The origin of human beings was evolved from ape monkey, and everyone must know about evolution theory.Today's environmental changes have caused men to be affected by infertility diseases, and some people's sperm has evolved.These evolved sperm are even more amazing in terms of speed and power, and the fertilization of sperm eggs has also been destroyed.Scientists call it "super sperm."
So, let's take a look at the research of experts!
Scientists have discovered that human sperm has a unique "gene signature", as if a key, which can open the lock of pregnancy in the egg.Ellen Harson, a evolutionary biologist at the University of Tel Aviv University, believes that male infertility rates have risen so high that they will not be purely three factors: living pressure, disease infection and environmental pollution.According to the fertilization rate data and mathematical models, he inferred that some of the sperm of some infertility men are not only not strong enough, but have amazing speed and power. It is particularly easy to break through the line of defense in women and penetrate the eggs.
Sperm's arms evolutionary theory
Biologist Olen Harson believes that it is only a tense lifestyle, disease infection and pollution that cannot explain the high incidence of infertility.His research shows that the incidence of infertility is generated by the "Evolution Military Reserve Competition". In the "Evolution Military Competition", in order to improve reproductive ability, the body of men and women has undergone subtle changes.If the body of both men and women evolves at the same time, it is beneficial to productivity.However, if the pace of both parties is inconsistent, what is brought about is trouble.Researchers say: Sometimes high infertility rates occur during coordination.This may be the reason why it is difficult to explain for decades.
This theory of Hason is based on reproductive statistics and mathematical models. He said that the current sperm swimming speed is so fast, so that they can cross this blockade and destroy the normal fertilization process.At the same time, due to stress or pollution, the probability of defeating the female reproductive tract with weaker sperm to defeat the barrier of the female reproductive tract is even smaller.
Super sperm destroys strong or can cause infertility
Because the destructive power of the super sperm is too strong, they often cause the phenomenon of "polyspermy", which makes it difficult for the eggs to be fertilized.The reproductive system of men and women has always carried out subtle evolution to improve fertility.Women gradually increase the biochemical defense of sperm, discharge more sperm, dilute, and kill, and to increase the threshold of "sperm", and men will enhance the power of sperm; Line.If the gender is consistent in this regard, the success rate of egg fertilization will increase; the fertility rate at the end of the twentieth century is long -term high, perhaps because of this.If the gender is not coordinated in this regard, the combination of essence will be damaged.
