Gender identity is one's personal experience of one's own gender.[1] All societies have a set of gender categories that can serve as the basis of the formation of a person's social identity in relation to other members of society.[2] In most societies, there is a basic division between gender attributes assigned to males and females,[3] a gender binary to which most people adhere and which enforces conformance to ideals of masculinity and femininity in all aspects of sex and gender: biological sex, gender identity, and gender expression.[4] In all societies, some individuals do not identify with some (or all) of the aspects of gender that are assigned to their biological sex;[5] some of those individuals are transgender or genderqueer. Some societies have third gender categories.
Core gender identity is usually formed by age three.[6][7] After age three, it is extremely difficult to change,[6] and attempts to reassign it can result in gender dysphoria.[8] Both biological and social factors have been suggested to influence its formation.
Age of formation
There are several theories about how and when gender identity forms, and studying the subject is difficult because children's lack of language requires researchers to make assumptions from indirect evidence.[8] John Money suggested children might have awareness of, and attach some significance to gender, as early as 18 months to two years; Lawrence Kohlberg argues that gender identity does not form until age three.[8] It is widely agreed that core gender identity is firmly formed by age three.[6][7][8][9] At this point, children can make firm statements about their gender[8][10] and tend to choose activities and toys which are considered appropriate for their gender[8] (such as dolls and painting for girls, and tools and rough-housing for boys),[11] although they do not yet fully understand the implications of gender.[10] After age three, core gender identity is extremely difficult to change,[6][12] and attempts to reassign it can result in gender dysphoria.[8][13] Gender identity refinement extends into the fourth[12] to sixth years of age,[8][14] and continues into young adulthood.[12]
Martin and Ruble conceptualize this process of development as three stages: (1) as toddlers and preschoolers, children learn about defined characteristics, which are socialized aspects of gender; (2) around the ages of 5–7 years, identity is consolidated and becomes rigid; (3) after this "peak of rigidity," fluidity returns and socially defined gender roles relax somewhat.[15] Barbara Newmann breaks it down into four parts: (1) understanding the concept of gender, (2) learning gender role standards and stereotypes, (3) identifying with parents, and (4) forming gender preference.[10]
Factors influencing formation
Nature vs. nurture
Although the formation of gender identity is not completely understood, many factors have been suggested as influencing its development. In particular, the extent to which it is determined by socialization (environmental factors) versus innate (biological) factors is an ongoing debate in psychology, known as "nature versus nurture". Both factors are thought to play a role. Biological factors that influence gender identity include pre- and post-natal hormone levels.[16] While genetic makeup also influences gender identity,[17][18] it does not inflexibly determine it.[19]
Social factors which may influence gender identity include ideas regarding gender roles conveyed by family, authority figures, mass media, and other influential people in a child's life.[20] Language also plays a role: children, while learning a language, learn to separate masculine and feminine characteristics and unconsciously adjust their own behavior to these predetermined roles.[21] The social learning theory posits that children furthermore develop their gender identity through observing and imitating gender-linked behaviors, and then being rewarded or punished for behaving that way,[22] thus being shaped by the people surrounding them through trying to imitate and follow them.[23]
A well-known example in the nature verses nurture debate is the case of David Reimer, otherwise known as "John/Joan". As a baby, Reimer went through a faulty circumcision, losing his male genitalia. Psychologist John Money convinced Reimer’s parents to raise him as a girl. Reimer grew up as a girl, dressing in girl clothes and surrounded by girl toys, but did not feel like a girl. After he tried to commit suicide at age 13, he was told that he had been born with male genitalia, which he underwent surgery to reconstruct.[24] This went against Money’s hypothesis that biology had nothing to do with gender identity or human sexual orientation.[25]
Biological factors
Several prenatal, biological factors, including genes and hormones, may affect gender identity.[16][18][26] The biochemical theory of gender identity suggests that people acquire gender identities through such factors rather than socialization. A study by Reiner & Gearhart provides some insight into what can happen when genetically male children are sexually reassigned female and raised as girls: in a sample of 14 children born with cloacal exstrophy and reassigned female at birth, follow-up between the ages of 5 to 12 showed that 8 of them identified as boys, and all of the subjects had at least moderately male-typical attitudes and interests,[27] providing support for the argument that genetic variables have an impact on gender identity and behavior independent of socialization.
