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 a man 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.
