First it's NOT a theory!
This is probably going to go WAY over your head as the physiology and reproductive functions are more complicated then you obviously can comprehend but...
I know you won't understand this in polite language so I've used Urban language for you..
The role of the cervical mucus(when a woman is gushing a sticky fluid) is to nourish, protect, and speed the sperm on its way up through the uterus and into the Fallopian tubes so that it can fertilize the egg and help you in getting pregnant.
Female orgasm (when a woman comes...)
that occurs close to the time of ejaculation, or after ejaculation, has also been found to slightly increase conception rates.
So if you have any understanding of conception/cervical mucus and sexual gratification then maybe you can understand what Akin was getting at.
That when violent, physical forced sex occurs there is less chance for sexual enjoyment one would assume!
Put another way, if a woman isn't enjoying it, she doesn't gush as much sticky fluid) and when the rapist comes, because the woman isn't gushing as much there is less chance of the rapist come stickin'! Hence less chance of pregnancy!
So what Akin was saying is IF a legitimate rape occurs, there is not as much sticky stuff exuded by the woman hence less chance of pregnancy!
BUT if the woman in the throes of pleasure comes several times and it's an enjoyable experience, greater chance of getting pregnant.
Then when she finds out that her consensual intercourse results in pregnancy some woman cry "RAPE"...thus illegitimate rape claim!
Check out the scientific explanation if you have the intellectual capacity AND integrity to find out the TRUTH!!!
