Non-Familial Males ... and Miscarriages

During the time when the commies had Forced The Shutting Down Of The World's Economy, I saw a mainstream news article stating that gynecologists/pediatricians were reporting a noticeable decrease in miscarriages.

This immediately brought to mind the scientific observation that when pregnant mice are exposed to "strange" males, their incidences of spontaneous abortion increases.

And, this lead me to wonder whether the *reason* that almost all ancient civilizations segregated their wives from most contact with non-familial males was precisely because there is a similar, albeit weaker, physiological effect in humans as in mice to cause spontaneous abortions upon contact with "strange" males.

This question will never be studied. of course -- feminism will not allow the question to be asked, nor an honest answer to be given.
