A sexy swing of the hips may attract admiring glances, but it is not a covert sign a woman is ready to breed, according to researchers.
A Queen's University, Ontario, team examined volunteers' walks and the levels of sex hormones in their saliva.
They found those with alluring walks were the furthest away from ovulation.
A British expert said the research, featured by New Scientist magazine, supported the idea women disguise their fertility to deter unsuitable partners.
Tango’s Take Hmm. Here’s our shot at explaining this. Men are naturally most attracted to a woman when she is most fertile (facial clues, hormones, scent, etc.) so when she is not fertile there is a slight lack of ‘sex appeal.’ She, therefore and unconsciously, needs to add a little wobble-wobble/shake-it-shake-it to her walk. That makes some sense, right? No? OK, the theory put forth in study is that women who are most fertile actually try to hide it from long-distance observers by acting a little frumpier. Does that make sense? All we know is that we think we get tricked into thinking women are hot pretty frequently and we can’t really blame it on fertility. More like bad lighting, high expectations, and beer goggles.
