Zusammenfassung:To determine whether prostate-specific antigen (PSA) concentrations in type 2 diabetic men with hypogonadotrophic hypogonadism are lower than those in eugonadal men with type 2 diabetes and whether PSA concentrations are related to plasma testosterone concentrations. In this cross-sectional study, we measured serum total testosterone, sex hormone-binding globulin, free testosterone, PSA, hematocrit, and hemoglobin A1c in consecutive type 2 diabetic men who presented to 2 endocrinology referral centers between January 2006 and January 2007. We collected other clinical and demographic data including age, height, weight, and ethnicity. Of 400 eligible patients, 280 men met inclusion criteria. Plasma PSA concentrations were lower in type 2 diabetic men with low free testosterone concentrations than in those with normal free testosterone concentrations (0.89 +/- 0.07 ng/mL vs 1.10 +/- 0.08 ng/mL, [corrected] P = .011). PSA concentrations were positively related to age (r = 0.34, P
