Testosterone Test

Testosterone is an androgen, or a sex hormone, produced by both males and females. It plays a role in puberty and fertility. It also affects sexual desire.

In males, the testes produce most of the testosterone. In females, the production of testosterone occurs mostly in the ovaries. Males have higher levels of testosterone than females. Doctors believe that testosterone has a significant influence on the development of many traits, including:

• increased muscle bulk
• higher bone mass
• physical strength
• body hair

However, the hormone plays an important role in women as well, including their reproductive health and the ability to feel sexual arousal.
