Testosterone is a hormone produced in the testes (in men) and ovaries (in women). Men produce about thirty times more testosterone than women.

- Determines the physical and behavioral characteristics of men: strengthening of bone structure; voice thickening at puberty; increased muscle mass; hair formation and maintenance (eg beard); maturation of sexual organs, activation of brain areas responsible for sexual desire.

Excess and Decrease

- In excess, testosterone can make women and men more aggressive and egocentric.

- In low amounts, men may have decreased sexual desire.
