Men will create two sperm. One of the sperm is to make the eggs conceive. They will constantly rush forward in a brief life until they find an unsteady egg.The other purpose is to defeat sperm from other men.
Male manufacturing sperm with different functions
Among the men who have been tested, men who are tired of fixed partners in the day and night are about 3.98 billion sperm in the body; about 5 % of men with only 5 %.The number was 7.1 billion, almost doubled.In addition, the number of sperm in men who only have sex with fixed partners is obviously less than men who like early adopters.
These researchers said that men would create two sperm. One of the sperm was to conceive the eggs. They would keep rushing forward in a brief life until they found an unsophisticated egg.The other purpose is to defeat sperm from other men.
"Competitiveness of sperm" originated from animal nature
The change of sperm number is called "the competitiveness of sperm."In the subconsciousness, men are looking forward to "sex" can change thousands of, and they are diverse.Therefore, the less contact with sexual partners, the lighter understanding, the more you can arouse the sexual desire of men.When foreign stimulus affects sexual psychology, it arouses the sexual desire of men, and the number of sperm will increase.This research also uses other primates, such as orangutan, ape monkey, etc., and the results are very similar.
One of the researchers said: "This study reflects human monogamous monogamy." The researcher believes that animals will be attracted by fresh things, and this fresh stimulus will also produceThe larger response increases the number of sperm.This is why you get along with fixed partners for a long time will reduce the number of sperm.However, the results of this study were also questioned by many experts. They believed that this was just an excuse for men to "go to the wild food", and it would cause the proliferation of sexual diseases.
Therefore, these experts suggest that if you want your own mouth, you do n’t go outside to mess with flowers, and make them “sex” to “sex”. Women itself is best to keep “freshness” and from time to time.happy.
