[Glucose tolerance and plasma testosterone concentrations in men. Results of the Asturias Study].

Background And Objective: Studies in men have demonstrated a correlation between serum concentrations of androgens and sex hormone binding globulin (SHBG) with the presence of impaired glucose tolerance, diabetes and metabolic syndrome. The aim of this study was to evaluate circulating levels of total testosterone, SHBG, and bioavailable testosterone in the cohort of the Asturias Study and their association with the degree of glucose tolerance and metabolic syndrome.

Patients And Methods: The study population consisted of 282 men aged 36 to 85 years old with normal concentrations of total testosterone.
