peared to attenuate the negative effect of testosterone on the prostate in that subjects who received the dual regimen had no increase in prostate-specific antigen levels and had a significantly lower increase in prostate volume than those treated with testosterone alone (5). While these data are encouraging, they are based on small patient numbers, and the favorable effects on prostatespecific antigen levels may not necessarily translate to a reduction in prostate cancer risk. In addition, while finasteride was shown to reduce the development of prostate cancer in middle-aged men, the incidence of high-grade prostate tumors and sexual side effects was increased (6).Therefore, I believe that further research is still needed to identify the androgen regimen that confers optimal benefit to older men without compromising prostate health and overall patient safety.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
