Public education The institute aimed to educate both the general public and specialists on its topics of focus. It became a point of scientific and research interest for many scientists of sexuality, as well as intellectuals and reformers from all over the world. One particular fixture at the institute which aided its popularity was its museum of sexual subjects. This was built with both education and entertainment in mind. There were ethnographic displays about different
sexual norms across different cultures internationally. It included exhibits about
sexual fetishism and
sadomasochism. A collection of
phallic artifacts from around the world was also exhibited. Additionally, there were presentations regarding the diversity of human
sexual orientation, particularly with regards to homosexuality. Upon visiting the institute,
Dora Russell reflected that it was "where the results of researches into various
sex problems and
perversions could be seen in records and photographs." The neighboring property purchased in 1922 by the institute had an opening ceremony on 5 March 1922, after which it became a place for the institute's staff to interact with the public in an educational capacity. Lectures and question-and-answer sessions were held there to inform laypersons on topics of sexuality. The public especially tended to ask questions regarding contraception.
Sexual and reproductive health One focus of the institute's research and services was
sexual and reproductive health. A subdivision of the institute called the Eugenics Department for Mother and Child offered
marital counseling services, and the Center of Sexual Counseling for Married Couples provided access to
contraception. It was especially a goal of the institute to make contraceptive services accessible to the poor and working-class of Germany. This was despite a prohibition on advertising birth control in the
Weimar Republic's constitution. Following looser regulation on advertising contraceptive methods, the institute published an educational pamphlet on the matter in 1928 which ultimately reached a distribution of about 100,000 copies by 1932. Hirschfeld and Hodann developed pioneering strategies for sex counseling services that would inspire later practices.
Transsexuality and transvestism Magnus Hirschfeld coined the term transsexual in the 1923 essay
Die Intersexuelle Konstitution. Other descriptions "in the modern medical sense" also appeared in earlier German medical literature, such as
Johann Baptist Friedreich's 1829–1830 work. Various endocrinologic and surgical services were offered, including an early modern
sex reassignment surgery in 1931.
Testosterone had never been synthesized until 1935 (after the institute closed), so
masculinizing hormone therapy was never available at the institute. Ludwig Levy-Lenz, the institute's primary surgeon for transsexual patients, also implemented an early form of
facial feminization surgery and
facial masculinization surgery. Additionally, hair removal treatments using the institute's
X-ray facility were developed, though this caused some side effects such as skin burns. Professor of history
Robert M. Beachy stated that, "Although experimental and, ultimately, dangerous, these sex-reassignment procedures were developed largely in response to the ardent requests of patients." Levy-Lenz commented, "[N]ever have I operated upon more grateful patients." Hirschfeld worked with Berlin's police department to curtail the arrest of cross-dressers 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.
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. 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 1924. Hirschfeld, who initially supported some of these experiments, questioned whether such practices were
medically ethical, and was concerned with the potential they could have for reducing the diversity of natural human phenomena. The experiments were in fact intended to demonstrate the
biological basis of homosexuality in the influence of
sex hormones. However, he sometimes also advocated strategic
sex assignment at birth, on a scientific basis. Photographs of intersex cases were among the collections at the institute – these were used as part of an effort to demonstrate sexual intermediacy to the average layperson. ==Nazi era==
