Good news, guys: new research from the Cancer Council Victoria in Australia shows that frequent masturbation could protect against prostate cancer. While previous studies indicated that a high frequency of sexual intercourse raised the risk of prostate cancer, the Australian researchers found that the more men ejaculate between the ages of 20 and 50, the less likely they are to develop prostate cancer. Looks like you're better off solo, boys. The greatest protective effect occurs in a man's twenties - those who ejaculated more than five times a week were a third less likely to develop prostate cancer later in life. The research team speculates that frequent ejaculation flushes carcinogens from the prostate gland. So why are you still reading this when there's an internet full of smut to explore?
