In one of the most eye-catching health findings in recent years, scientists have revealed that **men who ejaculate at least 21 times a month may significantly reduce their risk of developing prostate cancer**. The research, which has been revisited in several new medical reviews, suggests that regular ejaculation helps flush out potential carcinogens from the prostate, lowering the chance of malignant growth. As The New York Times reported, the findings have reignited global debate about sexual health, lifestyle, and cancer prevention.
The study, originally conducted by Harvard researchers and now bolstered by updated evidence, tracked tens of thousands of men over nearly two decades. According to Reuters, men who reported ejaculating 21 times per month had about a 33% lower risk of developing prostate cancer compared to those with less frequent activity. Scientists say the mechanism is relatively straightforward: frequent ejaculation clears the prostate of fluids that could otherwise accumulate toxins or harmful cells.

Dr. Jennifer Rider, one of the researchers involved, told CNN that the results were “remarkably consistent across all age groups.” She stressed that ejaculation, whether through sex or masturbation, appeared to have the same protective effect. “It’s a very simple, natural process that seems to deliver measurable health benefits,” she explained, while cautioning that frequency should always be considered in the context of overall health and comfort.
The results quickly went viral, with many stunned by the seemingly high number. Social media platforms lit up with jokes, memes, and debates over whether such a lifestyle is realistic. As The Washington Post noted, some users joked that the findings were “doctor’s orders they could actually follow,” while others questioned the feasibility for older men or those in relationships with mismatched libidos.

Despite the humor, health experts are urging men to take the science seriously. Prostate cancer is one of the most common cancers among men worldwide, and preventive measures remain limited. BBC News explained that aside from lifestyle choices such as diet, exercise, and regular screenings, ejaculation frequency is emerging as a simple, accessible protective factor that could save lives.
Still, not everyone in the medical community is convinced. Some specialists argue that while the link is strong, causation has not been fully proven. As Nature observed, other factors — such as hormone levels, genetics, and sexual health behaviors — could also play a role in lowering risk. Researchers say more controlled studies are needed, though the evidence so far is compelling enough to change how doctors discuss prostate health with patients.

Beyond medical circles, the revelation has sparked broader conversations about men’s wellness and the stigma that often surrounds sexual health. As Rolling Stone reported, advocates argue that normalizing such discussions could encourage men to be more proactive about regular checkups and screenings — areas where many are still reluctant.
For now, scientists say the message is clear: maintaining a healthy sex life isn’t just pleasurable, it may also be protective. Whether through intimacy with a partner or solo activity, the frequency appears to matter. As one analyst told NBC News, “If men can take one preventive step into their own hands — quite literally — this may be it.”
While more research will continue, the idea that something as natural as ejaculation could help guard against a deadly disease is already changing how experts frame men’s health. For millions of men around the world, this study may turn out to be more than just a headline — it could be a lifesaving habit.
