Cancer de la prostate : Éjaculer fréquemment aide-t-il à se prémunir ? Ce que disent les études
Prostate cancer, the most common cancer in men after age 50, is driving research to explore new avenues for prevention. Recent scientific studies highlight a surprising trend: the frequency of ejaculation may play a protective role.
Key figures from the studies
Major research, including the Health Professionals Follow-Up Study (published in JAMA in 2004), has observed a link between regular sexual activity and a reduced risk of cancer. Men who ejaculate 21 times or more per month showed a significantly lower risk of prostate cancer.
This protective effect is particularly noted in men with this high frequency between the ages of 20 and 29, as well as 40 and 49, compared to those ejaculating 4 to 7 times per month.
Researchers propose two hypotheses to explain this effect: the regular elimination of potentially harmful substances and the stimulation of prostate tissue.
Professor Racine Kane's opinion
Urologist Professor Racine Kane confirms this trend, while urging caution. "Frequent ejaculation is not a miracle cure, but it seems to have a protective effect on the prostate," explains the surgeon.
He insists that ejaculation is one factor among others and does not replace essential preventive measures: regular screening, balanced diet, physical activity and medical follow-up.
Contrary to some misconceptions, reducing the frequency of ejaculation offers no protection. On the contrary, data suggests that a regular sex life could help limit the risk of prostate cancer, in addition to a healthy lifestyle and consistent medical monitoring.
