[Estrogen and bone metabolism].

The increased rate of bone remodeling that follows loss of estrogen can be accounted for by increased osteoclastogenesis (formation of bone-resorbing cells) and osteoblastogenesis (formation of bone-forming cells). And, estrogen replacement provides an effective prevention of postmenopausal osteoporosis. Genomic and non-genomic actions of estrogen regulate bone remodeling.
