Feeling pretty? Hormones may lead women to more partners

Women with high levels of estrogen not only look and feel prettier - but they may act on those feelings by moving from man to man, US researchers reported on Tuesday.

Estrogen, the so-called female hormone, affects fertility and has been shown to make women dress more provocatively and show more thrill-seeking behavior.

Dr Kristina Durante of The University of Texas at Austin and colleagues found that young women felt more attractive when they had high levels of an estrogen known as estradiol, and they acted on those feelings.
