New research has revealed that there is a certain number of times a man should ejaculate a month to help reduce the risk of prostate cancer.

It turns out that today (July 31) is national orgasm day, and what better way to celebrate than finding out that it could be beneficial to your health to take part.

Science has found a surprising link between frequent ejaculation and a reduced risk of prostate cancer.

That’s right — the more men orgasm, the lower their chances of developing the disease. These findings come at a crucial moment, as projections show global deaths from prostate cancer could double in the next two decades.

So if you were gearing up for No Nut November, you may want to reconsider.


But what is the magic number you should be aiming for? Well, according to science, it's 21 times per month.

According to a study published in European Urology, which followed over 32,000 men for 18 years, those who ejaculated more frequently had a significantly lower risk of developing prostate cancer compared to those who only ejaculated four to seven times a month.

The good news? It doesn’t matter how it happens.

Whether it’s solo play, partnered sex, or even a spontaneous wet dream, the health benefits are still there.

Researchers at Harvard Medical School and Brigham and Women’s Hospital found that daily ejaculation — in any form — can be good for you.

Why this happens is still somewhat of a mystery, but experts have a few theories.

Dr. Anne Calvaresi, chair of the Urology Care Foundation’s Prostate Health Committee, suggests that ejaculation could help flush out harmful chemicals that build up in semen.

She also points out that “it is possible men who ejaculate more may have healthier lifestyle habits that decrease their odds of being diagnosed with the disease.”

It turns out that abstaining from sex can also have a negative impact on your health.

Dr. Tara Suwinyattichaiporn broke it down in an interview with the Daily Mail, highlighting some of the lesser-known consequences of a sexless stretch.

Sex naturally triggers the release of oxytocin, famously known as the "love hormone." This feel-good chemical plays a big role in bonding, trust, and overall mood.

As Dr. Suwinyattichaiporn points out: “Without this dopamine, you can undergo a variety of problems that are detrimental to your mental health such as anxiety, depression, and increased levels of stress.”

It’s not just about missing out on pleasure — sex has a real impact on emotional well-being.

A lack of intimacy can even manifest as anger. According to a 2021 Science Direct study, unmet sexual needs can increase frustration and may lead to aggressive behavior.

The study states that sexual frustration may result in “the risks of aggression, violence, and crime associated with relief-seeking, power-seeking, revenge-seeking, and displaced frustration.”

While the psychological effects are more pronounced, a lack of sex can impact the body too — especially over the long term.

Dr. Suwinyattichaiporn notes that men who abstain for extended periods may face health risks such as penile atrophy and even an increased chance of prostate cancer.

For women, going months without sex can lead to vaginal atrophy — a condition where vaginal tissues become thin, dry, and in some cases, the canal can shorten.

This can make future sexual activity uncomfortable or even painful.
