A study worth sharing with friends both male and female:

A study conducted by UCLA's Department of Psychiatry has revealed that
the kind of face a woman finds attractive on a man can differ depending
on where she is in her menstrual cycle. For example: if she is
ovulating, she is attracted to men with rugged and masculine features.
However, if she is menstruating or menopausal, she tends to be more
attracted to a man with duct tape over his mouth and a spear lodged in
his chest with a bat up his ass while he is on fire.

No further studies are expected on this subject.
