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.
