I have found an interesting post which can be interesting for older masturbators.
Frequent ejaculation protects against prostate cancer
Bethesda / Maryland (pte) - According to an American study with more than 30,000 subjects, it seems clear that frequent sexual intercourse and masturbation are obviously protecting against prostate cancer. The study, conducted by researchers of the National Cancer Institute in Bethesda over a period of eight years, was actually aimed at questioning the theory that too often sex leads to prostate cancer, reports the science magazine New Scientist http://www.Newscientist.com. The results of the large-scale US study, conducted by Michael Leitzmann and his team, testify to a study by Australian researchers. This also concluded in July 2003 that frequent ejaculation was obviously protecting against prostate cancer. Thus, men ejaculated about 21 times a month developed a third of rare prostate cancer as the reference group, who had ejaculation about four to seven times a month. In the American study, thousands of healthy men were first questioned, then cancer patients, whose sexual habits were subsequently retrospectively evaluated. At the start of the study, men were questioned with questionnaires about the frequency of their ejaculation. These questionnaires were issued every two years. "When the ejaculation frequency is increased from four to seven times a month to three ejaculations a week, the rate of cancer is decreasing by 15 percent," says Leitzmann, who, however, refrains from changing men's sexual behavior. However, the researchers see several reasons for the advantage of frequent ejaculations: the prostate gland is cleansed by ejaculation. In addition, ejaculation also ensures that crystalline microcalcifications can not form. These are also associated with the development of prostate cancer. However, Graham Giles, author of the Australian study, argues that the ejaculation frequency of teenagers was not included in either study. Perhaps there is already a key here for the formation of prostate cancer. "Further studies need to be followed, but one thing seems clear in both studies: orgasms are not dangerous and protect against prostate cancer".
