Study reveals how many times a man should ejaculate per month to help prevent prostate cancer

A Harvard study has revealed that frequent ejaculation may significantly reduce the risk of developing prostate cancer—a disease that affects one in eight men and is the second-leading cause of cancer death among men in the U.S.

The 2016 study, published in European Urology, tracked 31,925 men over nearly two decades. Researchers found that men who ejaculated at least 21 times per month had a 20% lower risk of developing prostate cancer compared to those who did so less frequently.

“Higher ejaculation frequency in adulthood was associated with lower prostate cancer risk,” the study noted, especially for low-risk disease.
