To bear sons more useful for health

Between a pregnant woman and her unborn child is two-way communication. The fetus is nourished through the placenta, where it receives nutrients and oxygen. However, the latest American study proves, the cells of the unborn baby move in the opposite direction, passing through the mother's body to her brain. In addition, the DNA of the male child may remain in the mother of the boy a few decades after birth.

Scientists discovered in the body of the female gene is present only in the Y chromosome has a strong half of mankind. The group of experts of the Center for cancer research Fred Hutchinson headed by William Chan has documented the presence of cells of a male fetus in the mother's body 63% of examined women. Moreover, scientists were able to conclude that the use of these male cells, which were present not only in the brain but also in the blood, lungs, heart, liver and other organs of women.

This phenomenon is called microchimerism. It is believed that the sons of DNA can increase the immunity of women in the fight against breast cancer. Among the benefits from the influence of "fresh" cells in the mother's body belong to its efficacy in rheumatoid arthritis and the acceleration of the recovery of damaged tissues. Scientists believe that male DNA is able to prevent the development of Alzheimer's disease. However, there is a reverse trend. Microchimerism can cause autoimmune diseases, and it is associated with a high risk of intestinal infections and skin cancer.
