MedicalResearch.com Interview with: Dr. Carlos Martinez Institute for Epidemiology, Statistics and Informatics GmbH Frankfurt, Germany, MedicalResearch.com: What is the background for this study? Response: A 10-fold increase in testosterone prescriptions per capita in the United States and a 40-fold increase in Canada in men has occurred over the first decade of this century, mainly for sexual dysfunction and/or decreased energy. Recognised pathological disorders of the male reproductive system remain the sole unequivocal indication for testosterone treatment but there has been increasing use in men without pathological hypogonadism. A variety of studies and meta-analyses have provided conflicting evidence as to the magnitude of the risk of cardiovascular events including venous thromboembolism in men on testosterone treatment. In June 2014, the US Food and Drug Administration and Health Canada required a warning about the risk of venous thromboembolism to be displayed on all approved testosterone products. Studies have reported contradictory results on an association between testosterone use and the risk of venous thromboembolism. The effect of timing and duration of testosterone use on the risk of venous thromboembolism was not studied and may explain some of these contradictory findings.
