I can't answer those questions but this wasn't some junk scientific study, it was done at a very well known cancer research center and in the conclusion of the study they did include 'sexual intercourse' as a *possible* source for the male DNA.
Of course the internet jumps on this and we end up with sensational stories that women carry the DNA of every loser they ever slept with.
My guess is that the only male DNA a woman might retain from a sex partner is coming from spontaneous abortions of pregancies they were never aware of. A sperm fertilizing an egg is obviously a very different process than blood transfusions, dog bites and organ transplants, and neither you or I have the knowledge to know that difference.
Male microchimerism in women without so... - PubMed Mobile - NCBI
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.
