For years, conversations about masturbation have been surrounded by myths, warnings, and conflicting advice. Some people claim it should be limited, while others believe avoiding ejaculation for long periods can improve testosterone or fertility.
But now, researchers may have uncovered an unexpected benefit linked to regular ejaculation — and the findings are challenging some long-standing beliefs.
Recent scientific reviews suggest that frequent ejaculation may actually support healthier sperm, rather than harm it.
The Debate Around Abstinence and Sperm Health
Over the years, countless theories have circulated online about how often men should masturbate and whether “holding in” ejaculation can improve overall health.
Movements like “No Nut November” helped popularize the idea that avoiding ejaculation could increase testosterone levels or dramatically improve sperm quality. However, many medical experts have repeatedly questioned those claims.
Some health professionals have even warned that long periods without ejaculation may negatively affect mental well-being for certain individuals, potentially contributing to stress, frustration, or anxiety.
Now, newer research is adding another layer to the discussion.
What Researchers Found
A large review conducted by researchers connected to the University of Oxford analyzed 115 different studies involving nearly 55,000 men.
The researchers examined several important sperm-health factors, including:
- Sperm motility (how effectively sperm move)
- Sperm viability (how many sperm remain alive)
- DNA integrity
Their findings pointed toward a surprising pattern.
Men who went longer periods without ejaculation often showed poorer sperm quality overall. In many cases, sperm movement and viability declined, while levels of DNA damage appeared to increase.
In simple terms, sperm that remain stored for extended periods may begin to deteriorate over time.
Why Frequent Ejaculation May Help
Researchers believe there could be several explanations behind these results.
One possible factor is oxidative stress — a process that can gradually damage cells if older sperm remain stored too long.
Another theory involves energy depletion. Sperm cells are highly active, and prolonged storage may reduce their ability to function effectively when needed.
Regular ejaculation may help the body “refresh” its sperm supply by clearing out older cells and replacing them with newer, healthier sperm.
This doesn’t necessarily mean more is always better, but the findings suggest that moderate, regular ejaculation is unlikely to be harmful for most healthy adults — and may even offer certain benefits.
Earlier Studies Found Additional Benefits
This isn’t the first research to connect regular ejaculation with positive health outcomes.
A previous Harvard study attracted attention after researchers found that men who ejaculated more frequently had a lower risk of prostate cancer.
According to the study, men who ejaculated 21 times or more per month showed a significantly reduced prostate cancer risk compared to those who ejaculated less often.
Researchers emphasized that the results remained consistent even after accounting for various lifestyle factors.
Separating Myths From Science
Despite the growing amount of research, experts continue to stress that sexual health is highly individual. What’s considered “normal” can vary greatly from person to person.
Scientists also caution against relying too heavily on internet trends or viral challenges when it comes to health decisions.
The latest findings don’t suggest that masturbation is a cure-all, nor do they mean abstinence is automatically harmful for everyone. Instead, they highlight that the human body may function best with balance rather than extremes.
As research continues, one thing is becoming increasingly clear: many of the old myths surrounding masturbation and sperm health may not hold up under scientific scrutiny after all.
