Context |
In normal bone, bone formation and bone resorption are closely coupled. In osteoporosis, the net rate of bone resorption exceeds the rate of bone formation, resulting in a decrease in bone mass without a defect in bone mineralization. In women, osteoclast activity is increased because of decreased estrogen; as men and women age > 60 yr, osteoblast activity drops off. Men with prematurely decreased testosterone may have increased osteoclast activity.
