Collectively with data showing the presence of male DNA in the cerebrospinal fluid , our results indicate that fetal DNA and likely cells can cross the human blood-brain barrier (BBB) and reside in the brain. Changes in BBB permeability occur during pregnancy  and may therefore provide a unique opportunity for the establishment of Mc in the brain. Also unique to our study are the findings that male Mc in the human female brain is relatively frequent (positive in 63 of subjects) and distributed in multiple brain regions, and is potentially persistent across the human lifespan (the oldest female in whom male DNA was detected in the brain was 94 years)."
In de studie keken ze vooral naar DNA die achter is gebleven door eerdere zwangerschap.
Echter bij autopsie van overleden vrouwen die nooit zwanger zijn geweest is ook DNA gevonden van mannen waarmee de vrouwen vroeger seks hebben gehad.
"CONCLUSIONS: Male microchimerism was not infrequent in women without sons. Besides known pregnancies, other possible sources of male microchimerism include unrecognized spontaneous abortion, vanished male twin, an older brother transferred by the maternal circulation, or SEXUAL INTERCOURSE. Male microchimerism was significantly more frequent and levels were higher in women with induced abortion than in women with other pregnancy histories. Further studies are needed to determine specific origins of male microchimerism in women.
Ziek, blijkbaar blijft DNA van vorige mannelijke partners -permanent- achter bij de vrouw die actief wordt bij een eventuele zwangerschap door een volgende man.
Het kind is bij een sletje dus nooit echt 100% van jou maar ook van Jamal en Tyrone die je meisje tijdens haar uni jaren leerde kennen
Voor de genteresseerden:
Evolutionair gezien is het voor de vrouw natuurlijk voordelig:
"It's important to note what did not correlate with female orgasm during sex. Degree of women's romantic attachment did not increase the frequency of orgasm! Nor did the sexual experience of either partner. Conventional wisdom holds that birth control and protection from disease up orgasm rates, since they allow women to feel more relaxed during intercourse. But no relationship emerged between female orgasm and the use of contraception.
Nor can the study results be explained by the possibility that the symmetrical males were dating especially uninhibited and orgasmic women. Their partners did not have more orgasms during foreplay or in other sexual activities. Male symmetry correlated with a high frequency of female orgasm only during copulation.
The findings support evolutionary psychologists' "good genes" hypothesis: Women have orgasm more often with their most symmetrical lovers, increasing the likelihood of conceiving these men's children..."
"Baker and Bellis found that when women do engage in infidelity, they retain less sperm from their main partners (their husbands, in many cases), and more often experience copulatory orgasms during their trysts, retaining semen from their secret lovers. Taken together, these findings suggest that female orgasm is less about bonding with nice guys than about careful, subconscious evaluation of their lovers' genetic endowment."
TL;DR: Fuck sletjes, vind een schone maagd
