Abstract

Female orgasmic capacity was previously shown to vary significantly with the condition of the pubococcygeus muscle as evaluated by an extensive digital examination and readings from a perineometer, a pressure sensitive device inserted into the vagina. Subsequently, a discriminant analysis was applied to 6 types of perineometer readings to determine if an optimal combination of readings could alone serve as an accurate evaluation of muscle condition. Initial strength resting and initial strength contracting predicted "good" versus "bad" muscle with 73.4% accuracy. A nomogram is presented for clinical use.
