A study conducted by UCLA's Department of Psychiatry has revealed that the sorts of features 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 a spear lodged in his chest and tape over his mouth who is on fire.

No further studies are expected.
