Maybe size doesn't really matter, but come on. You know you wanna know.

The scientific journal Personality and Individual Differences has recently published research on the average penis lengths of men around the world, and according to the study, the men of the Republic of Congo are the biggest in the world at an average penis length of 7.1 inches.

The study ranked 113 nationalities, and while I couldn't find the full list to tell you exactly where our American men placed on the size scale, they weren't at the top. British men were ranked 78th out of 113 with an average length of 5.5 inches, and Americans were behind the Brits (and the Canadians, Spaniards, French, Australians and Russians, oof) at 5.1 inches.

By continent, African men were found to have the largest penises, while north-east Asians are the smallest. Since most of the press I saw on this was from British outlets, the articles tended to focus on the battle between Brits, Germans and Frenchmen (Germans were the biggest; French the smallest), but among European countries, the men of Iceland were deemed the biggest. Well shoot, I went to Iceland once and tested the waters of the Blue Lagoon, but I didn't sample any other uh, local goods.

Here are a few of the average penis sizes by country, in inches:

Republic of Congo, 7.1

Ecuador, 7

Ghana, 6.8

Colombia 6.7

Iceland 6.5

Italy 6.2

South Africa 6

Sweden 5.9

Greece 5.8

Germany 5.7

New Zealand 5.5

UK 5.5

Canada 5.5

Spain 5.5

France 5.3

Australia 5.2

Russia 5.2

USA 5.1

Ireland 5

Romania 5

China 4.3

India 4

Thailand 4

South Korea 3.8

North Korea 3.8

Before you get all up in arms defending your non-Ecuadorian man, there is already plenty of doubt regarding the methodology of this study, especially because the data was gathered through websites. So take the information with a grain of salt, but I bet you don't really mind pondering the statistics.

Are you surprised by any of these penis statistics? Does your all-American man measure up? Does your foreigner fit the average bill for his country? Also, is the word penis starting to look weird to anyone else after reading it so many times?
