Girls hands are, for the most part, small. This is dictated largely by genetics. Because their hands are small, the bones and ligaments are inherently weaker than that of much larger, male hands. So, when engaging the rigorous button-mashing routines of sparring, their fingers naturally tire much quicker than male fingers. This is not to say that women aren't better than men at sparring. It's just to say, much like the differences between a cheetah and, say, a lion -- both strong predators, but lions can run further than cheetahs -- that men can out-button-mash women. If women could stand the pain (but we all know their weak minds prevent them from doing so), I would imagine that they would be just as good as, if not better than, men.

It's all very elementary.
