Abstract Rising global temperatures threaten to disrupt population sex ratios, which can in turn cause mate shortages, reduce growth and adaptive potential, increase extinction risk, particularly when ratios are male biased. Sex ratio distortion then have cascading effects across other species even ecosystems. Our understanding of the problem is limited by how often studies measure temperature both sexes. To address this, current review surveyed 194 published heat tolerance, finding that majority did not mention individuals used, with <10% reporting results for males females separately. Although data incomplete, this assessed phylogenetic patterns thermally induced bias 3 different mechanisms: sex-biased temperature-dependent determination (TSD), temperature-induced reversal. For documented examples span a large taxonomic range including arthropods, chordates, protists, plants. Here, superior tolerance more common than males, but direction appears be phylogenetically fluid, perhaps due number contributing factors. TSD, well-documented reptiles, where high usually favors females, fishes, consistently males. reversal, unambiguous cases again vertebrates, fishes amphibians, mixed reptiles. There urgent need further work on full extent distortion, joint multiple mechanisms.

As part of an initiative to improve rigor and reproducibility in biomedical research, the U.S. National Institutes Health now requires consideration sex as a biological variable preclinical studies. This new policy has been interpreted by some call compare males females with each other. Researchers testing for differences may not be trained do so, however, increasing risk misinterpretation results. Using list recently published articles curated Woitowich et al. (eLife, 2020; 9:e56344), we examined reports non-differences across nine disciplines. Sex were claimed majority 147 analyzed; statistical evidence supporting those was often missing. For example, when sex-specific effect manipulation claimed, authors usually had tested statistically whether responded differently. Thus, effects over-reported. In contrast, also encountered practices that could mask differences, such pooling sexes without first difference. Our findings support need continuing efforts train researchers how test report order promote research.Biomedical research long history including only men or male laboratory animals To address this disparity, United States (NIH) rolled out 2016 called Biological Variable (or SABV). The funded NIH include every experiment unless there is strong justification to, studies ovarian cancer. Since then, number papers both continued grow. Although does require investigators females, many have SABV so. led would otherwise unrecognized ignored. However, on best their data, if data are analyzed appropriately lead misleading interpretations. Here, Garcia-Sifuentes Maney methods 2019 included females. They discovered more than half these reported but claims always backed evidence. Indeed, large (more 70%) describing treatment, impact treatment actually compared between sexes. suggests instances where masked due from being pooled together difference first. These reveal easy it draw conclusions sex-based data. hope work raises awareness issue encourages development training materials researchers.

Sex differences exist in many neurological and psychiatric diseases, but these have not always been addressed adequately research. In order to address this, it is necessary consider how sex incorporated into the design (e.g. using a balanced design) analyses as covariate) published literature. We surveyed papers 2009 2019 across six journals neuroscience psychiatry. this sample, we find 30% increase percentage of reporting studies that included both sexes compared with 2009. Despite increase, only 19% sample reported an optimal for discovery possible differences, 5% analysed variable. conclude progress date has sufficient importance research therapeutic potential disease.

Obesity and the metabolic syndrome are increasingly prevalent in society their complications response to treatment exhibit sexual dimorphism. Mouse models of high fat diet-induced obesity commonly used for both mechanistic therapeutic studies disease diabetes. However, inclusion female mammals research has not been a common practice, resulted paucity data regarding effect sex on parameters its applicability humans. Here we analyzed male C57BL/6 J mice beginning at 4 weeks age that were placed low-fat diet (LFD, 10% calories from fat), Western Diet (WD, 45% or (HFD, 60% fat). Assessments body composition, glucose homeostasis, insulin production, energy metabolism, as well histological analyses pancreata performed.

Despite their known importance in clinical medicine, differences based on sex and gender are among the least studied factors affecting cancer susceptibility, progression, survival, therapeutic response. In particular, molecular mechanisms driving poorly understood so most approaches to precision medicine use mutational or other genomic data assign therapy without considering how of individual might influence efficacy. The mandate by National Institutes Health that research studies include as a biological variable has begun expand our understanding its importance. Sex may arise due combination environmental, genetic, epigenetic factors, well gene regulation, expression. Extensive occur genome-wide, ultimately biology outcomes. this review, we summarize current state knowledge about sex-specific genetic genome-wide influences cancer, describe response environmental exposures alterations alter trajectory disease, provide insights into integrative analyses interplay genomics cancer. will explore some emerging analytical approaches, such network methods, providing deeper drivers gender. Better these complex interactions improve prevention, treatment, outcomes for all individuals.
