If the male is required to fertilize only one female, and he has no competitors, it is enough to have a limited number of sperm. If the female is called, runs to the side, it is reasonable to have more sperm to increase the chances of successful conception. Therefore, these males, and should have large testicles. As for the gorilla, where a flock of only one male with a slight harem, they do not need large testicles. "
In men, the size of the testicles and a half times greater than that of gorillas, as emphasized by the scientists. This means that people are programmed to the very nature of infidelity. "We can argue until you're blue our loyalty, but solid proof that women will change the men - said the scientist. - Of course, the ladies are not like female chimps 4-5 sexual partners whenever there is a desire to have sex, but almost always have a chance to find some free of boys ready for intimacy.
