LOL roasties, this is why older cultures knew a women was tainted once she had sex, the more partners the crazier she'll get
Giving a whole new meaning to "pregnancy brain," a new study shows that male DNA—likely left over from pregnancy with a male fetus—can persist in a woman's brain throughout her life. Although the biological impact of this foreign DNA is unclear, the study also found that women with more male DNA in their brains were less likely to have suffered from Alzheimer's disease—hinting that the male DNA could help protect the mothers from the disease, the researchers say.

The implications of the study are that any mates a female has had may leave some legacy—in the form of physical or other traits that are carried in the semen (but not the DNA-containing sperm)—that could show up in her future offspring with another mate.
