    Frequent sex: Does it protect against prostate cancer?

    By Mayo Clinic Staff

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

    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.
