Bei den meisten Männern ist Erektionsdisfunktion zunächst ein Problem des Blutflusses. Neue, unerklärte Erektionsprobleme sind eines der frühesten Anzeichen dafür, dass die Durchblutung Aufmerksamkeit benötigt, oft Jahre vor einem Herzinfarkt oder Schlaganfall. Sie ist zudem sehr gut behandelbar. Die Veränderungen, die die Blutgefäße reparieren, helfen am meisten.
Regelmäßige Bewegung, eine mediterrane Ernährungsweise, der Abbau von Übergewicht und das Aufhören mit dem Rauchen stärken jeweils für sich genommen die Erektion; Beckenbodentraining bietet eine weitere kostenlose Option. Bei adipösen Männern stellte sich nach zwei Jahren Diät und Bewegung bei etwa einem Drittel eine normale Funktion wieder ein. Die Tabletten wirken bei den meisten Männern gut und gehören nach der Behandlung der Grundlagen. Testosteron hilft nur, wenn die Blutspiegel niedrig sind, und die Stoßwellentherapie ist eine sich entwickelnde klinische Option.

What It Is
Erectile dysfunction is the repeated inability to get or keep an erection firm enough for sex. An occasional off night means nothing. For most men over 40, once the trouble has lasted weeks or months, it is a blood-flow problem before anything else. An erection is a vascular event: arteries relax and fill the spongy tissue of the penis with blood, and muscles at the base trap that blood to hold firmness. The arteries that fill the penis are narrower than the coronary ones. They stiffen and clog earlier, so fatty plaque shows up here first, often well before a heart attack or stroke.
New erection trouble can appear years ahead of those events, and treating it early protects the heart as much as the sex life.
The four common types point to different levers:
- Vascular, the common one. Firmness that faded gradually, often alongside a growing waistline, high blood pressure, high cholesterol, prediabetes or smoking. The arteries fill the penis less well, and this is the type the lifestyle work helps most.
- Psychological, often situational. Reliable morning erections and firmness alone, but trouble with a partner, or a sudden onset tied to stress, anxiety or a new relationship. In Chinese medicine this often reads as Liver Qi constraint. Reducing performance pressure, treating anxiety or low mood, and sometimes a short course of a tablet to break the cycle are what help.
- Hormonal, so test it. Low desire as much as poor erections, with fatigue, low mood or loss of morning erections. This can point to low testosterone, which a blood test through a clinician or a direct-to-consumer panel settles before treatment.
- Drug or nerve related. Onset that followed a new medication (some blood-pressure drugs, antidepressants, finasteride) or that fits nerve or pelvic damage from diabetes, surgery or radiation. The levers here are reviewing medications with the prescriber and tightening glucose control.
What works, and where to start
Five self-directed levers come first: aerobic exercise, a Mediterranean plate, losing excess weight, quitting cigarettes and pelvic-floor training. Each repairs the penile arteries and lowers heart risk at the same time. That is why they lead. The oral tablets help most men and come after these basics.
The Research & Studies
Everything here is based on the research we have collected and checked, sorted into groups and ordered with the strongest evidence first. Click any claim to open the studies behind it.
Sexual Function
Exercise firms erections, most where the cause is vascular
Men who took up regular exercise got firmer, more reliable erections than men who did not.
A pooled analysis of randomized controlled trials found that exercise, mostly aerobic training, improved erectile function scores on the International Index of Erectile Function against control conditions, with the largest gains in men whose erectile dysfunction was linked to vascular causes, physical inactivity, obesity, metabolic syndrome, high blood pressure or heart disease. Measured in: Men with erectile dysfunction enrolled in randomized trials of structured exercise, pooled across studies of predominantly aerobic and combined aerobic-resistance programs.. The trials were small and varied in the exercise prescribed and in how erectile function was measured, so the pooled estimate blends different doses. Exercise was often studied alongside, not instead of, standard care.
Who this may not transfer to:Erectile dysfunction is male-specific, so the finding is not transferable to women. Benefit was clearest in men with a vascular or metabolic cause; men whose erectile dysfunction is purely psychological or drug-induced were less represented.

