Vaginal sensitivity to electric stimuli: theoretical and practical implications.

Vaginal sensitivity was investigated in a group of 60 volunteers by means of an electric stimulus and under nonerotic conditions. In comparison to the dorsum of the hand, the genital area has a low sensitivity for electric stimuli (p less than 0.001). Of the genital area, the vaginal wall measured 2 to 4 cm from the vaginal introitus was found to be very insensitive (p less than 0.05). Within the vaginal wall a relatively sensitive position to electric stimuli could be detected at the "12-hr position" (the anterior vaginal wall) (p less than 0.001). The study provides data underscoring previous anatomical and clinical research findings regarding the sensitivity of the anterior vaginal wall. The inefficiency of coitus for inducing female orgasm is discussed.
