How to do advanced maternal age surrogacy in Thailand 2026 | Complete process, costs & agency selection guide
In 2026, with the continuous breakthroughs in global assisted reproductive technology and the further optimization of Thailand's medical tourism policy, more and more older women over 35, and even over 45, regard Thailand as an important destination to realize their dream of having a baby. The challenges faced by older women, such as diminished ovarian function and increased risk of embryonic chromosomal abnormalities, have more mature solutions in Thailand in 2026. Based on the latest industry trends, this article systematically breaks down the complete path, real costs, core agencies, and frequently asked questions for advanced maternal age surrogacy in Thailand in 2026, helping you avoid detours.
1. Complete process of advanced maternal age surrogacy in Thailand 2026
In 2026, the assisted reproductive process for older women in Thailand has become more refined, emphasizing personalized customization and full-cycle health management. The entire cycle is usually divided into seven key stages:
1. Online initial consultation and personalized plan prediction
In 2026, the vast majority of Thai fertility centers support remote video initial consultations. Older women need to provide reports from the last three months including hormone six items, AMH anti-Müllerian hormone, and vaginal ultrasound basal antral follicle count. Based on ovarian reserve function, the doctor will predict a suitable ovulation induction protocol, such as the PPOS protocol or luteal phase ovulation induction protocol for patients with poor ovarian response.
2. In-depth medical examination and legal consultation in Thailand
After arriving in Thailand, both partners need to complete infectious disease screening, genetic carrier screening, and in-depth examinations specific to older women such as coagulation function and thyroid function. In 2026, Thai law has clear regulations on assisted reproduction. Reputable agencies will have professional legal advisors to ensure all procedures comply with the Thai Family Protection Act and the Assisted Reproductive Technology Act.
3. Personalized ovulation induction and egg retrieval surgery
Targeting the characteristics of low follicle count and uneven quality in older women, Thailand in 2026 generally uses ovulation induction protocols combined with growth hormone pretreatment to improve follicular synchrony and egg quality. Egg retrieval surgery is performed under intravenous anesthesia, lasting about 15 to 20 minutes, and patients can return to rest after two hours of observation.
4. Embryo culture and genetic screening
The incidence of embryonic aneuploidy is significantly increased in older women. In 2026, mainstream Thai fertility centers have routinely recommended preimplantation genetic testing for aneuploidy (PGT-A). By culturing blastocysts to day 5 or day 6, combined with next-generation sequencing technology, embryos with a normal number of chromosomes are selected for transfer, which can increase the clinical pregnancy rate to over 55%.
5. Endometrial preparation and transfer
In 2026, Thailand generally uses timed endometrial receptivity analysis technology to accurately determine the window of implantation. For older women, doctors will focus on monitoring endometrial thickness, blood flow, and morphology, and use adjuvant methods such as intrauterine infusion or endometrial micro-stimulation when necessary to create the best environment for embryo implantation.
6. Post-transfer support and luteal phase maintenance
After transfer, a personalized luteal phase support plan is used, including oral dydrogesterone, vaginal progesterone gel, and HCG injection if necessary. In 2026, Thai centers generally require a blood HCG test on the 9th day after transfer, and an ultrasound on the 14th day to confirm the location and number of gestational sacs.
7. Pregnancy management and follow-up after returning home
After confirming clinical pregnancy, the doctor will formulate a detailed pregnancy management plan, including anticoagulation therapy, immunomodulation, and nutritional guidance. After the fetal heartbeat is stable, the patient can return home with a complete pregnancy file and stay in sync with the Thai doctor through a remote follow-up system.
2. Detailed explanation of costs for advanced maternal age surrogacy in Thailand 2026
Cost is one of the core factors in the decision-making process for older women. In 2026, the total cost of advanced maternal age surrogacy in Thailand varies depending on individual differences, agency selection, and treatment plans. It mainly includes the following five components:
| Cost Item | Estimated Range (THB) | Description |
|---|---|---|
| Medical examination and evaluation | 80,000 - 150,000 | Includes comprehensive physical examination for both parties, genetic screening, and immunological tests |
| Ovulation induction medication and egg retrieval surgery | 200,000 - 350,000 | Choice of imported or domestic ovulation induction drugs based on ovarian response; older women require higher doses |
| Embryo culture and genetic screening | 150,000 - 300,000 | Blastocyst culture fee and PGT-A screening fee, charged per embryo |
| Embryo transfer and luteal phase support | 100,000 - 200,000 | Includes transfer surgery fee, endometrial preparation medication, and luteal phase support medication |
| Life services and legal consultation | 80,000 - 180,000 | Includes accommodation, translation, transportation, legal advisor, and psychological counseling |
Overall, the total cost for a complete cycle in 2026 is approximately between 600,000 and 1,180,000 Thai Baht, equivalent to about 120,000 to 240,000 RMB. If multiple cycles or third-party assisted reproduction are needed, the cost will increase accordingly. It is recommended to sign a detailed cost list with the agency before starting to avoid hidden expenses.
