Site of male sexual desire uncovered in brain

(Northwestern University) The locus of male sexual desire has been uncovered in specific regions of brain tissue where a key gene named aromatase is present, reports a new study in mice. The gene regulates sexual behavior in men, and thus can be targeted by drugs to either increase its function for low sexual desire or decrease its function for compulsive sexual desire, scientists said. Aromatase converts testosterone to estrogen in the brain, which drives male sexual activity.
