Sex role endorsement among homosexual men across the life span.

This study assessed the sex role endorsement of homosexual men at different ages across the life span. A sample of homosexual men from dignity chapters in the northeastern, midwestern, southern, southwestern, and western United States was mailed a demographic questionnaire and th Bem Sex Role Inventory. Respondents were classified into four age brackets and categorized as androgynous, masculine, feminine, and undifferentiated. A pattern of diverse sex role endorsement was found from adolescence to maturity in which gay men were equally androgynous, masculine, feminine, and undifferentiated at each age level. This finding contradicted an earlier study of heterosexual men that reported increasing numbers of androgynous males with age. The contrast suggests that the sex role endorsement of gay men may be very different from their heterosexual counterparts. It was further suggested tht gay men are capable of meshing masculine and feminine aspects of their personalities early as well as later in life, that gay men do not comprise a homogeneous group, and that the stereotype of cross-gender role endorsement is unfounded.

Sex, gender role orientation, gender role attitudes and suicidal thoughts in three generations. A general population study.

BACKGROUND: Suicide and other suicidal behaviours are markedly (though differently) patterned by gender. The increase in young male suicide rates in many countries has heightened interest in whether suicidal behaviours and ideation (thoughts) are related to masculinity. Relatively little research has explored the relationship between gender role attitudes and orientation and suicidal behaviours and ideation. Most research in this area has been conducted with young people. OBJECTIVE: We investigated whether gender role orientation (masculinity and femininity scores) and gender role attitudes were related to the reporting of serious suicidal thoughts in three generations (early adulthood, and early and late middle age) in a community sample. METHODS: Subjects (653 men and women aged around 23 years, 754 aged around 43 years, 722 aged around 63 years) completed home interviews with nurses as part of an ongoing longitudinal community-based study of social factors and health. These included measures of suicidal ideation (thoughts), attitudes to traditional gender roles, and a validated measure of gender role orientation (masculinity and femininity scores). RESULTS: The prevalence of serious suicidal thoughts was higher in early adulthood (10% men, 15% women) than in early (4% men, 8% women) and late (6% men, 5% women) middle age. In early adulthood only sex was significantly related to suicidal thoughts, with women at higher risk (adjusted OR 1.74, 95% CI 1.01-3.00). In early middle age masculinity scores were negatively related to suicidal thoughts (adjusted OR for each unit increase in score 0.65: 95% CI 0.46-0.93), and more traditional views on gender roles were positively associated with suicidal thoughts (adjusted OR 1.48: 95% CI 1.07-2.04). In late middle age trends were in the same direction as in early middle age, but were not statistically significant. Femininity scores were unrelated to serious suicidal thoughts at any age. CONCLUSION: The high rates of suicidal thoughts amongst men and women in early adulthood point to the importance of understanding mental health problems at this age. The results raise a number of questions and suggest that suicide researchers should pay more attention to gender roles and attitudes in older adults.

[A questionnaire study of the relationship between gender and chronic pain].

INTRODUCTION: The aim of this study was to assess the relationship between gender role orientation and the prevalence of chronic pain. METHOD: The individual gender role orientation in a sample of 45 chronic pain patients (ICD 10 diagnosis, F 45.4) was compared to gender role orientation in a matched, pain-free control group. Gender role orientation was assessed by questionnaires on the self-attribution of stereotypic gender traits (GEPAQ) and on the extent of agreement with traditional feminine and masculine role norms (MRNS, FRNS). Group differences were compared by multivariate analysis. RESULTS: In accordance with the hypothesis, results confirmed that pain patients showed stronger feminine and weaker masculine role orientations than healthy controls. Pain patients additionally ascribed to themselves more 'feminine' (e.g. worried, nervous) and less 'masculine' (e.g. aggressive, cynical) traits. CONCLUSION: Sociopsychological variables of gender role orientation were related to chronic pain in the groups observed. An integrated model consisting of psychodynamic, sociological, and sociopsychological factors is proposed.

Quality of life and gender identity in Parkinson's disease.

