Testosterone is the primary sex hormone in men. It performs a vital function in regulating male sex drive, bone mass, fat distribution, muscle mass, and the production of red blood cells and sperm. Women also have testosterone, but in much smaller amounts. This article focuses on the measurement of testosterone in adult men.

Most testosterone circulating in the bloodstream is bound to either Sex Hormone-Binding Globulin (SHBG) or albumin, the main protein in blood. Only a small percentage (2-3%) is immediately available to target tissues as free testosterone.