Sildenafil made about 57% of sex attempts succeed, against 21% on placebo
Sildenafil (Viagra) let most men have successful sex, far more than a dummy pill.
A meta-analysis of randomized trials found that with sildenafil about 57 percent of intercourse attempts succeeded against about 21 percent on placebo, and roughly 83 percent of men reported improved erections against about 45 percent on placebo. Headache, flushing and indigestion were the common side effects. Measured in: Men with erectile dysfunction of mixed causes in placebo-controlled randomized trials of sildenafil.. Trials were mostly industry-sponsored and typically ran a few weeks to a few months. Nitrate heart medicines are the firm exception: taken with a PDE5 inhibitor they can drop blood pressure dangerously, which is why the drug is prescription-only.
Who this may not transfer to:Male-specific. Works regardless of the underlying cause in most men, but needs sexual stimulation to work and does not treat the vascular disease underneath.

Sildenafil, tadalafil and vardenafil work about equally well; tadalafil lasts up to 36 hours
Sildenafil, tadalafil and vardenafil all work about equally well for erections.
A comparative systematic review and meta-analysis found that the oral PDE5 inhibitors improved erectile function, intercourse success and satisfaction versus placebo, and that sildenafil, tadalafil and vardenafil were broadly similar in effectiveness. They differ mainly in timing: tadalafil lasts much longer, up to about 36 hours, which is why it also comes as a low daily dose, while sildenafil and vardenafil act over a shorter window. Headache, flushing, indigestion and nasal congestion were the usual adverse effects. Measured in: Men with erectile dysfunction in randomized trials of oral PDE5 inhibitors and, separately, hormonal treatments.. Head-to-head comparisons were fewer than placebo comparisons, so the similarity between drugs is inferred partly across trials. Choice usually comes down to how long a man wants the effect to last and how each drug suits him.
Who this may not transfer to:Male-specific. Testosterone treatment helped mainly men with confirmed low testosterone, not men with normal levels.

40 minutes of aerobic exercise four times a week improves erections
Doing about 40 minutes of brisk aerobic exercise four times a week improves erections over a few months.
A systematic review of intervention studies concluded that roughly 40 minutes of moderate-to-vigorous aerobic activity four times a week, about 160 minutes weekly, sustained over six months, reduces erectile problems, with the improvement in erectile function scores larger in men who started with more severe dysfunction. Measured in: Men with erectile dysfunction or with cardiovascular disease, obesity, metabolic syndrome or a history of physical inactivity, across the included aerobic-exercise intervention studies.. The included studies differed in design and in how they measured erection quality, and the review pools intervention studies, not a single randomized comparison, so the dose is a practical synthesis, not a precise prescription.
Who this may not transfer to:Male-specific outcome. The dose was drawn from studies of men with a vascular or metabolic contribution; it is the same aerobic prescription that helps the heart.

A Mediterranean diet lowers the risk of developing ED, most before age 60
Men who ate a Mediterranean-style diet were less likely to develop erection problems.
In a large prospective cohort, men whose eating pattern most closely matched a Mediterranean diet or scored highest on the Alternative Healthy Eating Index had a lower risk of developing erectile dysfunction over follow-up, and the association was strongest in men younger than 60. Measured in: Around 21,000 men in the Health Professionals Follow-up Study, a long-running US cohort of male health professionals, followed with repeated diet questionnaires and self-reported erectile function.. What could explain it instead: Healthy-user bias: men who eat a Mediterranean diet also tend to be leaner, more active, less likely to smoke and more engaged with healthcare, and diet cannot be fully separated from that whole pattern. The design shows association, not proof that the food itself caused the lower risk.. Diet and erectile function were self-reported, and the cohort is mostly white health professionals, so the absolute risks may not transfer to other groups.
Who this may not transfer to:Male-specific. The cohort is predominantly white US health professionals, a group that is health-aware and comparatively affluent.

