A study at the University of Manitoba shows that the type of facial features that a woman finds attractive can differ, depending upon where she is at in her menstrual cycle.

For example: If a woman is ovulating, she is attracted to men with rugged and masculine features. If she is menstruating or menopausal, she is more prone to be attracted to a man with scissors jammed in his temple and a bat shoved up his ass while he is on fire.
