Men Should Masturbate At Least 21 Times A Month, According To Harvard

men should masturbate at least 21 times a month, according to harvard

Researchers from the world's top educational institution have said it themselves: ejaculating 21 times a month can reduce their risk of developing prostate cancer.

Prostate cancer affects one out of every seven men in the United States at some point in their lives. Over the age of 65, the risk increases significantly, with over 85 percent of cases diagnosed in this age group.

Between 1992 and 2010, researchers from Harvard analyzed 31,925 males, asking them about their average monthly ejaculation habits, and the results were published in European Urology in 2016.


The average monthly ejaculation frequency of the males was recorded at three different ages: 20-29, 40-49, and a year before getting the questionnaire.

The report said:

"We evaluated whether ejaculation frequency throughout adulthood is related to prostate cancer risk in a large US-based study."

"We found that men reporting higher compared to the lower ejaculatory frequency in adulthood were less likely to be subsequently diagnosed with prostate cancer."


"These findings provide additional evidence of a beneficial role of more frequent ejaculation throughout adult life in the etiology of PCa [prostate cancer], particularly for low-risk disease."

This Is Not The Only Study In This Field


A team investigated the sexual histories of 840 males at the University of Nottingham. Half of the men got prostate cancer by the age of 60, while the other half did not.

"Frequent masturbation during men's 20s and 30s increased their risk of prostate cancer. But men in their 50s who masturbated frequently had decreased risk," said Polyxeni Dimitropoulou, Ph.D., a member of the research team.


According to the research, men in their 20s were classified as having frequent masturbation two to seven times a week, while men in their 50s had frequent masturbation one or more times a week.

Additionally, men in their 20s who pleasured themselves more than once a month had a 79 percent higher chance of developing prostate cancer by the age of 60, according to the study, than men in their 20s who did so less than once a month.


Compared to men of the same age who did not masturbate at all, men in their 50s who frequently masturbated had a 70% lower risk of prostate cancer.

However, the researchers concluded that masturbation itself isn't the reason for the increased risk of prostate cancer among young men.

According to the study, men are more likely to develop prostate cancer when they naturally produce high male hormones, which increase a man's sex drive.


Dimitropoulou added:

"In mature age, it may be more important that toxins get flushed out of the system."

"And because the masturbation frequency was not as high in the men's 50s as it was in their 20s, even low levels of masturbation in the 50s have a protective effect."

The findings of this research have been published in BJU International.

The bottom line is you can't expect to be OK just by ejaculating a lot.


A healthy diet, frequent exercise, and regular checks with a doctor all help lower your risk, combining all of these to lead the healthiest life possible!
