UCLA researchers publish landmark meta-analysis of sexual preferences at ovulation

If she loves you and then she loves you not, don’t blame the petals of that daisy. Blame evolution.

UCLA researchers analyzed dozens of published and unpublished studies on how women’s preferences for mates change throughout the menstrual cycle. Their findings suggest that ovulating women have evolved to prefer mates who display sexy traits – such as a masculine body type and facial features, dominant behavior and certain scents – but not traits typically desired in long-term mates.

*Evidence of evolutionary protection against inbreeding in women?*

Through an innovative use of cell phone records, researchers at UCLA, the University of Miami and Cal State, Fullerton, have found that women appear to avoid contact with their fathers during ovulation.

“Women call their dads less frequently on these high-fertility days and they hang up with them sooner if their dads initiate a call,” said Martie Haselton, a UCLA associate professor of communication in whose lab the research was conducted. (more…)
