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.
Sexology is the scientific study of human sexuality, including human sexual interests, behaviors, and functions. The term sexology does not generally refer to the non-scientific study of sexuality, such as social criticism.
The field of psychology has extensively studied homosexuality as a human sexual orientation. The American Psychiatric Association listed homosexuality in the DSM-I in 1952, but that classification came under scrutiny in research funded by the National Institute of Mental Health. That research and subsequent studies consistently failed to produce any empirical or scientific basis for regarding homosexuality as anything other than a natural and normal sexual orientation that is a healthy and positive expression of human sexuality. As a result of this scientific research, the American Psychiatric Association removed homosexuality from the DSM-II in 1973. Upon a thorough review of the scientific data, the American Psychological Association followed in 1975 and also called on all mental health professionals to take the lead in "removing the stigma of mental illness that has long been associated" with homosexuality. In 1993, the National Association of Social Workers adopted the same position as the American Psychiatric Association and the American Psychological Association, in recognition of scientific evidence. The World Health Organization, which listed homosexuality in the ICD-9 in 1977, removed homosexuality from the ICD-10 which was endorsed by the 43rd World Health Assembly on 17 May 1990.
Men who have sex with men (MSM) refers to all men who engage in sexual activity with other men, regardless of their sexual orientation or sexual identity. The term was created by epidemiologists in the 1990s, to better study and communicate the spread of sexually transmitted infections such as HIV/AIDS between all sexually active males, not strictly those identifying as gay, bisexual, pansexual or various other sexualities, but also for example male prostitutes. The term is often used in medical literature and social research to describe such men as a group. It does not describe any specific kind of sexual activity, and which activities are covered by the term depends on context. An alternative term, males who have sex with males is sometimes considered more accurate in cases where those described may not be legal adults.
The Institut für Sexualwissenschaft was an early private sexology research institute in Germany from 1919 to 1933. The name is variously translated as Institute for Sexual Research, Institute of Sexology, Institute for Sexology, or Institute for the Science of Sexuality. The Institute was a non-profit foundation situated in Tiergarten, Berlin. It was the first sexology research center in the world.
Comprehensive Sexuality Education (CSE) is a sex education instruction method based on a curriculum that aims to give students the holistic knowledge, attitudes, skills, and values to make healthy and informed choices in their sexual lives. The intention is that this understanding will help students understand their body and reproductive processes, engage in safer sex by reduce incidents of contracting sexually transmitted infections (STIs) such as HIV and HPV, reduce unplanned and unwanted pregnancies, as well as lowering rates of domestic and sexual violence.
Women who have sex with women (WSW) are women who engage in sexual activities with women, whether they identify as straight, lesbian, bisexual, pansexual, have other sexualities, or dispense with sexual identification altogether. The term WSW is often used in medical literature to describe such women as a group for clinical study, without needing to consider sexual self-identity.
Human sexuality covers a broad range of topics, including the physiological, psychological, social, cultural, political, philosophical, ethical, moral, theological, legal and spiritual or religious aspects of sex and human sexual behavior.
Timeline of events related to sexual orientation and medicine
Various issues in medicine relate to lesbian, gay, bisexual, and transgender people. According to the US Gay and Lesbian Medical Association (GLMA), besides HIV/AIDS, issues related to LGBT health include breast and cervical cancer, hepatitis, mental health, substance use disorders, alcohol use, tobacco use, depression, access to care for transgender persons, issues surrounding marriage and family recognition, conversion therapy, refusal clause legislation, and laws that are intended to "immunize health care professionals from liability for discriminating against persons of whom they disapprove."
Sandra Risa Leiblum (1943–2010) was an American author, lecturer, and researcher in sexology.
The Institute for Advanced Study of Human Sexuality (IASHS) was a private, unaccredited, for-profit graduate school and resource center for the field of sexology in San Francisco, California. It was established in 1976 and closed in 2018. Degree and certificate programs focused on public health, sex therapy, and sexological research.
