Timing is everything when trying to land a mate. In many species, female receptivity tomale sexual advances is synchronized to fertility and is mediated by steroid hormones produced in the gonads, such as oestrogens. How these hormones tune neural circuits to transition females to mate-seeking mode is unclear. In a series of elegant experiments, neuroscientist Jenna McHenry and colleagues in Ga...

There is good evidence for gender-specific differences in asthma regarding all affected areas, from intra- to extra-cellular mediators to the whole organ structure und functioning of the lung. These result from complex, in parts synergistic, in other parts opposing, effects - especially of female sex hormones, and rather protective effects of male hormones against asthma, which include effects ...

The female reproductive system consists of two ovaries, two fallopian tubes, the uterus, cervix and external genitalia. Every female undergoes a monthly cycle of 28 days, in which an egg is released from either ovary and the lining of the uterus is prepared for the implantation of an embryo, which eventually sheds off in case fertilization does not occur. This normal physiological mechanism is ...

Sex differences in basal extracellular striatal dopamine concentrations in gonadectomized male and female rats have been reported previously. In the current experiment, estrous cycle-dependent variation, sex differences and the effect of gonadectomy on extracellular striatal dopamine concentrations were determined using quantitative microdialysis. Female rats were found to have significantly hi...

Renal functions are regulated by steroid sex hormones, but the exhaustive identification of their receptors along the nephron is still lacking. Here, we have localized all known nuclear or membrane-bound sex hormone receptors and some of their activators along the nephron of male and female mice. Almost all receptors are present in male and female kidney, some of them having very restricted loc...

The physiological significance of hormonal changes in early postnatal life is emerging, but the behavioral significance in humans is unknown. As a first test of the relationship between hormones and behavior in early infancy we measured digit ratios and salivary hormone levels in forty-one male and female infants (3-4 months of age) who watched a video depicting stimuli differentially preferred...

BACKGROUND Asparagus is a plant with high nutritional, pharmaceutical, and industrial values. OBJECTIVE The present study aimed to evaluate the effect of aqueous extract of asparagus roots on the hypothalamic-pituitary-gonadal axis hormones and oogenesis in female rats. MATERIALS AND METHODS In this experimental study, 40 adult female Wistar rats were divided into five groups, which consist...

Sex role orientation, i.e., a person's masculinity or femininity, influences cognitive and emotional performance, like biological sex. While it is now widely accepted that sex differences are modulated by the hormonal status of female participants (menstrual cycle, hormonal contraceptive use), the question, whether hormonal status and sex hormones also modulate participants sex role orientation...
