The clitoral index: a bioassay of androgenic stimulation.
The glans clitoris is a target organ that is responsive to androgenic stimuli and enlarges throughout life. The size of the glans clitoris can be quantitated by determining the clitoral index (CI), which is the product of the sagittal and transverse diameters of the glans. Four hundred ten patients, ranging in age from 17 to 35 years, were examined. Ninety-five percent of 249 normal women had a CI less than 35 mm2. Of 85 patients with clitoromegaly (CI greater than 35 mm2) in addition to at least 1 other clinical sign of excess adrogenic stimulation, 53 (62%) had abnormally high values for either or both total serum testosterone and 17-ketosteroid levels. The CI is a useful bioassay for the clinical recognition of excess androgenic stimulation.
