Introduction: Diabetes Mellitus(DM) has been linked with low serum Testosterone(T) levels. Low testosterone levels in men with type 2 diabetes have been suggested to increase insulin resistance.

Objectives: We aimed to investigate if blood sugar control measured by glycosylated hemoglobin(HgA1c) correlates with T levels in diabetic patients.

Patients and Methods: A retrospective analysis of diabetic patients presenting to urology/andrology clinic for different complains (erectile dysfunction, decrease libido, infertility, lower urinary tract symptoms) all had T and HbA1c measured. Treated hypogonadism and hyper gonadotropic hypogonadism were excluded from the study.

Results:815 patients were included in this analysis with median age of 48 (20-83). Fifty patients hade type 1 DM while 765 had type 2 DM. The mean body mass index (BMI) was 30(16.7-54.4.) 368 patients (45%) were hypertensive. The mean T level was 4.2 ng/ml(0.9-13.8).The mean HgA1c was 8%(5-14), Interestingly a significant number of patients presented with undiagnosed diabetes ( 7 type 1,14%,and 83 type2,11%).T levels were not correlated with HgA1c, type of DM, duration of being diabetic or type of therapy(insulin, no therapy or oral).Also associated comorbidities were not correlated with T levels in either type of DM.

Conclusion: Testsoterone levels in diabetic men are not linked to blood sugar control.
