Study Finds Link Between Ejaculation Frequency and Risk of Prostate Cancer

Many studies have associated regular ejaculation during sex, masturbation, or while sleeping with a decreased risk of prostate cancer!

The journal of European Urology published a study in 2016 saying that ejaculation makes a difference in preventing prostate cancer.

As part of Harvard’s Health Professionals, a follow-up study examined 29,342 men with ages between 46 and 81. Researchers asked participants to state their average number of ejaculations per month in their young adulthood (ages 20–29), in mid-life (ages 40–49), and in the most recent year. Ejaculations included sexual intercourse, nocturnal emissions, and masturbation. Study participants also provided comprehensive health and lifestyle data every two years from 1992 to 2000. And the researchers discovered that participants who ejaculated at least 21 times per month during their young adulthood had 33% less chance to develop prostate cancer than those participants who ejaculated 4 to 7 times per month. They also found that men who frequently ejaculate during their 40s could reduce their prostate cancer risk by 22%.

This study regarding the correlation between ejaculation and prostate cancer is nothing new. In 2003, a team of Australian scientists examined ejaculation frequency among 2,338 men, where half of the participants were diagnosed with prostate cancer.

The results revealed that men who ejaculate 4.6 to 7 times per week had 36% less chance to develop prostate cancer before the age of 70 than in comparison to men who ejaculated less than 2.3 times per week. Also, an earlier study observed that men who had sex with 30 or more women in their life had two to three times more chance to develop prostate cancer than men with only one partner.

Even though the results have been constant, scientists are not entirely sure about why ejaculating could relate to a reduced risk of prostate cancer.

Ejaculation does appear to be a measure of overall health in men as the men in the studies who were at the lower end of ejaculation spectrum, such as zero to three times per month, were expected to experience other medical problems and die earlier from causes other than prostate cancer.


In theory, releasing the prostate of potentially irritating or harmful substances might be one such mechanism. Regardless of the reason why ejaculation might help to prevent prostate cancer or not, take comfort in the fact that ejaculation is not only pleasurable but also may carry several positive health benefits.
