title: Low serum testosterone concentrations in hospitalized men with poorly controlled type 2 diabetes.
abstract: Our aim was to examine whether serum testosterone concentrations are in fact low in hospitalized men with poorly controlled type 2 diabetes compared with healthy men. In this study, 79 men aged 40 years or older (41 healthy men and 38 men with type 2 diabetes) were included. Total testosterone and sex hormone-binding globulin levels were measured. The average duration of diagnosed diabetes was 10.8 years and the mean glycated hemoglobin value was 10.8%. Total testosterone concentrations were lower in men with type 2 diabetes than in healthy men, after adjusting for age and body mass index (3.83±0.32 ng/mL vs. 5.63±0.31 ng/mL, P<0.001). In conclusion, this study shows that serum testosterone concentrations are lower in hospitalized men with poorly controlled type 2 diabetes than in healthy men. Therefore, men with poorly controlled type 2 diabetes should undergo further assessment for hypogonadism.
