In addition to the counterarguments already mentioned, here is another: a kick to the groin, even well placed, is not always guaranteed to bring a man down. If you are really in a life or death fight it is possible for a man with that much adrenaline in his system to keep going. It is painful but it doesn't actually disable his fighting ability in any way if he can push through the pain. I think that generally most guys don't hate each other enough to inflict that kind of pain unless it is a life or death situation. And if you are in a life or death situation there are better options to incapacitate the opponent.
