Two or Three Cups of Coffee a Day? What Science Says About Coffee and Men’s Health

What Science Says About Coffee and Men’s Health

For many of us in the UK, the day doesn’t truly start until the first cup of coffee is brewed. From a quick espresso in Shoreditch to a flat white in Manchester, coffee is at the heart of modern British culture. But beyond its role as a morning pick-me-up, recent research suggests that coffee may have another surprising benefit for men: supporting sexual health.

According to a study highlighted by the Spanish newspaper ABC (2015), men who consume two to three cups of coffee per day may have a significantly lower risk of erectile dysfunction (ED). Could your daily brew be doing more than just waking you up? Let’s explore what the science says, how caffeine affects the body, and why investing in quality coffee at home may benefit both your tastebuds and your wellbeing.

The Study Behind the Headlines

The research, conducted in the United States using data from the National Health and Nutrition Examination Survey (NHANES), analysed over 3,700 men aged 20 and older. Here’s what they found:

Men consuming 85–170 mg of caffeine per day (about two to three cups of coffee) were 42% less likely to report erectile dysfunction than those who drank little or none.

Men consuming 171–303 mg per day also had a reduced risk (about 39%), though the effect was strongest at moderate levels.

The protective effect was most notable in men who were overweight, obese, or hypertensive—all groups with elevated risk for ED.

Interestingly, the effect was not observed in men with diabetes, a condition strongly linked to ED on its own.

In short, moderate daily coffee intake appeared to be linked with a lower risk of erectile dysfunction, though the researchers were careful to point out this was an association, not proof of causation.

How Could Coffee Help?

The science points to caffeine’s effect on blood flow. When consumed, caffeine acts as a mild stimulant and vasodilator. In the context of sexual health:

Caffeine relaxes smooth muscle tissue within the penis (particularly the corpora cavernosa).

It may also improve blood circulation by relaxing penile arteries.

Better blood flow makes it easier to achieve and maintain an erection.

In other words, the same compound that perks you up in the morning might also keep circulation working where it matters most.

Coffee, Lifestyle, and Men’s Health in the UK

Erectile dysfunction is a common issue among men in the UK, particularly over the age of 40. Causes include stress, obesity, cardiovascular disease, smoking, and sedentary lifestyles. While coffee is no miracle cure, it may play a supportive role in men’s health when combined with positive lifestyle changes.

For British men who already enjoy a daily espresso or cappuccino, the research offers reassurance that your coffee habit could be doing more than just fuelling your commute. The key takeaway? Moderation matters. Two to three cups a day seems optimal. Beyond that, benefits taper off, and excessive caffeine can cause jitters, anxiety, or poor sleep.

Why Quality Matters: From Beans to Machines

Of course, not all coffee is created equal. Instant coffee has its place, but to fully enjoy the health benefits and the flavour you’ll want to brew from fresh, high-quality beans. This is where your choice of coffee machine comes in.

At Lux Espresso, we believe that the journey from bean to cup should be an experience. Whether you prefer the strength of a classic espresso or the smoothness of a latte, the right machine ensures you’re brewing coffee that’s both delicious and potentially beneficial for your wellbeing.

Bean-to-cup machines grind fresh beans for every cup, locking in antioxidants and rich flavour.

Espresso machines deliver the intensity that coffee lovers crave—perfect if you’re sticking to the two-to-three cup “sweet spot.”

Filter coffee machines are great for those who enjoy sipping throughout the morning without overdoing caffeine in one hit.

Investing in quality equipment means you can control your caffeine intake, brew consistently, and enjoy coffee as part of a balanced lifestyle.

Caffeine Isn’t a Substitute for Medical Advice

It’s important to emphasise that while coffee may play a role in reducing ED risk, it isn’t a substitute for medical treatment. Erectile dysfunction can sometimes indicate underlying conditions such as heart disease or diabetes. Men experiencing persistent difficulties should always consult their GP.

That said, enjoying coffee responsibly as part of a healthy lifestyle—balanced diet, regular exercise, limited alcohol, and no smoking—can only be a positive step.

Brewing Tips for Maximum Benefit

If you’re inspired to take advantage of the potential benefits of coffee for men’s health, here are a few practical tips:

Stick to quality beans – Choose freshly roasted coffee from reliable sources. Origin matters: Brazil, Ethiopia, Uganda, and Colombia all produce excellent beans with distinct flavours.

Keep to 2–3 cups a day – That’s roughly 200 mg of caffeine, the level linked to reduced ED risk in studies.

Avoid overloading on sugar – Sweetened lattes and syrups can cancel out the health benefits with excess calories.

Time your coffee – Enjoy it in the morning and early afternoon, but avoid late-night brews that disrupt sleep.

Pair coffee with movement – A brisk walk or gym session plus a morning espresso is a powerful duo for circulation and overall health.

Coffee Culture and Confidence

There’s also the psychological aspect. Rituals like grinding beans, pulling a perfect espresso shot, or frothing milk at home can build confidence and enjoyment—factors that play into sexual wellbeing too. Coffee culture isn’t just about taste; it’s about lifestyle, connection, and vitality.

Conclusion

Coffee is one of life’s simple pleasures. And according to research, two to three cups a day might also reduce the risk of erectile dysfunction in men—particularly those who are overweight or have high blood pressure. While it’s no replacement for medical care, your daily brew could be quietly supporting your wellbeing in more ways than one.

For UK coffee lovers, the message is clear: enjoy your coffee, enjoy it in moderation, and enjoy it with quality equipment that makes every cup worth savouring. At Lux Espresso, we help you brew the best—so you can feel your best.
