Abstract

A US Census-matched sample of 1,484 subjects aged 20 to 69 from archived data of the Kinsey Institute and current questionnaire plus documentary photo data from 81 new subjects aged 21 to 67 were analyzed to generate a description of penile erections that might act as a useful information base for therapists and others.  Estimates derived from Kinsey data on erections were found to provide a basic foundation of fact, with the current questionnaire/photo analysis implying the need for moderate increases in the Kinsey figures in three areas:  (1) more n-curved (downward curved) erections, about 15% of the total, (2) more erection angles in the lower ranges, with at least one fourth below horizontal, and (3) a greater proportion of shorter erections, with lengths in the 4.5 to 5.75 in. range representing about 40% of the total.

The author of this study has major reservations about both the Kinsey and photo research findings regarding erection length. For a discussion of these concerns click on RELATED ARTICLE.
