If you reverse the polarity, do the sperm go backwards?

Silverwing was referring to this news story.

 

Chris -  I'm not sure if they tested that, but my thought would be probably not because they're turning the sperm from something that’s inactive to something that’s active.  But it’s a good thought!

    It seems like a hot topic in a way I guess. :)  Anyway, I thought I would help out to some degree if I can.  Sperm will not swim the other way as some may think.  What does take place though is if a male thinks his mate is cheating on him with his sperm within the female after intercourse the sperm will take a life of its own and act upon the the 'foreign' sperm and repel the 'new sperm' from getting into the egg area in order to impregnate.  In a way, the sperm is programmed from the original donor who may be thinking his girl is cheating on him.  Simply put i guess.
