Extinction of men - The worry of mankind

Nam Ngu (According to Onet.pl)

According to scientists' research: genes specific to ' men ' are being degraded strongly. They warned that in the future, men will become extinct. Time is determined to be about 125,000 years later, less than 5,000 generations! Many sperm banks have been established worldwide. But can this risk be saved?

The nature of men is . very weak

It is well known, the chromosome (chromosome) Y in the cell nucleus decides that the baby will be a boy. Women in identical nuclei of the X chromosome are identical. You can call it a master copy and a copy to make it safe because if one missed something, then there was one instead. In men, only one piece of Y chromosome is short and isolated. This poor piece of baby is only 1/50 the size of a whole gene, so it has almost no strength and no reproductive ability at all.

In addition, to fertilize an egg, millions of sperms must be mobilized. We try to do calculations: all men in the world ' fight ' about 50 billion times a year, meaning that about 1 million liters of sperm are consumed every day, ie about 200,000 billion sperms are made in a second. As a result, humanity developed 5 new members, in order to achieve that achievement, women all over the world only had to release 400 egg cells! Why is creation so wasteful? Why is there this injustice! While the beauty only needs to spit out an egg cell, do men have to "create" a huge amount of sperm? The reason for most scientists is that they are not really as powerful as the names people use to call their owners: men!

The quality of ' breeds ' is on the decline

According to geneticists, the sperm's biological status is getting worse and worse, including the decline in quantity and quality.

In 1992, the endocrinologist Skakkeback (Denmark) summarized the sperm count in 15,500 men in 20 different countries from 1938-1990: the number of sperm after 50 years has decreased by almost half ( from 113 million / ml to 66 million / ml). In France, only studying donor sperm, they also found that each year, the number of sperm decreased by 2% (89 million / ml in 1973 to only 60 million / ml in 1992).

The alarming findings of British geneticists show that the male chromosome of men today is only one-third the size of the Y chromosome of the ancestors 300 million years ago. The frightening thing is that the recession continues. 'Men today can be condemned extinct on the evolutionary path of their own race' - Professor Steve Jones - author of the famous book On the origin of men said. Currently, the Y chromosome carries many harmful mutations that have never been seen in our ancestors. Each subsequent generation of men accumulates more genetic errors.

In addition, it is impossible to ignore the social degeneration of men. Women's social progress and changes in social roles cause an unprecedented crisis for the appearance of men and boys. 'In our eyes, the image of the man has changed. We need to reevaluate our thoughts about gender '- psychologist Barney Brwer, who is in charge of the general research project on men of Tufts University in Boston (USA), said. The research results of his group are surprising: the older half of teenage boys feel overwhelmed by girls of the same age, more than half of the boys feel that they are " inferior " than the weak. - they themselves find themselves less productive, poorly organized, more stressed, less energetic, more vulnerable.

Y Y's owners themselves are getting worse on their own - health, education and morality. Clearly all over the world, they are more destitute than women (in Europe is 6: 1 year, in Russia, this ratio is 4: 1).

According to Dr. Dieter Otten, a German sociologist, author of Violence carries the face of men, nowadays in many countries around the world, men are strong but in quantity, they are weak. The number of men is usually less than the number of women. For example, in Russia there are 65.85 million men, while women are 76.35 million (more than 10.5 million men!).

How to save the situation?

Obviously there are too many facilities to worry about. The position of men is weakening not because of cloning, but along with the progress of civilization, the Y's owners are continuing to slide.

Can humans survive without fathers? There are many studies that show that the end of men is not synonymous with the end of man. Medicine is studying many alternatives to replace men in the process of reproduction. Researcher Carol Perterson of Harvard University said: 'The best way is to clone or use semen to replace female cells. Then your semen is not needed. Another way is to cultivate sperm in the animal cell nucleus, experiments on pigs have yielded positive results'. Maybe in the not too distant future, science will naturally bring it back to its original state and the male will disappear. So how do we multiply then? It is possible through cloning. Technically it is a very simple thing: just a piece of a gene from the mother's body is placed in an unborn egg cell, that's it.

For humans, the path to ' simple solutions ' is still far from shaking, but experiments on animals produce more and more positive results. Orrly Lacham Kaplan, a researcher at the Institute of Reproductive and Development Studies in Melbourne (Australia), announced that the first stage of fertilization does not require sperm, because it can create life for one zygote with two mothers. This experiment was successful in mice.

However, not all scientists are optimistic. Many fear that artificial semen will not be able to control itself. According to them, it will be extremely dangerous if the extinction of the strong faction entails the extinction of all humanity. There have been many species of animals extinct because of the meaningless inheritance of males. For humans, a similar situation is likely to occur.

The search for solutions to save the ' seed ' is still being carried out in a positive way. According to Straits Time, Singapore scientists are moving toward stem cell culture. Israeli scientists use acupuncture needles to influence the ' kidney - bladder ' sepsis to increase sperm count.

In the United States, many gentlemen bring sperm to send to ' banks ' to save when they need to use it for a few years when they are sluggish. For wives who have an accident or illness but still want to have a picture of their husband in a child, using sperm reserves is the best source.
