A new study has found that women carry living DNA from all the men she has ever had a sexual relationship with.

That's right ladies; the startling discovery was made by researchers at the University of Seattle and the Fred Hutchinson Cancer Research Centre. The discovery was made by accident when the team was initially attempting to find out if pregnant women with a son are more susceptible to neurological diseases that men are more vulnerable to.

 

The study began to take a turn when scientists dived deep into the female brain. They discovered the woman’s brain possessed male DNA known as “male microchimerism”. These cells are different to that of the cells that make up a woman.

"63% of the females (37 of 59) tested harbored male microchimerism” and in many part of the brain, the according to the study.

Now, do not be confused by your father's DNA. Your DNA is unique because his and your mother's combine to make you.

At first, researchers thought that the male DNA found in the female brain came from carrying a male while pregnant. But, that was not true. Why? On closer inspection, male DNA cells were still prevalent in the brains of women who had never even been pregnant.

Scientists say there are only four ways male DNA cells are likely show up in the female brain:

* Unknown abortion
* Possibly a vanished male twin
* Older brother transferred by the maternal circulation
* Sexual intercourse

Finding a man's DNA in a woman's brain from the first three sources applies to only  small percentage of women. The only likely option researchers could account for in the study of 63% women who had it was through sexual intercourse.

The implications for women are great. When sperm enters a woman it swims until it hits a wall and them seeps into your flesh. If it is in your mouth, it can get into your nasal areas, behind your eyes and even your inner ear. It then enters your blood stream and collects in your brain and spine. You can never get rid of it.

With every man a woman has a sexual relationship with; she absorbs his spermatazoa which becomes a part of you forever. The study autopsied the brain of elderly women, many of whom have been carrying male DNA for more that 50 years. This starling and fascinating discovery is only the beginning in understanding the true consequences of sexual intercourse.
