Transsexual

Transsexual (also Transexual, occasionally Trans-Sexual) refers to an individual whose gender identity is in conflict with his or her sex at birth, and who often seeks Transition and/or Sex Reassignment Surgery to resolve the issue.

The double-S spelling is attributed to Harry Benjamin.

The term has various explicit as well as imprecise clinical definitions appearing in various publications. The Diagnostic and Statistical Manual of the American Psychiatric Association uses the term Gender Dysphoria, a term previously considered anachronistic, to denote the condition previously known as Gender Identity Disorder and sometimes referred to as Transsexuality.
