Features 
Description Testosterone, (17-Hydroxy-4-androstene-3-one), a C19 steroid, is one of the most potent naturally secreted androgens [1]. In postpubertal males, testosterone is secreted primarily by the testes with only a small amount derived from peripheral conversion of androstenedione [2]. In adult women, it has been estimated that over 50% of serum testosterone is derived from peripheral conversion of androstenedione secreted by the adrenal and ovary, with the remainder from direct secretion of testosterone by these glands [2,3]. The majority of circulating testosterone is bound by SHBG and a smaller portion is bound by albumin. Only 1-2% exists in circulation as unbound or free testosterone [4].

In males, testosterone, either directly or after conversion to DHT, normally functions in fetal Wolffian duct differentiation, development of male external genetalia, stimulation of spermatogenesis, stimulation of anabolic activity in a variety of tissues and, possibly, behavioral and psychological effects [5,6]. In both sexes, testosterone contributes to the development of secondary sexual hair, acne, and scalp hair patterns. In prepubertal males, elevated testosterone levels are found in precocious puberty [7] and in androgen receptor defects [5]. In adult males, low testosterone levels are associated with various pathological conditions, including primary hypogonadism. In females of all ages, elevated testosterone levels can be associated with a variety of virilizing conditions, including adrenal tumors and polycystic ovarian disease [3].
