There has been some research suggesting that a woman’s movements change when she is more fertile, making her more attractive to men.
Now, a study published in the journal Personality and Individual Differences has found that a woman’s fertility even affects her attractiveness on the dance floor.
Researchers filmed the silhouettes of nearly 50 women between the ages of 19 and 33 dancing to drumbeat from a Robbie Williams song during the fertile phase of their menstrual cycle and again during their non-fertile phase.
The videos of the silhouettes were then shown to 200 male undergraduate and graduate students who rated the women’s attractiveness on a 7-point scale. The men were not informed that fertility was being analyzed.
Interestingly, fertile women received an average score of 2.88 while dancing and 3.31 while walking. The non-fertile women received an average score of 2.72 while dancing and 2.98 while walking.
The researchers concluded that subtle changes in a woman’s movement in response to reproductive hormones may make her more attractive to men.