A healthful plant-based diet tracks with fewer erection problems in men in their 60s
Men who ate more healthy plant foods had fewer erection problems, most clearly in their 60s. In men under 60, it was a diet high in unhealthful plant foods that tracked with more erection problems.
In the same cohort, men aged 60 to 69 with the highest healthful plant-based diet index, weighted toward whole grains, fruits, vegetables, nuts and legumes, had an 18 percent lower likelihood of erectile dysfunction (highest quintile HR 0.82, 95% CI 0.73-0.91). In men under 60, it was a diet high in unhealthful plant foods that tracked with more erectile dysfunction (HR 1.27, 95% CI 1.01-1.60), not the healthful pattern. Measured in: Around 21,000 men in the Health Professionals Follow-up Study assessed with a plant-based diet index and self-reported erectile function.. What could explain it instead: Healthy-user bias again: a high healthful plant-based score travels with lower body weight, more exercise and less smoking, so the whole lifestyle, not the plants alone, may carry the benefit. Association, not cause.. As with any diet-index analysis, the healthful and unhealthful plant-food scores capture broad patterns, not single foods, and erectile function was self-reported.
Who this may not transfer to:Male-specific; same health-professional cohort, so the same affluence and health-awareness caveats apply.

Weight loss and activity restored normal erections in about a third of obese men
Overweight men who lost weight and got active over two years saw their erections improve, and about a third recovered normal function.
In 110 obese men with erectile dysfunction and no diabetes or heart disease, a two-year program of a Mediterranean-style diet and increased physical activity raised the mean International Index of Erectile Function score from 13.9 to 17, and 17 of 55 men in the intervention group regained normal erectile function (a score of 22 or more) against 3 of 55 in the control group. Body-mass index, physical activity, blood pressure and markers of inflammation all improved alongside. Measured in: 110 obese men aged 35 to 55 with erectile dysfunction, a body-mass index of 30 or more, and no diabetes, high blood pressure or established heart disease, randomized to a lifestyle program or general information.. A single-center trial of 110 men, and the intervention bundled diet, exercise and regular counseling, so the separate contribution of each cannot be isolated. Men who already had diabetes or heart disease were excluded, so this describes the earlier, more reversible stage.
Who this may not transfer to:Male-specific. Enrolled obese men without diabetes or heart disease, so the recovery rate reflects a relatively early, weight-driven picture, not long-standing vascular disease.

Smoking raises ED risk step by step with amount and years
Smoking makes erection problems more likely, and the more and the longer you smoke, the higher the risk.
A dose-response meta-analysis of observational studies found current smokers had a higher risk of erectile dysfunction than men who never smoked, with the risk rising step by step with the number of cigarettes smoked per day and the number of years of smoking. Former smokers sat between never-smokers and current smokers. Measured in: Men across observational studies comparing erectile dysfunction between current, former and never smokers, with data on smoking quantity and duration.. What could explain it instead: Smokers differ from non-smokers in diet, alcohol, exercise and cardiovascular health, all of which affect erections, so part of the association reflects those other habits, not smoking by itself. That former smokers had lower risk than current smokers, and that the risk tracked dose, both point toward a contribution from smoking itself.. The underlying studies are observational, so smoking travels alongside other habits.
Who this may not transfer to:Male-specific. The dose-response pattern and the lower risk in former smokers support stopping as a lever a man can pull himself.

Pelvic-floor exercises restored normal erections in about four in ten men
Pelvic-floor (Kegel) exercises restored normal erections in about four in ten men who did them.
In a randomized trial of 55 men with erectile dysfunction, three months of pelvic-floor muscle exercises with biofeedback plus lifestyle advice outperformed lifestyle advice alone; after the control group also took up the exercises, about 40 percent of the men regained normal erectile function and a further third improved. Measured in: 55 men aged 20 or older with erectile dysfunction of at least six months, managed in UK primary care.. A small single trial, and the men were taught by a specialist physiotherapist with biofeedback, so results at home from memory alone may be more modest. The pelvic-floor muscles support the mechanism that keeps blood in the erect penis, which is the rationale for training them.
Who this may not transfer to:Male-specific. Free and self-directed once learned; it also helps the post-void dribble that often accompanies erectile dysfunction.