HIV prevention refers to practices that aim to prevent the spread of the human immunodeficiency virus (HIV). HIV prevention practices may be undertaken by individuals to protect their own health and the health of those in their community, or may be instituted by governments and community-based organizations as public health policies.
The following outline is provided as an overview of and topical guide to human sexuality:
Since reports of emergence and spread of the human immunodeficiency virus (HIV) in the United States between the 1970s and 1980s, the HIV/AIDS epidemic has frequently been linked to gay, bisexual, and other men who have sex with men (MSM) by epidemiologists and medical professionals. It was first noticed after doctors discovered clusters of Kaposi's sarcoma and pneumocystis pneumonia in homosexual men in Los Angeles, New York City, and San Francisco in 1981. The first official report on the virus was published by the Center for Disease Control (CDC) on June 5, 1981, and detailed the cases of five young gay men who were hospitalized with serious infections. A month later, The New York Times reported that 41 homosexuals had been diagnosed with Kaposi's sarcoma, and eight had died less than 24 months after the diagnosis was made.
Jeffrey T. Parsons is an American psychologist, researcher, and educator; he was a Distinguished Professor of Psychology at Hunter College and The Graduate Center of the City University of New York (CUNY) and was the Director of Hunter College's Center for HIV/AIDS Educational Studies & Training, which he founded in 1996. Parsons was trained as a developmental psychologist and applied this training to understand health, with a particular emphasis on HIV prevention and treatment. He was known for his research on HIV risk behaviors of gay, bisexual, and other men who have sex with men (GBMSM), HIV-related syndemics, and sexual compulsivity. He resigned his positions at CUNY on July 3, 2019, following a year-long university investigation of misconduct allegations against him. In 2023, the U.S. Attorney's Office announced that he was required to pay a $375,000 settlement for engaging in fraud against the federal government for many years.
Brian Mustanski is an American psychologist noted for his research on the health of LGBT youth, HIV and substance use in young gay and bisexual men, and the use of new media and technology for sexual health promotion and HIV prevention. He is a Professor of Medical Social Sciences, Psychiatry and Behavioral Sciences, and Psychology and Director of the Institute for Sexual and Gender Minority Health and Wellbeing at Northwestern University, Chicago, Illinois.
The health access and health vulnerabilities experienced by the lesbian, gay, bisexual, transgender, queer or questioning, intersex, asexual (LGBTQIA) community in South Korea are influenced by the state's continuous failure to pass anti-discrimination laws that prohibit discrimination based on sexual orientation and gender identity. The construction and reinforcement of the South Korean national subject, "kungmin," and the basis of Confucianism and Christian churches perpetuates heteronormativity, homophobia, discrimination, and harassment towards the LGBTQI community. The minority stress model can be used to explain the consequences of daily social stressors, like prejudice and discrimination, that sexual minorities face that result in a hostile social environment. Exposure to a hostile environment can lead to health disparities within the LGBTQI community, like higher rates of depression, suicide, suicide ideation, and health risk behavior. Korean public opinion and acceptance of the LGBTQI community have improved over the past two decades, but change has been slow, considering the increased opposition from Christian activist groups. In South Korea, obstacles to LGBTQI healthcare are characterized by discrimination, a lack of medical professionals and medical facilities trained to care for LGBTQI individuals, a lack of legal protection and regulation from governmental entities, and the lack of medical care coverage to provide for the health care needs of LGBTQI individuals. The presence of Korean LGBTQI organizations is a response to the lack of access to healthcare and human rights protection in South Korea. It is also important to note that research that focuses on Korean LGBTQI health access and vulnerabilities is limited in quantity and quality as pushback from the public and government continues.
The medicalisation of sexuality is the existence and growth of medical authority over sexual experiences and sensations. The medicalisation of sexuality is contributed to by the pharmaceutical industry, along with psychiatry, psychology, and biomedical sciences more generally.
