Sleeping with many women may reduce your risk of Prostate cancer.

In a new study published in the journal Cancer Epidermiology, researchers from the Universite de Montreal found that compared to men who have had only one partner during their lifetime, having sex with more than 20 women is associated with a 28% lower risk of being diagnosed with Prostate cancer.

3,208 men were sampled in the study. Of these men, 1,590 were diagnosed with prostate cancer between September 2005 and August 2009, while 1,618 men were part of the control group.

Overall, researchers found that men with prostate cancer were twice as likely as others to have a relative with cancer. However, evidence suggests that the number of sexual partners affects the development of the cancer.

When a man has slept with more than 20 women during his lifetime there is a 28% reduction in the risk of having prostate cancer (all types), and a 19% reduction for aggressive types of cancer.

According to some studies, the underlying mechanism of this protective effect is in reducing the concentration of cancer-causing substances in prostatic fluid or lowering the production of intraluminal crystalloids.
