You skipped biology, perhaps, R69. Even with normal sex, there are only 2 days out of a month that a woman is fertile and sperm are viable only about 48 hours. Just that gives only an 11% chance of pregnancy with a single encounter of sex. Couples trying to get pregnant know that just the presence of sperm and egg don't necessarily mean pregnancy. There are other factors that make the rate about 25-50 percent of the time.
From a single sex act, not taking anything else but normal odds into account, the chances of a pregnancy are down now to 3-5%.
Couple fertility specialists speak at great length on proper positions, behavior after coitus, mood, distress of the cervix, etc., etc.
A study I read yesterday said the odds were actually only 2-4% with a rape, and they did not distinguish between types of rape. (For instance, a 16 year old girl and her 19 year old boyfriend constitute a statutory rape in many places, but go into the stats only as "rape".)
That hardly supports the “Fable of the Magic Uterus” theory of Todd Akin.
You just supported the fact that a woman is just as likely to be impregnated by rape as any other sexual encounter. That is not what Akin said. He said women have a magic uterus that will not allow her to become pregnant when raped.
Exactly! Put that with the one who 'claimed' to be raped [but actually weren't] the number gets even smaller.

DISCLAIMER:
The above doesn't mean that I think all women who claimed to be raped are lying, it's just that there is a segment of the population who will lie at the drop of a hat to prevent from putting their own ignorant actions in an unfavorable light.
