UCLA study
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.
