It seems there really is something in the way she moves.
Research shows that men are able to spot a woman when she is at her most fertile – simply by watching the way she walks.
Her dance moves are also a giveaway, but the way she walks provides the biggest clue.
Just what signal she gives out remains unclear – but it may involve a wiggle of the hips, say the German scientists.
More than 40 years after the George Harrison wrote the Beatles song Something, the University of Gottingen researchers set out to discover if there really is something special in the way a woman moves.
Forty eight young women were filmed as they walked up and down in a straight line and danced for 30 second bursts.
Their movements were then turned into silhouettes, so that their appearance would not detract from their moves.
The process was done twice – once when the women were at their most fertile and again when the odds of them becoming pregnant were very low.
Two hundred men were then asked to watch the videos of the walking or dancing silhouettes and say how attractive the moves were.
