The safety of testosterone supplementation therapy in prostate cancer

Historically, the use of testosterone supplementation therapy (TST) for hypogonadism in men with prostate cancer has been limited by concerns that such treatment might cause progression of this androgen-dependent cancer; however, the contemporary literature indicates that TST in men with prostate cancer can be safe and, contrary to traditional thinking, that TST might actually reduce the risk of prostate cancer development. In this opinion piece, Larry Lipshultz and colleagues discuss the evidence supporting TST—in contrast with the lack of evidence against this approach—in hypogonodal men with prostate cancer.
