Bigger Testicles in Men means Greater Infidelity - New Shocking Research

A scientist at the University of Oslo has discovered, that there is a correlation between infidelity and the size of a male's testicles.Researchers found that primates with bigger testicles were more likely to be unfaithful.Petter Bøckman, Assistant Professor, said:"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." According to the professor, as, for example, in gorilla troops there is only one male, gorilla male doesn't need large testicles - that is why they are tiny. Meanwhile bonobos have large testicles and mate in large groups, the scientist revealed.The testicles of humans are one and a half times larger than those of gorillas.Prof Bøckman said: "This testifies with abundant clarity to life in our flock. We can pledge our fidelity until we are blue in the face, but this is evidence that our females are cheating. We are not like chimpanzees, where the female has four or five sexual partners every time she is in heat, but there is always a certain likelihood that the neighbouring male has dropped by." What is more, it has been discovered in the course of the research that the testicles are also large in animals that have sex with many females. For example, lions have big testicles because all the females in the pride "must have sex at the same time". Thus, one lion must mate with all the females every half-hour within the period of 3 days.
