[The importance of testosterone in the treatment of metabolic syndrome in men].

Testosterone deficiency syndrome is being seen in increasing percentage of men with middle and old age. Besides the typical deterioration of sexual function there is predisposition to metabolic syndrome and increased risk of cardiovascular diseases. The similarity of the effects of testosterone substitution and the dietary treatment led the authors to a retrospective analysis of patient data treated for testosterone deficiency syndrome. Data on 341 patients aged over 45 years with metabolic syndrome and diabetes, meeting criteria for the diagnosis of testosterone deficiency syndrome were divided into 5 groups: T--testosterone substitution without additional diet, T-Low-Carb--testosterone and low carbohydrate diet, T-Fat-Low--testosterone and low fat diet, Carb-Low--only low carbohydrate diet, Fat-Low--only low fat diet. We analyzed change in body weight, waist circumference, blood pressure, fasting glucose, HbAlc, HDL cholesterol and triglyceride levels within 6 months from the start of observation. The best results of all investigated parameters were obtained in patients treated with testosterone and low-carbohydrate diet and in the group treated with testosterone and low-fat diet. Slightly worse results in the group received the same diets and the worst in the group treated only with testosterone. The improvement obtained in the total testosterone therapy and diet was much greater than the simple sum of the effects of both methods witch suggests the existence of synergies.
