It's official, Protein is good for you, well masturbation to be exact. We're not making this up, New Scientist says so, so it's *got* to be true. New research indicates that the more often men ejaculate between the ages of 20 and 50, the less likely they are to develop prostate cancer. The greatest protective effect comes in a man's twenties - those who ejaculated more than five times a week were a third less likely to develop aggressive prostate cancer later in life. One possible explanation for the effect is that frequent ejaculation flushes carcinogens from the prostate gland. A team in Australia led by Graham Giles of The Cancer Council Victoria in Melbourne asked 1079 men with prostate cancer to fill in a questionnaire detailing their sexual habits, and compared their responses with those of 1259 healthy men of the same age. The team concludes that the more men ejaculate between the ages of 20 and 50, the less likely they are to develop prostate cancer. The protective effect is greatest while men are in their twenties: those who had ejaculated more than five times per week in their twenties, for instance, were one-third less likely to develop aggressive prostate cancer later in life (BJU International, vol 92, p 211).
