The World Professional Association for Transgender Health, Inc. (WPATH) (formerly, the Harry Benjamin International Gender Dysphoria Association, Inc. (HBIGDA)) is a professional organization devoted to the understanding and treatment of gender identity disorders. 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 gender identity disorders, but also provides information for professionals and consumers, sponsors scientific conferences and offers ethical guidelines for professionals.
In 2006, WPATH began implementing a name change from the Harry Benjamin International Gender Dysphoria Association (HBIGDA).
