The great thing about this reduction in sperm count is that overpopulation will slow!
I doubt it. If it has been cut in half, thats several millions sperm still available. We would need to see an increase in female sterility for populations to decline. Male sterility won't do it, because one man can get many women pregnant. And people still want their own babies and won't adopt.
Yeah or they get fertility treatments and become "octomom" and get their own TV show.
I'm gonna get sterilized as soon as I can. I don't want any freakin' babies. Can you imagine a mini me? Scary thought.
