Androgen Society Position Paper on Cardiovascular Risk With Testosterone Therapy

Abstract

The Androgen Society is an international, multidisciplinary medical organization committed to advancing research and education in the field of testosterone deficiency and testosterone therapy (TTh). This position paper is written in response to results of the TRAVERSE study, published in June 2023, which reported no increased risk of major adverse cardiovascular events (MACE) in men who received TTh compared with placebo. In 2013-2014, 2 observational studies reported increased cardiovascular (CV) risks with TTh and received wide media attention. Despite strong criticism of those 2 studies, in 2015, the Food and Drug Administration added a CV warning to testosterone product labels and required pharmaceutical companies to perform a CV safety study, which became the TRAVERSE trial. TRAVERSE enrolled 5246 men at high risk for MACE based on existing heart disease or multiple risk factors. Participants were randomized to daily testosterone gel or placebo gel, with a mean follow-up of 33 months. Results revealed no greater risk of MACE (myocardial infarction, stroke, or CV death) or venothrombotic events in men who received TTh compared with placebo. Review of the prior literature reveals near uniformity of studies reporting no increased MACE with TTh. This includes 2 additional large randomized controlled trials, multiple smaller randomized controlled trials, several large observational studies, and 19 meta-analyses. In view of these findings, it is the position of the Androgen Society that it has now been conclusively determined that TTh is not associated with increased risks of heart attack, stroke, or CV death.
