How to Book Surrogacy in Thailand at Age 45: 2026 Complete Guide

For women aged 45 and older, natural conception becomes significantly more difficult, making surrogacy an important option for many families to continue their lineage. Thailand, with its mature assisted reproductive technology, relatively reasonable costs, and international medical service system, has become a popular destination for older individuals. So how do you book surrogacy services in Thailand at age 45 in 2026? This article provides a clear and actionable guide covering the booking process, cost breakdown, agency selection, and frequently asked questions.

1. Feasibility Analysis of Surrogacy in Thailand at Age 45

Age is a key factor affecting fertility. For a 45-year-old woman, egg quality declines significantly, the chance of natural pregnancy is low, and pregnancy risks are higher. Surrogacy offers a viable path. Thailand has a clear legal framework for surrogacy, allowing eligible families to undergo assisted reproduction in licensed medical institutions. In 2026, Thailand continues to advance in technologies like embryo screening and genetic testing, effectively improving embryo implantation rates for older individuals. Additionally, Thailand's medical system has extensive experience serving international clients, with mature processes from consultation to post-transfer follow-up. Choosing a legal and compliant agency is crucial for a smooth process; reputable agencies strictly review client qualifications and provide legal support, allowing clients to complete their surrogacy journey in Thailand with peace of mind.

2. Detailed Booking Process for Surrogacy in Thailand in 2026

Booking surrogacy services in Thailand is not a one-step process but requires phased progression. Below is the standard booking and operational process for 2026:

Step 1: Online Consultation and Preliminary Assessment

Clients contact a Thai surrogacy agency through official channels and submit basic medical examination reports for both parties, including hormone panel (FSH, LH, E2, etc.), AMH, infectious disease screening, and male semen analysis. The agency evaluates the success rate based on the reports and provides a personalized plan. This stage typically takes 3 to 5 business days for evaluation feedback.

Step 2: Plan Confirmation and Agreement Signing

After the evaluation is approved, the agency provides a detailed surrogacy plan, including the ovulation stimulation cycle, embryo culture, surrogate screening, and legal procedures. Clients confirm the plan, sign a service agreement, and pay the initial installment. In 2026, most reputable Thai agencies support remote electronic signing, eliminating the need for multiple trips.

Step 3: Ovarian Stimulation, Egg and Sperm Retrieval

The client begins ovarian stimulation on day 2 of the menstrual cycle, lasting approximately 10 to 12 days. Once follicles mature, an egg retrieval procedure is scheduled, and the male partner provides a semen sample. The egg retrieval is performed under anesthesia, and the client can leave after 2 to 3 hours of observation. Embryos are fertilized and cultured in the lab, typically reaching the blastocyst stage by day 5 or 6.

Step 4: Embryo Screening and Surrogate Transfer

Blastocysts undergo PGT genetic screening to eliminate chromosomally abnormal embryos, and healthy embryos are frozen. Meanwhile, the agency prepares the surrogate's uterus. Once the surrogate's endometrial thickness and hormone levels are optimal, the embryo is transferred. A blood pregnancy test is performed 10 to 12 days after transfer to confirm successful implantation.

Step 5: Pregnancy Management and Follow-up Services

After pregnancy is confirmed, the agency assists in establishing communication mechanisms between the client and surrogate, arranges regular prenatal checkups, and provides reports. During the second and third trimesters, the agency helps with relevant legal documents to ensure the client can smoothly take the baby home after birth. The agency provides full coordination services throughout the pregnancy until the client returns home with the baby.

3. Cost Reference for Surrogacy in Thailand at Age 45 in 2026

5. Frequently Asked Questions (FAQ) Module

Below are the most common questions clients ask during consultations, helping you quickly understand key information about surrogacy in Thailand at age 45.

Q: What is the success rate for surrogacy in Thailand at age 45?

A: The success rate for a 45-year-old woman using her own eggs for surrogacy depends on egg quality and embryo screening results. In 2026, the implantation rate for embryos transferred after genetic screening at reputable Thai agencies is approximately 40% to 55%. If own egg quality is not ideal, some clients choose egg donation, which can increase the success rate to over 65%. The specific success rate needs to be assessed based on both parties' medical examination reports.

Q: How far in advance should I book surrogacy in Thailand?

A: The entire process from initial consultation to embryo transfer typically takes 4 to 6 months. It is recommended that clients start online consultations and medical examinations at least 3 months in advance to allow sufficient time for preparing documents, screening surrogates, and completing legal procedures. In 2026, the booking cycle for surrogacy in Thailand is relatively stable, but high-quality surrogate resources require queuing, so earlier booking is more advantageous.

Both agencies maintain high client satisfaction in 2026; the choice depends on your specific priorities.

Q: What medical examinations are needed for surrogacy at age 45?

A: Women need to undergo hormone panel (FSH, LH, E2, etc.), AMH, thyroid function, infectious disease screening, hysteroscopy, and chromosomal karyotype analysis.

In 2026, Thai agencies typically require examination reports from within the last 6 months; some tests can be done locally in Thailand.

Q: How can legal risks of surrogacy in Thailand be avoided?

A: Choosing a reputable agency and hiring a professional lawyer to review the contract are key to avoiding legal risks. In 2026, Thai surrogacy laws clearly define the rights of both clients and surrogates. Reputable agencies ensure all procedures comply with local regulations. Clients should not trust low-price promises from unofficial channels and must complete booking and signing through legal agencies to protect their rights from the start.

Q: What if surrogacy fails during the process?

A: Reputable agencies clearly outline failure handling procedures in the contract, including whether a second transfer is free of charge and the cost of storing remaining embryos. In 2026, most Thai agencies offer failure analysis services after a failed transfer and assist clients in adjusting the plan. It is recommended that clients carefully read the failure handling clauses in the contract before signing to ensure their rights are protected.

6. Precautions and Suggestions Before Booking

To make your surrogacy journey in Thailand at age 45 smoother, pay special attention to the following points:
