Testosterone

Testosterone is far more than the stuff of the alpha male's swagger. It is present in both sexes and individual levels are correlated with language and cognitive abilities, not just with aggression and sex drive. Testosterone fluctuates according to age and life circumstance, often plummeting at the onset of parenthood, and spiking (for some) during moments of triumph.
