Who made the comment about the body shutting down during a rape before Akin?

This story has blown up in the last few days, it is everywhere. However, I distinctly remember reading an almost identical statement (about pregnancy not happening during a rape because a woman’s body will shut down to protect itself), sometime in the last year from a different politician. That story did not blow up like this one, but I know this is not deja vu.

Does anyone remember this? Do you know who said it before?
