Birth Control Pills Might Alter Mate Selection: Study

WEDNESDAY, Oct. 7 (HealthDay News) -- Could birth control pills be taking human evolution in a whole new, and possibly detrimental, direction?

A review of past research finds that, by altering hormonal cycles, the pill might affect choice of mates among members of both genders in a way that could hinder successful reproduction in the future.

"The use of the pill by women, by changing her mate preferences, might induce women to mate with otherwise less-preferred partners, which might have important consequences for mate choice and reproductive outcomes," said Alexandra Alvergne, lead author of a study appearing in the October issue of Trends in Ecology & Evolution.

"One prediction is that offspring of pill users are more homozygous than expected, possibly related to impaired immune function and decreased perceived health and attractiveness," according to the report by Alvergne, a postdoctoral research associate in the department of animal and plant sciences at the University of Sheffield in England, and colleague Virpi Lummaa.

But another expert thinks this new revelation on the pill, which did indeed revolutionize sex in the 1960s, may have been over-interpreted.

"The study was about female preferences in their relation to hormones in the cycle but that's not the same as your mate selection for a long-term relationship," said Dr. William Hurd, a reproductive endocrinologist at University Hospitals Case Medical Center in Cleveland. "If you don't take into account society maybe we're all animals, but in social situations I don't think there are many women who change who they would mate with at different times of the month. It might change desires or perceptions but, gee whiz, that's a long stretch to changing who you would date, or even who you would go to dinner with."

Women who are ovulating tend to be attracted to so-called "manly men," those with more masculine facial features and traits of dominance and competitiveness, according to background information in the study. They also tend to prefer the man who is not like them, genetically speaking.

And men, given a choice, will gravitate towards an ovulating female rather than a non-ovulating female.

But women on the pill are more consistently in a state that mimics pregnancy, the authors stated.

I guess breast implants would have a similar effect on men.

So, Adam ... what did you decide Can you envision a day when such a scenario would hold up in a divorce court ~ a lady ceases her intake of artificial hormones, wakes up and realizes that she's not paired with Prince Charming after all?

And for us ladies, as we move beyond toting little ones round and about ~ do we finally begin to attract the sweet, sensitive type of fellow

Btw: you men may not need breast implants to achieve similar effects ... if you are milk-drinkers (plenty of hormones there ).

There's a lot of "scientific" research showing biological factors partly explain why (most) women prefer different sorts of men (for different purposes) and/or at different times, including during monthly cycles and life cycles.

I think there has been relatively less research on men showing the biological reasons why males exhibit seeming similar preference switches, preferring mothers for some purposes and/or times and sexpots for others. Probably less formal research on biological causes for males because the other non-biological reasons for it seem so obvious.
