The developmental processes underlying gonadal differentiation are conserved across vertebrates, but the triggers initiating these trajectories are extremely variable. The red-eared slider turtle (Trachemys scripta elegans) exhibits temperature-dependent sex determination (TSD), a system where incubation temperature during a temperature-sensitive period of development determines offspring sex. ...

Over the past two decades, evolutionary and behavioural ecologists have become increasingly interested in the adaptive consequences of intraspecific variability in life history and behavioural strategies. Recently, behavioural endocrinologists have begun to uncover surprising relationships between levels of prenatal exposure to gonadal hormones and variation in reproductive behaviour in adultho...

The effects of gonadal steroids on neurological well-being and disease constitute a rich and rapidly expanding area of basic and clinical neuroscience. Gonadal hormones exert potent effects on monoaminergic, cholinergic and peptidergic pathways as well as neurosteroidogenesis which, in turn, impact normal brain organization and function. A spectrum of human neurological conditions are influence...

Kidney pathophysiology is influenced by gender. Evidence suggests that kidney damage more severe in males than females and sexual hormones contribute to this. Elevated prolactin concentration common renal impairment patients associated with an unfavorable prognosis. However, PRL involved the osmoregulatory process promotes endothelial proliferation, dilatation, permeability blood vessels. Sever...
