Abstract
A first attempt was made to provide norms for intravaginal pressure in normal women measured by the Kegel perineometer. Data obtained from 78 white females and 64 black females indicate that resting pressure approximates 5 mm Hg, and pressure with appropriate pelvic musculature contracted reaches an average of 15 mm Hg. The difference between resting and contracted pressures is unrelated to the former. There is a moderate negative correlation between number of vaginal births and contracted pressure in the white sample.
