Couple of other things:

What's wrong with going month-about? Then the guy would only be getting a jab every other month and you'd both get a regular break from the hormone influx. Or maybe, since they take a wee while to settle, quarter-about or something. Seems to me like the best of both worlds.

Secondly, the one really solid argument for the guy taking the contraception is that in the rare event that long-term use did affect fertility (and assuming the same risk level, for the sake of the argument), sperm is (a) a lot cheaper (ie: potentially free) and easier to store than eggs and (b) much, much easier to have a successful pregnancy with after storage. Turkey basters are a lot more straightforward than egg-implantation.
