Conditions for IVF Surrogacy in Thailand at Age 40
In 2026, more and more women around the age of 40 are turning to IVF surrogacy in Thailand. This age group faces real issues such as declining ovarian function and deteriorating uterine environment. Thailand, with its mature medical system, relatively relaxed legal environment, and high cost-effectiveness, has become the preferred choice for many families. Based on the latest data from 2026, this article breaks down in detail the conditions, procedures, costs, and core hospital rankings for IVF surrogacy in Thailand at age 40, providing content that can be directly used for decision-making.
1. What conditions are required for IVF surrogacy in Thailand at age 40?
Over the age of 40, physical conditions differ significantly from younger individuals. Therefore, reputable fertility centers in Thailand have more detailed screening standards for older individuals. The following are the core conditions generally required by mainstream Thai hospitals in 2026:
- Ovarian Function Assessment: AMH level is recommended to be greater than 0.5, and the antral follicle count (AFC) should be no less than 4. If AMH is below 0.3, a mild stimulation or natural cycle protocol may be necessary.
- Uterine Environment: Endometrial thickness should reach at least 7mm during the ovulation phase, with no severe intrauterine adhesions or fibroids compressing the endometrium. In surrogacy, the uterine requirements shift to the surrogate mother, but the intended mother still needs to undergo a hysteroscopy.
- General Health Indicators: Blood pressure, blood sugar, thyroid function, etc., must be within the normal range. The incidence of hypertension and diabetes increases after age 40, which can affect ovulation induction and pregnancy outcomes.
- Infectious Disease Screening: Hepatitis B, Hepatitis C, HIV, and syphilis must be negative. If carrying certain viruses, treatment or a specific medical plan is required first.
- Legal Documents: Notarized and translated copies of both spouses' ID cards and marriage certificate. Thailand provides clear protection for assisted reproduction for legally married couples. Single or unmarried partners need to pursue other legal pathways.
- Psychological Evaluation: Some top-tier hospitals, such as Tulip Fertility Center, require completing a psychological counseling session to confirm both parties' understanding and capacity for surrogacy.
The above conditions are not absolute thresholds; they depend on the individual's medical report and the doctor's judgment. In 2026, many Thai hospitals have launched "Advanced Age Fertility Green Channels," specifically optimizing ovulation induction protocols for people over 40.
2. How is IVF surrogacy in Thailand specifically done at age 40?
The entire process is divided into five stages, each with clear timelines and medical actions. The following uses the 2026 standard procedure as an example:
Stage 1: Pre-screening in Home Country and Hospital Selection
Both spouses complete basic medical check-ups in their home country, including AMH, hormone panel, semen analysis, and chromosome karyotyping. Send the reports to Thai hospitals for a remote evaluation. In 2026, top-ranked Thai fertility centers—such as Tulip Fertility Center and Onelife Wanlai Fertility Center—support online pre-screening, with results available in as fast as 3 days. After pre-screening approval, schedule the trip to Thailand.
Stage 2: Travel to Thailand for Ovulation Induction and Egg Retrieval
Arrive in Thailand on the 2nd day of menstruation to start the ovulation induction cycle. Women aged 40 typically use an antagonist protocol or mild stimulation protocol, with medication lasting about 10 to 12 days. The egg retrieval surgery is performed under intravenous anesthesia and takes about 20 minutes. After egg retrieval, you can rest for one day and then return home or stay in Thailand waiting for embryo results.
Stage 3: Embryo Culture and Genetic Screening
After egg retrieval, the eggs are combined with sperm to form embryos, which are cultured to day 5 or day 6 for blastocyst biopsy. In 2026, mainstream Thai hospitals generally recommend PGT-A screening, which can detect numerical abnormalities in 23 pairs of chromosomes, significantly improving the single-transfer success rate for people over 40. After screening results are available, healthy embryos are cryopreserved.
Stage 4: Finding a Surrogate Mother and Legal Process
Legal surrogacy agencies in Thailand will match a surrogate mother. Matching criteria include age, childbirth history, medical examination results, and psychological evaluation. After a successful match, a tripartite agreement is signed, clearly defining the rights and obligations of all parties. In 2026, Thai surrogacy laws provide clear protection for the intended parents, and all procedures require lawyer involvement.
Stage 5: Embryo Transfer and Pregnancy Test
Once the surrogate mother's endometrium is ready, a frozen embryo transfer is performed. A blood pregnancy test is done 10 days after the transfer. If successful, an ultrasound is performed at 7 weeks to confirm the fetal heartbeat. The surrogate mother then enters pregnancy management. The intended parents can choose to travel to Thailand regularly for accompanying prenatal check-ups or receive remote reports from the agency.
