The number of sperm released during ejaculation a man lost a lot of other mammalian species. Sperm production is only able to surpass rats and guinea pigs, even losing a lot of pigs are smaller than humans. Mammalian species can be equated with human beings in relation to sperm production is a rabbit. Long-eared rodents are able to spend the same amount of human sperm that is 280 million in a single ejaculation. Other mammals larger than rabbits are generally issued in a matter of billions of sperm, rather than hundreds of millions just like humans. Sheep spend 1 billion sperm once ejaculated, while most of the pigs 8 billion. More, comparison of the number of sperm in the ejaculate once in humans and several species of mammals or mammals are as follows, as quoted from Oakland.edu, Thursday (26/05/2011).Sperm
- Pigs (8 billion)
- Cows (3 billion)
- Sheep (1 billion)
- Human (280 million)
- Rabbit (280 million)
- Guinea pig (80 million)
- Sewer rat (58 million)
- The house mouse (50 million)
The number is certainly only an average is taken because in fact the production of sperm in humans varies greatly.The number of sperm produced is influenced many factors including diet, lifestyle and the frequency of male ejaculate. The ejaculate, semen is ejected by the male genitalia vary between 2-6 ml with an average of about 4.2 ml or approximately equivalent to 1 teaspoon. 280 million figure is obtained based on the average amount that is 66 million sperm cells / ml. In men, sperm production is reduced globally in recent decades. The figure of 66 million / ml is the result of research conducted in the 1990s, while in the 1940s, the number of male sperm cells still reach 113 million / ml. The more sperm are produced and released during ejaculation, the higher the man's ability to fertilize his partner. But do not worry, men with sperm concentrations of only 20 million / ml can still fertilize a smaller chance though because it takes only one sperm actually.
