According to a study published, a woman's voice sounds sexier when she is fertile. It has been said earlier that flirtatious behavior and changes to body scents are the clues to a women's fertility. The study published in the Journal of Evolution and Human Behaviour found that a woman sounded more attractive during her menstrual cycle which is also the time when she is most fertile.

 

Nathan Pipitone and Gordon Gallup of the State University of New York at Albany asked women to count from 1 to 10 during their menstrual cycle. Later when the recordings were played at random then it was judged by both men and women that the women's voices were the most attractive during their prime fertility period.

 

According to the researchers the results showed an increase in the attractiveness of women's voices during their menstrual cycle. However the hormonal contraceptives had no effect on the women.
