Conversion therapy is the pseudoscientific practice of attempting to change an individual's sexual orientation, gender identity, or gender expression to align with heterosexual and cisgender norms. Methods that have been used to this end include forms of brain surgery, surgical or hormonal castration, aversive treatments such as electric shocks, nausea-inducing drugs, hypnosis, counseling, spiritual interventions, visualization, psychoanalysis, and arousal reconditioning.
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.
Perversion is a form of human behavior which deviates from what is considered to be orthodox or normal. Although the term perversion can refer to a variety of forms of deviation, it is most often used to describe sexual behaviors that are considered particularly abnormal, repulsive or obsessive. Perversion differs from deviant behavior, in that the latter covers areas of behavior for which perversion would be too strong a term. It is often considered derogatory, and, in psychological literature, the term paraphilia has been used as a replacement, though this term is controversial, and deviation is sometimes used in its place.
Harry Benjamin was a German-American endocrinologist and sexologist, widely known for his clinical work with transgender people.
The World Professional Association for Transgender Health (WPATH), formerly the Harry Benjamin International Gender Dysphoria Association (HBIGDA), is a professional organization devoted to the understanding and treatment of gender identity and gender dysphoria, and creating standardized treatment for transgender and gender variant people. WPATH was founded in September 1979 by endocrinologist and sexologist Harry Benjamin, with the goal of creating an international community of professionals specializing in treating gender variance.
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.
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.
Transgender rights in Iran are limited, with a narrow degree of official recognition of transgender identities by the government, but with trans individuals facing very high levels of discrimination, from the law, the state, and from the wider society.
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.
The 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. 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.
While in ordinary speech, the terms sex and gender are often used interchangeably, in contemporary academic literature, the terms often have distinct meanings, especially when referring to people. Sex generally refers to an organism's biological sex, while gender usually refers to either social roles typically associated with the sex of a person or personal identification of one's own gender based on an internal awareness. Most contemporary social scientists, behavioral scientists and biologists, many legal systems and government bodies, and intergovernmental agencies such as the WHO make a distinction between gender and sex.
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.
Kenneth J. Zucker is an American-Canadian psychologist and sexologist. He was named editor-in-chief of Archives of Sexual Behavior in 2001. He was psychologist-in-chief at Toronto's Centre for Addiction and Mental Health (CAMH) and head of its Gender Identity Service until December 2015. Zucker is a professor in the departments of psychiatry and psychology at the University of Toronto.
A transgender person is someone whose gender identity differs from that typically associated with the sex they were assigned at birth. Some transgender people who desire medical assistance to transition from one sex to another identify as transsexual. Transgender is also an umbrella term; in addition to including people whose gender identity is the opposite of their assigned sex, it may also include people who are non-binary or genderqueer. Other definitions of transgender also include people who belong to a third gender, or else conceptualize transgender people as a third gender. The term may also include cross-dressers or drag kings and drag queens in some contexts. The term transgender does not have a universally accepted definition, including among researchers.
A transsexual person is someone who experiences a gender identity that is inconsistent with their assigned sex, and desires 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.
Anne Alexandra Lawrence is an American psychologist, sexologist, and physician who has published extensively on gender dysphoria, transgender people, and paraphilias. Lawrence is a transgender woman and self-identifies as autogynephilic. She is best known for her 2013 book on autogynephilia, Men Trapped in Men's Bodies: Narratives of Autogynephilic Transsexualism, which has been regarded by Ray Blanchard as the definitive text on the subject. Lawrence is one of the major researchers in the area of Blanchard's etiological typology of transgender women and has been one of the most major proponents of the theory. While Blanchard's typology and autogynephilia are highly controversial subjects and are not accepted by many transgender women and academics, some, such as Lawrence, identify with autogynephilia. Lawrence's work also extends beyond Blanchard's typology, to transgender women and to transition more generally.
Agnes is the pseudonym given to a transgender woman who participated in Harold Garfinkel's research in the early 1960s, making her the first subject of an in-depth discussion of transgender identity in sociology. She is the subject of a 2018 documentary short and a 2022 documentary, both titled Framing Agnes.
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.
