Hormones and neurological pathways must be in sync for sexual desire to be present. Blood vessels, nerves, and penile integrity must all be present for an adequate erection and its maintenance during the sexual relationship.

Relating sex-bias in human cortical and hippocampal microstructure to sex hormones Here, the authors demonstrate that cortical microstructure in young adults shows marked sex bias, which is most pronounced in paralimbic areas. The effects are put into context with variations in sex hormones and loc...
