title: Urinary steroids in men with male-pattern alopecia.
abstract: Enzyme hydrolysis, solid phase extraction, methoxym-silyl derivatization and capillary gas chromatographic analysis were used to examine the changes in urinary steroid metabolites in men with androgenic alopecia. A total of 23 men with androgenic alopecia and 7 age-matched control healthy men collected 24-h urine. Significantly increased values were found in the metabolites of testosterone (T): androsterone (A) (p<0.02), and etiocholanolone (E) (p<0.05) in patients with androgenic alopecia, compared to the control values. Elevated levels of 16-hydroxy-dehydroepiandrosterone (16-OHD) (p<0.03) and cortisol (F) (P<0.05) were found, but the levels of cortisol metabolites were unchanged. Calculating the ratio of total 5 alpha/5 beta metabolites provided information on the activity of 5 alpha-reductase. The ratio of total 5 alpha/5 beta metabolites was increased in the patients showing the increased 5 alpha-reductase activity. The elevated 16-OHD level could be indicative of patients who had mild hyperadrenal activity.
