I'm 22 — what is wrong with me?

How common is it, really?

Commoner than almost anyone expects, and the numbers vary widely because studies define it differently.

Community estimates range from about 5% to 35% in men under 40, with higher rates in men who actually seek care.¹² Swiss data put it at 30%, Brazilian at 35%, a Nairobi community sample at 10.4%.³⁴⁵

In urology practice, roughly one in four to one in five men presenting for the first time with new-onset erectile dysfunction is younger than forty.⁶⁷

And there is an oddity in the most recent US national survey worth knowing about: 17.9% of men aged 18–24 met the criteria, against 13.3% at 25–34 and 12.7% at 35–44 — a peak in the youngest group, even though prevalence rises again steeply with age across the rest of the lifespan.⁸ Commentators have argued this may reflect distress, inexperience or situational difficulty being captured by a screening tool built for older men,⁹ which is a fair caution rather than a dismissal.

The mental-health signal is real — and it runs both ways

This is the most consistent finding in the young-men literature.

Anxiety, depression and related distress repeatedly track with worse erectile function.¹¹⁰¹¹ In a US cohort of men aged 18 to 31, antidepressant use was associated with more than threefold higher odds of moderate-to-severe ED, and anxiety was independently associated too.¹⁰

But the relationship is not one-directional. Young men with ED had higher rates of depression and anxiety before diagnosis, and continued to develop these conditions more often after diagnosis than matched controls.¹² Longitudinal Swiss data found that poor mental health, depression, and taking medication without a prescription predicted both persistence of ED and new cases over about fifteen months.¹³

So it is not simply that anxious men get ED, or that ED makes men anxious. Both are happening, which is why treating only one half tends to disappoint.

Why "it's just psychological" is often wrong

Because at least 15 to 20% of young men with erectile dysfunction have an organic cause, and clinic series report considerably more where men are investigated thoroughly.¹⁴¹⁵ Contemporary reviews describe ED in this age group as multidimensional, with mixed causes far commoner than a tidy psychogenic-versus-organic split.¹⁶¹⁷

The vascular findings are the ones that should end the assumption. In a cohort of men under 40 with refractory ED, penile duplex ultrasound found 93.7% had some degree of arterial insufficiency, and 40% also had evidence of venous leak.¹⁸ In a larger retrospective study of younger ED patients, 21.5% had vasculogenic dysfunction, with diabetes the strongest independent predictor.¹⁹

Mendelian randomisation — which uses genetic variation to get closer to causation — supports likely causal roles for obesity, type 2 diabetes, smoking, hypertension, insomnia, snoring, coronary heart disease and major depressive disorder in ED risk.²⁰

None of that is a reason to panic at twenty-two. It is a reason to be assessed rather than reassured.

What about testosterone?

Usually not the answer, and the evidence pulls in two directions depending on where you look.

Low testosterone is described as an uncommon cause overall,²¹ and a population-based study of young Finnish men found no significant association between free testosterone and ED symptoms.²² Clinic-based studies, by contrast, report testosterone deficiency more often in young men presenting with ED than in comparison groups²¹ — which is what you would expect, since men who present are not a random sample.

One finding is worth flagging: elevated oestradiol has been independently linked with organic ED in young men whose testosterone was normal.²³ It is not part of most routine panels.

What men are already doing about it

Quietly, and often badly.

In one large young US cohort only 2% reported using ED medication or supplements — but nearly 30% of those users had misused prescription medication.¹⁰ In a separate survey of men aged 18 to 40, 39% reported prior ED medication use, privacy was a major factor in how they obtained it, and only 28% could correctly identify key points about how to take it properly, despite most saying they had been counselled.²⁴

A tablet obtained privately, taken incorrectly, and abandoned as a failure is one of the commonest histories I take.

What actually works

PDE5 inhibitors work well in young men — clinic studies report efficacy of roughly 73 to 85% — but they work best when matched to the underlying cause rather than issued blind.²⁵¹

For young men in whom no organic cause is found, a combined approach of daily low-dose PDE5 inhibitor plus psychosexual therapy improved erectile function and satisfaction over at least six months.²⁶

And the assessment is not elaborate. Reviews consistently call for a focused sexual and medical history, a physical examination, and basic bloods before anyone concludes the problem is psychological.^1141517 More specialised testing — morning testosterone, vascular studies — earns its place when symptoms are persistent, severe, refractory to first-line treatment, or when the history points somewhere specific.²⁷¹⁴¹⁸

How strong is the evidence?

The prevalence figures are wide-ranging because the definitions are, and should be read as a range rather than a number.²⁸ The vascular findings come from selected clinic populations — men with refractory ED are not representative of all young men, and 93.7% should be read as "in men who did not respond to treatment", not "in young men generally".¹⁸ The Mendelian randomisation work is the strongest causal evidence here.²⁰

Bottom line

Erectile dysfunction at twenty-two is neither rare nor automatically psychological. It is usually a mixture — mood, relationship context, lifestyle and, in a meaningful minority, something vascular, metabolic or hormonal that is worth finding early.

Young men are the group most likely to be told this is stress and sent away, and the group where a reversible cause is most likely to be found. I take it seriously at twenty-two for the same reason I take it seriously at sixty-two: something has changed, and it is usually possible to find out what.
