A new study from the University of Seattle and the Fred Hutchinson Cancer Research Center just made a blockbuster discovery when it comes to female genetics. Researchers found that women retain and carry living DNA from every man with whom they have sexual intercourse, according to the new study by the University and cancer center.
The study, which was focused on the female brain and genetics, found that 63% of women have brains that harbor DNA that originated from another individual, and are genetically distinct from the cells that make up the rest of the woman.
After a careful study, the researchers found that the male DNA in those women’s brains were from present (or former) lovers. The DNA was genetically fused to the women’s brain and will be there for her entire life.
A total of 154 girls were studied of which 21 (13.6%) tested positive for male microchimerism. There was a tendency that girls were more likely to test positive for male microchimerism if their mothers previously had received transfusion, had given birth to a son or had had a spontaneous abortion. Furthermore, the oldest girls were more likely to test positive for male microchimerism.
However, less than half of microchimerism positivity was attributable to these factors. In conclusion, data suggest that male microchimerism in young girls may originate from an older brother either full born or from a discontinued pregnancy or from transfusion during pregnancy. We speculate that sexual intercourse may be important but other sources of male cells likely exist in young girls.
Far from demonstrating that 100 percent of a woman’s male sexual partners have male cells that de facto become part of their body, the studies cobbled together by YourNewsWire show that even if sexual intercourse transferred cells from a male that later became incorporated into the female partner’s body (which science has only speculated about at this point), it clearly wouldn’t happen in all cases.
We are also unsure, for the record, what motivation would exist for scientists to hide the truth about male microchimerism in the first place.
