Todd Akin (R-MO) says that doctors told him that women can’t get pregnant from rape. The doctor in question was presumably Onesipherous W. Bartley, whose 1815 A Treaties on Forensic Medicine or Medical Jurisprudence explained that conception:

must depend on the exciting passion that predominates; to this effect the oestrum/veneris must be excited to such a degree as to produce that mutual orgasm which is essentially necessary to impregnation; if any desponding or depressing passion presides, this will not be accomplished. (via)

At least we know how up to date a certain kind of Republican is on the medical literature. Aaron ‘zunguzungu’ Bady offers a less generous, but surely more astute, diagnosis:

The thing about a chucklehead like Rep. Akins is that he doesn’t actually care whether or not women have a magical anti-rape secretion in their body that makes conception less likely. That’s the whole point: his right not to have to worry about it. If you look at his entire statement, for example, you’ll notice that his foray into weird science was tangential to his main point, which was, simply, punish the criminal not the child. And this is more or less orthodox GOP doctrine, which has the hammer of law enforcement and looks for nails: solve the problem of rape by hammering the criminal, and make abortion into a crime, so you can hammer that too. But this simple-minded approach stumbles when it runs into the problem of the rape-victim: how to have empathy for the victim (because “victim’s rights” is a central pillar of the law and order approach) while also criminalizing her if she gets an abortion? How to insulate her choice to get an abortion from the contingency she did not control, and could not have chosen?

As many have pointed out, then, the first imperative is to make it her choice, and therefore her fault. But there’s still he cognitive dissonance of a rape victim forced to have the child of a rapist, something that doesn’t sit at all easily in the mind of a right wing family-and-police; she’s still a problem, and a thorny one. And so, a simple answer, for a simple mind: she does not exist. He argues that the rape victim who is impregnated is a fantasy of people who want to make the whole thing complicated and difficult, with their “ethics” and “problems,” and so he invents a “doctors told me” story to make it make sense, to explain how what seems complicated is actually simple. But the fact that he’s just making shit up, that women’s body’s aren’t Nature’s Own Anti-Rape Kit, is irrelevant; when you believe in the super-sufficiency of simple laws (and in The Law), problem-cases just become nails to be hammered down or ignored, while “facts” are nothing more that the warrant for doing so.
