The relationship between ejaculation frequency and prostate health is a topic of ongoing research, but current evidence suggests that regular ejaculation may be associated with a lower risk of prostate cancer. However, declaring a daily frequency as universally “good” is an oversimplification.

Here is a summary of key findings from notable studies:

Potential Protective Effect: A prominent 2016 study in European Urology found that men who ejaculated 21 or more times per month had a significantly lower risk of prostate cancer compared to those with 4-7 ejaculations per month. This correlation does not prove causation, but it points to a potential benefit of regular sexual activity.
Mechanism Theories: Hypotheses for this link include the flushing out of cancer-causing substances, reducing stagnation of prostatic fluid, or lowering psychological stress.
Not a Guarantee or Prescription: This research should not be interpreted as a medical directive. Factors like age, overall health, genetics, and lifestyle play a far more significant role in prostate health. There is no established medical consensus that prescribes a specific ejaculation frequency for prostate wellness.

Consult a Healthcare Professional: For personalized advice on prostate health including the appropriateness of PSA screening, symptom evaluation, or risk reduction—consulting a urologist or primary care physician is essential.
