Men With Large Testicles May Be More Likely To Cheat, So Pay Attention to What's Going On Down There

According to recent research by Norwegian scientists at the University of Oslo, there is a correlation between testicle size and the likelihood of infidelity. The scientists found that primates with larger testicles were the ones more likely to cheat on their partner. Petter Bøckman, Assistant Professor, told The Telegraph that it all comes down to natural selection.

We can determine the degree of fidelity in the female by looking at the size of the male’s testicles. The less faithful the female, the larger the male’s testicles.

"If the male will only fertilise one female and has no competitors, he only needs sufficient sperm to reach the egg. If the female mates on the side, it is smart to have as many cars as possible in the race.

"Then, the male must have testicles that are as large as possible."

Bøckman goes on to add that human testicles are one and a half times larger than those of gorillas and this research shows that by nature females may cheat. Not that this is good or bad news for the human race, but it certainly does put our behaviors and motives into perspective. Now, excuse me while I try to finish my lunch.
