A recent study at the University of Missouri Medical School

A recent study at the University of Missouri Medical School shows that the type of men's facial features that a woman finds attractive can differ, depending upon where she is in her menstrual cycle.

For example: Most of the month a woman is attracted to men with rugged and masculine features.

If she is ovulating, she is attracted to men with smooth, clean-shaven features.

During her period or if she is menopausal, she is more prone to be attracted to a man with scissors shoved in his temple and a bat jammed up his butt while he is on fire!
