Ensure that they have a better immune system and fewer developmental disorders

Author of "The Stronger Sex": Women are genetically superior to men

Men should be courageous when reading the book "The Stronger Sex", recently published in Germany, because they are not concerned with the title of this book. The author, Sharon Mwalim, a neurogenetics scientist, explains that women have a stronger immune system, fewer developmental disorders, and the fight against Cancer is more successful. “Women are simply stronger than men at every stage of life,” and he says they are genetically superior to men.

Although Mawalim wrote his book before the outbreak of the Corona crisis, what happened in the pandemic is proportional to the picture he painted in the book, because the incidence and death of “Covid-19” disease among men is more than among women.

But the exact reasons for this are still debated.

However, the author believes, in general, that the female component has an advantage in survival ... and this is what explores its causes in the "stronger sex".

Mwalim explained that “this feature is evident through the increase in the life expectancy of women compared to men, as every 100 newborn females correspond to an average of 105 newborn males, and despite this, the number of women is twice the number of men in the age group that exceeds 85 years, and readers may have argued that men are more likely to go to war or smoke more or that they exercise more dangerous jobs, but the author does not see that these arguments are correct.

“We know at the present time that the increase in the life expectancy of women can be attributed to biological factors,” Mwalim wrote, pointing out that a study involving data from more than 11,000 Catholic nuns and monks from Bavaria showed an advantage for women in survival, despite the fact that The monks lived under extensive protection from dangers.

But how is that?

Mwalim answers that the sex chromosomes play a decisive role in this matter. A woman’s sex chromosomes contain two similar pairs of x chromosomes, while a man’s sex chromosomes contain two different pairs of chromosomes x and y, and the latter is responsible for determining the gender of the newborn into a male, and he is also responsible For sperm production, it contains only 70 genes, while the x chromosome contains about 1000 genes.

Mwalim added, "This is how women have more solutions in their genetic set of tools," because they have an X chromosome from the father and one from the mother, and each has different genetic variants.

These additional tools help, for example, in defense against viruses: immune cells are constantly trying to develop better antibodies through mutations, and this leads to women having more different immune genes that compete with each other, which speeds up the antibody development process. .

As a doctor in a Thai orphanage in children with HIV infection, Mawalim noted these results: “Every time a new microbe enters the orphanage, the experienced workers warn all other workers to provide intense attention to the boys.” They are more susceptible to infection than girls.

He added, "His wife recovered faster than he did after a car accident that occurred to them, despite the seriousness of her injuries."

The best-selling author of the book tells of female survival historians and women who have played extreme sports.

The world of honey bees

The author of the book also touched upon the world of honey bees, noting that female worker bees possess double the chromosomes of males, and it is no wonder that females prepare food and produce honey and take care of the hive and defend it, while males are only suitable for one thing which is reproduction.

Mwalim wrote that "males are expelled shortly before the onset of winter, and they do not survive for long," considering that the men's fortune is that they have escaped such a fate.
