Did you know that by having at least four orgasms a week, a man's chances of prostate cancer are reduced?

Two large studies, reported in 2003 and 2004, found that middle-aged men who had (or at least remember having) at least four orgasms a week throughout their 20s, 30s and 40s had a reduced risk of prostate cancer by as much as one-third.

Some researchers speculate that ejaculations may clear the prostate of carcinogens.
