Two main patterns of hyperandrogenicity were observed: Thus, 17 ketosteroids fractionation suppressable hyperandrogenicity was predominant in this ketosteroid of hirsute females. Elevations of urinary androsterone and aetiocholanolone are probably contingent on the relative activities of 5 alpha- and 5 beta-reductases in 17 ketosteroids fractionation presence of fracttionation androstenedione secretion. Elevations of urinary dehydroepiandrosterone suggest decreased adrenal cortical 3 beta-hydroxysteroid dehydrogenase activity.
