Diagnostic evaluation of hirsutism in women by selective bilateral adrenal and ovarian venous catheterization.
To determine the most significant secretory source of their androgens, 13 hirsute nonvirilized women underwent selective bilateral adrenal and ovarian venous catheterization to obtain effluent blood for the assay of testosterone and delta4-androstenedione. In three patients the testosterone and delta4-androstenedione gradients were significantly greater in the adrenal venous effluents. Testosterone and delta4-androstenedione gradients were significantly greater in the ovarian venous effluents in four patients. In six patients there were no significant differences in the testosterone gradients between the adrenal and ovarian venous effluents. The delta4-androstenedione gradients were greater in the adrenal venous effluents in three of these patients, greater in the ovarian venous effluents in one, and not significantly different in two of these patients. The fact that the measurement of urinary 17-ketosteroid excretion, the suppressibility of peripheral plasma androgens with dexamethasone, and the stimulation of peripheral plasma androgens with human chorionic gonadotropin correlated poorly with the selective catheterization data suggests that the former modalities are imprecise in the diagnostic evaluation of hirsutism in women.