UNLABELLED: We examined the correlation between gender identity (perception of masculinity or femininity) and quality of life (QoL) of 124 Parkinson's disease (PD) patients without dementia (69 men, 55 women, mean age 65.8+/-10.2 years, mean disease duration 8.5+/-5.8 years, mean Hoehn and Yahr [H&Y] stage 2.7+/-0.8). All patients underwent clinical examinations and completed the PDQ-39 and the quality of sexual life questionnaire. Their masculine or feminine stereotypes were determined by the Bem Sex Role Inventory (BSRI) modified by Dior. QoL was significantly correlated with disease duration (r=0.262, p<0.01), H&Y staging (r=0.330, p<0.001) and disease severity (UPDRS) (r=0.432, p<0.001). The QoL of androgynous men and women (i.e., with strong feminine and masculine characteristics) was significantly (p<0.05) better than the other gender groups. A significant interaction was found between the sexes to gender identity (p<0.05). CONCLUSION: Androgynous PD patients cope better with their disease in terms of QoL parameters, especially androgynous women.

Sexual orientation and gender: stereotypes and beyond.

In this essay, I explore empirical research about the relationship between sexual orientation and gender. Both concepts have multiple meanings, which hinder an unequivocal understanding of the relationship between the two concepts. One of the first studies assumed to establish a relationship between male homosexuality and femininity was conducted by L. M. Terman and C. C. Miles (1936). The study actually gives a much more complicated picture of the relationship. Terman and Miles actually found two groups of homosexual men with, respectively, extremely high masculinity and extremely high femininity scores. Subsequently, various other studies examined the relationship between sexual orientation and gender, introducing the concept of androgyNY. While these studies were executed, major changes took place in the homosexual world, which have been characterized as the masculinization of culture. It is unclear how these changes relate to the masculine and feminine properties of the men involved. Various suggestions are made for further research on the relation between gender and sexual orientation.

Gender role orientation and anxiety symptoms among African american adolescents.

The present study evaluated gender role theory as an explanation for the observed gender differences in anxiety symptoms among adolescents. Specifically, the relation between gender, gender role orientation (i.e., masculinity and femininity), self-esteem, and anxiety symptoms was examined in a community sample of 114 African Americans aged 14 to 19 (mean age 15.77; 57 girls). Results revealed that masculinity was negatively associated with anxiety symptoms whereas femininity was positively associated with anxiety symptoms. Gender role orientation accounted for unique variance in anxiety scores above biological gender and self-esteem, and self-esteem moderated the relation between femininity (but not masculinity) and overall anxiety symptoms. Consistent with research on children and Caucasians, findings supported gender role theory as a partial explanation for the observed gender disparity in anxiety symptoms among African American adolescents.

Influence of environmental events immediately after birth on postnatal testosterone secretion and adult sexual behavior in the male rat.

A rise in plasma testosterone (T) levels occurs in male rats during the first 2 hr after birth which is of importance for the process of sexual differentiation. To study the influence of environmental factors on the postnatal T surge and sexual development, newborn male rats were subjected to various treatments immediately after cesarean delivery including cooling, ether anesthesia, and mother-infant separation. In adulthood, the animals were observed for masculine and feminine sexual behavior. Males anesthetized at 0 hr showed elevated levels of feminine sexual behavior and impaired masculine sexual behavior. Pups subjected to cooling or mother-infant separation showed slightly prolonged intromission latencies, but otherwise normal levels of feminine sexual behavior. Significantly elevated plasma T levels were found in intact pups 2 hr after birth but not in pups subjected to cooling or ether anesthesia. Significantly higher levels of T were observed in pups subjected to cooling 4 hr after birth, suggesting a delay of the T surge. The most pronounced impairing effects were seen in the defeminization process, but the masculinization process also is affected by ether anesthesia. It was concluded that ether anesthesia immediately after birth may permanently interfere with the sexual development by suppressing the neonatal T surge.

Crosscultural comparison on nursing image.

