Testosterone poisoning is a popular term used to explain behaviors that are deemed excessively masculine. [1] It is also used by transfeminine people including transgender women and nonbinary individuals to describe the negative effects that testosterone has had on their bodies.
An early printed reference to "testosterone poisoning" came in 1975 from actor Alan Alda. In a parody of self-help writing, Alda diagnosed the "ailment" of masculinity and offered methods for its "cure". [2] He wrote:
Everyone knows that testosterone, the so-called male hormone, is found in both men and women. What is not so well known, is that men have an overdose... Until recently it has been thought that the level of testosterone in men is normal simply because they have it. But if you consider how abnormal their behavior is, then you are led to the hypothesis that almost all men are suffering from testosterone poisoning. [3]
Ten years later, that same sentence from Alda's article was quoted in the 1985 book A Feminist Dictionary. [4]
Carl Sagan gave the phrase more publicity when he praised Moondance magazine writer Daniela Gioseffi's American Book Award winner Women on War as follows: "A book of searing analysis and cries from the heart on the madness of war. Why is the half of humanity with a special sensitivity to the preciousness of life, the half untainted by testosterone poisoning, almost wholly unrepresented in defense establishments and peace negotiations worldwide?" [5] A Los Angeles Times op-ed piece accused Sagan of "pompously inform[ing] us that the whole planet is imminently endangered by 'testosterone poisoning'". [6]
Bruce Tremper used the term in The Avalanche Review, stating that being "a man" is best proven by dying "a stupendously violent death". [7] [ better source needed ]
A 1996 Psychology Today article referred to the phrase as "only a joke", but noted that a study about testosterone and male employment had shown that testosterone levels were lower for successful new male employees at a southern U.S. oil firm than they were for new male employees who had quit their jobs or been terminated. [8]
Berenbaum et al. (1997) stated that exposure to high levels of androgens in utero is associated with higher levels of adult aggression. [9] [10] Mazur et al. (1998) stated that males with higher testosterone levels tend to be slightly more aggressive than other males. The authors suggested that higher testosterone levels were a result of aggressive behavior, not a cause of it. [11]
In Family and Friends' Guide to Domestic Violence, Elaine Weiss wrote that "deadly testosterone poisoning" (DTP) is one of "many misunderstandings about abusive men". She continued: "[This] is not a war of the hormones, an inevitable biological clash between estrogen and testosterone. If it were, then there would be more of it; every heterosexual relationship would be abusive". [12]
McDermott (2007) found a significant positive relationship between levels of testosterone and aggression. [13] However, the link between testosterone and aggression was questioned in a 2010 study published in Nature. According to that study, "a single dose of testosterone in women causes a substantial increase in fair bargaining behaviour, thereby reducing bargaining conflicts and increasing the efficiency of social interactions. However, subjects who believed that they received testosterone—regardless of whether they actually received it or not—behaved much more unfairly than those who believed that they were treated with placebo." [14]
Antonia Feitz protested the use of the expression in a 1999 essay in the Australian Daily Issues Paper, calling it hate speech. [15]
Beth Gallagher's Salon.com essay "Road Sows", which discussed sports utility vehicles, asserted that "Not long ago, if you found yourself being tailed within an inch of your life by one of these monsters, you could be reasonably sure that testosterone poisoning was at work. But now I don't even bother to check my makeup — the macho creep back there is as likely to be the soccer mom next door, or even her mom..." [16] Several readers submitted "testosterone poisoning" to a 2001 Atlantic Monthly competition to find a male equivalent for hysteria (which was originally regarded as a female-only condition). [17] Dr. Karl Albrecht made testosterone poisoning a synonym for male chauvinism in his 2002 book The Power of Minds at Work: Organizational Intelligence in Action; he described the phenomenon as one of 17 basic syndromes of dysfunction. [18]
In a 2003 Wall Street Journal essay, Kay S. Hymowitz chided Western feminists for neglecting the rights of Third World women in Muslim countries; she wrote: "There is no need, in their minds, to distinguish between Osama, Saddam, and Bush: They're all suffering from testosterone poisoning". [19]
Magazine editor Tina Brown used the phrase thematically in a 2005 Washington Post essay about the downfall of Harvard University president Larry Summers and the problems of Disney's former embattled CEO Michael Eisner. [20]
The term is also sometimes used in a humorous context by transfeminine people, including transgender women, to describe how testosterone has damaged their bodies [21] . Masculine secondary sex characteristics such as facial hair, muscle growth, and a deepened voice are often jokingly referred to as symptoms of testosterone poisoning in transgender contexts. [22] While this usage of the term is far less common than the original, it also uses humor to criticize the effects of testosterone on the body.
