    Should be a LESSON for Spookycolt.

    But it WON'T be, of course.
    So...any comment on the OP??

    The possibility is interesting.

    This is intriguing:


    our findings suggest that Mc of fetal origin could impact maternal health and potentially be of evolutionary significance.
    Almost like discovering stem cells!

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.


    Your link only goes to a home page.
    I agree it is speculative, but is it promising???

    The link was to show WHAT the NHI was.

    You didn't. I just thought it was an odd response.
    OK - I found out what the reference to the "New" study was all about.

    There was a study in 2005


    https://www.ncbi.nlm.nih.gov/m/pubmed/16084184/


    and 2012

    Male Microchimerism in the Human Female Brain

    Poorly written article, should have said 'latest' not 'new'.

    In actuality, however, that*study (which was published in PLOS ONE in 2012, despite being billed as “new” in 2017) demonstrated for the first time the presence of genetically distinct male cells in the brains of women (who had been examined in autopsy). The existence of male cells in the bodies of females, in general, is not news. As discussed in a PLOS ONE blog*post describing that 2012 study, their presence is typically ascribed to cells from a male fetus from a prior pregnancy:

    The idea of two genetically distinct populations of cells, or their DNA, residing in one individual isn’t new. It’s called microchimerism. […] Medical chimerism arises after a transfusion or transplant, and it may follow pregnancy. Our microbiomes, the bacteria within us, are more like guests than body parts.

    [The research groups responsible for the 2012 study] found Y chromosome DNA sequences in several brain regions in autopsy slides from 37 out of 59 women. Such DNA liberated from fetal cells can come from several sources: children, fetuses that never made it to be born, older siblings, or twins. Both son and daughter DNA partake in this “feto-maternal trafficking,” but female DNA, at the chromosomal level, is harder to detect amid the maternal two X’s.


    The most likely source of male [microchimerism, Mc] in female brain is acquisition of fetal Mc from pregnancy with a male fetus. In women without sons, male DNA can also be acquired from an abortion or a miscarriage. The pregnancy history was unknown for all but a few subjects in the current studies, thus male Mc in female brain could not be evaluated according to specific prior pregnancy history. In addition to prior pregnancies, male Mc could be acquired by a female from a recognized or vanished male twin, an older male sibling, or through non-irradiated blood transfusion.

    But, YOURNEWSWIRE thought it meant something different:

    Through the study the researchers assumed that the most likely answer was that all male DNA found living in the female brain came from a male pregnancy. That was the safe, politically correct assumption. But these researchers were living in denial. Because when they autopsied the brains of women who had never even been pregnant, let alone with a male child, they STILL found male DNA cells prevalent in the female brain.
    At this point the scientists didn’t know what the hell was going on. Confused, they did their best to hide the evidence until they could understand and explain it. They buried it in numerous sub studies and articles, but if you sift through them all you will find the damning statement, the one line that gives the game away and explains exactly where these male DNA cells come from.


    Of course YNW offer no sources to back up their claims.
    You are ignoring the study altogether and blaming the source. Is the study wrong? If so, how do YOU know? Did you do your own study?

    Listen, I get that this is an uncomfortable topic, but you guys are completely missing the boat, here. This was not the only study, the only evidence, nor the only one to reach these findings.

    The most likely explanation is that during a pregnancy cells from a male fetus slipped across the placenta, circulated in the mother’s body and lodged in her brain.
    Yes. Yes, that's the most likely explanation. By FAR. And it is NOT saying the woman absorbs male DNA from every male who schtupps her. Only from those who succeed in IMPREGNATING her. Which is NOT what the sensationalistic thread title is claiming, is it??

    Wow, this isn't fake news, people. This has actually been observed in quite large numbers.

    NO -- it has not been debunked by Snopes.
    Um, one reported deduction from this study was that women who orally injest semen are less likely to develop breast cancer.

    That medical finding has yet to be incorporated into our 8th grade sex education classes, however.

    But perhaps it should be. Whaddaya think?

    No wonder Trump loves the uneducated they never bothered to check facts. FACT CHECK: Do Women Retain DNA From Every Man They Have Ever Slept With?

    After Pregnancy, Many Women Have Bits Of Male DNA In Their Brains
    Carrying a male fetus found to cause microchimerism

    Mothers aren't just emotionally connected to their sons. A new study shows how genetic material can be passed on from fetuses during pregnancy, travelinging through the human blood-brain barrier and settling in--and it might be relatively normal, too.

    Researchers took brain autopsies from 59 women between the ages of 32 and 101; a full 63 percent had the genetic material inside (the oldest woman found with an example of it was 94). The condition is known as a type of microchimerism, and it might've stayed with the women from their pregnancy, all the way until they died.

    That's a small sample, so it's tough to draw direct conclusions on the health effects--positive or negative--that are related to it. Thirty-three women in the sample had Alzheimer's; the other 26 were neurological-disease-free. But that doesn't mean we're completely in the dark about microchimerism. From a statement on the study:

    However, other Hutchinson Center studies of male microchimerism in women have found it to impact a woman's risk of developing some types of cancer and autoimmune disease. In some conditions, such as breast cancer, cells of fetal origin are thought to confer protection; in others, such as colon cancer, they have been associated with increased risk. Hutchinson Center studies also have linked lower risk of rheumatoid arthritis to women who previously had given birth at least once as compared to nulliparous women.

    Yes, during pregnancy. Now, compare THAT to the sensationalistic title of this entire thread.

    I think that says a lot.
    I sent you the actual data. Did it kind of sound ridiculous to you? Didn't you even feel and inkling of an urge to check it? You don't have to answer it I know the answer

    NOTHING that either you or the OP have posted, at least thus far, has offered ANY support to the theory that this can happen simply during the sex act. EVERY link you have posted is SPECIFICALLY talking about pregnancy.

    You DO understand, I certainly hope, that a woman does NOT become pregnant every time a man FUCKS her.
