"The Pill Makes Women Pick Bad Mates", By Jeanna Bryner, Senior Writer, LiveScience.com, 12 August 2008
Not only is this study's publication brand new this week, its findings apparently have already been observed and published after being "fully peer-reviewed to the highest standards," quietly and without any media coverage I'm aware of, 11 years ago.
Read the actual abstracts and full texts for yourselves. These are clearly not biased, "pro-life" sources.
"The Pill Makes Women Pick Bad Mates", By Jeanna Bryner, Senior Writer, LiveScience.com, 12 August 2008
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.Here's the link for the current study on the Proceedings B of The Royal Society: Biological Sciences journal.
...
Past studies have suggested couples with dissimilar MHC genes are more satisfied and more likely to be faithful to a mate. And the opposite is also true with matchng-MHC couples showing less satisfaction and more wandering eyes."Not only could MHC-similarity in couples lead to fertility problems," said lead researcher Stewart Craig Roberts, an evolutionary psychologist at the University of Newcastle in England, "but it could ultimately lead to the breakdown of relationships when women stop using the contraceptive pill, as odor perception plays a significant role in maintaining attraction to partners."
It's interesting that this finding first was published 11 years ago, without any fanfare. Here is that older study (1997), which also found that "the MHC or linked genes influence human mate choice." The earlier study's abstract is also from Proceedings B of The Royal Society: Biological Sciences:
Their [121 men's and women's] scorings of pleasantness correlated negatively with the degree of MHC similarity between smeller and T-shirt-wearer in men and women not using the contraceptive pill (but not in Pill-users).Meaning, the Pill users were attracted to those with more-similar MHC smells. (Remember, "the best mates are those that have different MHC smells than you.")
I'll leave the details of my own personal history out of this, but as I was on the Pill for well over 10 years to try to stem the advance of my endometriosis, suffice to say that isn't this a "well, well, well!" This explains a LOT!

THis is the funniest most rediculous thig I have ever heard. This should be on Saturday Night LIve.
So, John, you think the scientists comprising England's "national academy of science" are funny and "rediculous" [sic]? You didn't even bother to read the study, did you? We don't make this stuff up. We don't have to. And a scientific journal put out by such scientific academies doesn't have their scientific peers review articles, then publish them after they pass scientific muster, if it's really just so "funny" and "rediculous."
