Gender stereotypes, aggression, and computer games: an online survey of women.

Computer games were conceptualized as a potential mode of entry into computer-related employment for women. Computer games contain increasing levels of realism and violence, as well as biased gender portrayals. It has been suggested that aggressive personality characteristics attract people to aggressive video games, and that more women do not play computer games because they are socialized to be non-aggressive. To explore gender identity and aggressive personality in the context of computers, an online survey was conducted on women who played computer games and women who used the computer but did not play computer games. Women who played computer games perceived their online environments as less friendly but experienced less sexual harassment online, were more aggressive themselves, and did not differ in gender identity, degree of sex role stereotyping, or acceptance of sexual violence when compared to women who used the computer but did not play video games. Finally, computer gaming was associated with decreased participation in computer-related employment; however, women with high masculine gender identities were more likely to use computers at work.

Gender: history, theory and usage of the term in sexology and its relationship to nature/nurture.

A person's sexual status is conventionally defined on the criterion of the external sex organs, and this criterion is presumed to be concordant with the other criteria of sex. When the sex organs are deformed, as in hermaphroditism, or mutilated, their sex role is to some extent affected, whereas all the other manifestations of the person's masculinity or femininity may be intact. Gender, not sex, is the umbrella term which refers to the totality of masculinity/femininity, genital sex included. Gender role and gender identity are two sides of the same coin, gender-identity/role (G-I/R). G-I/R may differentiate to be discordant with one or more of the basic sex variables which are now listed in the definition of sex in Dorland's Medical Dictionary. G-I/R is the product not of either nature or nurture acting alone, but of both in interaction at crucial periods of developmental differentiation. The new paradigm is nature/crucial-period/nurture, not nature/nurture. Social scientists and sexologists are among those who, for the most part, have not made the paradigm shift.

Male-to-female transsexuals have female neuron numbers in a limbic nucleus.

Transsexuals experience themselves as being of the opposite sex, despite having the biological characteristics of one sex. A crucial question resulting from a previous brain study in male-to-female transsexuals was whether the reported difference according to gender identity in the central part of the bed nucleus of the stria terminalis (BSTc) was based on a neuronal difference in the BSTc itself or just a reflection of a difference in vasoactive intestinal polypeptide innervation from the amygdala, which was used as a marker. Therefore, we determined in 42 subjects the number of somatostatin-expressing neurons in the BSTc in relation to sex, sexual orientation, gender identity, and past or present hormonal status. Regardless of sexual orientation, men had almost twice as many somatostatin neurons as women (P < 0.006). The number of neurons in the BSTc of male-to-female transsexuals was similar to that of the females (P = 0.83). In contrast, the neuron number of a female-to-male transsexual was found to be in the male range. Hormone treatment or sex hormone level variations in adulthood did not seem to have influenced BSTc neuron numbers. The present findings of somatostatin neuronal sex differences in the BSTc and its sex reversal in the transsexual brain clearly support the paradigm that in transsexuals sexual differentiation of the brain and genitals may go into opposite directions and point to a neurobiological basis of gender identity disorder.

Measuring physical aggressiveness in heterosexual, homosexual, and transsexual males.

The purpose of this study was the development of a self-report measure of boyhood aggressiveness for use with adult males. Aggressiveness was defined as a generalized disposition to engage in physically combative or competitive interactions with male peers. This attribute is of sexological interest because of the reported difference in physical aggressiveness between heterosexual and homosexual boys. A physical aggressiveness scale (PAS) was constructed from items regarding boyhood athletic interest and proficiency, as well as fighting with and feelings of unease around male peers. The PAS and Part A of the Feminine Gender Identity Scale for males (FGIS(A), Freund et al., 1977) were administered to 193 adult men. The PAS was shown to be reliable and factorially pure. The PAS scores of homosexuals were significantly lower than those of heterosexuals, and the scores of male-to-female transsexuals were lower yet. No differences were found among three heterosexual groups: prison inmates and nonuniversity- and university-educated males. Precisely symmetrical results were obtained with the FGIS(A), with the male-to-female transsexuals scoring highest and the heterosexuals lowest. Group differences in FGIS(A) scores were greater than those in PAS scores; this was interpreted as possible evidence that physical aggressiveness is more sensitive than gender identity to variables uncorrelated with erotic preference, e.g., perceptual-motor ability, rate of physical maturation, etc. The main results suggest that whatever underlying factor relates homosexuality to feminine gender identity in childhood relates this erotic preference to anomalously low levels of physical aggressiveness in childhood as well.

A multifactorial approach to the study of gender characteristics.

