United States - April 27th, 2007: It’s no news that masturbation may reduce the risk of prostate cancer, since many researches around the world already confirmed the fact.
However, the theory that becomes more and more supported by scientists and clinicians is that masturbation is definitely more effective for cancer prevention than sexual intercourse. Accordingly to specialists, ejaculating periodically may reduce the risk of prostate cancer since it “cleans out” the organ, eliminating carcinogens building up in the gland. However, during intercourse there is a strong exchange of microorganisms through the genitals, what may cause infections (sometimes very subtle and imperceptible, harmless in short term). Through life, these infections may actually increase the risk of prostate cancer.
During masturbation however, a man may “flush the ducts out” without interacting with pathogenic agents from other individuals, what makes the ejaculation more effective in prevention. Further researches are being made, focusing on the number of ejaculations and whether if they are resulted from masturbation or intercourse. Previous studies only took the frequency of ejaculation into account.
