RESUMO
Our understanding of sex and gender evolves. We asked scientists about their work and the future of sex and gender research. They discuss, among other things, interdisciplinary collaboration, moving beyond binary conceptualizations, accounting for intersecting factors, reproductive strategies, expanding research on sex-related differences, and sex's dynamic nature.

Neuroimaging (NI) technologies are having increasing impact in the study of complex cognitive and social processes. In this emerging field of social cognitive neuroscience, a central goal should be to increase the understanding of the interaction between the neurobiology of the individual and the environment in which humans develop and function. The study of sex/gender is often a focus for NI research, and may be motivated by a desire to better understand general developmental principles, mental health problems that show female-male disparities, and gendered differences in society. In order to ensure the maximum possible contribution of NI research to these goals, we draw attention to four key principles-overlap, mosaicism, contingency and entanglement-that have emerged from sex/gender research and that should inform NI research design, analysis and interpretation. We discuss the implications of these principles in the form of constructive guidelines and suggestions for researchers, editors, reviewers and science communicators.

Why is popular understanding of femalemale differences still based on rigid models of development, even though contemporary developmental sciences emphasize plasticity? Is it because the science of sex differences still works from the same rigid models?

In May 2011, more than a decade after the International Association of Athletics Federations (IAAF) and the International Olympic Committee (IOC) abandoned sex testing, they devised new policies in response to the IAAF's treatment of Caster Semenya, the South African runner whose sex was challenged because of her spectacular win and powerful physique that fueled an international frenzy questioning her sex and legitimacy to compete as female. These policies claim that atypically high levels of endogenous testosterone in women (caused by various medical conditions) create an unfair advantage and must be regulated. Against the backdrop of Semenya's case and the scientific and historical complexity of "gender verification" in elite sports, we question the new policies on three grounds: (1) the underlying scientific assumptions; (2) the policymaking process; and (3) the potential to achieve fairness for female athletes. We find the policies in each of these domains significantly flawed and therefore argue they should be withdrawn.

Extensive medical, public health, and social science research have focused on cataloguing male-female differences in human health. Unfortunately, much of this research unscientifically and unquestionably attributes these differences to biological causes--as exemplified in the Institute of Medicine's conclusion that "every cell has a sex." In this manuscript we theorize the entanglement of sex and gender in human health research and articulate good practice guidelines for assessing the role of biological processes--along with social and biosocial processes--in the production of non-reproductive health differences between and among men and women. There are two basic tenets underlying this project. The first is that sex itself is not a biological mechanism and the second is that "sex" and "gender" are entangled, and analyses should proceed by assuming that measures of sex are not pristine, but include effects of gender. Building from these tenets--and using cardiovascular disease as a consistent example--we articulate a process that scientists and researchers can use to seriously and systematically assess the role of biology and social environment in the production of health among men and women. We hope that this intervention will be one further step toward understanding the complexity and nuance of health outcomes, and that this increased knowledge can be used to improve human health.

One of the most consistent observations in the epidemiology of autism spectrum disorders (ASD) is the preponderance of male cases. A few hypotheses have been put forth which attempt to explain this divergence in terms of sex-linked biology, with limited success. Feminist epidemiologists suggest the importance of investigating specific mechanisms for male-female differences in health outcomes, which may include sex-linked biology and/or gender relations, as well as complex biosocial interactions. Neither domain has been systematically investigated for autism, and the possible role of gender has been particularly neglected. In this article, we posit hypotheses about how social processes based on perception of persons as male or female, particularly patterns of social and physical interaction in early development, may affect the observed occurrence and diagnosis of ASD. We gesture toward an embodiment model, incorporating hypotheses about initial biological vulnerabilities to autism--which may or may not be differentially distributed in relation to sex biology--and their interactions with gender relations, which are demonstrably different for male and female infants. Toward building such a model, we first review the epidemiology of ASD with an eye toward male-female differences, then present a theory of gender as a "pervasive developmental environment" with relevance for the excess burden of autism among males. Finally, we suggest research strategies to further investigate this issue.

Brain organization theory suggests that steroid hormones during fetal development permanently organize the brain for gender, including patterns of sexuality, cognition, temperament, and interests that differ by sex. This widely-accepted theory has important implications for health, ranging from medical management of infants with intersex conditions to suggested etiologies for sex differences in autism, depression, and other mental health problems. Studies of genetic females with congenital adrenal hyperplasia (CAH), in which high prenatal androgens have been linked to both atypical genitals and "masculine" patterns of gender and sexuality, are particularly important. Based on a comprehensive review of research on CAH, this article demonstrates that such studies have neglected four broad categories of variables that plausibly affect psychosexual development: (1) physiological effects of CAH, including complex disruption of steroid hormones from early development onwards; (2) intensive medical intervention and surveillance, which many women with CAH describe as traumatic; (3) direct effects of genital morphology on sexuality (versus indirect effects that "masculine" genitals may have on gender socialization); and (4) expectations of masculinization that likely affect both the development and evaluation of gender and sexuality in CAH. Complex and iterative interactions among postnatal biological variables, medical interventions, and social context provide a more plausible explanation for atypicalities in psychology and behavior that have been reported for genetic females with CAH than the conventional explanation that early androgens have "masculinized" their brains.
