The Research on Ejaculation and Risk Reduced Risk: Several large-scale studies, including one from the Harvard School of Public Health, have found a consistent association between a higher frequency of ejaculation and a lower risk of prostate cancer.
The "Magic Number": One notable study found that men who ejaculated 21 or more times per month had approximately a 20% lower risk of prostate cancer compared to those who ejaculated 4 to 7 times per month.
The Method Doesn't Matter: The reduction in risk appears to be related to the act of ejaculation itself, regardless of whether it occurs during sexual intercourse or masturbation. Proposed Mechanisms (Why it Might Help)
Experts are not entirely sure why frequent ejaculation might be protective, but the leading theories include:
Flushing out Carcinogens: Ejaculation may help flush out old fluid and potentially harmful, cancer-causing substances (carcinogens) that can build up in the prostate gland.
Reducing Inflammation: Ejaculation may help reduce inflammation in the prostate, and chronic inflammation is a known factor in cancer development.
Important Caveats Correlation, Not Causation: The studies show a correlation (a link) but do not definitively prove that frequent ejaculation causes the risk reduction. It is possible that men who ejaculate more frequently also have other healthy lifestyle factors that are responsible for the lower risk. No Guarantee: Ejaculation is not a proven, guaranteed prevention strategy. Major risk factors like age, family history, and race/ethnicity remain the primary determinants of prostate cancer risk.
Also, it's been shown that testosterone facilitates the growth of cancer cells, and increased sexual activity increases testosterone, hence may also help in the metastasis of cancer to other parts of the body. In other words, take this with a grain of salt.
