Sex reduces prostate cancer risk

Frequent ejaculations, especially in 20-something men, may reduce the risk of prostate cancer later in life, and men who had five or more ejaculations weekly while in their 20s reduced their risk of getting prostate cancer later by a third.  Frequent ejaculations, up to 21 or more a month, were linked to lower prostate cancer risk in older men, as well, compared with less frequent ejaculations of four to seven monthly.
