The Contraceptive Song
And you thought testing various secretions of the body and measuring temperature at various times of the month can tell you the “safe” period for that date with hot dude?
Here is an alternative.
A woman raises the pitch of her voice during her most fertile period of the month in an unconscious boost to her femininity, according to a US study. [...]
An analysis of the recordings revealed the closer a woman was to ovulation the more she raised her pitch.
The increase in tone was only slight – it wasn’t Minnie Mouse on helium – but the peaks were enough to be picked up by the voice decoder and presumably by the male ear, as well.
Aha !
