Sexual dimorphism consists of phenotypic distinctions between one sex and another. These distinctions can include physiological and behavioural differences. Uncover the latest and most impactful research in Sexual Dimorphism. Explore pioneering discoveries, insightful ideas and new methods from leading researchers in the field.
Freshwater fishes are very sensitive to changes in their environment, especially in fragile ecosystems of the Himalayas in their reproductive patterns. This is a comparative study of reproductive biology of three sympatric snowtrout species,...
In forensic investigations of skeletal remains, age and sex estimation are crucial for identification. This retrospective study evaluates anthropometric measurements, fusion degrees, and radiodensity of the hyoid bone in a large sample. It analyzed...
Background We aimed to develop contemporary reference values among recreationally trained and strength-interested individuals for the squat, bench press, and deadlift, and describe sex- and age-related patterns in estimated relative strength....
Purpose The lateral femoral wall serves as a critical determinant of intertrochanteric fracture stability, internal fixation strategy, and postoperative clinical outcomes, and has emerged as one of the core research focuses in orthopedic trauma....
Background The environmental conditions in which holometabolous insect larvae develop influence many aspects of their life-history traits in adulthood. In the context of vector control programs, understanding how environmental factors affect larval...
Epigenetic regulation of sexual development is widely documented in model species, yet data for commercial invertebrates remain limited. Here, we used whole-genome bisulfite sequencing (WGBS) to profile genome-wide DNA methylation and identify...
Pejerrey (Odontesthes bonariensis) exhibit thermolabile sex determination (TSD). Because most studies use constant temperatures, we tested how diel temperature fluctuations (± 2 °C around means of 19, 24, and 28 °C) and chronic hypoxia (~ 4 mg O₂ L−1...
Although sex differences in suicidal behavior among young patients with major depressive disorder (MDD) are well documented, whether the association between elevated body mass index (BMI) and suicide attempts (SA) varies by sex remains inconclusive....
Black women sit at the intersection of sexualized gender and racial oppression which shapes how Black women are socialized and influences how their images are (mis) represented in the media. Guided by sexualization scholarship, the critical media...
Background Posterior tibial slope (PTS) affects sagittal knee biomechanics and is relevant to ligament reconstruction, osteotomy and arthroplasty. Published values vary with population and measurement method, and data from Jordan are lacking. This...
Pornhub Insights (2025) reported that Japan ranked 11th worldwide in total traffic, indicating widespread use of adult videos (AV). Existing research has primarily focused on AV-related harms from expert and Western perspectives. Few studies examine...
Background World Health Organization (WHO) growth standards support comparable screening and surveillance, but a z score is not an etiologic diagnosis. In Wayuu children, interpretation occurs amid nutritional deprivation and barriers to care. This...
Background The sex distribution of newly diagnosed HIV patients shows substantial geographical heterogeneity worldwide. While more than 60% of new patients within sub-Saharan Africa are women and girls, men constitute the majority of notified...
Sex differences in adipose tissue vascular remodeling critically influence susceptibility to obesity-associated metabolic disease, yet the underlying mechanisms remain unclear. Here we identify Forkhead box O1 (FoxO1) as a sex-dependent regulator of...
Background Functional performance test (FPT) results have rarely been analysed for sex-specific differences among professional ballet dancers yet. Therefore, this study aims to assess the FPT results of professional female and male ballet dancers,...
If traits of individuals are associated with occupational choice, sex differences in those traits should be associated with sex differences in occupational choice, and consequently, with occupational sex segregation. In this cross-sectional study,...
Background The Neotropical armored catfish genus Harttiais an exceptional model for studying sex chromosome evolution, as it harbors the highest diversity of multiple sex chromosome systems known among fishes. However, the evolutionary history of...
Background Sex-specific disparities in aortic intramural hematoma (IMH) remain inadequately characterized. This study aimed to investigate the impact of sex on clinical outcomes of type A and type B IMH. Methods A total of 1,590 patients with IMH...
Circadian disruption is a known driver of multisystem pathophysiology, yet how it interfaces with the gut microbiome and systemic metabolism across the life course, and how these interactions are shaped by biological sex, remains poorly defined. We...
Abstract 17β-Hydroxysteroid dehydrogenase type 5 from Mus musculus (17β-HSD5Mm) performs preferential NADPH-dependent conversion of androstenedione (AD) into testosterone (T). Unlike the well-characterized 17β-HSD types 1, 2, 3, 4, and 7, which...
