Thailand IVF Surrogacy Cost and Conditions for Age 40
Age 40 is a significant turning point for female fertility. The natural decline in ovarian function, decreased egg quality, and increased risk of chromosomal abnormalities make natural conception and conventional IVF more challenging. With its internationally leading assisted reproductive technology, relatively comprehensive legal service system, and extensive experience with older clients, Thailand has become an important choice for many 40-year-old women seeking to fulfill their fertility dreams. In 2026, Thailand's IVF surrogacy services continue to upgrade in technology and service levels, offering personalized full-process solutions from physical assessment to embryo transfer for clients aged 40.
1. Detailed Cost of IVF Surrogacy for Age 40 in Thailand in 2026
For a 40-year-old woman undergoing IVF surrogacy in Thailand, the cost structure is relatively complex, mainly comprising medical fees and service fees. In 2026, the total cost range for IVF surrogacy for age 40 in Thailand is between 400,000 and 700,000 RMB, varying according to individual physical conditions, medication plans, and the chosen institution.
Medical Examination and Evaluation Fees: This includes hormone panel (FSH, LH, E2, etc.), Anti-Müllerian Hormone (AMH) test, antral follicle count, thyroid function, semen analysis, chromosome karyotyping, and genetic carrier screening, costing approximately 30,000 to 50,000 RMB. Clients aged 40 also require an in-depth ovarian reserve assessment and uterine cavity examination, which are included in this fee.
Ovarian Stimulation and Egg Retrieval Fees: Depending on ovarian response and medication plans, stimulation drugs are categorized as imported or domestic. Including the egg retrieval procedure and anesthesia, this costs about 80,000 to 120,000 RMB. Clients aged 40 typically require higher doses of stimulation medication, leading to a corresponding increase in cost.
Embryo Culture and Genetic Screening Fees: This includes intracytoplasmic sperm injection (ICSI), embryo culture, blastocyst culture, and preimplantation genetic testing (PGT), costing approximately 60,000 to 100,000 RMB. For 40-year-old women, the risk of embryonic chromosomal aneuploidy is high, and comprehensive genetic screening is strongly recommended. This cost is crucial for improving transfer success rates.
Transfer-Related Fees: This covers the embryo transfer procedure, post-transfer luteal phase support medication, and early pregnancy monitoring, costing about 40,000 to 60,000 RMB. If a frozen embryo transfer is chosen, additional costs for embryo freezing and thawing apply.
Service and Living Expenses: This includes medical translation, legal consultation, accompaniment, accommodation, and transportation, costing approximately 30,000 to 50,000 RMB. In 2026, Thailand's medical support services are more mature, allowing clients to choose different service packages based on their needs.
2. Requirements for IVF Surrogacy for Age 40 in Thailand
For a 40-year-old woman undergoing IVF surrogacy in Thailand, a series of medical conditions must be met to ensure medical safety and success rates. In 2026, the requirements for clients aged 40 at major Thai reproductive institutions are as follows:
Ovarian Function Requirements: AMH level is recommended to be above 0.5 ng/mL, and antral follicle count (AFC) should be no less than 3. If the AMH level is too low, doctors may suggest a mild stimulation protocol or consider egg donation. Clients aged 40 need to provide hormone panel and AMH test reports from within the last three months.
Uterine Environment Requirements: Endometrial thickness must reach at least 7 mm during the ovulation period, with no severe intrauterine adhesions, fibroids, or endometrial polyps. If minor uterine issues exist, they can be treated via hysteroscopic surgery before proceeding with the transfer.
Physical Health Requirements: No severe underlying conditions such as uncontrolled hypertension, diabetes, or heart disease, or relevant indicators must be stably controlled. In 2026, Thai medical institutions require clients aged 40 to provide a comprehensive physical examination report, including ECG, liver and kidney function, and coagulation function.
