*big grin*..well, tweaked or not, it doesn't hurt to make the point. Are you SURE they sterilize males in wildlife control? If the Alpha wolf does manage to defend his harem, fine...but the other males are often sneaky critturs!...Humans are, if I may say so, even sneakier!

Yep...vasectomies are a fine tool in some cases...(especially in a captive, controlled population), but if you DO try to do vasectomies on a large % of men, you'd still have to do something about the women too!,,,just extra work & expense.
