The research suggests that the men from Britain have bigger penises than those in France, but are less well endowed than Germans.
The average British man’s penis is apparently 5.5 inches when erect - coming ahead of the French at 5.3 inches, Australians (5.2 inches), Americans (5.1 inches) and Irish (5 inches).
British men, who tower over the average manhood in North and South Korea - the smallest in the study at a mere 3.8 inches – came only 78th out of 113 nationalities covered in the study.
The men of Africa’s Republic of Congo are best equipped of all at 7.1 inches.
The sensitive subject has been tackled by Richard Lynn, emeritus professor of psychology at Ulster University.
According to Lynn, the findings confirm previous theories of “race differences in penis length.”
“For most populations penis length are predictable and confirmed,” the Telegraph quoted him as saying.