The present article reviews some of the central conceptual issues confronted by gender researchers as they have tried to forge a theory of gender identity that can account for the complexity and diversity of gender-related characteristics displayed by women and men. An emerging consensus suggests that gender is incorporated into an individual's self-concept in multiple and loosely connected ways. We review one example of this emerging multiplicity perspective, Spence's (1993) multifactorial gender identity theory, and describe three recent studies testing its usefulness. We also discuss ways in which multiplicity models of gender could benefit from considering parallel developments in the general personality literature regarding the problem of levels or domains. In particular, it is argued that McAdams's (this issue) integrative three-level model of the structure of personality offers a helpful framework for guiding future test construction and theory development in gender research.

[Assessment and treatment of transsexualism].

Transsexualism, a gender identity disorder, is manifested by a strong and persistent cross-gender identification and the desire to adapt the body to the preferred sex by hormonal and surgical sex reassignment. The etiology of gender identity disorder is not known. Treatment takes place gradually in phases in a interdisciplinary setting (psychiatry, endocrinology, gynecology and surgery). In Switzerland, in contrast to other European countries, there is no special legislation to regulate the change of the name and personal status.

Is gender dysphoria dysphoric? Elevated depression and anxiety in gender dysphoric and nondysphoric homosexual and bisexual men in an HIV sample. HNRC Group.

Few if any studies before the AIDS epidemic suggested that male homosexuals may on average have higher levels of depression than male heterosexuals. However, several samples of homosexual and bisexual men in HIV studies suggest that depression and anxiety are high in these populations, and that this psychiatric morbidity began before the AIDS epidemic. We tested the hypothesis that high childhood gender nonconformity (CGN) is associated with depression and anxiety, and so might account for differences in these variables among samples of homosexuals. A total of 254 homosexual or bisexual male subjects were assessed for depression, anxiety, and associated symptoms using various self-report and interview measures, as well as for CGN (using the Freund Feminine Gender Identity scale, FGI). For comparison purposes only, we also evaluated the subjects for the DSM-III diagnosis of Ego-Dystonic Homosexuality. Highly gender nonconforming men (high FGI scores) were more likely to have current symptoms of anxiety and depression by self-report, and to have had a lifetime history of depression by clinical interview. This association was more often due to FGI items dealing with childhood than adulthood. When the FGI was broken into subscales by a prior factor analysis, stepwise regression suggested that the subscale measuring core gender identity nonconformity (so-called "gender dysphoria") was more reliably associated with depression and anxiety than were the factors measuring nonconformity in the areas of masculine and feminine gender roles, or genitoerotic (sexual) roles. This subscale was also the only FGI measure correlating with Ego-Dystonic Homosexuality. AIDS (CDC stage and HIV serostatus) and age did not account for these findings. We conclude that the often-reported higher levels of depression, anxiety, and associated symptoms among homosexual and bisexual men in AIDS studies are more common in the subgroup of such men who are gender dysphoric. Theoretical and clinical implications of these data are discussed.

Androgen imprinting of the brain in animal models and humans with intersex disorders: review and recommendations.

PURPOSE: Psychosexual development, gender assignment and surgical treatment in patients with intersex are controversial issues in the medical literature. Some groups are of the opinion that gender identity and sexual orientation are determined prenatally secondary to the fetal hormonal environment causing irreversible development of the nervous system. We reviewed the evidence in animal and human studies to determine the possible role of early postnatal androgen production in gender development. MATERIALS AND METHODS: An extensive literature review was performed of data from animal experiments and human studies. RESULTS Many animal studies show that adding or removing hormonal stimulus in early postnatal life can profoundly alter gender behavior of the adult animal. Human case studies show that late intervention is unable to reverse gender orientation from male to female. Most studies have not permitted testing of whether early gender assignment and treatment as female with suppression/ablation of postnatal androgen production leads to improved concordance of the gender identity and sex of rearing. CONCLUSIONS: Animal studies support a role for postnatal androgens in brain/behavior development with human studies neither completely supportive nor antagonistic. Therefore, gender assignment in infants with intersex should be made with the possibility in mind that postnatal testicular hormones at ages 1 to 6 months may affect gender identity. A case-control study is required to test the hypothesis that postnatal androgen exposure may convert ambisexual brain functions to committed male behavior patterns.

The clinical syndromes of femmiphilic transvestism.

