Osteoporosis and osteoporosis-related fractures are usually considered conditions of postmenopausal or elderly women, but nearly 30% of hip fractures occur in men.1 Both men and women experience age-related losses in BMD, which has been linked to an increase in fractures and disability. However, the changes that occur to bone with aging are different between the sexes. Although both men and women experience declines in femoral neck BMD and cross-sectional area, women experience a loss of bone rigidity, while men seem to compensate with a small but significant increase in girth of the femoral neck.2 As a result, men tend to present with osteoporotic fractures about 10 years later than women.3 However, once hip fractures occur, mortality is higher among men than among wome
