Sexual inactivity results in reversible reduction of LH bioavailability [PDF]

open access: yesInternational Journal of Impotence Research, 2002
We have recently documented significantly reduced serum testosterone (T) levels in patients with erectile dysfunction (ED). To understand the mechanism of this hypotestosteronemia, which was independent of the etiology of ED, and its reversibility only in patients in whom a variety of nonhormonal therapies restored sexual activity, we measured serum ...

Rapid evolution of sex pheromone-producing enzyme expression in Drosophila. [PDF]

open access: yesPLoS Biology, 2009
A wide range of organisms use sex pheromones to communicate with each other and to identify appropriate mating partners. While the evolution of chemical communication has been suggested to cause sexual isolation and speciation, the mechanisms that govern