Testosterone is the primary male sex hormone and androgen in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. It is associated with increased aggression, sex drive, dominance, courtship display, and a wide range of behavioral characteristics. In addition, testosterone in both sexes is involved in health and well-being, where it has a significant effect on overall mood, cognition, social and sexual behavior, metabolism and energy output, the cardiovascular system, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty, accumulation of adipose fat tissue within the body, anxiety and depression, sexual performance issues, and bone loss.
Aggression is a behavior aimed at opposing or attacking something or someone. Though often done with the intent to cause harm, it can be channeled into creative and practical outlets for some. It may occur either reactively or without provocation. In humans, aggression can be caused by various triggers. For example, built-up frustration due to blocked goals or perceived disrespect. Human aggression can be classified into direct and indirect aggression; while the former is characterized by physical or verbal behavior intended to cause harm to someone, the latter is characterized by behavior intended to harm the social relations of an individual or group.
Transphobia consists of negative attitudes, feelings, or actions towards transgender people or transness in general. Transphobia can include fear, aversion, hatred, violence or anger towards people who do not conform to social gender roles. Transphobia is a type of prejudice and discrimination, similar to racism, sexism, or ableism, and it is closely associated with homophobia. People of color who are transgender experience discrimination above and beyond that which can be explained as a simple combination of transphobia and racism.
An androgen is any natural or synthetic steroid hormone that regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors. This includes the embryological development of the primary male sex organs, and the development of male secondary sex characteristics at puberty. Androgens are synthesized in the testes, the ovaries, and the adrenal glands.
Sex differences in psychology are differences in the mental functions and behaviors of the sexes and are due to a complex interplay of biological, developmental, and cultural factors. Differences have been found in a variety of fields such as mental health, cognitive abilities, personality, emotion, sexuality, friendship, and tendency towards aggression. Such variation may be innate, learned, or both. Modern research attempts to distinguish between these causes and to analyze any ethical concerns raised. Since behavior is a result of interactions between nature and nurture, researchers are interested in investigating how biology and environment interact to produce such differences, although this is often not possible.
Sex differences in crime are differences between men and women as the perpetrators or victims of crime. Such studies may belong to fields such as criminology, sociobiology, or feminist studies. Despite the difficulty of interpreting them, crime statistics may provide a way to investigate such a relationship from a gender differences perspective. An observable difference in crime rates between men and women might be due to social and cultural factors, crimes going unreported, or to biological factors. The nature or motive of the crime itself may also require consideration as a factor. Gendered profiling might affect the reported crime rates.
Testosterone cypionate, sold under the brand name Depo-Testosterone among others, is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels in men, including hormone therapy for transgender men. It is given by injection into muscle or subcutaneously, once every one to four weeks, depending on clinical indication.
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.
Masculinizing hormone therapy, also known as transmasculine hormone therapy, is a form of hormone therapy and gender affirming therapy which is used to change the secondary sexual characteristics of transgender people from feminine or androgynous to masculine. It is a common type of transgender hormone therapy, and is predominantly used to treat transgender men and other transmasculine individuals who were assigned female at birth. Some intersex people also receive this form of therapy, either starting in childhood to confirm the assigned sex or later if the assignment proves to be incorrect.
Feminizing hormone therapy, also known as transfeminine hormone therapy, is hormone therapy and sex reassignment therapy to change the secondary sex characteristics of transgender people from masculine or androgynous to feminine. It is a common type of transgender hormone therapy and is used to treat transgender women and non-binary transfeminine individuals. Some, in particular intersex people, but also some non-transgender people, take this form of therapy according to their personal needs and preferences.
Alcohol and sex deals with the effects of the consumption of alcohol on sexual behavior. The effects of alcohol are balanced between its suppressive effects on sexual physiology, which will decrease sexual activity, and its suppression of sexual inhibitions. A large portion of sexual assaults involve alcohol consumption by the perpetrator, victim, or both.
