Male microchimerism, the presence of a small number of male cells, in women has been attributed to prior pregnancies. However, male microchimerism has also been reported in women with only daughters, in nulliparous women and prepubertal girls suggesting that other sources of male microchimerism must exist.
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, (this is the important part) 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.
Great job cutting off the very next sentence you fucking faggot!
We speculate that sexual intercourse may be important but other sources of male cells likely exist in young girls.
Blow it out your ass
Btw,
I'm pretty over the whole boarder wall that never got built and hopefully never will be as it would be a monumental waste of resources. I'm on the side of the butterfly sanctuary.
I'm a huge supporter of national parks and land conservation. We have some of the most gorgeous landscape and wildlife in the US. To tear it all up for boarder walls
a boarder is someone you let live with you, and a border is a line separating two jurisdictions. Fucking know it all retard. Or are you just a dirty foreigner pretending to be one of us?
Teehee, I figured that was a typo as I wrote it but never bothered to correct it. I'm so flattered that you're seeing what else I'm up to! Thanks for pointing that out!

So...they speculate. Anything beyond that? Any proof? Or is it just "we think so"? They didn't seem to test for that
