John Money is famous for his involvement in a case of malpractice related to a botched circumcision, for which he advocated that the boy with the butchered penis be raised as a girl, under his long term supervision which involved the ongoing sexual abuse and exploitation of the boy with the mutilated genitalia and his twin brother. The former committed suicide after telling Oprah his story. His brother died of a drug overdose.
