Ashok Yadav: Can Frequent Ejaculation Reduce the Risk of Prostate Cancer?

Ashok Yadav, Biology faculty at Apex Academy, shared a post on LinkedIn:

“While frequent ejaculation is linked to a lower risk of prostate cancer, it is not a ‘magic number’ or a medical requirement for everyone. This figure comes from a large, long-term Harvard University study that followed nearly 32,000 men over 18 years.

Key findings from the research include:

Reduced Risk: Men who reported ejaculating 21 or more times per month had approximately a 20% to 33% lower risk of being diagnosed with prostate cancer compared to those who reported only 4 to 7 times monthly.
Ages of Benefit: The study observed these benefits in men during their 20s and 40s, with some evidence suggesting the protective effect may be even stronger for men aged 50 and older
The ‘Flushing’ Theory: Scientists hypothesize that regular ejaculation may help ‘flush’ the prostate of potentially cancer-causing toxins and inflammatory agents that can accumulate in the prostatic fluid.
Method Doesn’t Matter: The frequency counts included all forms of ejaculation, whether through sexual intercourse, masturbation, or nocturnal emissions.

Important Context:

Medical experts at the Mayo Clinic and other institutions caution that this research shows an association, not a direct cause-and-effect proof. Other factors such as genetics, diet, and general lifestyle habits also play critical roles in prostate health. For instance, a diet low in red meat and high in vegetables, regular exercise, and not smoking are also strongly recommended.”
