For six decades, it has been a part of the conventional medical wisdom that higher levels of testosterone increase the risk of prostate cancer. This belief is mostly derived from the well-documented regression of prostate cancer after surgical or pharmacological castration. However, there is an absence of scientific data supporting the concept that higher testosterone levels are associated with an increased risk of prostate cancer. Moreover, men with hypogonadism have substantial rates of prostate cancer in prostatic biopsies, suggesting that low testosterone has no protective effect against the development of prostate cancer. Moreover, prostate cancer rate is higher in elderly patients when hormonal levels are low. These results argue against an increased risk of prostate cancer with testosterone replacement therapy.
