The terms gender dysphoria and gender identity disorder were not used until the 1970s, when Laub and Fisk published several works on transsexualism using these terms. "Transsexualism" was replaced in the DSM-IV by "gender identity disorder in adolescents and adults". Male-to-female transsexualism has sometimes been called "Harry Benjamins syndrome" after the endocrinologist who pioneered the study of dysphoria. As the present-day medical study of gender variance is much broader than Benjamins early description, there is greater understanding of its aspects, and use of the term Harry Benjamins syndrome has been criticized for delegitimizing gender-variant people with different experiences. Sexual orientation
Since the middle of the 20th century, homosexual transsexual and related terms were used to label individuals sexual orientation based on their birth sex. Many sources criticize this choice of wording as confusing, "heterosexist", "archaic", and demeaning because it labels people by sex assigned at birth instead of their gender identity. Sexologist John Bancroft also recently expressed regret for having used this terminology, which was standard when he used it, to refer to transsexual women. He says that he now tries to choose his words more sensitively. Sexologist Charles Allen Moser is likewise critical of the terminology. Sociomedical scientist Rebecca Jordan-Young challenges researchers like Simon LeVay, J. Michael Bailey, and Martin Lalumiere, who she says "have completely failed to appreciate the implications of alternative ways of framing sexual orientation. "The terms androphilia and gynephilia to describe a persons sexual orientation without reference to their gender identity were proposed and popularized by psychologist Ron Langevin in the 1980s.
If the subject of your news article uses the word transsexual to describe themself, use it as an adjective: transsexual woman or transsexual man. Terminological variance
The word transsexual is most often used as an adjective rather than a noun – a "transsexual person" rather than simply "a transsexual". As of 2018, use of the noun form (e.g. referring to people as transsexuals) is often deprecated by those in the transsexual community. Like other trans people, transsexual people prefer to be referred to by the gender pronouns and terms associated with their gender identity. For example, a trans man is a person who was assigned the female sex at birth on the basis of his genitals, but despite that assignment, identifies as a man and is transitioning or has transitioned to a male gender role; in the case of a transsexual man, he furthermore has or will have a masculine body. Transsexual people are sometimes referred to with directional terms, such as "female-to-male" for a transsexual man, abbreviated to "F2M", "FTM", and "F to M", or "male-to-female" for a transsexual woman, abbreviated "M2F", "MTF" and "M to F". Individuals who have undergone and completed sex reassignment surgery are sometimes referred to as transsexed individuals; however, the term transsexed is not to be confused with the term transsexual, which can also refer to individuals who have not yet undergone SRS, and whose anatomical sex (still) does not match their psychological sense of personal gender identity.
