Whether transgender people should be able to compete in sport in accordance with their gender identity is a widely contested question within the literature and among sport organisations, fellow competitors and spectators. Owing to concerns surrounding transgender people (especially transgender female individuals) having an athletic advantage, several sport organisations place restrictions on transgender competitors (e.g. must have undergone gender-confirming surgery). In addition, some transgender people who engage in sport, both competitively and for leisure, report discrimination and victimisation.

Common stereotypes associate high-level intellectual ability (brilliance, genius, etc.) with men more than women. These stereotypes discourage women’s pursuit of many prestigious careers; that is, women are underrepresented in fields whose members cherish brilliance (such as physics and philosophy). Here we show that these stereotypes are endorsed by, and influence the interests of, children as young as 6. Specifically, 6-year-old girls are less likely than boys to believe that members of their gender are “really, really smart.” Also at age 6, girls begin to avoid activities said to be for children who are “really, really smart.” These findings suggest that gendered notions of brilliance are acquired early and have an immediate effect on children’s interests.

There is a widespread belief that women are better at selecting gifts than men; however, this claim has not been assessed on the basis of objective criteria. The current studies do exactly that and show that women do indeed make better gift selections for others, regardless of the gender of the receiver and the type of relationship between the giver and receiver. We investigate the mediating role of different aspects of interpersonal sensitivity and reveal that differences in interpersonal interest (measured with an autism questionnaire), but not differences in interpersonal reactivity, explain gender differences in gift selection quality. The current studies thus present the first objective evidence for the claim that women are better in selecting gifts for others and also give an indication of why this is the case.

On July 13, 2015, U.S. Defense Secretary Ashton Carter announced that the military anticipates lifting its ban on service by transgender persons, those whose gender identity does not match the sex that they were assigned at birth. Although an estimated 12,800 transgender personnel currently serve in the U.S. armed forces (see table for explanations of estimates), they must conceal their gender identity because military policy bans them from serving and prohibits military doctors from providing transition-related care. Although some transgender people do not change their bodies to match their gender identities, government agencies, courts, and scientists agree that for many, transition-related . . .

Across Europe, Canada, and the United States, 22-43 % of transgender (trans) people report a history of suicide attempts. We aimed to identify intervenable factors (related to social inclusion, transphobia, or sex/gender transition) associated with reduced risk of past-year suicide ideation or attempt, and to quantify the potential population health impact.

There is a general opinion that penile skin lined neovagina of transsexual women is not able to support the growth of lactobacilli. This study was undertaken to prove if lactobacilli strains could survive in neovagina and to characterise the most dominant Lactobacillus species. Sixty three male-to-female transsexual women without abnormal vaginal discharge, clinical signs of infection were recruited on an ongoing basis from among transsexual outpatients in an academic research institution and tertiary care centre. Neovaginal smears were taken for molecular Lactobacillus spp. profiling by denaturing gradient gel electrophoresis (PCR-DGGE). Lactobacillus species were detected from 47/63 transsexual women (75%). The 279 Lactobacillus signals detected by PCR-DGGE technique belonged to 13 different species. Lactobacilli of the L. delbrueckii group (L. gasseri, L. crispatus, L. johnsonii, L. iners, L. jensenii) were predominant. More than 90% of women harboured a combination of two or more neovaginal Lactobacillus species. In this study we report the frequent occurrence of lactobacilli from neovagina of transsexual women. Both, frequency and composition were similar to the normal lactic acid bacterial microflora in both women of reproductive age and postmenopausal women.

Many previous studies have reported robust sex differences in olfactory perception. However, both men and women can be expected to vary in the degree to which they exhibit olfactory performance considered typical of their own or the opposite sex. Sex-atypicality is often described in terms of childhood gender nonconformity, which, however, is not a perfect correlate of non-heterosexual orientation. Here we explored intrasexual variability in psychophysical olfactory performance in a sample of 156 individuals (83 non-heterosexual) and found the lowest odor identification scores in heterosexual men. However, when childhood gender nonconformity was entered in the model along with sexual orientation, better odor identification scores were exhibited by gender-nonconforming men, and greater olfactory sensitivity by gender-conforming women, irrespective of their sexual orientation. Thus, sex-atypicality, but not sexual orientation predicts olfactory performance, and we propose that this might not be limited to olfaction, but represent a more general phenomenon.

Many studies have shown that women use the Internet more often for health-related information searches than men, but we have limited knowledge about the underlying reasons. We also do not know whether and how women and men differ in their current use of the Internet for communicating with their general practitioner (GP) and in their future intention to do so (virtual patient-physician relationship).

Social transitions are increasingly common for transgender children. A social transition involves a child presenting to other people as a member of the “opposite” gender in all contexts (e.g., wearing clothes and using pronouns of that gender). Little is known about the well-being of socially transitioned transgender children. This study examined self-reported depression, anxiety, and self-worth in socially transitioned transgender children compared with 2 control groups: age- and gender-matched controls and siblings of transgender children.

Transgender individuals have a gender identity that differs from the sex they were assigned at birth. The population size of transgender individuals in the United States is not well-known, in part because official records, including the US Census, do not include data on gender identity. Population surveys today more often collect transgender-inclusive gender-identity data, and secular trends in culture and the media have created a somewhat more favorable environment for transgender people.
