21! That’s the magical number to lower risk of getting prostate cancer, according to research conducted by Harvard University’s Jennifer R. Rider, which was published in the journal European Urology.
Obviously diet, exercise and regular medical checkups are among the most effective ways of maintaining prostate health but it’s nice to know masturbation has benefits beyond a gooey happy ending.
The study looked at the sexual behaviors of nearly 32,000 men. Participants completed a questionnaire about their ejaculation frequency back in 1992. The men were then followed until 2010. Results revealed that ejaculating at least 21 times a month significantly reduces the risk of prostate cancer in men aged 20-to-29 and 40-to-49.
“We found that men reporting higher compared to lower ejaculatory frequency in adulthood were less likely to be subsequently diagnosed with prostate cancer. This large prospective study provides the strongest evidence to date of a beneficial role of ejaculation in the prevention of prostate cancer.”
