One difference between the glans penis and the glans clitoridis is that the glans clitoridis packs nerve endings into a volume only about one-tenth the size of the glans penis. Therefore, the glans clitoridis has greater variability in cutaneous corpuscular receptor density (1-14 per 100× high-powered field) compared with the glans penis (1-3 ...
Sexual differentiation includes development of different genitalia and the internal genital tracts and body hair plays a role in sex identification. [ 2 ] The development of sexual differences begins with the XY sex-determination system that is present in humans, and complex mechanisms are responsible for the development of the phenotypic ...
One cross-cultural survey comparing body-mass preferences among 300 of the most thoroughly studied cultures in the world showed that 81% of cultures preferred a female body size that in English would be described as "plump". [240] Availability of food influences which female body size is attractive which may have evolutionary reasons.
According to a recent TODAY/AOL body image survey, when it comes to physical imperfections, adult men and women worry most about 23 specific body parts. Perhaps most surprising of all, the body ...
Researchers at the University of Toronto say that differences between men and women on some tasks that require spatial skills are largely eliminated after both groups play a video game for only a few hours.
