The possible relationship between plasma androgenic activity and acne vulgaris was investigated. Plasma testosterone and sex hormone binding globulin (SHBG) levels were determined in healthy girls during different stages of puberty, in healthy adult women and in women with acne vulgaris. Testosterone increase during puberty, whereas SHBG decreased during the early stages before it increased and stabilized plasma concentrations of testosterone and SHBG. Women with severe acne vulgaris had testosterone levels in the same range but the SHBG levels were significantly lower than those of healthy women and women with mild acne. These results show a high androgenic activity in the intermediate stages of puberty, when acne vulgaris is a common complaint and an increased androgenic activity in adult women with severe acne vulgaris.
