Testosterone Therapy Does NOT Increase Prostate Cancer Risk

Published: September 29, 2012

This overview of the scientific literature looked at studies of men receiving therapeutic testosterone for low testosterone levels. Forty four met inclusion criteria: 11 placebo-controlled, randomized studies; 29 non-placebo-controlled studies of men with no prostate cancer history; and 4 studies of men with low testosterone levels with a history of prostate cancer. None showed that the testosterone therapy increased prostate cancer risk or increased the severity of already present cancer in treated vs untreated men.
