How men are conned by a woman's sexy wiggle of the hips…
The sight of a woman's sashaying hips may be enough to make a man go weak at the knees. But he may well be reading too much into her behavior.
A study has shown that women walk with a wiggle when they are at their least fertile - and adopt a less "sexy" gait when they are more likely to conceive. The apparently contradictory finding - which belies earlier evidence that women's behavior becomes more alluring around the time of ovulation - amounts to an evolutionary con-trick on men, scientists said.
This is because genuine signals of sexual availability, such as subtle changes in smell and facial expressions, can be detected only close up. Men who pick up on these signs are likely to be close friends and acquaintances - and therefore more suitable fathers.
However, signals such as gait can be spotted at a distance by strangers who could be unsuitable mates. Having a less-attractive walk around the time of ovulation therefore allows a woman to disguise her fertile period from undesirable men, it is suggested.

For her research, Dr Provost dressed female volunteers in suits covered with light markers and filmed them as they walked, using a computer to study their gait, New Scientist magazine reports today. Researchers also looked at saliva samples to find out where each woman was in her menstrual cycle.
They discovered that the most fertile women walked with less pronounced hip movements. They also kept their knees closer together as they moved. The least-fertile women, by contrast, had the most swinging gaits and the biggest "wiggles".
Several previous studies have suggested that a woman's behavior changes around the time of ovulation to make her more attractive to men. A recent American study, for instance, found that exotic dancers earn more tips when they are at their most fertile.
Other research has shown that women's body odor is at its "least intense and most attractive" when they are at their most fertile and that women are more likely to wear revealing outfits when sub-consciously looking to conceive.
