From Pleasure to Protection: Why Sex May Prevent Prostate Cancer

Engaging in sexual activity that includes ejaculation, with or without a partner, has been associated with potential benefits for prostate health, although it is important to note that research in this area is ongoing and not all studies show consistent results.

Some studies suggest that men who ejaculate more frequently may have a lower risk of developing prostate cancer. In Spain, the CAPLIFE study reported in 2023 that ejaculating less frequently was associated with a higher risk of prostate cancer.

Currently, the strongest evidence regarding ejaculation frequency and prostate cancer risk is an ongoing long-term study by the Harvard T.H. Chan School of Public Health, the Health Professionals Follow-Up Study. In 2016, it was reported that after 18 years of follow-up on 31,925 US male health professionals that men who ejaculated more frequently in adulthood were less likely to be diagnosed with prostate cancer. Those who ejaculated at least 13 times per month were around 25% less likely to be diagnosed with low-risk prostate cancer, as compared to those who only ejaculated 4 to 7 times per month.

This could potentially be explained by the prostate stagnation hypothesis. This theory proposes that the accumulation of potentially carcinogenic substances in the prostate may contribute to the development of prostate cancer. It is suggested that ejaculation can help to clear these substances, preventing an inflammatory environment from forming, in order to reduce the risk of prostate cancer.

It is crucial to note that while there is some evidence suggesting a potential link between sexual activity and prostate health, correlation does not imply causation. Other factors, such as genetics, diet, exercise, and overall lifestyle, also play significant roles in prostate health and cancer risk. It also seems that more frequent sexual activity does not protect against advanced or aggressive prostate cancers.

Moreover, individual experiences and health conditions vary, so what may be beneficial for one person might not be the same for another. If you have concerns about your prostate health, it is important to consult with a healthcare professional who can provide personalized advice and recommendations based on your specific circumstances.
