A study of more than 15,500 men has revealed the average penis size, and the results may surprise you.
The research has combined 17 studies with the penis size of of over 15,500 men collected. This showed that the average size of an erect penis is 13.12cm (5.16 inches), and 9.16cm (3.6 inches) when flaccid.
The results go against the widely accepted norm of 15.24cm (6 inches).
As well as length the researchers looked at thickness (girth), with the average erect penis being 11.66cm (4.59 inches ) and 9.31cm (3.66 inches) when flaccid.
Psychiatrists involved hope that their findings would help those who suffer from “small penis anxiety”, or those who may be worried that they measure in smaller than average.
