Okay well I already knew this.. in fact, many people did. It’s just that something like this is definitely not talked about in our sex-crazed culture. The first sentence of the story says it all:
“Birth-control pills could screw up a woman's ability to sniff out a compatible mate, a new study finds.”
It comes down to BO. The body gives off an odor of possible compatibility. “Major histocompatibility complex (MHC) genes are involved in immune response and other functions, and the best mates are those that have different MHC smells than you. The new study reveals, however, that when women are on the pill they prefer guys with matching MHC odors.”
The pill aside, I think that MHC would naturally affect more women than men. I don’t know many men who date women in large part based on MHC – but women seem to me to be a bit more complicated than men on this issue. And that’s no slam on women. If you remember back to when God created the universe, each thing he made was more complicated then the last. His last creation was surely the most complicated: woman. And this is not simply psychology but also physiology. Women are physiologically more complicated than men.
Which is one reason why the pill is so bad for women.
So what does the pill do that is so bad? “Based on the work by Claus Wedekind, a University of Lausanne researcher who preformed similar studies in the 1990s, Roberts suggests a likely reason for the pill's effect on a woman's odor preferences. The pill puts a woman's body into a hormonally pregnant state (the reason she doesn't ovulate), and during that time there would be no reason to seek out a mate.”
In other words, when women are pregnant their body tells them not to look for mate. So when a woman on the pill (and thus in a hormonally pregnant state) is looking for a man, her body is directing her to find an incompatible man. And people wonder why so many marriages end in divorce – but I think selfishness can have sometimes impact this, too.
And I’m sure contracepting for the sake of enjoying sexual pleasure has nothing to do with selfishness.