Conceptual ratings for 'Nurse' and 'Feminine' were investigated across 30 language/culture communities. Data were from Osgood's Atlas of Affective Meanings, which contains ratings of 1200 males from each culture on 620 concepts, using Semantic Differentials. The study provides important information regarding the image of nurses crossculturally and the close link between nursing and femininity. In general, both 'Nurse' and Feminine' were perceived to be good and active, yet weak. A crosscultural view of the nurse as impotent may limit nursing's ability to deliver health care.

Genomic regulation of sexual behavior.

Estrogen receptors are distributed in discrete areas of the hypothalamus, preoptic area and amygdala of the rat brain, and in some of these areas estrogens induce progestin receptor sites. Estradiol (E), followed by progesterone (P), induce feminine sexual behavior in female, but not in male, rats. This induction takes time (on the order of hours, not minutes, so that the hormone may be cleared from the body) and is dependent on RNA and protein synthesis. Within the hypothalamic ventromedial nuclei (VMN), E and P induce changes in RNA and protein synthesis and also induce morphological changes indicative of cellular growth, genomic activation, and either new synapse formation or morphological rearrangement of existing synapses. Neurochemically, a number of neurotransmitter systems are implicated in the control of feminine sexual behavior, including acetylcholine, serotonin, GABA, and the neuropeptides, oxytocin and CCK. One of the means by which E and P may exert their influence on sexual behavior, aside from the morphological alterations, is by regulating levels of receptors for certain of these neurotransmitters. The critical differences which underlie the inability of male rats to display high levels of feminine sexual behavior after E plus P priming may depend on sex differences in the ability of E to induce particular neurochemical products as well as P receptors and upon differences in neural circuitry in the VMN.

Role of androgen, estrogen and sexual experience on the female rat's partner preference.

Virgin ovariectomized rats were implanted with Silastic tubings containing estradiol (E2, 5 mm), testosterone (T, 30 mm), dihydrotestosterone (DHT, 30 mm), or injected daily SC with the synthetic nonaromatizable androgen, methyltrienelone (R 1881, 5 mg.kg-1) daily for three weeks. Animals were tested for partner preference behavior (staying in the vicinity of a sexually active male, an estrous female or staying elsewhere) before and after they had been tested for feminine and masculine sexual behavior. All naive androgen-treated groups showed a male-oriented preference, while the naive E2-treated females did not show any consistent partner preference. Sexual experience abolished the male-directed orientation of the androgen-treated groups while E2 treatment induced a male-directed orientation. E2-treated females spent significantly longer time elsewhere in both tests compared to the other groups which might be due to insufficient levels of E2. Feminine sexual behavior was seen after treatment with E2 or T but not after treatment with DHT or R 1881. It was concluded, 1) that the effect of treatment with an androgen on the partner preference behavior differs according to whether the females are virgins or sexually experienced, and 2) the effect of the hormone treatment on the partner preference behavior is independent of whether the hormone stimulates feminine sexual behavior.

Two types of lordosis-inhibiting systems in male rats: dorsal raphe nucleus lesions and septal cuts.

To examine the functional relationships between the dorsal raphe nucleus and the septum in the inhibitory regulation of feminine sexual behavior in male rats, castrated male rats received destruction of the dorsal raphe nucleus (DRL), interruption of the septal outputs (ARD), or both DRL and ARD (DRL+ARD). All animals were treated with estradiol by using Silastic tubes, and feminine sexual behavior was observed every other day for 10 days. Most castrated control male rats did not show lordosis throughout the tests. In contrast, all of the males with DRL alone or ARD alone displayed lordosis, but the lordosis quotients (LQ) in these groups were lower than those of the female control group. On the other hand, DRL+ARD males showed higher LQs than the DRL or the ARD males, being comparable to control females. Thus, two types of strong inhibitory influence exist in the dorsal raphe nucleus and the septum, and resist the facilitation of feminine sexual behavior by estrogen in male rats. Furthermore, these inhibitory systems operate independently, because an additive effect of DRL and ARD in facilitating lordosis was clearly observed in DRL+ARD males.

Perinatal exposure to morphine affects adult sexual behavior of the male golden hamster.

