Osteoporosis Strong Bones via Tailored Hormones

Interest in alternative preventive strategies against bone loss has intensified in light of the recent announcement of risks associated with hormone replacement therapy. Previous cell culture studies showed that estrogen and androgen protect bone through a mechanism distinct from the DNA-mediated mechanism underlying their effects on reproductive organs. Kousteni et al. now show that a synthetic compound (estren) that mimics these "nongenotropic" effects can increase bone mass in estrogen- or androgen-deficient mice without adverse effects on reproductive organs.
