Testosterone is the prototypic and predominant circulating androgenic steroid. It plays a major role in the growth and function of many reproductive and non-reproductive tissues and organs including muscle, liver, and brain, directing the development of the male phenotype during embryogenesis and at puberty. Testosterone is synthesized from 17α-hydroxy progesterone by the enzymes 17,20-lyase and 17β-hydroxysteroid dehydrogenase in the gonads of both males and females. In many target cells it is reduced to 5α-dihydro testosterone, which mediates many of the biological actions of testosterone. It is then further metabolized to 17β-estradiol by aromatase.1 Serum levels of testosterone range from 0.5 ng/ml in women to approximately 6-10 ng/ml in men, declining with age.2
