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 while he is on fire.

No further studies are expected.
