The average girth is 3. Girth is the circumference of the penis at its widest section. The BJUI research used data from 17 studies, and the study participants totaled more than 15, men.

Published today in the British Journal of Urology International , their new study synthesizes data from 17 previous academic papers that included measurements from a total of 15, men from around the world. The data enabled the researchers to calculate averages and model the estimated distribution of penile dimensions across humanity. The corresponding girth measurements are 9. A graph of the size distribution shows that outliers are rare. A cm 6. Conversely, an erect penis measuring 10 cm 3.
