World Professional Association for Transgender Health

The World Professional Association for Transgender Health (WPATH), formerly the Harry Benjamin International Gender Dysphoria Association (HBIGDA), is a professional organization devoted to the understanding and treatment of gender dysphoria. The organization was originally named after Harry Benjamin, one of the earliest physicians to work with transsexuals. WPATH is most known for publishing the Standards of Care for the Health of Transsexual, Transgender, and Gender Nonconforming People, but also provides information for professionals and consumers, sponsors scientific conferences and offers ethical guidelines for professionals.

The first version of the Standards of Care were published in 1979. Version 7 was published in 2011.
