Aim: To determine the serum testosterone levels in the type 2 diabetes mellitus and its correlation with biochemical parameters of glycemic and lipid metabolism.
Methodology: A cross sectional study was conducted at Department of Biochemistry and Department of Medicine, A cross sectional study was conducted at the Department of Biochemistry, Diabetic outpatient department and Department of Medicine, Liaquat University Hospital. Male type 2 diabetics (n=100) and age matched male (n=100) were included as cases and control for study purpose. Diagnosed cases of type 2 DM, male gender and 40 – 60 years of age were included in the study protocol. Physical examination of male type 2 diabetics was performed by a consultant physician. Sera were separated from blood and stored in refrigerators at – 200C. Blood glucose, A1C, and blood lipids (cholesterol, triglycerides, LDLc and HDLc) were detected by standard laboratory methods. Serum testosterone was measured by ELISA (competitive immuno- assay) assay commercial kit. Data was entered in Statistical software SPSS 21.0 version (IBM, Incorp, USA) for statistical analysis (P≤0.05).
Results: Mean±SD age of male type 2 diabetics was 53.2 ± 11.1 years compared to 54.5±10.4 years in control (P=0.056). Serum Testosterone in cases was 10.85±4.7 mmol/L compared to 13.39±3.8mmol/L in control (P=0.0001). Low testosterone level was noted in 46% male.Serum Testosterone shows inverse correlation with RBG (r= -0.31, P=0.003), A1C (r= -0.23, P=0.014), Cholesterol (r= -0.24, P=0.014), TAGs (r= --0.78, P=0.0001) and HDLc(r= -0.70, P=0.0001). Serum testosterone proved positively correlated with LDLc(r= 0.670, P=0.0001).
Conclusion: The present study finds low serum testosterone in male type 2 diabetes mellitus patients
