Site of male sexual desire uncovered in brain:
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 Northwestern Medicine study in mice.
[...] "This is the first key finding to explain how testosterone stimulates sexual desire," said senior author Dr. Serdar Bulun, chair of obstetrics and gynecology at Northwestern University Feinberg School of Medicine and Northwestern Medicine. "For the first time, we demonstrated conclusively that the conversion of testosterone to estrogen in the brain is critical to maintain full sexual activity or desire in males. Aromatase drives that."
When Northwestern scientists knocked out aromatase selectively in the brain, sexual activity in male mice decreased by 50%, despite their having higher levels of blood testosterone levels (compared with control male mice).
If a normal male mouse is put with a female one, Bulun said, "it would chase after her and try to have sex with her. If you knock out the aromatase gene in the brain, their sexual activity is significantly reduced. There is less frequency of mating. The male mice are not that interested."
The finding can contribute to new treatments for disorders of sexual desire, the scientists said.

You have obviously never been to court.
