  Estrogen plays an important role in maintaining bone structure and density. When estrogen levels decrease, such as after menopause, the risk of osteoporosis and bone loss rises 8th . Low estrogen levels can lead to porous, weakened bones and osteoporosis 6 .   The majority of postmenopausal females with osteoporosis have bone loss related to estrogen deficiency. The rapid bone loss results from an increase in bone turnover with an imbalance between bone resorption and bone formation 4 . At a cellular level, several mechanisms contribute to the bone loss related to estrogen deficiency. Estrogen affects bone cells, including osteocytes, osteoblasts, and osteoclasts. The lack of estrogen ages the expression of estrogen target genes, increasing the secretion of IL-1, IL-6, and tumor necrosis factor (TNF). Studies have also shown that estrogen deficiency directly affects cell differentiation and apoptosis. The net effects of estrogen deficiency are increased bone turnover and enh...