Genetic influences are more complex than XY chromosomes being male and XX being female:[28] translocation of Y chromosome material including the SRY gene to the X chromosome results in 46 XX individuals who have a masculine presentation with small nonfunctional testes, and who do not have a properly developed uterus or ovaries; in turn, the DAX1 gene may suppress development of testes and lead an XY embryo to develop as sexually female.[29][30] These conditions are referred to as intersex.
Hormonal influences are also complex; sex-determining hormones are produced at an early stage of fetal development,[31] and if prenatal hormone levels are altered, phenotype progression may be altered as well, and the natural predisposition of the brain toward one sex may not match the genetic make-up of the fetus or its external sexual organs.
Hormones may affect differences between males' and females' verbal and spatial abilities, memory, and aggression; prenatal hormone exposure affects how the hypothalamus regulates hormone secretion later in life, with "women's sex hormones usually follow[ing] a monthly cycle [while] men’s sex hormones do not follow such a pattern."[32]
Biological causes of transgender and transsexuality
Some studies have investigated whether or not there is a link between biological variables and transgender or transsexual identity.[33][34] Several studies have shown that sexually dimorphic brain structures in transsexuals are shifted away from what is associated with their birth sex and towards what is associated with their preferred sex.[35][36][37] In particular, the bed nucleus of a stria terminalis or BSTc (a constituent of the basal ganglia of the brain which is affected by prenatal androgens) of trans women is similar to cisgender women's and unlike men's.[38][39] Similar brain structure differences have been noted between gay and heterosexual men, and between lesbian and heterosexual women.[40][41] Another study suggests that transsexuality may have a genetic component.[42]
There is also evidence that prenatal exposure to endocrine-disrupting anti-miscarriage drugs such as diethylstilbestrol (DES) may also be positively associated with transsexualism, though research in this area has yet to establish a firm causal link.[43][44][45][46] Other research suggests that the same hormones that promote differentiation of sex organs in utero also elicit puberty and influence the development of gender identity. Different amounts of these male or female sex hormones within a person can result in behavior and external genitalia that do not match up with the norm of the actual sex, and in a person acting and looking like the opposite sex.[47]
Social and environmental factors
In 1955, John Money proposed that gender identity was malleable and determined by whether a child was raised as male or female in early childhood.[48][49] Money's hypothesis has since been discredited,[49][50] but scholars have continued to study the effect of social factors on gender identity formation.[49] In the 1960s and 1970s, factors such as the absence of a father, a mother's wish for a daughter, or parental reinforcement patterns were suggested as influences; more recent theories suggesting that parental psychopathology might partly influence gender identity formation have received only minimal empirical evidence,[49] with a 2004 article noting that "solid evidence for the importance of postnatal social factors is lacking."[51] A 2008 study found that the parents of gender-dysphoric children showed no signs of psychopathological issues aside from mild depression in the mothers.[49][52]
It has been suggested that the attitudes of the child's parents may affect the child's gender identity, although evidence is minimal.[53]
Parental establishment of gender roles
Parents who do not support gender nonconformity are more likely to have children with firmer and stricter views on gender identity and gender roles.[47] Recent literature suggests a trend towards less well-defined gender roles and identities, as studies of parental coding of toys as masculine, feminine, or neutral indicate that parents increasingly code kitchens and in some cases dolls as neutral rather than exclusively feminine.[54] However, Emily Kane found that many parents still showed negative responses to items, activities, or attributes that were considered feminine, such as domestic skills, nurturance, and empathy.[54] Research has indicated that many parents attempt to define gender for their sons in a manner that distances the sons from femininity,[54] with Kane stating that “the parental boundary maintenance work evident for sons represents a crucial obstacle limiting boys options, separating boys from girls, devaluing activities marked as feminine for both boys and girls, and thus bolstering gender inequality and heteronormativity.”[54]
Many parents form gendered expectations for their child before it is even born, after determining the child's sex through technology such as ultrasound. The child thus arrives to a gender-specific name, games, and even ambitions.[26] Once the child's sex is determined, most children are raised in accordance with it to be a man or a woman, fitting a male or female gender role defined partly by the parents.
