To study the role of clinical, demographic and laboratory factors on the levels of sex steroids, we studied 28 men with type 2 diabetes (DM2) and 27 non-diabetic controls. Body mass index (BMI), waist size and waist-hip ratio (WHR) were measured in all, as well as, glucose, hemoglobin A1c, insulin, peptide C, estradiol, testosterone, and SHBG. The free testosterone index (FTI) was calculated by dividing total testosterone (TT) by SHBG. The HOMA-R index was used as a measure of insulin […]
