Wondering how you and your country measure up?

The United States came in at 5 inches; Australia came in at 5.2 inches. At the top of the list were the Congo, whose men boasted an average of 7.1 inches. Closely following them were Ecuadorians at 7.0 inches, Ghanaians at 6.8 inches;and Colombians at 6.7 inches.

In Europe, Italians were at the top of the list, with 6.2 inches. Next was Greece, at 5.8 inches and Germany at 5.7 inches. Britons measured in at 5.5 inches, beating out the French, who measured 5.3 inches. Rounding out the list were North and South Korea, who both measure, on average, 3.8 inches.

But the study is not without its share of controversy – and not just because of the subject matter itself.

The paper was written by Richard Lynn, who mainly based the information from his study on a website. The website had ostensibly collected data on penis size from 113 countries, but it had not been verified by academics. Lynn is a professor emeritus at Ulster University in Northern Ireland and is a controversial figure in science, particularly due to his thesis which claimed that certain races have evolved to be more intelligent than others.

Jelte Wicherts, a professor of methodology at the Netherlands’ Tilburg University, said to The Sunday Times, “This is a brave paper in a controversial area but the data has no methodology and Lynn’s paper should not have been published.”

Penis size seems to be a bit of a preoccupation for men, causing a healthy industry that claims to have various methods of enlarging the male organ. Interestingly though, there is a significant number of men who claim to have small penises but are in fact quite normally endowed. Penile enhancements can come with a host of complications and side effects.

Richard Lynn’s study will be published in the journal Personality and Individual Difference.
