There are more alarming information about the decline in the number of sperm in the man. In 20 years, a decrease of 40 % would have been recognized, compounded by a decline in quality. Some researchers in make an issue as important as the warming of our planet.

Causes many

In head, the pollution. We live surrounded by chemicals. The toxicity of phthalates on the germ cells, which constitute the precursor of the spermatozoa, is no longer to demonstrate. As well as that of pesticides, which also contribute to the alteration of the sperm.

The power is in the collimator, as well as alcohol and tobacco, which are without a doubt the main causes. Smoking will lead to the destruction of the blood vessels of the genital tract of men. At the level of the penis, this is responsible for an alteration of the quality and the duration of the erection. At the level of the testes, vascular alterations lead to a destruction more or less irreversible for the production of sperm.

The testicles need to stay cool

It was also referred to the heat, because the production of sperm is a phenomenon extremely sensitive to the temperature. The sperm must be maintained at a temperature between 33 and 34 °C. As a function of temperature, the scholarships contract or relax so as to maintain this temperature constant. This is also the reason why they are on the outside of the body !

An increase of the testicular temperature results in a slowdown or even a stoppage of spermatogenesis. It is from this finding that one has accused the jeans that are too tight. Some have blamed the stress, which our modern world is customary, but then, it would still be necessary to demonstrate that our modern life is more stressful than contemporary wars, and famines…

The sex said ” low ” is the strongest

One might finally mention the actual concerns on the future of our Y-chromosome passed from father to son and that is the main difference between the man and the woman. XX, it is female ; XY is a man. It was the order of things since the dawn of time… But, here it is, the future is not rosy. Or rather, he is too.

The man is in danger of extinction because the Y chromosome is a true ruin that did not stop losing its genes over millions of years of existence… Thus, the X chromosome, which is 80 times larger than the Y chromosome, also contains 500 times more genes.

The male is an imperfect combination. Take the woman. With its two X’s, one may at any time fix the other. While in humans, the X and the Y are left to fend for themselves in the event of a change. Lack of ability to self repair with a chromosome partner, degenerates, and some predict that its elimination, by less than 200 000 years. Even there, the interpretations vary… as a team of researchers in the us are very serious talks about it, tens of millions of years.

This gives a little bit of time to research. But here, too, the first experiences are not going in the right direction. It is the woman who gives birth to the man. Nothing that this argument would have had to think about the male race. The researchers are aware, by mixing two eggs, give birth to a mouse inheriting from each of the mothers. Of course, this offspring is exclusively female.

The woman is not only the future of Man. It can happen to him, and by his genetic heritage, which holds the future of all mankind…
