Though osteoporosis primarily affects women, men are also at risk of developing osteoporosis. In the USA alone more than 20% of the total osteoporotic patients are men. Men who develop osteoporosis are above the age of 50. They develop painful manifestations of the condition mostly around the hips. And the diagnosis also happens only after an unexpected fracture. The causes for osteoporosis among men are genetic predisposition, age, organ transplants, long term drug interactions and hormonal imbalances.
