Men who have a vasectomy may be at increased risk for aggressive prostate cancer, a new study suggests.

But the risk is comparatively small, the researchers acknowledged. And several urologists not involved with the study said more research is needed to determine if the study findings are truly accurate.



For the study, Harvard researchers analyzed data from more than 49,400 American men who were followed for 24 years, starting in 1986. During that time, 6,023 cases of prostate cancer were diagnosed among the men, including 811 fatal cases.
