Beware of that sultry voice: a woman’s voice sounds sexier when she’s at her peak of fertility. When men listened to the voices of women at different points in their menstrual cycles, they rated the sound of women at peak fertility as most attractive. Hormones throughout the menstrual cycle change the quality of a woman’s voice, possibly by altering the pitch. Women are more receptive to sex at the same fertile point in their cycles. If she seems irresistible, make sure you have a condom. Or maybe it’s the perfect time for phone sex.
