Effects of Testosterone Replacement Therapy on Metabolic Syndrome in Male Patients-Systematic Review
Abstract
Metabolic syndrome (MS) comprises several symptoms or disorders that significantly increase the risk of developing atherosclerosis and type 2 diabetes. This study aims to determine the direct impact of testosterone therapy on the components of MS; although excluding type 2 diabetes cases. The authors conducted a systematic literature search of PubMed, Scopus, and Cochrane databases without date limits, using keywords such as "testosterone therapy", "metabolic syndrome" and "men". The studies included in our review focused on the effects of testosterone replacement therapy (TRT) in male patients with MS, yet rejecting individuals where type 2 diabetes constituted the only diagnosis. A meta-analysis was performed using PQStat v1.8.6 software. The overall effect size (mean difference) was calculated using a random effects model. Our meta-analysis indicates that testosterone therapy leads to improvement in the components of MS. Significant reductions were observed in waist circumference (WC) (95% CI: -0.709 to 0.094; p = 0.011), as well as in triglycerides (TG) (95% CI: -0.474 to 0.120; p = 0.039). These findings support the potential therapeutic benefits of testosterone treatment in managing MS. However, further research is vital to explore the long-term effects and the safety of this therapy in patients with metabolic syndrome.
