UCLA study

A study conducted by UCLA's Department of Psychiatry has revealed that
the kind of male face a woman finds attractive can differ depending on
where she is in her menstrual cycle.

For instance, if she is ovulating she is attracted to men with rugged
and masculine features. However, if she is menstruating or menopausal,
she is more prone to be attracted to a man with scissors lodged in his
temple and a bat jammed up his *** while he is on fire.

Further studies are expected.
