Fertile women raise their voice pitch
|
Women’s voices rise and fall in tune with their fertility, according to research by psychologists. |
Recordings of women taken at different times in their monthly cycle show that the female voice rises perceptibly a day or two before ovulation, when women are most likely to become pregnant. |
The findings are the first to point to a link between voice and fertility and build on recent studies which support the idea that humans may be similar to other animals in displaying outward signs of fertility. |
Two years ago, Haselton published another study into female fertility and the monthly cycle, which suggested that women “dressed to impress” when at their most fertile, favouring skirts over trousers and showing more skin. |
The work goes against the long-held belief that humans, unlike many other
animals, hide any evidence of ovulation. |
claimed that women sway their hips more when they are at their most fertile. |
