In an annoucement that brought an erruption of joy and exclamation around the world, The National Cancer Institute has shown that masturbation (and sexual intercourse ejaculation) greatly reduces a man’s risk of prostate cancer.
Plus, it feels good.
Frequent sexual intercourse and masturbation protects men against a common form of cancer, suggests the largest study of the issue to date yet.
The US study, which followed nearly 30,000 men over eight years, showed that those that ejaculated most frequently were significantly less likely to get prostate cancer. The results back the findings of a smaller Australian study revealed by New Scientist in July 2003 that asserted that masturbation was good for men.
In the US study, the group with the highest lifetime average of ejaculation – 21 times per month – were a third less likely to develop the cancer than the reference group, who ejaculated four to seven times a month.
Michael Leitzmann, at the National Cancer Institute in Bethesda, Maryland, and colleagues set out to test a long-held theory that suggested the opposite – that a higher ejaculation rate raises the risk of prostate cancer. "The good news is it is not related to an increased risk," he told New Scientist. In fact, it "may be associated with a lower risk."
Though the above study was conducted in 2004, word is that there is another follow-up study in the pipes. Scuttlebutt has it that NCI had absolutely no problems finding research subjects for this follow-up and had to turn many, many, many men away. (j/k.)
