Average Penis Size Studies

A number of studies have been conducted on penis size with results varying depending on the mode in which information was gathered. These modes vary from self-measure, to assisted measure; statistics indicate that assisted measurement numbers are indeed slightly larger than the self-measure technique. The results have also concluded that the mean penis size is slightly larger than the median penis size, meaning that the average size is not necessarily in agreement with the middle value of the data sets.

The following tables summarize the concluded average penis size from a number of conducted studies.

Measurement Technique

Measurement technique is usually a point of discussion when attempting to find a true average. In most cases, assisted assessment of penis size was utilized - as such, there should be a light pressure implemented on the pelvic bone slightly pushing in any surrounding tissue. It is important to maintain a light pressure during measurement.
