A woman's voice becomes more attractive when she is most fertile. That's according to Nathan Pipitone and Gordon Gallup of the State University of New York at Albany.

'Sexy' voice gives fertile women away = 'Sexy' voice reveals fertile women's secret that they are "in heat"?
(I wonder whether I have used "in heat" properly here. Can the "in heat" be used when it refers to human oestrus? No offense anyway.)
"In heat" isn't normally used re humans, it's offensive.
'Sexy' voice indicate when women are (at their most) fertile.
Thank you MH.
