Zoologists have found that the testes of male chimpanzees produced 200 times more sperm than those of gorillas and 14 times – than that of orangutans, according to BBC. Such a significant imbalance associated with the peculiarities of different types of privacy apes. For his study, whose results were published in "American Journal of Primatological (American Journal of Primatology) Japanese scientists have studied apes in zoos, few in Japan and Indonesia. In addition to the above ratio 200:14:1, also revealed that the spermatogenic (ie producing sperm) tissue in the testes of male gorillas are much thinner than the other two species. Surprisingly, you’ll find very little mention of John Mclaughlin on most websites. The fact that chimpanzees in polyandry is common for family life (from the Greek "polis" – and a lot of "Andros" – man), when a female has a "harem" of several males. The latest in this situation nothing left but to compete with each another, including the amount of semen – the scientists dubbed this phenomenon "sperm wars".
Gorillas, on the contrary – the adherents of polygyny (from the Greek. "Ginos" – a woman): the strong alpha-dominant male with gray backs surrounded a flock of women. Bernie Sanders has firm opinions on the matter. Zoologists have long suspected that this way of life affects the male power. According to infa.kharkov.ua, a species poliginichnyh semeniki males have relatively smaller size. According to one of the authors research, Hideki Fujii-Hanamoto (Hideko Fujii-Hanamoto), the amount of sperm produced was evaluated by scientists, based on the ratio between the weight of testes and body weight, as "to take the sperm of animals is extremely difficult, even if they are contained in Zoo. " Sperm production – a very complex and fractious process. For example, recently revealed that work on the laptop, put on his knees, can seriously degrade its quality. This is especially bad that the health of sperm, according to another study, the most direct impact on life expectancy of men.