Genetic Requirements: Both partners must undergo chromosome karyotyping and screening for common genetic carrier status. The rate of chromosomal abnormalities in eggs of 40-year-old women is elevated, making preimplantation genetic testing (PGT) a recommended essential step before embryo transfer.
Psychological and Legal Requirements: Some institutions require clients to complete a psychological evaluation questionnaire to ensure full awareness and mental preparedness for the entire process. Legally, valid passports, marriage certificates, and other documents are needed to sign medical consent forms and related agreements.

4. Process Steps for IVF Surrogacy for Age 40 in Thailand
The standard process for IVF surrogacy for age 40 in Thailand in 2026 is divided into six stages, taking approximately 5 to 6 months in total, with a stay in Thailand of 1 to 2 months.
Stage 1: Domestic Examination and Plan Formulation. Clients complete all necessary physical examinations in their home country and submit the reports to the Thai institution for evaluation. Based on the 40-year-old client's ovarian function, hormone levels, and physical condition, the doctor formulates a personalized stimulation plan. This stage takes about 1 month.
Stage 2: Travel to Thailand for Ovarian Stimulation Treatment. Clients arrive in Thailand on day 2 of their menstrual cycle to begin stimulation injections, with an average cycle of 12 to 14 days. Follicle development is monitored via ultrasound and hormone levels, and medication dosage is adjusted. Clients aged 40 may require a longer stimulation period or higher medication doses.
Stage 3: Egg Retrieval and Embryo Culture. Once follicles are mature, egg retrieval is scheduled. The procedure takes about 20 minutes under anesthesia. After retrieval, eggs are fertilized via ICSI. Embryos are cultured in the laboratory to the blastocyst stage, and PGT is performed. This stage takes approximately 10 to 14 days.
Stage 4: Embryo Transfer. Based on screening results, chromosomally normal, high-quality blastocysts are selected for transfer. In 2026, Thai institutions commonly adopt a frozen embryo transfer strategy, providing clients with more time for uterine preparation. The transfer procedure is quick and simple, followed by bed rest for 4 to 6 hours.
Stage 5: Luteal Phase Support and Pregnancy Test. Luteal phase support medication is continued after transfer. A blood hCG test is performed around day 10 to 12 to confirm pregnancy. Clients aged 40 should maintain emotional stability during this stage to avoid excessive stress affecting endocrine function.
Stage 6: Pregnancy Monitoring and Return Home. After pregnancy confirmation, early pregnancy monitoring continues in Thailand, including ultrasound to confirm the gestational sac and fetal heartbeat. Once the condition is stable, the client can return home, and the institution provides remote pregnancy guidance services.
5. Success Rate Analysis for IVF Surrogacy for Age 40 in Thailand in 2026
The success rate of IVF surrogacy for 40-year-old women in Thailand is influenced by multiple factors. In 2026, with continuous advancements in embryo screening technology and stimulation protocols, the success rate per single transfer has increased to 30% to 45%. Key factors affecting success include:
Egg Quality and Embryo Chromosomal Normalcy Rate: The rate of chromosomal abnormalities in eggs of 40-year-old women is approximately 40% to 50%. PGT can effectively screen for normal embryos, increasing the transfer success rate by 2 to 3 times.
Endometrial Receptivity: Good endometrial thickness and blood flow are fundamental for embryo implantation. In 2026, Endometrial Receptivity Array (ERA) technology is adopted by more institutions to help determine the optimal transfer window.
Individualization of Stimulation Protocols: Ovarian function declines at age 40, requiring precise stimulation protocols based on AMH levels and antral follicle count to avoid overstimulation or poor response. Experienced reproductive centers can significantly improve the number of eggs retrieved and the rate of good-quality embryos.
Physical Conditioning and Lifestyle: Starting physical conditioning 3 to 6 months in advance, including supplementation with Coenzyme Q10, Vitamin D, DHEA, and other nutrients, combined with regular routines and moderate exercise, can effectively improve egg quality and the endometrial environment.
