British men more well-endowed than French...but smaller than Germans
British men have bigger penises than those in France - but are less well endowed than Germans, research suggests.British men typically have bigger penises than the French - but are less well endowed than German guys, new research claims.
The average British man's penis is apparently 5.5in when erect - coming ahead of the French at 5.3in, Australians (5.2in), Americans (5.1in) and Irish (5in).
And it towers over the average manhood in North and South Korea - the smallest in the study at a mere 3.8 in.
But British men do not have a great deal to shout about in the trouser stakes - coming 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 in.
They are closely followed by Ecuadoreans at 7in, Ghanaians at 6.8in and Colombians at 6.7in.
In Europe, Icelanders are the best endowed at 6.5in and the Irish are the second smallest at 5.03in - behind only Romanians at 5.01in.
Africans have the biggest penises at an average of 6.3in and north-east Asians the smallest at 4.2in.
Brits come in just under the Germans, who are bang on the European average of 5.7in.
The sensitive subject has been tackled by Richard Lynn, emeritus professor of psychology at Ulster University.
He is known for voicing the controversial view that evolutionary pressures have led to racial and national differences in intelligence.
Mr Lynn says that the findings confirm previous theories of "race differences in penis length."
He concludes: "For most populations penis length are predictable and confirmed."
But critics have claimed that Mr Lynn's research is flawed because he has admitted gathering his data on penis length from websites.
Jelte Wicherts, professor of methodology at Tilburg University, Holland, said: "This is a brave paper in a controversial area but the data has no methodology."
The research is published in scientific journal Personality and Individual Differences.
