Just how large is the average penis? The findings of a recently released study has a definitive answer.
The study, "Am I normal? A systematic review andconstruction of nomograms for flaccid anderect penis length and circumference in up to 15,521 men", was published by BJU International in March, and found that an average flaccid penis is 9.16 centimetres (3.61 inches) in length with a girth of 9.31 centimetres (3.67 inches).
The average erect penis measures 13.12 centimetres (5.17 inches) long and 11.66 centimetres (4.59 inches) around.
Researchers compiled data from 17 previously published studies that included information on over 15,000 penises.
According to the study, only 2.28 percent of men have an abnormally small-sized penis.
No correlations between penis size and other body features were discovered, dispelling the myth that you can judge the size of a man's penis based on his shoe size.
