Cardiovascular safety of testosterone therapy-Insights from the TRAVERSE trial and beyond: A position statement of the European Expert Panel for Testosterone Research.

Abstract

Introduction: Testosterone therapy has become a cornerstone treatment for men with hypogonadism, offering significant benefits such as improved sexual function, mood, muscle mass, and bone density. However, concerns about its cardiovascular safety have historically tempered its use. This position statement synthesizes the current evidence on the cardiovascular safety of testosterone therapy, drawing from key studies including the TRAVERSE trial, other trials, and recent meta-analyses.

Background and importance: Testosterone therapy aims to restore testosterone levels in men with hypogonadism, a condition associated with increased cardiovascular and metabolic risks. Early research produced mixed results, with some studies suggesting a potential increase in cardiovascular events such as myocardial infarction and stroke, while others indicated possible cardiovascular benefits, particularly in men with coexisting conditions like metabolic syndrome and type 2 diabetes.

Findings from recent studies: The TRAVERSE trial, a large-scale, randomized, placebo-controlled study, provided robust evidence that testosterone therapy does not significantly increase the risk of major adverse cardiovascular events. Testosterone therapy was found to effectively mitigate anemia in hypogonadal men, highlighting a dual benefit of increasing red blood cell production while managing cardiovascular risks. The findings from the TRAVERSE trial align with those from previous meta-analyses that concluded that testosterone therapy is safe and does not increase cardiovascular risk.

Consensus and clinical implications: There is consensus that testosterone therapy, when prescribed to appropriately selected patients and monitored regularly, is safe from a cardiovascular standpoint, with the potential benefits outweighing the risks when the therapy is used responsibly. Current guidelines recommend individualized treatment plans with careful monitoring, especially of hematocrit levels. This position statement amalgamates previous knowledge with current data and is in agreement with recent United States Food and Drug Administration label changes for testosterone products.
