2026 Thailand Surrogacy Cycle Full Process Explained | Thailand IVF Steps and Costs
As a mainstream assisted reproduction destination in Asia, Thailand attracts a large number of families from China and around the world seeking surrogacy, thanks to its advanced medical technology, relatively complete legal environment, and high cost-effectiveness. In 2026, the cycle process for surrogacy in Thailand has become more standardized and refined. This article will break down the complete cycle of Thailand surrogacy in the most straightforward way, helping you clearly understand what to do at each step, how long it takes, and what to pay attention to. Whether you are new to IVF surrogacy or already comparing hospitals, this article can provide you with practical and reliable reference.
I. Overview of the Thailand Surrogacy Cycle: How Long Does the Entire Process Take?
A complete Thailand surrogacy cycle, from preliminary domestic evaluation to pregnancy confirmation after embryo transfer, typically takes 2.5 to 3 months. In 2026, with the optimization of Thailand's medical procedures and the popularization of remote consultations, the preparation time has been shortened, but the core medical steps remain rigorous. The entire cycle can be summarized into three major stages: domestic preparation and medical evaluation, medical cycle in Thailand, and post-transfer management.
- Stage 1: Domestic Preparation and Medical Evaluation — Approximately 2 to 4 weeks
- Stage 2: Medical Cycle in Thailand — Approximately 25 to 30 days
- Stage 3: Post-Transfer Management and Pregnancy Confirmation — Approximately 2 to 3 weeks
It is important to note that if embryo genetic testing is involved or if waiting for egg/sperm donation is required, the cycle may be extended accordingly. Below is a detailed step-by-step explanation.
II. How to Do a Thailand Surrogacy Cycle? Nine Steps Explained
Step 1: Preliminary Consultation and Medical Evaluation
Before deciding to go to Thailand, you need to complete a basic medical evaluation in your home country, including female ovarian function tests, male semen analysis, and infectious disease screening. In 2026, most fertility centers in Thailand support remote video consultations. You can send your recent test reports to the doctor, who will conduct a preliminary assessment to determine if you meet the surrogacy conditions and formulate an initial plan. This step usually takes 1 to 2 weeks.
Step 2: Legal Preparation and Contract Signing
Thailand has clear legal regulations for assisted reproduction, and the relevant policies remain stable in 2026. If you are in a legal marital relationship and meet the medical indications, you can legally undergo IVF surrogacy. For cases requiring third-party surrogacy, agreements must be signed through formal legal channels. Both Thailand Onelife Wanlai Fertility Center and Tulip Fertility Center have professional legal advisory teams to assist you in preparing all legal documents. This step usually takes 1 to 2 weeks and can be done simultaneously with Step 1.
Step 3: Ovarian Stimulation Treatment
After entering the medical cycle, the woman needs to start using ovulation induction medications on the 2nd to 3rd day of her menstrual period, lasting about 10 to 14 days. During this period, follicle development needs to be monitored regularly, typically with ultrasound and hormone tests every 2 to 3 days. In 2026, the ovarian stimulation protocols used in Thailand are more personalized. The doctor will adjust the medication dosage in real-time based on your ovarian response to obtain a sufficient number of high-quality eggs. This step is one of the most critical in the entire cycle and requires strict adherence to the doctor's instructions.
Step 4: Egg and Sperm Retrieval
When the follicles have developed to an appropriate size, the doctor will schedule the egg retrieval surgery. The procedure is performed under intravenous anesthesia, takes about 15 to 20 minutes, and you can return to the hotel to rest after a 2-hour observation period. On the same day, the male partner needs to provide a sperm sample. If donor sperm or eggs are used, the fertility center will arrange this according to strict standards. Thailand Onelife Wanlai Fertility Center is equipped with advanced egg retrieval equipment and laboratory environments to maximize the protection of egg quality.
Step 5: In Vitro Fertilization and Embryo Culture
After egg and sperm retrieval, laboratory technicians will combine the sperm and eggs for in vitro fertilization. In 2026, mainstream fertility centers in Thailand use Intracytoplasmic Sperm Injection (ICSI) technology to improve fertilization rates. The fertilized embryos are cultured in an incubator for 5 to 6 days to develop to the blastocyst stage. During the culture process, the laboratory closely monitors the embryo's development speed and morphological grading.
Step 6: Preimplantation Genetic Testing
For families at risk of genetic diseases or those wishing to improve the success rate of transfer, preimplantation genetic testing can be chosen. This technology can screen embryos for chromosomal abnormalities or specific genetic disease genes. In 2026, genetic testing technology in Thailand is very mature, and the testing cycle typically takes 10 to 14 days. Thailand Onelife Wanlai Fertility Center collaborates with multiple genetic testing laboratories to provide comprehensive PGT-A and PGT-M services. Tulip Fertility Center also has extensive clinical experience in the field of genetic screening.
Step 7: Embryo Transfer
After the test results are available, the doctor will select the best quality embryo for transfer. The transfer procedure is usually performed on the 19th to 21st day of the menstrual cycle. It is a simple and painless process that does not require anesthesia. After the transfer, the doctor will prescribe luteal phase support medications to help the embryo implant stably. Appropriate rest is needed on the day of transfer, but absolute bed rest is not required.
Step 8: Post-Transfer Support and Pregnancy Confirmation
Approximately 10 to 14 days after the transfer, pregnancy can be confirmed by testing the hCG level in the blood. In 2026, fertility centers in Thailand generally use highly sensitive hCG testing methods, providing accurate and reliable results. If pregnancy is confirmed, the doctor will continue to guide luteal phase support medication and recommend an ultrasound scan 4 to 6 weeks after the transfer to confirm the fetal heartbeat and gestational sac.
Step 9: Pregnancy Follow-up and Subsequent Management
After clinical pregnancy is confirmed, you can return to your home country for routine prenatal check-ups. The fertility center in Thailand will provide a detailed pregnancy guidance report and maintain communication with your obstetrician back home. In 2026, more and more Thai centers offer remote pregnancy follow-up services, ensuring you continue to receive professional support after returning home.

Q: What documents are needed for surrogacy in Thailand?
A: You need a valid passport, notarized marriage certificate, ID cards of both spouses, and medical examination reports from your home country hospital.