Duromorph, a long-acting form of morphine, was administered to pregnant golden hamsters and/or their pups over the last 4 days of pregnancy and/or the first 4 days after birth. As adults, offspring were gonadectomized, primed with estrogen and progesterone, and tested for their ability to display feminine sexual behavior when placed with a stud male. They were then given testosterone over a 4-week period and tested for their ability to display masculine sexual behavior in the presence of a receptive female. Perinatal morphine exposure had little effect on the females' ability to display either feminine or masculine sexual behavior. In contrast, feminine sexual behavior was significantly enhanced in males exposed to morphine over the perinatal period. This suggests that exposure to opiates during the critical period of sexual differentiation may prevent the defeminization process in this species.

The effect of medial preoptic--anterior hypothalamic lesions on bisexual behavior of the male rat.

The effects of bilateral radiofrequency lesions in various parts of the medial preoptic area (mPOA) and anterior hypothalamus (AH) on masculine and hormone induced feminine sexual behavior was studied in male rats. Anatomical as well as statistical analysis of the extent and location of the lesions and the consequent behavioral changes indicated that different parts of the mPOA-AH continuum are involved in masculine and feminine sexual behavior in different ways. Bilateral destruction at the transition of the mPOA and AH resulted in a large reduction of masculine sexual activity while lesions concentrated in the AH slightly facilitated feminine sexual behavior in males. These results are consistent with the notion that the mPOA-AH continuum is divided into anatomically and functionally different parts.

Sexual response in the patient after hysterectomy: total abdominal versus supracervical versus vaginal procedure.

OBJECTIVE: The present study examines the patient's own appraisal of her sexual responsiveness after hysterectomy. STUDY DESIGN: Four hundred women who had undergone hysterectomy within a 3-year period were selected randomly and asked to respond to a questionnaire that was devised to ascertain the patient's own objective evaluation of self-image, sexuality, and sexual response before and after hysterectomy. The confidential responses were analyzed, noting the presence of any significant divergence between demographic and procedural cohorts. RESULTS: Of 126 respondents, 48.4% underwent total abdominal hysterectomy; 34.1% underwent vaginal hysterectomy, and 17.4% underwent supracervical hysterectomy. The mean patient age was 49.7+/-8.7 years. No direct correlation was found between hysterectomy type and age. Most women did not report any significant deterioration in mental attitude after the procedure (P =.788). Self and body image also remained consistent, with only 25.3% indicating a change for the worse. Only 10.3% of respondents felt less feminine after hysterectomy; nearly 70% of the respondents did not feel less feminine. Responses that pertained to libido, sexual activity, or feelings of femininity did not reveal significant changes (P >.05). Satisfaction with procedural choice was positive (54.8%), with only 7.1% responding unfavorably. CONCLUSION: The responses suggest that neither self-image nor sexuality need diminish after hysterectomy. The type of hysterectomy that was performed did not appear to affect the attitudes of the respondents.

A comparison of breast, testicular and prostate cancer in mass print media (1996-2001).

This paper compares the portrayal of breast, testicular and prostate cancer in mass print English language magazines in the United States and Canada from 1996 to 2001. It is a follow-up of three papers that examined each of these three diseases separately in high circulating magazines up to 1995. It includes both quantitative and qualitative analyses of magazine stories and notes the continuing dominance of a medical perspective regarding disease as well as the association of each type of cancer examined with stereotypically individualized yet feminine and masculine characteristics and pursuits. It notes the conflation of breast cancer, since the discovery of BRCA1 and BRCA2, with the family. To be a 'feminine' woman is to be vulnerable to breast cancer and to be a 'masculine' man is to be vulnerable to testicular cancer when young and prostate cancer when older. The association of disease not just with personhood but also with the specifics of stereotyped masculinity and femininity may construct a more intimate, more personal link between disease and identity. This close attachment of gender and disease may shore up and exacerbate a fear reaction. It may also serve to diminish the awareness of other, more prevalent, causes of death for men and women. The social control consequences of potentially exacerbated disease-specific fear are discussed.

Menstrual cycle, trait estrogen level, and masculinity preferences in the human voice.

