UNIVERSITY  STUDY (very interesting and short)

A study conducted by Sydney University ‘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 with a cricket bat up his a*se while he is on fire.

No further studies are expected on this subject