Gender variance and non-conformance
In some cases, a person's gender identity is inconsistent with their biological sex characteristics (genitals and secondary sex characteristics), resulting in individuals dressing and/or behaving in a way which is perceived by others as outside cultural gender norms. These gender expressions may be described as gender variant, transgender, or genderqueer[55] (there is an emerging vocabulary for those who defy traditional gender identity),[56] and people who have such expressions may experience gender dysphoria (traditionally called "gender identity disorder" or GID); see #Gender dysphoria and gender identity disorder.
Many people consider themselves to belong to the binary gender which corresponds to their binary (male or female) sex, i.e. they are cisgender. Before the 20th century, a person's sex would be determined entirely by the appearance of the genitalia, but as chromosomes and genes came to be understood, these were then used to help determine sex. Those defined as women, by sex, have genitalia that are considered female and have two X chromosomes; those viewed as men, by sex, are seen as having male genitalia and one X and one Y chromosome. However, some individuals have combinations of these chromosomes, hormones, and genitalia that do not follow the traditional definitions of "men" and "women". In addition, genitalia vary greatly and a few individuals have more than one type of genitalia. Also, other bodily attributes related to a person's sex (body shape, facial hair, high or deep voice, etc.) may or may not coincide with their social category of man or woman. For example, a person with female genitalia, as well as a deep voice and facial hair, may have difficulty determining which gender they identify with. A survey of the research literature from 1955–2000 suggests that as many as one in every hundred individuals may have some intersex characteristic.[57] Intersex phenomena are not unique to humans. In a number of species, even more striking examples exist, for instance the bilateral gynandromorphic zebra finch (half-male, half-female body along its symmetry plane).[58][59]
Besides transgender people, other people who do not believe that their gender identity corresponds to the sex they were assigned at birth include many intersex individuals. One reason for such discordances in intersex people is that some individuals have a chromosomal or phenotypical sex that has not been expressed in the external genitalia because of hormonal or other conditions during critical periods in gestation. Such a person may later disagree with a clinical assignment of sex of rearing made at time of birth. Possible causes of transgenderism have also been studied; see #Biological causes of transgender and transsexuality.
In recent decades it has become possible to reassign sex surgically. Some people who experience gender dysphoria seek such medical intervention to have their physiological sex match their gender identity; others retain the genitalia they were born with (see transsexual for some of the possible reasons) but adopt a gender role that is consistent with their gender identity.
History and definitions
Definitions
The terms gender identity and core gender identity were first used with their current meaning — one's personal experience of one's own gender[1][60] — sometime in the 1960s.[61][62] To this day they are usually used in that sense,[3] though a few scholars additionally use the term to refer to the sexual orientation and sexual identity categories gay, lesbian and bisexual.[63]
Early medical literature
In late-19th-century medical literature, women who chose not to conform to their expected gender roles were called "inverts", and they were portrayed as having an interest in knowledge and learning, and a "dislike and sometimes incapacity for needlework". During the mid 1900s, doctors pushed for corrective therapy and such women and on children, which meant that gender behaviors that weren't part of the norm would be punished and changed. The aim of this therapy was to push children back to their "correct" gender roles and thereby limit the amount of children who became transgender.[64]
Freud and Jung's views
In 1905, Sigmund Freud presented his theory of psychosexual development in Three Essays on the Theory of Sexuality, giving evidence that in the pregenital phase children do not distinguish between sexes, but assume both parents have the same genitalia and reproductive powers. On this basis, he argued that bisexuality was the original sexual orientation and that heterosexuality was resultant of repression during the phallic stage, at which point gender identity became ascertainable. According to Freud, during this stage, children developed an Oedipus complex where they had sexual fantasies for the parent ascribed the opposite gender and hatred for the parent ascribed the same gender, and this hatred transformed into (unconscious) transference and (conscious) identification with the hated parent who both exemplified a model to appease sexual impulses and threatened to castrate the child's power to appease sexual impulses.[22] In 1913, Carl Jung proposed the Electra complex as he both believed that bisexuality did not lie at the origin of psychic life, and that Freud did not give adequate description to the female child (Freud rejected this suggestion).[65]
1950s and 1960s
