All over the media, we see No Nut November, pushing abstenance for the month with all of these ideas of what a man will benefit from if they particiapte. Media especially tells us No Nut November is important for men's health. Does science agree? We break it down for you.
Every November, social media explodes with posts about “No Nut November” (NNN)—a viral challenge where participants abstain from ejaculation for 30 days. Proponents claim benefits ranging from increased testosterone to improved self-control and mental clarity. But what does the science actually say? Spoiler alert: abstaining from ejaculation isn’t the health hack it’s marketed to be.
A comprehensive 2025 study published in the Journal of Sexual Medicine examined the claims surrounding No Nut November and found no scientific evidence supporting health benefits from temporary sexual abstinence. The research concluded that abstinence shows neither significant health benefits nor harms for most individuals.
According to Healthy Male Australia, a leading men’s health organization, “There is currently no evidence of any health benefits of No Nut November, or any benefits of not masturbating.” The medical consensus is clear: the purported benefits are largely anecdotal and not supported by rigorous scientific research.
Here’s where the science gets interesting—and contradicts NNN claims entirely. Multiple large-scale studies have found that frequent ejaculation is actually associated with reduced prostate cancer risk.
A landmark 2016 Harvard study published in European Urology found that men who ejaculated 21 or more times per month had approximately 20-31% lower risk of prostate cancer compared to those who ejaculated only 4-7 times per month. This was consistent across different age groups.
The Harvard T.H. Chan School of Public Health research tracked nearly 32,000 men over 18 years and found compelling evidence: “The more frequently ejaculation occurs without risky sexual behavior, the lower the prostate cancer risk appears to be.”
Research published in 2025 in the journal Cancers reinforced these findings, stating: “There is considerable evidence to suggest that frequent ejaculation reduces the risk of prostate cancer.
”Even the Mayo Clinic acknowledges this connection, noting that “some studies have suggested that men with a higher frequency of ejaculations may have a slightly lower risk of prostate cancer.”
