testosterone

Testosterone is a hormone made in the testes in males and in the ovaries in females. Testosterone is generally found in greater amounts in males, where it aids in the development of the male sex organs and sperm.

The word testosterone was coined in the 1930s. It is based on the Latin word testis, which means testicle, and the word sterol, meaning steroid. Because it is the hormone that develops male characteristics, the word testosterone sometimes refers to the quality of being male. A room crowded with men watching football is commonly described as being "full of testosterone."