During the 1950s and '60s, psychologists began studying gender development in young children, partially in an effort to understand the origins of homosexuality (which was viewed as a mental disorder at the time). In 1958, the Gender Identity Research Project was established at the UCLA Medical Center for the study of intersex and transsexual individuals. Psychoanalyst Robert Stoller generalized many of the findings of the project in his book Sex and Gender: On the Development of Masculinity and Femininity (1968). He is also credited with introducing the term gender identity to the International Psychoanalytic Congress in Stockholm, Sweden in 1963. Behavioral psychologist John Money was also instrumental in the development of early theories of gender identity. His work at Johns Hopkins Medical School's Gender Identity Clinic (established in 1965) popularized an interactionist theory of gender identity, suggesting that, up to a certain age, gender identity is relatively fluid and subject to constant negotiation. His book Man and Woman, Boy and Girl (1972) became widely used as a college textbook, although many of Money's ideas have since been challenged.[66][67]
Butler's views
In the late 1980s, Judith Butler began lecturing regularly on the topic of gender identity, and in 1990 she published Gender Trouble: Feminism and the Subversion of Identity, introducing the concept of gender performativity and arguing that both sex and gender are constructed.[68]
Present views
Society
The 21st century's generation commonly accepts boys openly playing with and dressing in things normally considered to be for girls. Children are often allowed to be in the "middle space” between traditional boyhood and traditional girlhood, with activities and toys from all across the gender spectrum.
Medical field
As of 2014, there is some changing of views and new discrepancies about the best way to deal with gender nonconformity. Many members of the medical field, as well as an increasing number of parents, no longer believe in the idea of corrective therapy. Instead, some psychologists and psychiatrists suggest that instead gender neutrality should be encouraged, in which people are not distinguished by their gender. It is believed that this will lead children to be more comfortable with themselves and their feelings. On the other hand, there is still a large number of clinicians who believe that there should be interventions for gender nonconforming children. They believe that stereotypical gender-specific toys and games will encourage children to behave in their traditional gender roles.[64]
Transsexual self-identified people sometimes wish to undergo physical surgery to refashion their primary sexual characteristics, secondary characteristics, or both, because they feel as if they will be more comfortable with different genitalia. This may involve removal of penis, testicles or breasts, or the fashioning of a penis, vagina or breasts. In the past, sex assignment surgery has been performed on infants who are born with ambiguous genitalia. However, current medical opinion is strongly against this procedure, since many adults have regretted that these decisions were made for them at birth. Today, Sex reassignment surgery is performed on people who choose to have this change so that their sexual identity will match their gender identity.[69]
In the United States, it was decided under the Affordable Care Act that health insurance exchanges would have the ability to collect demographic information on gender identity and sexual identity through optional questions, to help policymakers better recognize the needs of the LGBT community.[70]
Gender dysphoria and gender identity disorder
Gender dysphoria (previously called "gender identity disorder" or GID in the DSM) is the formal diagnosis of people who experience significant dysphoria (discontent) with the sex they were assigned at birth and/or the gender roles associated with that sex:[71][72] "In gender identity disorder, there is discordance between the natal sex of one's external genitalia and the brain coding of one's gender as masculine or feminine."[61] The Diagnostic and Statistical Manual of Mental Disorders (302.85) has five criteria that must be met before a diagnosis of gender identity disorder can be made, and the disorder is further subdivided into specific diagnoses based on age, for example gender identity disorder in children (for children who experience gender dysphoria).
The concept of gender identity appeared in the Diagnostic and Statistical Manual of Mental Disorders in its third edition, DSM-III (1980), in the form of two psychiatric diagnoses of gender dysphoria: gender identity disorder of childhood (GIDC), and transsexualism (for adolescents and adults). The 1987 revision of the manual, the DSM-III-R, added a third diagnosis: gender identity disorder of adolescence and adulthood, nontranssexual type. This latter diagnosis was removed in the subsequent revision, DSM-IV (1994), which also collapsed GIDC and transsexualism into a new diagnosis of gender identity disorder.[73] In 2013, the DSM-5 renamed the diagnosis gender dysphoria and revised its definition.[74]
The authors of a 2005 academic paper questioned the classification of gender identity problems as a mental disorder, speculating that certain DSM revisions may have been made on a tit-for-tat basis when certain groups were pushing for the removal of homosexuality as a disorder. This remains controversial,[73] although the vast majority of today's mental health professionals follow and agree with the current DSM classifications.
