DESIGN Population-based retrospective cohort study. SETTING Winnipeg, Man. PARTICIPANTS A total of 902 men who filled at least 2 prescriptions for androgen therapy. MAIN OUTCOME MEASURES Whether men had had baseline prostate-specific antigen (PSA) and testosterone testing before initiation of therapy and whether men had beenmonitored during the first year of treatment. RESULTS Of the 902 men who filled first-time prescriptions during the study period, only 475 (52.7%) had ever had PSA or testosterone tests. Before starting therapy, 315 men (34.9%) had had PSA tests, and 152 men (16.9%) had had testosterone tests. Less than 1% of the entire sample had had 3 or more tests during the year following initiation of therapy. CONCLUSION Indications for androgen therapy in this population appear to be based on clinical symptoms rather than on demonstrated biochemical androgen deficiency. Recommendations for clinical monitoring of men taking androgen therapy are not followed consistently.
