Doctor’s Insight: How Ejaculation Frequency May Affect Prostate Cancer Risk
Several medical studies suggest that regular ejaculation may help reduce the risk of prostate cancer, though the exact mechanism is still being researched. Here’s what science says:
Key Findings from Research:
-
A 2016 Harvard study found that men who ejaculated 21+ times per month (about 5 times a week) had a ~33% lower risk of prostate cancer than those who did so 4–7 times per month.
-
Another study in the British Journal of Urology International supported this, linking higher ejaculation frequency to a reduced risk of prostate cancer, possibly due to flushing out carcinogens or reducing inflammation.
-
However, no study proves causation—only correlation. Genetics, diet, and lifestyle also play major roles.
Doctors’ General Recommendations:
-
21+ ejaculations per month (~5x/week) may offer protective benefits.
-
No need to force it—benefits likely come from natural sexual activity (intercourse, masturbation, or nocturnal emissions).
-
Balance is key—excessive frequency doesn’t necessarily mean extra protection.
Other Ways to Support Prostate Health:
✔ Eat a Mediterranean diet (tomatoes, nuts, fatty fish).
✔ Exercise regularly (especially cardio and pelvic floor exercises).
✔ Limit alcohol & smoking (both increase cancer risk).
✔ Get regular checkups (PSA tests if over 50 or high-risk).
Bottom Line:
While frequent ejaculation might lower prostate cancer risk, it’s just one factor. A healthy lifestyle and regular medical screenings are far more critical.