International human rights law
The Yogyakarta Principles, a document on the application of international human rights law, provide in the preamble a definition of gender identity as each person's deeply felt internal and individual experience of gender, which may or may not correspond with the sex assigned at birth, including the person's sense of the body (which may involve, if freely chosen, modification of bodily appearance or function by medical, surgical or other means) and other experience of gender, including dress, speech and mannerism. Principle 3 states that "Each person’s self-defined [...] gender identity is integral to their personality and is one of the most basic aspects of self-determination, dignity and freedom. No one shall be forced to undergo medical procedures, including sex reassignment surgery, sterilisation or hormonal therapy, as a requirement for legal recognition of their gender identity."[75] and Principle 18 states that "Notwithstanding any classifications to the contrary, a person's sexual orientation and gender identity are not, in and of themselves, medical conditions and are not to be treated, cured or suppressed."[76] Relating to this principle, the "Jurisprudential Annotations to the Yogyakarta Principles" observed that "Gender identity differing from that assigned at birth, or socially rejected gender expression, have been treated as a form of mental illness. The pathologization of difference has led to gender-transgressive children and adolescents being confined in psychiatric institutions, and subjected to aversion techniques — including electroshock therapy — as a 'cure'."[77] The "Yogyakarta Principles in Action" says "it is important to note that while 'sexual orientation' has been declassified as a mental illness in many countries, 'gender identity' or 'gender identity disorder' often remains in consideration."[78] These Principles influenced the UN declaration on sexual orientation and gender identity.
Non-Western gender identities
Fa'afafine
In some Polynesian societies, fa'afafine are considered to be a "third gender" alongside male and female. They are anatomically male, but dress and behave in a manner considered typically female. According to Tamasailau Sua'ali'i (see references), fa'afafine in Samoa at least are often physiologically unable to reproduce. Fa'afafine are accepted as a natural gender, and neither looked down upon nor discriminated against.[79] Fa'afafine also reinforce their femininity with the fact that they are only attracted to and receive sexual attention from straight masculine men. They have been and generally still are initially identified in terms of labour preferences, as they perform typically feminine household tasks.[80] The Samoan Prime Minister is patron of the Samoa Fa'afafine Association.[81] Translated literally, fa'afafine means "in the manner of a woman."[82]
Hijras
In some cultures of Asia, a hijra is usually considered to be neither a man nor a woman. Most are anatomically male or intersex, but some are anatomically female. The hijra form a third gender role, although they do not enjoy the same acceptance and respect as males and females in their cultures. They can run their own households, and their occupations are singing and dancing, working as cooks or servants, sometimes prostitutes, or long-term sexual partners with men. Hijras can be compared to transvestites or drag queens of contemporary western culture.[83]
Khanith
The khanith form an accepted third gender in Oman, a gender-segregated society. The khanith are male homosexual prostitutes whose dressing is male, featuring pastel colors (rather than white, worn by men), but their mannerisms female. Khanith can mingle with women, and they often do at weddings or other formal events. Khaniths have their own households, performing all tasks (both male and female). However, similarly to men in their society, khaniths can marry women, proving their masculinity by consummating the marriage. Should a divorce or death take place, these men can revert to their status as khaniths at the next wedding.[84]
Two-spirit identities
Many indigenous North American Nations had more than two gender roles. Those who belong to the additional gender categories, beyond cisgender man and woman, are now often collectively termed "two-spirit" or "two-spirited." There are parts of the community that take "two-spirit" as a category over an identity itself, preferring to identify with culture- or Nation-specific gender terms.

As before, high levels of hormones known as androgens will stop the hypothalamus from ever organizing hormone cycles. If there are low levels, then it will be cyclic.” This early influence on brain determines the different frequency of hormone secretion later in male or female’s life. “Obviously, women’s sex hormones usually follow a monthly cycle,” while “men’s sex hormones do not follow such a pattern.” Birke, Lynda.
