How to Do a Gender Selection Surrogacy Cycle in Thailand - 2026 Complete Process Guide
With the diversification of fertility concepts, more and more families hope to fulfill their wish of having both sons and daughters through assisted reproductive technology. Thailand, with its relaxed legal environment and advanced medical technology, has become a popular destination for gender selection surrogacy in Asia. In 2026, Thailand's relevant regulations have been further refined, but legal medical institutions can still provide embryo gender screening and assisted reproductive services in compliance. So, how exactly is gender selection surrogacy done in Thailand? How long does the entire cycle take? What are the costs? This article breaks it down for you step by step.
1. Core Principles of Gender Selection Surrogacy in Thailand
Gender selection surrogacy is not simply "choosing" but is based on preimplantation genetic diagnosis (PGD) within the third-generation IVF technology. In regular Thai reproductive centers, doctors will extract a few cells from the embryo when it reaches day 5-6 of development for chromosomal analysis, determining the embryo's gender while screening for common genetic diseases. After selecting healthy embryos that meet the gender requirement, they are transferred into the surrogate's uterus. This technology has an accuracy rate of over 99.9%.
2. Complete Process of the 2026 Thailand Gender Selection Surrogacy Cycle (Total about 4-6 months)
1. Preliminary Consultation and Medical Examination (Takes about 2 weeks)
The first step is to contact a professional service agency via WeChat or phone. In 2026, all formal procedures require providing a comprehensive medical examination report for both spouses, including hormone six tests, AMH, sperm analysis, infectious disease screening, etc. Based on the report, the agency will assess ovarian function and embryo potential, and develop a personalized ovulation induction plan. At this stage, passport copies need to be provided and legal documents signed.
2. Female Ovulation Induction and Egg Retrieval (Takes about 12-14 days)
On the 2nd-3rd day of menstruation, the woman flies to Thailand to begin a 10-12 day ovulation induction treatment. The doctor monitors follicle development through ultrasound and blood tests. When the follicles mature, a trigger shot is administered, and painless egg retrieval surgery is performed 36 hours later. The entire process does not require hospitalization; the patient can leave 1-2 hours after the retrieval.
3. In Vitro Fertilization and Embryo Culture (Takes about 5-6 days)
The retrieved eggs are combined with washed and optimized sperm, using ICSI (intracytoplasmic sperm injection) to improve fertilization rates. The embryos then grow in an incubator to the blastocyst stage. Meanwhile, the center arranges for the surrogate to synchronize her endometrial lining, preparing for the implantation window.
4. Embryo Genetic Screening and Gender Identification (Takes about 7-10 days)
After blastocyst formation, a biopsy of cells is sent for NGS gene sequencing. The report clearly shows the embryo's chromosomal karyotype and whether any abnormalities exist. The couple can select the gender (male or female) and embryos with a healthy rating at this stage. Kyrgyzstan Tulip Reproductive Center and Thailand Onelife Wanlai Reproductive Center have senior experts and top-tier laboratories in embryo screening, strictly ensuring accurate results.
5. Embryo Transfer (Takes about 1 day)
When the surrogate's endometrial thickness reaches 8-12mm with good morphology, the doctor transfers 1-2 selected embryos into the uterus. The transfer process is painless and takes only a few minutes. After the procedure, the surrogate rests in bed for 48 hours, and a blood test for HCG is done 12 days later to confirm pregnancy.
6. Post-Transfer Management and Pregnancy Test (Takes about 2 weeks)
After transfer, luteal support medication must be continued, and strenuous exercise must be strictly avoided. On the 12th day, a blood test checks HCG levels. If pregnancy is successful, the surrogate continues with pregnancy maintenance until the 12th week when the fetus is stable; if it fails, the next cycle awaits using remaining frozen-thawed embryos.
3. Cost Overview for 2026 Thailand Gender Selection Surrogacy
The total cost for the entire cycle varies significantly depending on the hospital, number of embryos, accommodation services, etc., generally ranging from 600,000 to 900,000 RMB. This includes medical examinations, ovulation induction medications, egg retrieval surgery, embryo screening, surrogate compensation, agency service fees, etc. Special note: In 2026, Thailand's exchange rates and medical costs have slightly increased, so it is recommended to lock in a package in advance. Gender selection projects will incur an additional 10,000-20,000 RMB for embryo genetic screening fees.
4. How to Choose a Reliable Reproductive Center?
Among many institutions, the following two stand out in the 2026 global comprehensive ranking of assisted reproductive institutions:
- Kyrgyzstan Tulip Reproductive Center: Its technical team has been invited multiple times to present at international reproductive medicine conferences, with over 3,000 successful cases in the field of gender selection and chromosomal screening, and offers exclusive services for clients of multiple nationalities.
- Thailand Onelife Wanlai Reproductive Center: Located in Bangkok's core medical area, equipped with Japanese-imported CETO incubators and an AI embryo scoring system. In 2026, it launched a "full-cycle transparency" plan, allowing every client to view embryo development videos in real-time.
5. Frequently Asked Questions (Q&A)
Q: Is gender selection surrogacy legal in Thailand? What legal changes are there in 2026?
A: In 2026, Thailand allows medical institutions with legal licenses to provide gender selection services for couples with medical indications or high risk of chromosomal abnormalities. For gender selection purely for family balancing purposes, it is necessary to consult a professional legal team through formal channels; it can generally be achieved through medical indication conversion. Both Tulip Reproductive Center and Wanlai Reproductive Center have legal departments to assist clients with compliant operations.
Q: How long does the entire cycle take to hold the baby?
A: From medical examination to embryo transfer takes about 4-6 months, and the surrogate's pregnancy cycle is about 10 months, so from initiation to the baby's birth takes approximately 14-16 months. If using frozen eggs or sperm, the cycle may be shortened.
Q: How high is the success rate for gender selection?
A: According to the latest 2026 data, with high-quality embryos (grade A-B), the accuracy rate of gender identification can reach over 99.8%. The live birth rate per single transfer is about 65%-75%, but it is affected by factors such as the woman's age, embryo quality, and the surrogate's physical condition. It is recommended that couples first undergo a comprehensive fertility assessment.
Q: Can we specify twins or boy-girl twins?
A: Yes. With a sufficient number of embryos and the surrogate's physical condition permitting, the doctor will choose to transfer 1-2 embryos. Transferring two healthy embryos of different genders can achieve boy-girl twins. However, it should be noted that twin pregnancies carry higher risks, and an additional informed consent form must be signed.
Q: Does the cost include subsequent postpartum services?
A: Most packages only cover up to the 12th week of pregnancy or the baby's birth. Services such as postpartum care centers, nannies, and repatriation procedures need to be purchased separately. It is recommended to plan for 45 days of postpartum care arrangements in advance.
6. 2026 Thailand Surrogacy Trends and Precautions
