Sexual activity frequency linked to lower prostate cancer risk, study finds

A large U.S. cohort study found men who ejaculate 21+ times per month had about a 20% lower risk of being diagnosed with prostate cancer than those who ejaculate 4–7 times monthly, with the strongest effect seen in low-risk tumors. The association does not prove causation, and ejaculation should not replace regular screening or other healthy habits—diet, exercise, and avoiding smoking—when assessing overall prostate cancer risk.
