Men need estrogen too (for healthy bones)

Osteoporosis and weak bones are generally thought of as a women's issue, and although women are 4 times more likely to suffer from "brittle bones," with 1 in 12 men getting the disease it's a serious issue for them too.

A common culprit for women who have weak bones is the decline in estrogen after menopause, but what about for men? Surprisingly, most men have higher levels of estrogen than most post-menopausal women, which may be why they generally have lower risk. But those men who have a lower number of active estrogen metabolites also have a correspondingly higher risk of developing lower bone density (low -- high -- low -- did that make sense?).

But don't worry guys, there are no plans yet to start generally prescribing estrogen hormone replacement for men. Not yet anyway...
