roots for gender dysphoria. In a September 2022 review of gender exploratory therapy, bioethicist Florence Ashley found strong similarities to conversion practices. Motivations A frequent motivation for adults who pursue conversion therapy is their religious beliefs, especially evangelical Christianity and Orthodox Judaism, that disapprove of same-sex relations. These adults prioritize maintaining a good relationship with their family and religious community. Adolescents who are pressured by their families into undergoing conversion therapy also typically come from a conservative religious background. Youth from families with low socioeconomic status are also more likely to undergo conversion therapy. Theories and techniques As societal attitudes toward homosexuality have become more tolerant over time, the most harsh conversion therapy methods such as aversion have been reduced. Secular conversion therapy is offered less often due to reduced medical pathologization of homosexuality, and religious practitioners have become more dominant. Aversion therapy Aversion therapy used on homosexuals included electric shock and nausea-inducing drugs during presentation of same-sex erotic images. Cessation of the aversive stimuli was typically accompanied by the presentation of opposite-sex erotic images, with the objective of strengthening heterosexual feelings. Another method used was the covert sensitization method, which involves instructing patients to imagine vomiting or receiving electric shocks, writing that only single case studies have been conducted, and that their results cannot be generalized. Haldeman writes that behavioral conditioning studies tend to decrease homosexual feelings, but do not increase heterosexual feelings, citing Rangaswami's "Difficulties in arousing and increasing heterosexual responsiveness in a homosexual: A case report", published in 1982, as typical in this respect. Aversion therapy was developed in Czechoslovakia between 1950 and 1962 and in the Commonwealth from 1961 into the mid-1970s. In the context of the Cold War, Western psychologists ignored the poor results of their Czechoslovak counterparts, who had concluded that aversion therapy was not effective by 1961 and recommended decriminalization of homosexuality instead. Some men in the United Kingdom were offered the choice between prison and undergoing aversion therapy. It was also offered to a few British women, but was never the standard treatment for either homosexual men or women. Brain surgery In the 1940s and 1950s, U.S. neurologist Walter Freeman popularized the ice-pick lobotomy as a treatment for homosexuality. He personally performed as many as 3,439 lobotomy surgeries in 23 states, of which 2,500 used his ice-pick procedure, despite the fact that he had no formal surgical training.
