8 Best Gender Affirming Surgery Clinics in Thailand

Yanhee International Hospital runs its gender affirming surgery program through the Yanhee Pride Center, with separate published pathways for male-to-female and female-to-male care. The male-to-female service page describes genital surgery alongside optional facial feminization, voice and body procedures, while the female-to-male pathway covers a staged sequence from mastectomy and hysterectomy through to phalloplasty. Yanhee states that candidates must have received a psychological evaluation and hormone therapy before surgery, though it does not publish an exact hormone duration or cite WPATH by name. Because Yanhee is a large multi-specialty hospital rather than a boutique clinic, readers whose priority is a single surgeon's personal case volume should confirm which named surgeon within the Pride Center would actually perform their operation before booking.

Bangkok Hospital's headquarters campus runs its program through the Plastic Surgery and Reconstruction Center, and its own sex affirmation surgery page sets out unusually specific admission rules: psychological evaluation by at least two psychiatrists with supporting medical certificates, at least one year living full-time in the identified gender role, and a minimum age of twenty, with parental consent required between eighteen and twenty. Listed techniques include penile skin inversion with or without scrotal graft and two vaginoplasty variants for trans women, and mastectomy, hysterectomy, vaginectomy, metoidioplasty and phalloplasty for trans men. The hospital's separate be YOURSELF unit also publishes pre- and post-surgical hormone management, which is worth checking if ongoing endocrine care after discharge matters to the reader's plan.

Samitivej Sukhumvit Hospital is one of the few providers on this list that names its clinical framework outright: its gender affirmation surgery article states that patients complete a WPATH Version 7 assessment before core procedures such as orchidectomy, vaginoplasty and labiaplasty, with newer techniques including sensate clitoroplasty and endoscopic peritoneal flap vaginoplasty also described. The hospital publishes a specific recovery timeline: five days as an inpatient, walking assistance from around day two, and a stated return to work window of four to eight weeks. Facial feminization, tracheal shave and voice feminization are offered as complementary procedures rather than default inclusions, so patients bundling several surgeries into one trip should confirm scheduling directly with the hospital.

Bumrungrad International Hospital addresses gender affirming surgery through its Pride Clinic, and its gender-affirming surgery page is notably weighted toward trans men's care, describing mastectomy, phalloplasty using forearm or thigh donor tissue, metoidioplasty and laparoscopic hysterectomy with oophorectomy. Vaginoplasty and facial feminization surgery are not detailed on that particular page, so readers seeking those procedures should verify current availability with the clinic before assuming Bumrungrad covers the full spectrum. The hospital states it provides multidisciplinary post-surgical monitoring, pain management and hormone-management support, but it does not publish specific mental health evaluation or hormone therapy duration requirements, so those criteria should be confirmed by direct enquiry.

Preecha Aesthetic Institute (PAI) is the clinic most directly tied to the origin of Thai gender affirming surgery: Assoc. Prof. Dr. Preecha Tiewtranon performed the country's first documented case in 1975, and PAI's Sex Reassignment Surgery service pages now list penile skin inversion, scrotal skin graft and sigmoid colon vaginoplasty options for trans women, plus hysterectomy, mastectomy, metoidioplasty and vaginectomy for trans men. A named team of several plastic and reconstructive surgeons is credited on the site rather than a single practitioner. PAI's published material does not set out an exact hormone therapy duration or a specific age threshold, so readers should request PAI's current written eligibility criteria before assuming any general Thai standard applies to this particular clinic.

Kamol Hospital, also branded Kamol Cosmetic Hospital, centers its program on Dr. Kamol Pansritum, whom the hospital credits with more than 5,000 male-to-female procedures. Its gender reassignment surgery page is unusual for naming five distinct vaginoplasty techniques rather than one default method, from a depth-free external option to colon vaginoplasty and penile-peritoneal vaginoplasty, alongside phalloplasty and metoidioplasty for trans men. Kamol also publishes some of the more specific prerequisites on this list: a minimum age of twenty, at least one continuous year of hormone therapy, at least one year living as the identified gender, a psychiatric assessment certificate, and technique-dependent BMI limits. A stated four to six night inpatient stay and mandatory postoperative dilation are also published, both worth planning around before travel.

Suporn Clinic, roughly 80 kilometers southeast of Bangkok in Chonburi, is narrower in scope than the Bangkok hospitals on this list: its published focus is specifically male-to-female vaginoplasty, using what the clinic calls its own non-penile skin inversion technique alongside a conventional penile-inversion option and a shallow or zero-depth variant. Surgery requiring general anesthetic is carried out at a partnered facility, Samitivej Chonburi Hospital, rather than at the clinic itself, which is worth noting for patients expecting a single-site hospital stay. The clinic states that its total recovery period tends to run longer than is typical elsewhere before resuming intimacy or exertion, so anyone comparing this option against a shorter published Bangkok recovery window should ask Suporn Clinic directly about current expected timelines.

Phuket Plastic Surgery Institute (PPSI) operates inside Bangkok Hospital Siriroj on Phuket and is the only provider on this list based outside Bangkok or Chonburi, which matters for patients who want surgery and recovery on the island rather than traveling to the capital. Its male-to-female gender reassignment page describes penile skin inversion combined with an immediate full-thickness skin graft, without naming individual surgeons, and separately published criteria require patients to be at least 18, with parental permission under 20, plus a referral letter from a psychiatrist, psychiatric social worker or clinical psychologist. PPSI states a comparatively long one to two week inpatient stay after surgery, which should be weighed against shorter stays published by some Bangkok providers when planning travel dates.
