The putative mechanisms underlying testosterone and cardiovascular risk [v1; ref status: indexed, http://f1000r.es/374]

Abstract

The use of testosterone supplementation therapy (TST) is increasing primarily in men with symptomatic hypogonadism. While TST has been shown to have numerous benefits, as its use increases, the role on cardiovascular health must be explored. Previous evidence showed no adverse cardiovascular risks associated with TST use; however, more recent studies suggest that there may be an associated risk. The exact mechanism by which TST may contribute to cardiovascular risk has not been elucidated. Numerous mechanisms have been proposed which include testosterone’s effect on thromboxane A2 receptors, vascular adhesion molecule 1 receptors, erythropoiesis, and obstructive sleep apnea, all of which can ultimately lead to atherogenesis and increased cardiovascular risk.
