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 and construction of nomograms for flaccid and erect 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.
The study concludes shoe size isn’t an indicator of anything other than big feet.
