The lascivious swing of a woman’s hips may fascinate men, but watch out: those are not the kind of women who go out to ‘devour’ men!

A new research at Queen’s University, Ontario, and published in the journal Archives of Sexual Behavior checked the connection between female subjects’ walks and the stage of the menstrual cycle based on levels of sex hormones measured in their saliva. Surprisingly, the sexiest walks did not correspond to ovulation, but, on the contrary – to the furthest away days from ovulation.

A British expert said the research, featured by New Scientist magazine, supported the idea according to which women disguise their fertility to deter unsuitable partners. Women have a wide array of subtle methods for suggesting a man that they are in the fertile period, and the hip-swing was expected to be one of them. That’s why the team made videos of the gait of female subjects which were presented to 40 male subjects, put to assess the level of attractiveness based on this, after which the results were compared with the hormonal checks. “The results were so surprising that I repeated the experiment again with another group of male viewers”, said lead researcher Meghan Provost.
