Why is it only women who have to worry about osteoporosis as they get older?
One reason may be that male menopause, sometimes called andopause, comes later and is a lot slower than menopause in women.
But it may also be, according to the journal Endocrine-Related Cancer, a matter of estrogen production.
After menopause, women still produce estrogen -- in breast tissue, where it doesn't do much good. But men also produce estrogen -- in bones, where it helps prevent osteoporosis.
