Men who ejaculate at least 21 times a month may have a 20% lower chance of getting prostate cancer

New Harvard data links high ejaculation frequency to a lower risk of prostate cancer in men.
The Harvard Ejaculation Study followed over 29,000 men from 1986, tracking ejaculation and health updates until 2000.
Even after adjusting for lifestyle factors, the link between frequent ejaculation and lower cancer risk held up.
Experts say the findings suggest a potential biological mechanism, not a guaranteed shield against cancer.
The study involved a broad look at sex, masturbation, and nocturnal emissions to gauge frequency.
The most active group showed a 31 percent lower risk of prostate cancer overall.
Researchers emphasize health habits from earlier life may influence later cancer risk.
The study is observational and does not prove causation between ejaculation frequency and cancer risk.
Harvard researchers stress the need for further research to understand mechanisms behind the link.
The Health Professionals Follow-Up Study is a well-known long-term health survey started in 1986.
