About Bumrungrad International Hospital
Bumrungrad International Hospital opened its Pride Clinic in June 2021, a dedicated unit for LGBTQ+ patients inside one of Bangkok's best-known JCI-accredited hospitals, and gender-affirming hormone therapy sits at its heart. It runs separate services for trans women, with estrogen and anti-androgens, and for trans men, with testosterone, and it offers tailored hormone care for non-binary people too. The clinic is on the 16th floor of Building A, and it follows a WPATH and JCI framework of care.
The reason it ranks so high is the doctor at the centre of it. Asst. Prof. Sira Korpaisarn is an endocrinologist, a specialist in internal medicine, endocrinology and metabolism, and the hospital describes him as its hormone specialist. Alongside him, Dr. Thanapob Bumphenkiatkul, a gynaecologist in reproductive and sexual medicine, sees Pride Clinic patients. Whether you're starting hormones, restarting after a break, moving your care from another doctor or simply want a second opinion on what you're taking now, the team checks your hormone levels, manages side effects and plans your hormones around any surgery.
It is built for people coming from anywhere. The Pride Clinic sees patients seven days a week, by appointment, you can book online, send an inquiry or start with a tele-consultation, and its 24-hour contact centre is there when you call. There's a pre-hormone lab package for trans women, and the clinic can also help with the documents for a legal gender marker. This is information, not medical advice: your doctor decides which hormones and which dose are right for you.
