Does Having More Ejaculations Lessen the Chance of Prostate Cancer?
For reasons not fully known, ejaculating more may lower the risk of prostate cancer.
Ejaculating after all, based upon some studies, through sexual intercourse or masturbation, does not seem to protect against higher risk prostate cancers. The studies do not sort out between ejaculating during sexual intercourse or masturbation, and the effect of each on prostate cancer.
One study followed 32,000 men for 18 years. It found men who ejaculated the most (at least 21 times a month) had a 20% lower chance of prostate cancer vs. those who ejaculated 4 to 7 times a month. The more the number increased per month, the lower their risk. Other studies have found ejaculation rate has no impact on prostate cancer rates.
Ejaculation may protect the prostate by flushing out harmful chemicals that build up in semen. It is also possible ejaculation does not actually protect against prostate cancer. Men who ejaculate more may have healthier lifestyle habits that decrease their odds of being diagnosed with the disease. Additionally, ejaculating may only reduce the risk in men in certain age groups.
The bottom line is more research is needed before we know for sure whether more ejaculation reduces the risk of prostate cancer.
