Low Free Testosterone and Prostate Cancer Risk: A Collaborative Analysis of 20 Prospective Studies

ConclusionsMen with low circulating free testosterone may have a lower risk of overall prostate cancer; this may be due to a direct biological effect, or detection bias. Further research is needed to explore the apparent differential association by tumour grade.Patient summaryIn this study, we looked at circulating testosterone levels and risk of developing prostate cancer, finding that men with low testosterone had a lower risk of prostate cancer.
