Although males are less likely to develop osteoporosis than females, they can develop osteoporosis with advancing age or the presence of certain risk factors.
Paramaters:
(1) age of the patient
(2) T-score (bone density compared to that of a young male)
(3) Z-score
(4) risk factors for fracture
(5) secondary cause for low bone mineral density (BMD)

where:
• Some authors use only the Z score when evaluating a male < 50 years of age, while others recommend using both the Z and T scores.
A patient who does not meet the criteria for osteoporosis but with a T score < -1 SD has osteopenia.
