Okay, the blind part is a joke. But scientists think regular masturbation helps men reduce the risk of prostate cancer. The same is not true for regular intercourse though.

Australian researchers came to the conclusion form a survey of 1,000 men with prostate cancer and 1,250 healthy men. They found men between 20 to 50 years of age with frequent ejaculation were least likely to have the cancer. It is more effective for younger men in their 20’s, and a frequency of more than five times a week reduced the risk of prostate cancer by a third. They think ejaculation helps men flush out the cancer-causing chemicals that accumulate in the prostrate glad. One such chemical is 3-methylchloranthrene, also found in cigarette smoke. However, frequent intercourse with multiple partners actually increases the risk by 40% due to the increased risk of STIs.

This is similar to the connection between breast cancer and lactation: breastfeeding also helps to get rid of cancer causing chemicals in women.
