Sex Reassignment Therapy

Sex reassignment therapy (SRT) is an umbrella term for all medical procedures regarding sex reassignment of both transgender and intersexual people. Sometimes SRT is also called gender reassignment, although it is a misnomer as SRT alters physical sexual characteristics to more accurately reflect the individual's psychological/social gender identity, rather than vice versa as is implied by the term "gender reassignment." Most trans people simply call this process transition.

Sex reassignment therapy can consist of hormone replacement therapy (HRT) to modify secondary sex characteristics, sex reassignment surgery to alter primary sex characteristics, and permanent hair removal for trans women.

In addition to undergoing medical procedures, transsexual people who go through sex reassignment therapy usually change their social gender roles, legal names and legal sex designation. The entire process of change from one gender presentation to another is known as transition.