Thirty-four members of a club established for heterosexual transvestites were interviewed. They were categorized into two groups. Subjects in group I were satisfied with cross-dressing and did not desire additional feminization. Subjects in group II desired to alter their bodily appearance toward female by taking female hormones or by having surgical intervention. Group II transvestites cross-dressed more frequently and had a more intense feminine gender identity and stronger homosexual interests than did group I transvestites. A feminine gender identity appeared to be present from childhood in both groups but to be stronger in group II. Cross-dressing in subjects of both groups often occurred first during childhood and almost always prior to age 15. All subjects showed a period of fetishistic arousal to women's clothes during adolescence. With increasing age, fetishistic arousal diminished or disappeared and the frequency of cross-dressing increased. Terms in the literature used to describe the type of transvestism reported in this study are discussed. It was suggested that the term "femmiphilic transvestism" be used to describe the condition of the subjects of both groups. The term has fewer disadvantages than terms previously suggested.

On the evocability of a positive oestrogen feedback action on LH secretion in transsexual men and women.

In transsexual men with homosexual behaviour and intact testicular function, as well as in homosexual men with normal gender identity, following a negative oestrogen feedback effect a delayed positive oestrogen feedback action on LH secretion was evoked. By contrast, in transsexual men with hypo- or asexuality and intact testes or hypergonadotrophic hypo- or agonadism, as well as in heterosexual men with normal gender identity, a negative oestrogen feedback effect was not followed by a positive feedback action on LH release. In transsexual women with homosexual behaviour and oligo- and/or hypomenorrhoea, only a weak or at best moderate positive oestrogen feedback action on LH release was evocable, similarly as in castrated and oestrogen-primed heterosexual men. By contrast, in a transsexual woman with bisexual behaviour and eumenorrhoea, a strong positive oestrogen feedback action on LH secretion was evocable, as well as in heterosexual women with normal gender identity.

[Grouping of abnormal sexual development--guide to diagnosis].

Sexual differentiation and development is a process from the moment of fertilization of a ovum by a spermatozoon to achievement of reproductive ability as a male or female. The process includes three steps; establishment of sex chromosome composition, gonadal differentiation and development, and acquirement of phenotypic expression by gonadal hormones. Therefore, abnormal sexual development is divided into three categories according to the above three steps. In humans, however, gender is assigned at birth. Then, individuals grow under social environment provided according to the gender assigned and acquire gender role during childhood and gender identity during puberty. As observed in those with trans-sexualism, it appears likely that gender identity plays a major role on sexual behavior of humans.

Effects of pretrial publicity on male and female jurors and judges in a mock rape trial.

A study explored influence of pretrial publicity and gender identity on verdicts and severity of sentence in a mock rape trial. Mock jurors and judges were exposed to four pretrial publicity conditions before watching a simulated rape trial. After viewing the trial, jurors rendered a verdict (guilty or not guilty) and judges prescribed a sentence. The Bem Sex-role Inventory was used to analyze gender identity and its relation to verdict and sentencing. Verdicts were not influenced by pretrial publicity, but sentencing was more severe following exposure of mock judges to pretrial publicity about a mistaken acquittal and less severe following exposure of these judges to pretrial publicity about a mistaken conviction. Subjects classified by the Bem inventory as feminine or androgynous rendered a verdict of "guilty" more often than subjects classified as masculine or undifferentiated. Men who rendered verdicts of "guilty" had less confidence in their judgments than men who found the defendant "not guilty." Conversely, women who found the defendant "not guilty" expressed less confidence than women who found the defendant "guilty." The findings are compared and contrasted with similar studies and discussed in regards to gender identity, subjects' characteristics, and mode of presentation.

Male transsexuals in the homosexual subculture.

The author describes 20 male transsexuals who differ from most discussed in professional studies and from those in media portrayals in that they live in the male homosexual subculture. Furthermore, interviews with these individuals indicated that transsexuals are no more sexually or socially homogeneous than heterosexuals or homosexuals. In general, these men entered the homosexual subculture in their teens; they knew they were not heterosexual and therefore assumed they must be homosexual. As their gender identity crystallized, homosexual activity became repugnant and they rejected and were rejected by male homosexuals. Being unable to attract heterosexual men, they sought bisexual partners in a futile effort to confirm their identity as females. The author suggests that in addition to efforts to help transsexuals shift their gender identity, psychiatrists should emphasize prevention of this psychopathologic symptom.

Male pseudohermaphroditism: long-term quality of life outcome in five 46,XY individuals reared female.

We assessed the adult quality of life of five medical chart-selected genetic males (ages 29-34 years) assigned and reared as females due to ambiguity of the external genitalia. All five were treated following the traditional method proposed by John Money and colleagues in 1955, commonly referred to as the "optimal gender policy". The adult follow-up assessment included physical and endocrinological evaluation, completion of self-report questionnaires, and a semi-structured interview assessing gender identity, sexual experience and orientation. Quality of life domains assessed by questionnaire included health-related issues, satisfaction with health-care management, emotional distress, and relationship satisfaction. Vaginoplasty in four out of five patients was initially unsuccessful. Four patients had periodic lapses in adherence to hormone replacement therapy. Gender role behavior across development was masculine relative to norms for women. All participants reported a female gender identity without a history of gender dysphoria. The majority of participants (four of five) reported being sexually active and in long-term relationships (three heterosexual, one homosexual). Current emotional adaptation and health-related quality of life are within the normal range for four participants. Sex assignment of 46,XY individuals with ambiguous genitalia as females is compatible with a positive quality of life.