The challenge hypothesis outlines the dynamic relationship between testosterone and aggression in mating contexts. It proposes that testosterone promotes aggression when it would be beneficial for reproduction, such as mate guarding, or strategies designed to prevent the encroachment of intrasexual rivals. The positive correlation between reproductive aggression and testosterone levels is seen to be strongest during times of social instability. The challenge hypothesis predicts that seasonal patterns in testosterone levels are a function of mating system, paternal care, and male-male aggression in seasonal breeders.
Transmisogyny, otherwise known as trans-misogyny and transphobic misogyny, is the intersection of transphobia and misogyny as experienced by trans women and transfeminine people. The term was coined by Julia Serano in her 2007 book Whipping Girl to describe a particular form of oppression experienced by trans women. In a 2017 interview with The New York Times, Serano explores the roots of transmisogyny as a critique of feminine gender expressions which are "ridiculed in comparison to masculine interests and gender expression."
Sexual motivation is influenced by hormones such as testosterone, estrogen, progesterone, oxytocin, and vasopressin. In most mammalian species, sex hormones control the ability and motivation to engage in sexual behaviours.
Transgender pregnancy is the gestation of one or more embryos or fetuses by transgender people. As of 2024, the possibility is restricted to those born with female reproductive systems. However, transition-related treatments may impact fertility. Transgender men and nonbinary people who are or wish to become pregnant face social, medical, legal, and psychological concerns. As uterus transplantations are currently experimental, and none have successfully been performed on trans women, they cannot become pregnant.
Female intrasexual competition is competition between women over a potential mate. Such competition might include self-promotion, derogation of other women, and direct and indirect aggression toward other women. Factors that influence female intrasexual competition include the genetic quality of available mates, hormone levels, and interpersonal dynamics.
Testosterone (T) is a medication and naturally occurring steroid hormone. It is used to treat male hypogonadism, gender dysphoria, and certain types of breast cancer. It may also be used to increase athletic ability in the form of doping. It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful. Testosterone can be used as a gel or transdermal patch that is applied to the skin topically, intramuscular injection (IM), buccally, or as an oral tablet.
The medical uses of bicalutamide, a nonsteroidal antiandrogen (NSAA), include the treatment of androgen-dependent conditions and hormone therapy to block the effects of androgens. Indications for bicalutamide include the treatment of prostate cancer in men, skin and hair conditions such as acne, seborrhea, hirsutism, and pattern hair loss in women, high testosterone levels in women, hormone therapy in transgender women, as a puberty blocker to prevent puberty in transgender girls and to treat early puberty in boys, and the treatment of long-lasting erections in men. It may also have some value in the treatment of paraphilias and hypersexuality in men.
The evolutionary neuroandrogenic (ENA) theory is a conceptual framework which seeks to explain trends in violent and criminal behavior from an evolutionary and biological perspective. It was first proposed by the sociologist Lee Ellis in 2005 in his paper "A Theory Explaining Biological Correlates of Criminality" published in the European Journal of Criminology. Since then, it has expanded into an interdisciplinary field that intersects biology, psychology, and sociology. The theory rests on two propositions. The first is that in human mating behavior, females prefer males that appear to be more competent providers of resources, and so males exhibit increased competitive behavior than females to obtain access to those resources. The second is that biological mechanisms lead to differential development in the male brain which then mediates the increased competitive behaviors that cause criminality. Though it was originally intended to explain high rates of criminality in young men, it has since been used as a framework to explain gang behavior, terrorism, and the rise of the criminal justice system.
Discrimination against transgender men and transmasculine individuals is sometimes referred to as transandrophobia, anti-transmasculinity, or transmisandry.
It is the shadow side of the extreme feminist movement, an ideology of hate whose name is not yet found in the dictionary. I term it misandrosy (Greek: "hatred of men"), the mirror opposite of misogyny. Misandrosy, not yet as widespread or harmful as misogyny but not yet as well recognized, either, is beginning to show itself mainly in liberal circles in the arts, literature, religion, media and academia. [...] Carl Sagan even pompously informs us that the whole planet is imminently endangered by "testosterone poisoning".
