- It makes sense for women to conceal their fertility status but to still send off cues that attract men at that time.
- Human sexuality remains a complex mystery.
Unlike baboons and cats, human females don't advertise their fertility with obvious signals like swollen red bottoms and loud howling.
For years, though, evidence has been building that women become subtly different when they're ovulating. By talking, dressing, acting and even smelling more alluring, studies have suggested, women might increase their chances of having sex when they are most likely to conceive. And even if men don't realize what's happening, they seem to find women more attractive at that time of the month.
A new study offers another view. Focusing purely on the way women talk over the course of a month, researchers found that the female voice is not a reliable predictor of ovulation.
Those results support the theory that, in our species, women tend to conceal the timing of their fertility so that men will be more likely to stick with them for the long haul. And while the conversation is far from over, the findings only add to the complexity and mystery of human sexual attraction.
