and transgender people, through the creation of transvestite passes. These were issued on behalf of the institute to those who had a personal desire to wear clothing associated with a gender other than the one assigned to them at birth. Homosexuality A compilation of works about homosexuality could be found at the institute. The institute's collections included the first comprehensive such compilation of works about sexuality. Different from the Others, a film co-written by Hirschfeld that advocated greater tolerance for homosexuals, was screened at the institute in 1920 to audiences of statesmen. It also received a screening at the institute before a Soviet delegation in 1923, who responded with "amazement" that the film had been considered scandalous enough to censor. Working off of the research of Eugen Steinach, who had recently succeeded in reversing the sexual behavior of animal test subjects, the institute once tested whether or not transplanting the testicles from a heterosexual man to a homosexual man would cure homosexuality. This method of "curing" homosexuality more often than not grew necrotized and resulted in the testicles having to be castrated. The practice was abandoned by the institute by 1924. Hirschfeld — who was homosexual himself — viewed homosexuality as natural and inborn, rather than an illness. The experiments were in fact intended to demonstrate the biological basis of homosexuality in the influence of sex hormones. The institute put adaption therapy into practice as a far more humane and effective method than conversion therapy, as a means of helping patients cope with their sexuality. Rather than attempting to cure a patient's homosexuality, the focus was instead placed on helping the patient learn to navigate a homophobic society with the least discomfort possible. While the doctors at the institute could not outright recommend illegal practices (and, at this time, most all homosexual acts were illegal in Germany), they also did not promote abstinence. They made an effort to help their gay patients find a sense of community, either with other patients, through the Scientific-Humanitarian Committee, or through a network of venues known to the institute that were aimed at gay men, lesbians, and cross-dressers. Additionally, the institute offered them general psychological and medical assistance. Intersexuality The institute presented expert reports about cases of intersex conditions. Hirschfeld is considered to have been a pioneer in this area of study. He advocated for the right of intersex individuals born with ambiguous genitalia
