"Sperm Busting Male Pill"

My favorite headline to describe the male pill that's in the works comes from Australia. Reminds me of the "bunker busting" bombs. Very manly sounding--"sperm busting." So far, no long term side-effects.

This is very good news. Men have a less sensitive system than women--it just doesn't change as much throughout the cycle. I'm wonder though, what if a "half-busted" sperm makes it out of the gates and into the egg? Is it possible? Will it make a mutant?

Those would be my questions, anyway.
