Is there research to support the theory that frequent ejaculation reduces the risk of prostate cancer?

Answer From Patricio C. Gargollo, M.D.

At this time, there is no conclusive evidence that frequent ejaculation reduces the risk of prostate cancer.

Some studies have suggested that men with a higher frequency of ejaculations may have a slightly lower risk of prostate cancer. However, this difference appears to be very small. Other studies haven't supported this conclusion.
