How ejaculation helps reduce prostate cancer
An epidemiological study of 30,000 American men by Michael Leitzman, a cancer researcher at the National Cancer Institute in Bethesda, Maryland, has found that men who enjoy an active sex life do not risk prostate cancer in later life.

There has been a suggested link with greater sexual activity and increased incidents of prostate cancer in previous scientific data because of the link with the male hormone testosterone and its effect on promoting cancer cell growth.

Leitzmann's findings were that men who ejaculate between 13 and 20 times a month had a 14% lower risk of prostate cancer that men who ejaculated on average, between 4 and 7 times a month for most of their adult life. Men who ejaculated upwards of 21 times a month had a 33% lower lifetime risk of prostate cancer than the baseline group.

The study of predominantly white professional males would seem to suggest, as Mr Leitzmann himself says, ‘the finding warrant further investigation’.