Men with low testosterone (feminine men) invest in relationships and offspring more than men with high testosterone (masculine men). Women's attraction to testosterone dependent traits (e.g. masculine face shape) is enhanced during the late-follicular, fertile phase of the menstrual cycle. Attractive, feminine women have stronger preferences for masculine men as possible long-term partners than less attractive, masculine women. We manipulated 2 testosterone related vocal traits (voice pitch and apparent vocal-tract length) in voices to test if women prefer masculinized men's voices to feminized men's voices; masculinity preferences are enhanced at the fertile (late-follicular) menstrual cycle phase; the amount that masculinity preferences shift cyclically relates to average estrone-3-glucuronide concentration (the primary urinary metabolite of estrone, E3G). We found women displayed general masculinity preferences for men's voices; masculinity preferences were greater in the fertile (late-follicular) phase of the cycle than the non-fertile (early-follicular and luteal) phase; and this effect was most pronounced for women with low average E3G concentration. As feminine women (i.e. those with high average E3G levels) are most able to obtain investment even from masculine men, these women may not need to change their mating preference or strategy during the menstrual cycle as much as masculine women.

Determination of total menstrual blood loss.

OBJECTIVE: To develop and validate a simple method of measuring total menstrual blood loss using a pictorial representation of blood loss, the menstrual pictogram. DESIGN: A prospective evaluation of total menstrual blood loss measurement by the menstrual pictogram compared to the alkaline hematin technique. SETTING: Academic menorrhagia research clinic. PATIENT(S): One hundred twenty-one women; 62 women complaining of heavy menstrual blood loss, 59 women who considered their menstrual blood loss to be normal. INTERVENTION(S): Participants were asked to complete the menstrual pictogram through the period and collect their feminine hygiene products for an alkaline hematin assessment. MAIN OUTCOME MEASURE(S): Percentage agreement between blood loss measured by the gold standard alkaline hematin method and the menstrual pictogram. Extraneous blood loss was measured using a semiquantitative pictorial method. RESULT(S): The menstrual pictogram had a high level of agreement for blood collected on feminine hygiene products compared with the alkaline hematin method. Some women also lose a significantly large amount of extraneous blood, which is not proportional to the alkaline hematin blood loss assessment. CONCLUSION(S): The menstrual pictogram provides a simple means of measuring menstrual blood loss. It is no longer appropriate to ignore extraneous blood loss, particularly as there is no correlation between extraneous blood loss and that measured on feminine hygiene products.

Sexual and olfactory preference in noncopulating male rats.

In some species including rats, mice, gerbils, and rams, apparently normal males fail to copulate when repeatedly tested with receptive females. These animals are called "noncopulators (NC)," and the cause of this behavioral deficit is unknown. It has been shown that NC rats do not have hormonal alterations or deficits in the mechanisms that control penile function. The present study was designed to examine (Experiment 1) whether NC male rats prefer receptive females to sexually active males. In addition, the olfactory preference for bedding soiled from estrous or for anestrous bedding was investigated. These tests were performed in NC and copulating (C) male rats when the subjects were intact, gonadectomized (GDX), or GDX and treated with high doses of testosterone propionate (TP). Our results demonstrate that NC rats do not display sexual behavior even after high TP treatment. While C male rats have a clear preference for receptive females as opposed to a sexually active male, NC rats do not. In all hormonal conditions, the preference shown by NC rats for estrous bedding was significantly reduced in comparison to that seen in C rats. TP treatment in NC rats did not modify either partner or odor preference. In Experiment 2, we evaluated if NC rats are feminized and if it could be easier to induce feminine-like behavior by hormone treatment with estradiol benzoate (EB) or with EB plus progesterone (P) (EB+P). Odor preference for estrous or male bedding under these hormonal conditions was also compared. No differences between NC and C rats were found in feminine sexual behavior. In the olfactory test, we found that NC rats prefer odors from receptive females as opposed to male odors, but this preference is reduced compared to that of C rats. Males treated with EB or EB+P show no preference for female odors. These results demonstrate that treatment with EB or EB+P does not increase feminine sexual behavior in NC rats.
