What is the sperm competition?

Sperm competition occurs when women with more than one man occur before fertilization before fertilization. A woman has more than one man inside her body, so there is an element of competition between the semen. Each set of sperm travels towards a woman's egg to fertilize, and every man usually wants his sperm to reach the egg first. The behavior of sperm itself does not change during the competition of sperm because they cannot know they are in competition. In this sense, the competition between the sperm of the same man is not considered to be the competition of sperm. Therefore, it will only succeed the most suitable and most physically capable of semen. To help men better in competition with fertilization of women, they developed mechanisms to increase their chances of success. Genrally, the greater the competition between men or the more promiscuous female animal, the more that the development had to play a role in the equipment of the male and its sperm for the task of efficient fertilization.

sperm quality is usually a decisive factor for men's sperm to get sperm competition and fertilize the eggs of a woman. There are several factors that cause male sperm to be better than other men's sperm. These features include longevity, speed and energy.

There have been evolutionary changes in which sperm develops in optimal size to swim as quickly as possible, due to the amount of energy needed to achieve a woman's egg. Men have also evolved to produce sperm in larger numbers where there is more competition of sperm. Large testicles are observed throughout the animal kingdom, where it is so.

As a result of the competition of sperm, the masculine will be a woman in front of other men before and after mating. Some fish, such as Guppies, try to connect with a woman directly after giving birth to ensure that she first friends with her. Men from birds, reptiles and mammals will all fight for the right to contact a woman.

color programs JSOU listed for women where the competition of sperm is great. One example is a colorful peacock that depicts his fans of feathers to impress a woman more than a rival man. Some animals, such as spiders, insert a dome of the dome to the woman after mating to prevent another male to try to connect.

Some women will join with more men in a short time. Black and white Dam-realphally is one such animal. The male of the species has a penis similar to the brushes used to clean the female sperm, which has already been stored inside.
