The Doctor Who Turned Two Boys Into an Experiment

In 1965, in Winnipeg, Canada, a young couple named Ron and Janet Reimer took their seven-month-old twin sons in for a routine circumcision. A device malfunction during the procedure destroyed the penis of one twin, Bruce. His brother Brian was left untouched. What followed was not a private medical tragedy. It became one of the most consequential — and most falsified — experiments in the history of gender science, and it was overseen by a single man: Dr. John Money, a psychologist at Johns Hopkins Hospital who had built a career, and a theory, on the idea that gender identity could be shaped by upbringing alone.

A Theory Looking for a Body

Money was already a prominent voice on sex and gender when the Reimers came across him on a television program discussing sex-reassignment surgery. He proposed what he called the theory of gender neutrality: that a child’s sense of being male or female was primarily learned in early childhood, not fixed by biology. Bruce’s injury gave Money something he had never had — an identical twin control subject. He advised the Reimers to raise Bruce as a girl, renamed Brenda, with surgical and hormonal intervention to follow, while Brian grew up as the untouched baseline^[1].

For years, Money reported the case — anonymized in his academic writing as “John/Joan” — as proof of his theory: a resounding, uncomplicated success. Textbooks adopted it. It shaped clinical guidance for intersex infants for a generation.

What Actually Happened in Baltimore

The reality, which surfaced only when David (the name Brenda chose after rejecting the assigned identity as a teenager) told his own story publicly in the late 1990s, was very different. According to David’s account — later corroborated in journalist John Colapinto’s reporting and the 2004 BBC documentary Dr Money and the Boy with No Penis — Brenda showed no comfort in the assigned identity from early childhood onward, and Money’s annual follow-up visits at Johns Hopkins were, by David’s description, deeply distressing^[2][4].

Both journalistic accounts describe Money directing the twins, during these sessions, to examine one another’s bodies and rehearse sexualized positions he framed as therapeutic “sexual rehearsal play,” reportedly sometimes in front of colleagues. David described being verbally harsh with the children when they resisted, a manner starkly different from the warmth he showed their parents. The children were never told the true purpose of what they were being asked to do^[4].

The Paper That Undid a Legacy

The correction, when it came, wasn’t a tabloid exposé — it was a peer-reviewed journal article. In 1997, Dr. Milton Diamond and Dr. H. Keith Sigmundson published “Sex Reassignment at Birth: A Long-Term Review and Clinical Implications” in the Archives of Pediatrics & Adolescent Medicine. Sigmundson, a psychiatrist with British Columbia’s Ministry of Health, had tracked the real outcome: David had rejected the female identity by age fourteen, learned the truth of his infancy from his father, and transitioned back to living as a boy against Money’s continued public claims of success^[3]. The paper forced a reckoning across pediatric and psychiatric medicine about treating infants’ bodies as sites of experimentation before those children could ever consent.

His Own Recorded Views

Separately from the Reimer case, Money is on record — most notably in a 1991 interview published in the academic journal Paidika: The Journal of Paedophilia — expressing views that normalized adult-child sexual contact, framing certain age-discrepant relationships as potentially non-harmful if “mutual.” Those remarks have been reported and re-reported by outlets across the ideological spectrum for decades; we were not able to independently verify a surviving full copy of the original interview, so we’re citing it here as a documented but secondhand-sourced part of his public record, not a verbatim transcript^[5].

Two Lives, Cut Short

Brian Reimer, diagnosed with schizophrenia in adulthood, died of an overdose in 2002. David Reimer took his own life in 2004, four years after going public and two years after his brother’s death^[4]. He was 38.

There is no version of this story that isn’t about power — a doctor’s power to decide what a child’s body and identity should be, exercised on two boys too young to say no, and defended in print long after the people living inside it were begging to be heard. That is the part of the record worth keeping intact.
