David Reimer (born Bruce Peter Reimer; 22 August 1965 – 4 May 2004) was a Canadian boy raised as a girl following medical advice and intervention after his penis was severely injured during a botched circumcision in infancy.

The psychologist John Money oversaw the case and incorrectly reported the reassignment as successful and as evidence that gender identity is primarily learned. The academic sexologist Milton Diamond later reported that Reimer's realization that he was not a girl occurred between the ages of 9 and 11 years and that he was living as a male by the age of 15. Well known in medical circles for years anonymously as the "John/Joan" case, Reimer later went public with his story to help discourage similar medical practices. He killed himself at age 38, two days after separating from his wife.

Life

Infancy

David Reimer was born in Winnipeg, Manitoba, on 22 August 1965, the elder of identical twin boys. He was originally named Bruce, and his identical twin was named Brian. Their parents were Janet and Ron Reimer, a couple of Mennonite descent who had married in December 1964. At the age of six months, after concern was raised about how both of them urinated, the boys were diagnosed with phimosis. They were referred for circumcision at the age of seven months. General practitioner Jean-Marie Huot performed the operation using the unconventional method of electrocauterization, but the procedure burned David's penis beyond surgical repair. The doctors did not operate on Brian, whose phimosis later cleared without surgical intervention.
