Gender identity is the personal sense of one's own gender. Gender identity can correlate with a person's assigned sex or can differ from it. In most individuals, the various biological determinants of sex are congruent, and consistent with the individual's gender identity. Gender expression typically reflects a person's gender identity, but this is not always the case. While a person may express behaviors, attitudes, and appearances consistent with a particular gender role, such expression may not necessarily reflect their gender identity. The term gender identity was coined by psychiatry professor Robert J. Stoller in 1964 and popularized by the controversial psychologist John Money.
John William Money was a New Zealand American psychologist, sexologist and professor at Johns Hopkins University known for his research on human sexual behavior and gender. Believing that gender identity was malleable within the first two years of life, Money advocated for the surgical "normalization" of the genitalia of intersex infants.
The following outline is provided as an overview of and topical guide to transgender topics.
John Michael Bailey is an American psychologist, behavioral geneticist, and professor at Northwestern University best known for his work on the etiology of sexual orientation and paraphilia. He maintains that male sexual orientation is most likely established in utero.
Richard Green was an American-British sexologist, psychiatrist, lawyer, and author known for his research on homosexuality and transsexualism, specifically gender identity disorder in children. He is known for his behaviorism experiment in which he attempted to prevent male homosexuality and transsexuality by extinguishing feminine behavior in young boys. He later came to favor biological explanations for male homosexuality.
The Man Who Would Be Queen: The Science of Gender-Bending and Transsexualism is a 2003 book by the American psychologist J. Michael Bailey, published by Joseph Henry Press.
Androphilia and gynephilia are terms used in behavioral science to describe sexual orientation, as an alternative to a gender binary homosexual and heterosexual conceptualization. Androphilia describes sexual attraction to men and/or masculinity; gynephilia describes the sexual attraction to women and/or femininity. Ambiphilia describes the combination of both androphilia and gynephilia in a given individual, or bisexuality.
Ray Milton Blanchard is an American-Canadian sexologist who researches pedophilia, sexual orientation and gender identity. He has found that men with more older brothers are more likely to be gay than men with fewer older brothers, a phenomenon he attributes to the reaction of the mother's immune system to male fetuses. Blanchard has also published research studies on phallometry and several paraphilias, including autoerotic asphyxia. Blanchard also proposed a typology of transsexualism.
American-Canadian sexologist Ray Blanchard proposed a psychological typology of gender dysphoria, transsexualism, and fetishistic transvestism in a series of academic papers through the 1980s and 1990s. Building on the work of earlier researchers, including his colleague Kurt Freund, Blanchard categorized trans women into two groups: homosexual transsexuals who are attracted exclusively to men and are feminine in both behavior and appearance; and autogynephilic transsexuals who experience sexual arousal at the idea of having a female body (autogynephilia). Blanchard and his supporters argue that the typology explains differences between the two groups in childhood gender nonconformity, sexual orientation, history of sexual fetishism, and age of transition.
Gender incongruence is the state of having a gender identity that does not correspond to one's sex assigned at birth. This is experienced by people who identify as transgender or transsexual, and often results in gender dysphoria. The causes of gender incongruence have been studied for decades.
Sexuality in transgender individuals encompasses all the issues of sexuality of other groups, including establishing a sexual identity, learning to deal with one's sexual needs, and finding a partner, but may be complicated by issues of gender dysphoria, side effects of surgery, physiological and emotional effects of hormone replacement therapy, psychological aspects of expressing sexuality after medical transition, or social aspects of expressing their gender.
The classification of transsexual and gender non-conforming people into distinct groups has been attempted since the mid-1960s.
David Oliver Cauldwell was a prolific and pioneering sexologist, who coined the term transsexual as used in its current definition. Many of his monographs on sex, psychology, or health were published by Emanuel Haldeman-Julius in such forms as Big Blue Books. He was the editor of Sexology magazine's question and answer department. Cauldwell and Harry Benjamin were "two early and important American voices on transsexuality".
Ira Basil Pauly is an American psychiatrist who was an All American college football player at UCLA, and is known for his influential work on transsexualism.
Transsexual people experience a gender identity that is inconsistent with their assigned sex, and desire to permanently transition to the sex or gender with which they identify, usually seeking medical assistance to help them align their body with their identified sex or gender.
Erotic target location error (ETLE) is a hypothesized dimension for paraphilias, defined by having a sexual preference or strong sexual interest in features that are somewhere other than on one's sexual partners. When one's sexual arousal is based on imagining oneself in another physical form (such as an animal, an infant, or an amputee) the erotic target is said to be one's self, or erotic target identity inversion (ETII).
Anne Alexandra Lawrence is an American psychologist, sexologist, and former anesthesiologist who has published extensively on gender incongruence. Anne transitioned male to female in her 40s.
"The Empire Strikes Back: A Posttranssexual Manifesto" is a 1987 essay written by Sandy Stone. Stone's essay is considered to be the founding text of transgender studies in academia, with other critical transgender works emerging after it. The essay examines how transgender women have historically been viewed, studied, and treated by the western medical establishment.
The Transsexual Phenomenon is a medical textbook published by American endocrinologist and sexologist Harry Benjamin in 1966 with The Julian Press. The text is notable for its examination of transsexualism not as a psychological issue, but rather as a somatic disorder that should be treated through medicine. Benjamin argues that transvestism and transsexuality are a spectrum of conditions, requiring different treatments that ranged from hormone replacement therapy to surgical intervention.
Transsexualism and Sex Reassignment is a book on gender dysphoria which was edited by sexologists Richard Green and John Money and was published by Johns Hopkins University Press in 1969. It was the first medical textbook to be published on transgender people. The book contained a chapter on hormone replacement therapy written by Christian Hamburger and included an appendix with additional treatment suggestions and guidelines by Harry Benjamin.
