Effects of long-term testosterone therapy on obesity, glycaemic control and other features of the metabolic syndrome

Epidemiological studies show a high prevalence of hypogonadism in men with obesity, type 2 diabetes and other components of the metabolic syndrome. Restoring physiological concentrations of testosterone in hypogonadal men by long-term testosterone therapy of 5 years and longer has resulted in substantial weight loss and meaningful improvement of glycaemic control. Blood pressure was reduced and lipid pattern improved. The longer the observation time in real-life studies, the more robust the results.

Both magnitude and sustainability of treatment effects, predominantly based on observational studies with and without untreated control groups and a duration of up to 8 years, are of such interest that further studies with an adequate design should be performed. However, conducting placebo-controlled trials over several years in men diagnosed with hypogonadism may not be considered ethical.

A host of studies have shown that adequate testosterone therapy reduces major adverse cardiovascular events and mortality in hypogonadal men. These studies are consistent with the observed beneficial effects of long-term testosterone treatment on the classical cardiovascular risk factors (visceral obesity, hypertension, dyslipidaemia, insulin resistance). In addition, testosterone has anti-inflammatory and anti-coagulatory properties.

According to what is known today, there is sufficient evidence to recommend measuring testosterone in men with obesity and/or type 2 diabetes. If hypogonadism is diagnosed, testosterone therapy should be considered. Adequate therapy, i.e. restoring testosterone levels to the mid- to high normal range for life seems the most promising approach. Medication adherence, as in all chronic diseases, is essential.
