Why Do Men in Their 30s and 40s Get Erectile Dysfunction?

One in four men turning up at a clinic with new erectile difficulty is under 40, and in that group the difficulty is more likely to be severe rather than less. If you are in your thirties or forties and something has changed, erectile dysfunction in younger men is well documented and it carries a specific implication worth understanding before you go looking for a supplement.

How common is erectile dysfunction under 40

Common enough that it is a quarter of the caseload. Capogrosso and colleagues, publishing in the Journal of Sexual Medicine in 2013, analysed 439 consecutive men seeking first medical help for new onset erectile dysfunction at a single academic clinic. One in four was 40 or younger.

The severity finding is the one that surprises people. Nearly half of the men under 40 had severe erectile dysfunction, against 40 per cent of the older men. Younger did not mean milder.

A follow-up from the same group covering 1,179 patients between 2013 and 2021 found the pattern had held, at roughly one in five. Population figures run lower than clinic figures, as you would expect: the British National Surveys of Sexual Attitudes and Lifestyles reported 7.7 per cent of men aged 16 to 34, and a 2017 review in Sexual Medicine Reviews puts prevalence around 8 per cent in men in their twenties and 11 per cent in their thirties.

Both numbers are useful. Clinic data tells you who is presenting; population data tells you how widespread it is. Neither supports the claim, made on some sites, that more than half of men in their thirties are affected.

Why it matters more at this age, not less

Erectile difficulty in a younger man carries a higher relative cardiovascular risk than the same complaint in an older one. That is the finding the clinical literature keeps returning to, and it is the reason a urologist will not simply write a prescription and move on.

Harvard Health reports that in up to 30 per cent of men who see a doctor about erectile difficulty, that difficulty is the first sign of cardiovascular disease. In a man of 35 that is a signal arriving decades early, which is a useful thing rather than a frightening one if it is acted on.

The practical consequence is straightforward. New or worsening erectile difficulty in your thirties or forties warrants a doctor rather than a supplement, and the sooner the better.

Is it stress or is it physical

The pattern tells you more than the severity does. Difficulty that appears with a partner but not alone, or with a new partner and not a settled one, points toward a psychological component. Difficulty that is consistent everywhere and developed gradually points toward a physical cause.

Performance anxiety is genuinely common at this age. A 2020 review in Sexual Medicine Reviews estimates it affects 9 to 25 per cent of men, and identifies cognitive behavioural therapy and mindfulness training as the approaches with evidence behind them.

The two often occur together, which is why guessing at it is a poor substitute for an assessment. The Capogrosso data also found younger men presenting with erectile dysfunction were more likely to smoke and to use illicit drugs than older ones, which is a physical contribution rather than a psychological one.

What is actually driving it

Mostly the same vascular factors that show up decades later, arriving early. The evidence behind each of these is set out in the lifestyle habits guide.

  • Weight and inactivity. In a randomised trial of 110 obese men, two years of diet and exercise coaching returned about a third of them to normal erectile function.
  • Exercise dose. A 2018 systematic review put the effective figure at 40 minutes of moderate to vigorous aerobic exercise, four times a week, for six months.
  • Smoking. The mechanism is disruption of nitric oxide signalling, with a dose relationship, and erectile quality improves after stopping.
  • Sleep. One week of five-hour nights lowered daytime testosterone by 10 to 15 per cent in a controlled laboratory study of ten men.
  • Medication. SSRIs and beta blockers are common causes, and are worth raising with whoever prescribed them rather than working around.

Testosterone does begin a slow decline from around age 30, widely reported at roughly one per cent a year. It is worth checking, though it is rarely the whole story: the largest trial of testosterone replacement improved desire without improving erectile function, which is covered in the article on TRT.

Where Herbal Mojo fits

Herbal Mojo is a six herb supplement taken 30 to 40 minutes before sexual activity, only when needed. It is not a treatment for erectile dysfunction and it does not address a vascular cause.

The evidence behind the six herbs is uneven and the ingredients page states which is which, including where the research is laboratory work rather than trials in men. Two have randomised placebo-controlled trials, two have laboratory work only, and the NIH position is that rigorous studies do not support Saw Palmetto.

For a man in his thirties or forties whose erectile difficulty is new, the honest recommendation is a doctor first. A supplement taken instead of that assessment delays finding something worth finding.

Common questions

Is erectile dysfunction normal in your thirties? It is common, and one in four men presenting with new erectile difficulty at a specialist clinic is under 40. Common is not the same as harmless, which is why it warrants a check rather than a shrug.

Can lifestyle changes reverse it? Often. In one randomised trial about a third of obese men regained normal erectile function through diet and exercise over two years, though those men were young, obese and otherwise healthy, so the result does not transfer to every cause.

Does stress alone cause it? It can, and performance anxiety affects 9 to 25 per cent of men. Stress and a physical cause frequently occur together, which is why a doctor should make the distinction.

Should I try a supplement first? No. New or worsening difficulty at this age is worth investigating before anything else, particularly given the cardiovascular association.
