The subject is very delicate, and few men talk about it, whether openly or privately with their partners or friends. However, despite the discomfort associated with the topic of ejaculation, research urges us to publish this information, especially since the evidence is clear: ejaculation prevents prostate cancer!
A rumor had circulated for many years, claiming that masturbation was beneficial for the prostate. However, it is not so much masturbation itself that is beneficial, but rather ejaculation, although one is often linked to the other. Three credible university studies conducted in recent years confirm that ejaculation is not only beneficial against prostate cancer but also helps regenerate certain prostate cells.
What is the exact mechanism of ejaculation?
According to the National Institutes of Health (NIH) in the United States, ejaculation is a complex process involving several bodily systems. It begins in the brain, where nerve signals are sent in response to sexual stimulation. This activates the sympathetic nervous system, which is responsible for involuntary reactions. These signals trigger the contraction of smooth muscles in the vas deferens, prostate, and seminal vesicles, pushing sperm and seminal fluid into the urethra. Then, rhythmic contractions of the pelvic muscles allow for the expulsion of sperm through the urethra and out of the body.
The National Library of Medicine
In 2016, the National Library of Medicine published the study « Ejaculation Frequency and Prostate Cancer Risk, » concluding: These results provide additional evidence of the beneficial role of more frequent ejaculation throughout adult life in the etiology of prostate cancer, particularly for low-risk forms. We evaluated whether ejaculation frequency throughout adulthood is related to prostate cancer risk in a large US-based study. We found that men reporting a higher ejaculation frequency compared to a lower frequency in adulthood were less likely to be subsequently diagnosed with prostate cancer.
Boston University
In 2018, Boston University published the study « Ejaculation Changes Prostate Tissue, Lowering Cancer Risk » in its journal The Brink, concluding: The study, published in European Urology, finds evidence that more frequent ejaculations affect the expression of 409 genes and six biological processes. The study may support the “prostate stagnation hypothesis,” where carcinogens accumulate in the prostate between ejaculations and affect cells’ genome and metabolic processes. Next, focusing on ejaculation frequency in 1991, the researchers found associations with six different biological processes at the cellular level. The most significant association was with ubiquitin-mediated proteolysis, which is involved in cell cycle regulation. The researchers also noted an association between higher rates of ejaculation and cells producing and exporting more citrate, a component of semen, because lower citrate production is a distinguishing feature of prostate cancer.
Harvard University
Finally, in 2022, Harvard Medical School published the research « Ejaculation Frequency and Prostate Cancer, » concluding: Scientists found no evidence that frequent ejaculations increase the risk of prostate cancer. In fact, the reverse was true: high ejaculation frequency was linked to a decreased risk. Compared to men who reported 4 to 7 ejaculations per month throughout their lives, men who ejaculated 21 or more times per month enjoyed a 31% lower risk of prostate cancer. Moreover, the results held up to rigorous statistical evaluation even after accounting for other lifestyle factors and the frequency of PSA testing.
Conclusion
It is undeniable that we are no longer in the realm of rumor, and medical research confirms that ejaculation helps expel carcinogenic substances. The higher the frequency of ejaculations, the better the results regarding prostate cancer.
Another fact derived from this research allows us to conclude that ejaculation is even more effective than any other preventive treatment, vitamins, or medications. If the subject makes you uncomfortable and you are not at ease discussing it with your partners or friends, as it often requires working on the issue « in solitude, » you can seek advice from your family doctor or any social worker, for whom questions related to sexuality are quite mundane.