Psychological outcomes and gender-related development in complete androgen insensitivity syndrome.

We evaluated psychological outcomes and gender development in 22 women with complete androgen insensitivity syndrome (CAIS). Participants were recruited through a medical database (n = 10) or through a patient support group (n = 12). Controls included 14 males and 33 females, of whom 22 were matched to women with CAIS for age, race, and sex-of-rearing. Outcome measures included quality of life (self-esteem and psychological general well-being), gender-related psychological characteristics (gender identity, sexual orientation, and gender role behavior in childhood and adulthood), marital status, personality traits that show sex differences, and hand preferences. Women recruited through the database versus the support group did not differ systematically, and there were no statistically significant differences between the 22 women with CAIS and the matched controls for any psychological outcome. These findings argue against the need for two X chromosomes or ovaries to determine feminine-typical psychological development in humans and reinforce the important role of the androgen receptor in influencing masculine-typical psychological development. They also suggest that psychological outcomes in women with CAIS are similar to those in other women. However, additional attention to more detailed aspects of psychological well-being in CAIS is needed.

The Sambia "turnim-man": sociocultural and clinical aspects of gender formation in male pseudohermaphrodites with 5-alpha-reductase deficiency in Papua New Guinea.

Continuing controversy surrounding the Dominican Republic studies of 5-alpha-reductase deficiency and the development of gender identity in male pseudohermaphrodites concerns the roles of culture and biology in determining the ambiguity of gender socialization in an unsophisticated population. The present paper provides a cross-cultural perspective on these problems through description of anthropological and clinical data for a sample (N = 14) of subjects suffering from 5-alpha-reductase deficiency. Nine of these male pseudohermaphrodites were reared ambiguously as male and five as female. Female subjects changed from the female to male-identified role, but in circumstances of social trauma. The authors find ambiguity here related to the presence of a third sexual category available for sex-assignment and typing. Cultural valuation of the male role makes gender-switching from female to male pragmatically adaptive. The study concludes that social-experiential and cultural factors are significant in the formation of gender identity change in male pseudohermaphrodites with 5-alpha-reductase deficiency.

Tests of gender feelings and behavior in homosexuality, transvestism and transsexualism.

Categorized 64 male transsexual and transvestite Ss into two groups on the basis of the strength of their feminine gender identity. The two groups were compared to a homosexual group and a control group on four tests designed to measure gender feelings and behavior, namely: the California Personality Inventory Femininity Scale, the Draw-A-Person test, the Franck Drawing Completion test, and the Information and Vocabulary subtests of the WAIS. It was found that the CPI-Fe scale and DAP test significantly correlate with the degree of feminine gender identity reported by the Ss. However, the two tests appear to measure different aspects of gender feelings and behavior in some Ss.

Diagnostic approach to the newborn with ambiguous genitalia.

When assessing an infant with ambiguous genitalia, there are some important points to remember: Do not delay the evaluation of a patient with ambiguous genitalia. A delay may expose the patient unnecessarily to a life-threatening situation, such as a salt-losing crisis associated with 21-hydroxylase deficiency or one of the testosterone biosynthetic defects. Also, it is unfair to expect the family to be able to deal emotionally with the uncertainty of unresolved gender assignment. Never perform a buccal smear. There is absolutely no indication for performing a buccal smear at any point in the evaluation of any patient with ambiguous genitalia. Use of a buccal smear to determine gender assignment was helpful decades ago, before analysis of human chromosomes was possible. With current cytogenetic methodologies that can detect chromosomal mosaicism and subtle abnormalities of the X and Y chromosomes, there is never an indication to perform a buccal smear. Never make a gender assignment on the basis of the appearance of the external genitalia alone. The chromosomal sex and gonadal sex need to be determined first. The parents' feelings regarding the desired sex of the child, gender identity and fertility need to be discussed. Once there are sufficient data, gender assignment can be made. Gender assignment should be made as soon as possible after birth, but absolutely should be made by 18 months of age, when children develop gender identity. Never equivocate in the assignment of gender. The parents and the physicians must be absolutely certain of the gender assignment and must view their decision as final. Follow-up visits with the family ideally include an assessment of their acceptance of the gender assignment of the child. If there is ambivalence, steps must be taken to identify the source of ambivalence and to clarify the issues.
