Vasectomy may increase risk of aggressive prostate cancer
Date:7/9/2014

cer was 56%. The effect appeared to be stronger among men who had a vasectomy at a younger age.

Prior work on this topic raised concerns that the positive associations could be linked to bias. However, in the present study, the researchers had access to diverse information and could rule out potential biases, including that men who have vasectomies may seek more medical care in general, that they may have a higher rates of PSA screening, or that the association was due possible confounding by sexually transmitted infections.

In this study, 16 in 1,000 men developed lethal prostate cancer during 24 years of follow-up. Although the relative increase in the risk associated with vasectomy was significant, this translates to a relatively small increase in absolute difference in the risk of lethal prostate cancer, say the researchers. "The decision to opt for a vasectomy as a form of birth control is a highly personal one and a man should discuss the risks and benefits with his physician," said co-author Kathryn Wilson, research associate in the Department of Epidemiology at HSPH.
