Intersex (Sex Determination & Change)

Sex reassignment surgery (initialized as SRS; also known as gender reassignment surgery (GRS), genital reconstruction surgery, sex affirmation surgery, gender confirmation surgery, sex realignment surgery or commonly known as sex change) is a term for the surgical procedures by which a person's physical appearance and function of their existing sexual characteristics are altered to resemble that of the other sex. It is part of a treatment for gender identity disorder/gender dysphoria in transsexual and transgender people. It may also be performed on intersex people, often in infancy and without their consent. A 2013 statement by the United Nations condemns the nonconsensual treatment of "normalization" surgery to treat intersexuality.

Other terms for SRS include sex reconstruction surgery, gender confirmation surgery, and more clinical terms, such as feminizing genitoplasty or penectomy , orchiectomy, and vaginoplasty, are used medically for trans women, with masculinizing genitoplasty, metoidioplasty or phalloplasty often similarly used for trans men.

People who pursue sex reassignment surgery are usually referred to as transsexual; "trans" - across, through, change; "sexual" - pertaining to the sexual characteristics (not sexual actions) of a person. More recently, people pursuing SRS often identify as transgender instead of transsexual.
