Research on average penis size has confirmed racial stereotypes, with Africans coming out on top, Asians at the bottom and Europeans somewhere in between.
Richard Lynn, emeritus professor of psychology at Ulster University carried out the research, which is published in the scientific journal Personality and Individual Differences.
113 nationalities were included in a study of average penis lengths.
In the penis size league tables the Daily Mail reports that men from The Republic of the Congo take top position with a porn star like 7.1 inches, with the Ecuadorians, Ghanaians and Columbians not far behind with 7 inches, 6.8 inches and 6.7 inches respectively.
The average for the African continent as a whole is a whopping 6.3 inches.
The Icelanders come top of the Europeans with 6.5 inches.
The Germans are Mr European average with 5.7 inches.
The Brits come out above the French, beating the more traditional country of love and romance, by a full 0.2 inches.
The Brits also beat the Australians (5.2in), Americans (5.1in) and Irish (5in).
At the other end of the table, North and South Korea measure in at 3.8 inches. India and Thailand are only slightly bigger at 4 inches.
The overall average for north-east Asians was the lowest at 4.2 inches.
How reliable are these figures?
According to The Telegraph critics have claimed that Mr Flynn’s research is flawed because the penis length data was gathered from websites.
The Telegraph quotes Jelte Wicherts, professor of methodology at Tilburg University, Holland as saying, “This is a brave paper in a controversial area but the data has no methodology.”
Some of the average penis sizes by country:
Republic of Congo, 7.1
South Africa 6
New Zealand 5.5
South Korea 3.8
North Korea 3.8
