High-pitched voices mark ovulation

Well, here's a novel way of testing whether you're ovulating - check the pitch of your voice... New research has found that a woman's voice gets higher when she is closer to ovulation.

A team at the University of California monitored and recorded women's voices at different times during their menstrual cycle. They found that the pitch rose when a woman was close to ovulation, and was significantly lower during less fertile times of the month.

The research is published in the Royal Society Journal Biology Letters, and you can read more about it on the Royal Society website
