his is the story of David Reimer. David was born “Bruce” – along with an identical twin brother, Brian. At 7 months of age, there was a circumcision accident in which “Bruce’s” penis was almost entirely burnt off. It was 1966, and the Reimer’s sought the best medical advice available.

Dr. John Money told the Reimer’s to raise their son as a daughter. He insisted that “she” never be told that “she” had been born male. The Reimer’s changed Bruce’s name to “Brenda” and raised her as a girl.

Money thought he had the perfect experiment to prove that gender was a product of environment, not our biology (genetics). He thought that gender was determined by nurture, not nature. He used the Reimer twins to prove his theory of “gender neutrality.”

What is the difference between sex, gender and sexual orientation?
David Reimer.

Based on this story, is gender the result of genetics or environment?

What do you make of the fact that “Brenda” was raised a girl and given female hormones (“she” was told they were vitamins), but grew up to marry a woman?

What does this suggest about the origins of sexual orientation?
