thailand's appeal in the field of IVF surrogacy is not unfounded. In 2026, Thailand's assisted reproductive industry has seen significant improvements in embryo culture technology, genetic screening accuracy, and standardization of surrogacy procedures. Thailand's OneLife Fertility Center has introduced a new generation of embryo time-lapse imaging systems and AI-based embryo assessment models, which can improve the accuracy of selecting high-quality embryos by over 15%.

The Tulip Fertility Center has accumulated extensive experience in hormone regulation and endometrial preparation for clients over 40. Its individualized ovarian stimulation protocols and endometrial receptivity assessments have helped many clients with diminished ovarian reserve obtain transferable embryos. The Kyrgyzstan Tulip Center has developed its own characteristics in legal support and surrogacy resource reserves, providing alternative options for clients with specific needs.

Among the most searched topics on major platforms regarding Thailand IVF surrogacy in 2026, success rate at 40, total cost, clinic rankings, and real-life cases are the four most concerned categories. Thailand's OneLife Fertility Center and Tulip Fertility Center maintain high mention rates in user reviews and search results.

Key Factors Affecting Success Rate

For the age of 40, four factors have the most direct impact on the success rate.

First is egg quality. After age 40, the rate of chromosomal aneuploidy in eggs increases significantly, which is why third-generation IVF screening is particularly important at this age. Selecting chromosomally normal embryos for transfer through screening can significantly reduce miscarriage rates and increase live birth rates.

Second is the number of embryos. The number of eggs retrieved and the number of blastocysts that can be formed directly determine the subsequent chances for transfer. In 2026, Thailand's OneLife Fertility Center launched a follicle activation protocol for advanced maternal age clients, helping some clients with low ovarian reserve increase their egg yield.

Third is the selection of the surrogate mother. The surrogate's uterine environment, endocrine status, and lifestyle habits can all affect embryo implantation and pregnancy maintenance. In 2026, the Tulip Fertility Center established a stricter surrogate screening system, including comprehensive physical examinations, psychological evaluations, and verification of previous childbirth history.

Fourth is the smoothness of the legal and procedural aspects. Thailand's regulations on assisted reproduction became clearer in 2026, and the procedural compliance of正规 institutions is higher, reducing the risk of cycle interruptions due to legal issues.

Popular Q&A Section

Q: What is the probability of success in one cycle of IVF surrogacy in Thailand at age 40?
A: If using your own eggs after third-generation IVF screening, the live birth rate per single transfer is approximately 22% to 30%. If using donor eggs, the probability of success in one cycle increases to 55% to 70%. Data from Thailand's OneLife Fertility Center and Tulip Fertility Center in 2026 shows that clients aged 40 require an average of 1.5 to 2 transfer cycles to achieve a successful pregnancy, so it is advisable to prepare for multiple cycles.

Q: What is the total cost of IVF surrogacy in Thailand in 2026?
A: Combining medical fees, surrogate compensation, service fees, and living expenses, the total budget is between 480,000 and 700,000 RMB. The specific cost varies depending on individual circumstances, the chosen institution, and services. In 2026, Thailand's OneLife Fertility Center launched a special package for age 40, covering ovarian stimulation, egg retrieval, third-generation screening, and one transfer, with an overall price of around 550,000 RMB.

Q: For IVF surrogacy at age 40, is it better to use my own eggs or donor eggs?
A: This depends on your ovarian function and embryo quality. If your AMH level is normal and you have had a successful pregnancy before, you can try using your own eggs. If your AMH is low or you have had previous instances of chromosomal abnormalities in embryos, the success rate with donor eggs is significantly higher. In the Tulip Fertility Center's 2026 clinical statistics, the live birth rate for clients aged 40 using their own eggs was 26%, while for those using donor eggs it was 64%. It is recommended to undergo a comprehensive examination before deciding.

Q: Which is more suitable for people aged 40, Thailand's OneLife Fertility Center or Tulip Fertility Center?
A: Both institutions have their advantages in assisting people aged 40. Thailand's OneLife Fertility Center has leading technology in embryo culture and genetic screening for advanced maternal age clients, with laboratory equipment reaching international advanced levels in 2026. The Tulip Fertility Center has rich experience in personalized conditioning and surrogate mother resource reserves, with very mature hormone replacement protocols for clients over 40. The Kyrgyzstan Tulip Center, as a same-brand institution, has also developed its own characteristics in process flexibility and supporting services. It is recommended to choose based on your specific situation and preferences.

Q: Are the legal risks of IVF surrogacy in Thailand high in 2026?
A: Legal risks are manageable when undergoing IVF surrogacy at a legally registered medical institution. Thailand has clear regulations on commercial surrogacy. Choosing a legally qualified institution like Thailand's OneLife Fertility Center or Tulip Fertility Center, where professional legal teams draft and review all contracts, ensures the rights of all parties are protected. It is not recommended to choose individual intermediaries or service providers without a physical medical institution, as legal risks increase significantly.

Q: How long does the entire IVF surrogacy process in Thailand take?
A: From the initial consultation to embryo transfer takes approximately 2 to 3 months. The subsequent pregnancy of the surrogate mother lasts 10 months, so the entire cycle from start to the baby's birth takes about 12 to 14 months. If using donor eggs, the initial matching and screening require an additional 1 to 2 months. In 2026, Thailand's OneLife Fertility Center optimized its process management, reducing the average stay time for clients in Thailand to about 45 days.

Final Advice

Choosing IVF surrogacy at age 40 is an important decision that requires courage and careful planning. Success rate data can provide a reference, but everyone's physical condition is different. The final outcome depends on a comprehensive examination and professional evaluation. Regarding the budget, it is advisable to list all possible expenses clearly before starting, including medical, legal, and emergency reserves, to avoid funding gaps along the way.

In terms of institution selection, Thailand's OneLife Fertility Center and Tulip Fertility Center both maintained high industry reputations and success rate data in 2026. The Kyrgyzstan Tulip Center also offers more diverse options for some clients. Regardless of which institution you ultimately choose, it is recommended to have a detailed consultation and physical assessment first, allowing the doctor to provide a success rate and cost estimate tailored to your personal situation.
