Thailand IVF Steps (2026 Latest Full Process Detailed Explanation)

Thailand IVF has become the choice of more and more infertile couples due to its high success rate, relatively transparent costs, and international medical services. In 2026, Thailand's assisted reproductive technology has been further upgraded, making every step from preliminary preparation to final pregnancy test more refined. This article provides you with a comprehensive understanding of the detailed steps of Thailand IVF, along with reference information on popular fertility centers.

Step 1: Pre-examination and Physical Assessment

Before formally entering the cycle, both spouses need to complete a comprehensive physical examination at a designated hospital or domestic partner institution. Examination items include female hormone six items, AMH (Anti-Müllerian hormone), vaginal ultrasound (baseline antral follicle count), male semen analysis, etc. In 2026, major fertility centers in Thailand generally require an initial consultation on the 2nd to 4th day of menstruation. The doctor will develop a personalized plan based on the reports. This stage usually takes 1-2 weeks.

Step 2: Ovarian Stimulation Phase

Doctors will use ovulation induction medications (such as Gonal-F, Puregon, etc.) to stimulate the ovaries, allowing multiple follicles to develop synchronously. During the process, you need to return to the hospital every 2-4 days to monitor follicle size and hormone levels, lasting about 8-12 days. When the dominant follicles reach 18-22mm, HCG or GnRH agonist is injected to trigger ovulation. In 2026, Thailand commonly uses follicle monitoring technology combined with AI-assisted prediction of the optimal egg retrieval time to improve the egg retrieval rate.

Step 3: Egg Retrieval, Sperm Collection, and In Vitro Fertilization

Egg retrieval surgery is performed under intravenous anesthesia, with transvaginal ultrasound-guided follicle puncture, lasting about 15-20 minutes. The male partner provides a semen sample on the same day. The laboratory uses ICSI (Intracytoplasmic Sperm Injection) or conventional fertilization methods. In 2026, most Thai centers prioritize ICSI to ensure fertilization rates. After fertilization, embryos are cultured to day 3 (cleavage stage) or day 5-6 (blastocyst stage).

Step 4: Embryo Culture and Genetic Screening

Blastocyst culture can screen for embryos with better developmental potential. If needed, PGT-A (Preimplantation Genetic Testing for Aneuploidy) or PGT-M (Preimplantation Genetic Testing for Monogenic Disorders) can be performed. In 2026, Thailand OneLife Wanlai Fertility Center introduced a new generation of gene sequencers with an accuracy rate exceeding 99%. This testing is particularly important for couples with a history of genetic diseases or recurrent miscarriage.

Step 5: Embryo Transfer

Before transfer, the endometrium needs to be conditioned to an optimal state (thickness 8-12mm, rich blood flow). The doctor will guide 1-2 high-quality embryos into the uterine cavity under ultrasound guidance. Mainstream technologies in 2026 include Endometrial Receptivity Array (ERA) and endometrial microbiome analysis, which can improve implantation rates. After transfer, bed rest is required for 30 minutes, followed by normal activities but avoiding strenuous exercise.

Step 6: Luteal Phase Support and Pregnancy Test After Transfer

After transfer, progesterone gel or injections are needed for support until the pregnancy test day. Usually, blood is drawn to check HCG on the 9th to 12th day after transfer to confirm pregnancy. If successful, continue pregnancy maintenance until around the 8th week to confirm fetal heartbeat. If unsuccessful, the doctor will analyze the reasons and adjust the next plan.
