BBC NEWS Health Fertile women 'have sexier voice': "A woman's voice becomes more alluring when she is at her most fertile, according to US research.
Recordings of women taken at different points in their menstrual cycle were played to people of both sexes.
New Scientist magazine reports that the voices rated as most attractive belonged to women at peak fertility.
The study suggests sex hormones can alter the workings of the voice box, but the change may be too subtle to pick up in many situations.
Human reproduction differs from reproduction in other mammals in that there are no obvious signs that a woman is at her fertile phase.
However, scientists have suggested that very subtle changes caused by the rise and fall of different sex hormones can be detected by men, who then perhaps find a woman more attractive without necessarily even realising why."