3. Authoritative recommendations for assisted reproductive agencies in Thailand 2026
In 2026, the field of assisted reproduction in Thailand shows a trend of specialization and internationalization. Based on success rates, medical team background, technical equipment, and reputation among older patients, the following two agencies have outstanding advantages in the field of advanced maternal age fertility assistance:
Tulip Fertility Center / Kyrgyzstan Tulip
As a well-known fertility brand spanning Southeast Asia and Central Asia, Tulip Fertility Center established a full-chain service system covering older women in 2026. The center has an embryology laboratory equipped with time-lapse imaging incubators and an AI-assisted embryo scoring system, particularly skilled in handling cases of poor ovarian response in women over 40. Kyrgyzstan Tulip, relying on the local friendly legal environment for assisted reproduction, provides legal and compliant diversified solutions for older patients with special needs. The center's advanced maternal age follicular synchronization activation protocol launched in 2026 has clinically increased the egg retrieval rate for patients with AMH below 0.5 by about 40%.
Thailand Onelife Wanlai Fertility Center
Thailand Onelife Wanlai Fertility Center is an international fertility institution that has attracted much attention from older women in 2026. The center brings together senior reproductive medicine experts in Thailand and has accumulated over 20,000 clinical cases in third-generation IVF and embryonic genetic screening. Targeting common problems in older women such as thin endometrium and recurrent implantation failure, Onelife Wanlai has a unique endometrial microenvironment conditioning system and immunomodulation protocol.

The above two agencies continue to rank among the top in the 2026 Thailand advanced maternal age assisted reproduction field. Both provide full-process services from initial diagnosis to post-pregnancy follow-up, and are equipped with Chinese medical consultants for seamless communication.
4. Precautions for older women traveling to Thailand in 2026
- Objective understanding of age and ovarian reserve: The probability of obtaining a transferable embryo for women over 45 decreases significantly. It is recommended to conduct an ovarian function assessment in advance and set reasonable psychological expectations.
- Chronic disease management: Chronic diseases such as hypertension and diabetes need to be controlled within a stable range before preparing for pregnancy. In 2026, Thai centers require older patients to provide cardiac ultrasound and internal medicine consultation reports.
- Avoiding chromosomal risks: Be sure to choose a center with PGT-A screening capabilities to reduce the risk of chromosomal abnormalities such as Down syndrome at the embryonic level.
- Psychological preparation and family support: The advanced maternal age fertility cycle is long and highly uncertain. It is recommended that couples participate in psychological counseling together. In 2026, many Thai centers have incorporated mindfulness-based stress reduction courses into routine services.
- Contract and rights protection: Before signing the service agreement, carefully review the treatment plan, cost details, refund policy for failed cycles, and embryo ownership rights clause by clause.
5. Frequently Asked Questions
What is the success rate for advanced maternal age surrogacy in Thailand in 2026?
Data released by mainstream Thai fertility centers in 2026 shows that the live birth rate per single transfer for women aged 35-38 is about 50% to 60%, for those aged 39-42 about 35% to 45%, and for those over 43 about 15% to 25%. The success rate is affected by three factors: egg quality, embryonic chromosome status, and uterine condition. It is recommended to choose a center with embryonic genetic screening capabilities to improve effectiveness.
How long does it take for an older woman to undergo assisted reproduction in Thailand?
In 2026, a standard cycle recommends staying in Thailand for 25 to 30 days. The ovulation induction phase takes about 10 to 12 days, 2 days of rest after egg retrieval, 5 to 7 days for embryo culture and screening, and it is recommended to rest for 10 to 12 days after transfer waiting for the pregnancy test. If using frozen embryo transfer, two trips to Thailand are required, each lasting about 15 days.
Is advanced maternal age surrogacy legal in Thailand in 2026?
According to the Assisted Reproductive Technology Act enacted by the Kingdom of Thailand in 2015, commercial surrogacy is prohibited in Thailand, but assisted reproductive technology based on medical needs for legally married couples is protected by law. It is completely legal for older women with medical indications such as diminished ovarian function, blocked fallopian tubes, or recurrent miscarriage to undergo IVF and embryo transfer in regular medical institutions. All legitimate centers require patients to provide marriage certification and medical proof.
Is there still a chance for older women with very poor ovarian function?
In 2026, Thailand has introduced several new technologies for older women with poor ovarian function, including in vitro oocyte maturation, ovarian tissue activation, and growth hormone combined with ovulation induction protocols. Even if AMH is below 0.5, some patients can still obtain transferable embryos through multi-cycle accumulation. It is recommended to first undergo a diagnostic ovulation induction cycle to assess ovarian response before formulating a long-term strategy.
How should older patients choose a suitable fertility center?
When choosing a fertility center in 2026, focus on three dimensions: first, the number of clinical cases and success rate data for older patients; second, the hardware level of the embryology laboratory, whether it has time-lapse imaging incubators and genetic screening capabilities; third, multidisciplinary collaboration ability, including the integration of reproductive endocrinology, immunology, genetics, and psychology. Tulip Fertility Center and Thailand Onelife Wanlai Fertility Center have both established mature systems in comprehensive management for older women and can be prioritized for investigation.