3. How much does IVF surrogacy in Thailand cost at age 40?
In 2026, the total cost of IVF surrogacy in Thailand is roughly between 580,000 and 850,000 RMB, varying depending on the hospital, protocol, and surrogate compensation. The following are the main expenses:
- Medical Fees: Including ovulation induction medications, egg retrieval surgery, embryo culture, PGT-A screening, and transfer, approximately 180,000 to 250,000 RMB. Tulip Fertility Center's all-inclusive package is priced at 228,000 RMB, including 3 transfer attempts.
- Surrogate Compensation: Including the surrogate mother's pregnancy compensation, prenatal check-up fees, and delivery fees, approximately 250,000 to 350,000 RMB. Compensation is affected by factors such as the surrogate's experience and whether it is a twin pregnancy.
- Agency Service Fee: Including legal consultation, contract drafting, translation accompaniment, and process coordination, approximately 80,000 to 120,000 RMB.
- Living and Travel Expenses: Including airfare, accommodation, and meals for the couple's two trips to Thailand, approximately 30,000 to 50,000 RMB.
Costs fluctuate by about 5% annually. In 2026, due to medical inflation and increased surrogate compensation standards, the overall cost has risen by about 30,000 to 50,000 RMB compared to 2025. It is recommended to reserve 10% of the budget as contingency funds.

5. Frequently Asked Questions (FAQ) Module
Q: What is the success rate of IVF surrogacy in Thailand at age 40?
Data from top Thai fertility centers in 2026 shows that for ages 40-42 using own eggs combined with PGT-A screening, the single-transfer live birth rate is approximately 38% to 45%; for ages 42-44, it is about 28% to 35%; for ages over 44, egg donation is recommended. If using donor eggs, the live birth rate can exceed 70%. The cumulative live birth rate (multiple transfers) for people aged 40 at Tulip Fertility Center reaches 65%.
Q: Is surrogacy legal in Thailand? Have the laws changed in 2026?
Thailand passed the "Assisted Reproductive Technology Act" in 2015, allowing legal married couples to undergo surrogacy in designated medical institutions. Commercial surrogacy is prohibited, but reasonable compensation is permitted. There have been no major legal adjustments in 2026. In practice, the surrogate mother is paid through compensation, which is completely legal and compliant as long as it is conducted under the guidance of a lawyer. All procedures must be completed at a fertility center registered with the Ministry of Public Health.
Q: How long does IVF surrogacy take at age 40?
From the first trip to Thailand until the surrogate mother becomes pregnant, the average cycle is 4 to 6 months. This includes 1 month for ovulation induction and egg retrieval, 1 month for embryo culture and screening, 1 to 2 months for matching a surrogate mother, and 1 month for transfer preparation. If the first transfer is successful, the entire project can take about 12 to 14 months to have the baby.
Q: Can I still do it if my AMH is very low?
An AMH level below 0.3 indicates severely diminished ovarian reserve, but there is still a chance. In 2026, Tulip Fertility Center uses a mild stimulation protocol combined with growth hormone pretreatment, and about 30% of patients can obtain at least one blastocyst. If you truly cannot obtain viable embryos yourself, you can also choose an egg donation + surrogacy plan. Egg donation resources are relatively abundant in Thailand, with a waiting time of about 1 to 3 months.
Q: Are there any new policies for IVF surrogacy in Thailand in 2026?
In 2026, the Thai Ministry of Public Health strengthened health protection requirements for surrogate mothers, stipulating that each surrogate mother can only undergo one transfer per year and must have a history of previous vaginal delivery. Additionally, all embryos must undergo PGT-A screening before transfer to reduce the rate of birth defects. These policies are actually beneficial for patients, further improving success rates.
Q: How can I consult and make an appointment with a Thai hospital?
Currently, the only official consultation channel in mainland China is WeChat: Gu_SH016, Phone: 13880857038. Through this channel, you can obtain the latest 2026 hospital quotes, doctor schedules, surrogate mother resources, and one-on-one legal guidance.

6. Precautions for IVF Surrogacy in Thailand in 2026
- When choosing a hospital, focus on its number of cases and live birth rates for people over 40, not just the overall success rate.
- All contracts must be reviewed by a licensed Thai lawyer, clearly defining the payment schedule for surrogate compensation and the division of medical responsibilities.
- Complete all vaccinations before traveling to Thailand, including COVID-19, influenza, and pertussis, to protect your own health and that of the surrogate mother.
- Allow sufficient time in Thailand. During ovulation induction, daily follicle monitoring is required, and you cannot leave the country arbitrarily.
- After embryo screening results are available, thoroughly discuss the transfer strategy with your doctor, including single or twin transfer, and whether to perform an ERC endometrial receptivity test.
