Effect of testosterone therapy on bone formation in an osteoporotic hypogonadal male

Abstract

Osteoporosis has been reported to complicate androgen deficiency in males. Accordingly, we have evaluated an osteoporotic hypogonadal male with bone histomorphometry before and after 6 months of testosterone replacement. Androgen therapy resulted in increases in relative osteoid volum, total osteoid surface, linear extent of bone formation, and bone mineralization. The dramatic histological response to hormonal replacement confirms the importance of androgens in bone modeling and remodeling.
