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, colloquially,
a sex change) is the
surgical procedure (or procedures) by which a
transgender person's physical appearance and function of their existing
sexual characteristics are altered to resemble that of their identified
gender. It is part of a treatment for
gender dysphoria in 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.
