Roughly half the world has one, and that means roughly half the world probably wonders how his compares to the norm. New research on penis size may shed light on what's "normal."
There is now a formal review of research on the average penis length. British investigators reviewed 17 published studies, consisting of over 15,500 men who had their penises measured by health professionals.
According to this study, the average length of a flaccid penis was 3.6 inches, a flaccid stretched penis was an average of 5.3 inches, and the average length of an erect penis was 5.2 inches.
Dr. David Veale, of King's College London, said in a press release that the data “will help doctors reassure the large majority of men that the size of their penis is in the normal range.”
Dr. Veale and team also said that the findings will help investigations into a possible link between condom failure and penis size. There hasn't been extensive research into the relationship between these two variables, but researchers hope their findings will spark more study on the topic.
This study was nine pages long, if you're wondering, and it was published online March 3 in the journal BJU International.
