Some research

Research Department Report - Los Angeles, Calif.

A recent 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.
If she is menstruating or menopausal, she tends to be more attracted to a man with scissors lodged in his temple and duct tape over his mouth while he is on fire.
No further studies are expected.
