The reason men live without life is women

There is a link between the loss of Y chromosome in blood cells and the reduction in life expectancy, especially the risk of high mortality from cancer. This is the reason why men do not live as long as women.

The changes in DNA of normal cells accumulate throughout life. And those changes often lead to diabetes, cancer and other diseases.

An international group of scientists analyzed DNA on blood samples from 1,600 elderly people. The results show that the majority of genetic changes occur because of the loss of the Y chromosome in white blood cells.

In addition, scientists also found a clear link between the Y chromosome and the risk of dying from cancer. Researchers of immunology, genetics and pathology Lars Forsberg at Uppsala University have demonstrated that men who have lost Y chromosomes in many blood cells rarely live long lives, despite their deaths. What causes.
