RÉSUMÉ
Objective@#To evaluate the effects of Testosterone Undecanoate Pills (TUP) on insulin resistance (IR) in type-2 diabetes men with hypogonadism.@*METHODS@#We randomly divided 82 type-2 diabetes patients with hypogonadism into a treatment (n = 42) and a control group (n = 40), both maintaining their glucose- and lipid-reducing therapies, while the former treated orally with TUP in addition. After 6 months of medication, we compared the body mass index (BMI), waist circumference (WC), blood glucose level, HbA1c, lipid profile, IR index obtained by homeostatic model assessment (HOMA-IR), insulin sensitivity index (ISI), sex hormone levels, and sexual function scores between the two groups of patients.@*RESULTS@#Compared with the baseline, the patients in the treatment group showed significant decreases after medication in BMI (［26.71 ± 2.39］ vs ［25.15 ± 2.28］ kg/m2, P 0.05).@*CONCLUSIONS@#TUP can significantly improve insulin resistance in type-2 diabetes men with hypogonadism.
