Total cop out: Jezebel says it better than I would at the mo.

But yeah, they're doing tests on Chinese men and have found monthly testosterone injections (and some other stuff) to be 99% effective as male birth control.  For all but 2 of the men the effects were reversible.

So, progress!  Go, science!  Gotta wonder what kind of physical and behavioural side effects extra testosterone is having on those guys, though.  Not that women don't deal with (sometimes major) side effects with hormonal birth control, but I would expect extra testosterone to make people more aggressive.

As always, I'm curious to see where this goes.
