Prostate cancer is the most common cancer in men in many parts of the world, and yet it remains one of the least talked about. At TLC – Tracy Louise Clinic, we believe that open, evidence-based conversations, education about men’s health are important. So today, we’re delving into a topic that’s been making headlines, and for good reason.
What the Research Shows
A landmark study led by researchers at Harvard’s T.H. Chan School of Public Health followed nearly 32,000 men over 18 years and found something that raised more than a few eyebrows: men who ejaculated 21 or more times per month had approximately a 20% lower risk of prostate cancer compared to men who ejaculated just 4 to 7 times per month. The association held across multiple age groups — men in their 20s, their 40s, and beyond — and remained consistent even after accounting for lifestyle factors like diet, exercise, and PSA screening history.
This wasn’t a one-off finding either. A separate Australian study of over 2,300 men found that those who ejaculated most frequently were 36% less likely to be diagnosed with prostate cancer before the age of 70, compared to men with lower ejaculation frequency. That’s a significant finding from two independent populations on opposite sides of the world.
Why Might This Be?
Researchers have a few working theories, though the science is still evolving. The leading hypothesis is sometimes called the **“prostate stagnation” theory** — the idea that the prostate gland, which produces fluid that forms part of semen, can accumulate potentially harmful substances over time. More frequent ejaculation may help flush out these toxins, reducing the opportunity for cancer-promoting changes to develop.
Another possibility is that men with higher ejaculation frequency tend to have broader healthy lifestyle habits, better physical activity levels, healthier weight, and lower levels of stress, all of which independently support good prostate health.
It’s also worth noting that testosterone plays a role here. Men with higher testosterone levels tend to have stronger sex drives and ejaculate more frequently. And while testosterone is often mischaracterised as a cancer risk, healthy hormonal balance is an important part of overall wellbeing.
What This Doesn’t Mean
It’s important to be clear: #ejaculation frequency is not a cure or guaranteed prevention for prostate cancer. The research is observational, meaning it identifies a relationship but cannot definitively prove cause and effect. Not all studies have found the same results, and importantly, the protective association appears to be strongest for lower-risk prostate cancers, not the more aggressive, advanced forms of the disease.
Other key risk factors; including age, family history, ethnicity, diet, and weight, all remain just as relevant and cannot be outpaced by sexual activity alone.
The Bigger Picture: Men’s Health Matters
What strikes us most about this research isn’t just the specific finding, it’s what it represents: a growing body of evidence that sexual health and general health are deeply connected. For too long, men have been reluctant to talk openly about their bodies, their sexual wellness, and the changes that come with age. Prostate health, testosterone levels, libido, and sexual function are all interconnected, and all worth discussing with a health professional.
At TLC, we work with men at every stage of life to support their physical & emotional health, addressing concerns around sexual wellness and cancer screening awareness.
What You Can Do Right Now
- Get screened. If you’re over 50, or over 40 with a family history of prostate cancer, talk to your doctor about a PSA test.
- Prioritise your sexual health as part of your overall wellness routine — not as an afterthought.
- Look after your lifestyle. Regular exercise, a balanced diet rich in fruits and vegetables, and maintaining a healthy weight all contribute to lower cancer risk.
- Don’t wait. Men are statistically far less likely to seek medical advice early. The earlier issues are identified, the more options you have.

If something in this article felt familiar, it’s likely not random.These patterns tend to show up in the body, in relationships, and in how we experience intimacy.
Good read on a topic that doesn't get talked about enough. It's interesting to see how research continues to explore the connection between lifestyle habits and long term wellbeing. A lot of blokes are becoming more proactive about men's health, and articles like this help clear up some of the myths. The science-backed approach makes the information easier to understand without the usual scare tactics. Definitely worth considering alongside other healthy habits and regular check-ups.
