I really don't understand how you got to forcing everybody to undergo a surgery like this because of discomfort and mood swings once a month. (and I am not dissing Periods I have a number of friends who have make it very clear how unpleasant they are) the reason that girls take contraceptives and seem to have more responsibility in that area is because
1. they have a reproductive cycle that can be started and stopped without harming them. Some Hormonal treatments slow or stop the menstral cycle however when you stop taking the medicine the menstral cycle goes right back to doing its thing. If you tried to stop a guys balls from producing sperm then his balls would permanently stop producing sperm shrivel up and lose there functionality. also they would no longer be able to produce testosterone which would be a bit of a problem.
2) Girls have a greater responsibility to be aware of the risks then men simply because many guys won't be thinking intelligently in the long term.

yes but lets be hones most authors don't have the graphic design ability of a fly and don't often give cover design the attention that it deserves.