Männer unter PDE5-Hemmern hatten weniger Herzprobleme und niedrigere Mortalität
Männer, die Potenzmittel einnahmen, hatten weniger Herzprobleme und lebten länger, obwohl gesündere Männer möglicherweise eher dazu neigen, sie einzunehmen.
Eine systematische Übersichtsarbeit mit Metaanalyse von Langzeitdaten ergab, dass Männer, die PDE5-Hemmer einnahmen, geringere Raten schwerwiegender kardiovaskulärer Ereignisse und Tod hatten als Männer, die dies nicht taten, also nicht den einst befürchteten Schaden. Dies passt zur Biologie dieser Medikamente, da sie Blutgefäße entspannen, aber die meisten gepoolten Daten sind beobachtend. Measured in: Men prescribed PDE5 inhibitors compared with non-users across long-term cohort and trial data.. What could explain it instead: Prescription bias runs strong here: a man well enough to be prescribed and to use an erection drug, and active enough to want it, is on average healthier than one who is not, so some of the apparent benefit reflects who takes the drug, not the drug itself. What the data does settle is that the older worry about PDE5 inhibitors causing heart attacks is not borne out.. Nitrat-Herzmedikamente bleiben die einzige klare Kontraindikation.
Who this may not transfer to:Male-specific. Reassuring on safety, but the mortality and event benefit should not be read as a reason to take the drug for the heart.

Testosterontherapie verbessert die erektile Funktion um etwa 2.3 IIEF-Punkte bei Männern mit niedrigem Testosteron
Bei Männern mit niedrigem Testosteronspiegel festigte eine Testosteronbehandlung die Erektionen, und der Nutzen war größer, je niedriger der Ausgangswert war.
Eine Metaanalyse von 14 randomisierten placebokontrollierten Studien mit 2,298 Männern fand, dass eine Testosteronbehandlung die Werte der erektilen Funktion auf dem International Index of Erectile Function im Mittel um 2.31 Punkte gegenüber Placebo erhöhte (95-%-KI 1.41 bis 3.22). Der Nutzen richtete sich danach, wie niedrig der Testosteronwert zu Beginn war: Männer mit ausgeprägterem Mangel (Gesamttestosteron unter 8 nmol/l) gewannen etwa 2.95 Punkte (95-%-KI 1.86 bis 4.03), während Männer mit leichterem Mangel (unter 12 nmol/l) etwa 1.47 Punkte gewannen (95-%-KI 0.90 bis 2.03). Die Verbesserung betraf Männer mit bestätigt niedrigem Testosteron, nicht Männer mit normalen Werten. Measured in: Hypogonadal men with confirmed low testosterone and sexual symptoms, pooled from 14 randomized placebo-controlled trials of testosterone treatment.. Der Gewinn ist bescheiden im Vergleich zu dem, was ein PDE5-Hemmer liefert, und er gilt nur dort, wo der Testosteronwert im Blut niedrig ist; die Messung des Testosterons vor der Behandlung ist daher der Schritt, der sie wirksam macht. Die Studien liefen über Wochen bis Monate, und eine Testosteronbehandlung erfordert eigene Kontrollen (Blutbild, Prostata, Fruchtbarkeit), gehört also in ärztliche Hände. Gewichtsabnahme und Bewegung, die sowohl Testosteron als auch Gefäßgesundheit verbessern, kommen zuerst.
Who this may not transfer to:Male-specific. The benefit is confined to men with confirmed low testosterone; it does nothing for erections in men with normal levels, which is why the blood test comes before the prescription.

Koreanischer roter Ginseng verbesserte Erektionswerte in kleinen, schwachen Studien
Koreanischer roter Ginseng zeigte in frühen Studien einen Nutzen für Erektionen, obwohl die Studien klein und uneinheitlich waren.
Eine systematische Übersichtsarbeit randomisierter Studien fand, dass koreanischer roter Ginseng die Erektionsfunktionswerte gegenüber Placebo in den verfügbaren Studien verbesserte, sodass die Richtung des Effekts ermutigend ist. Die Übersichtsarbeit beurteilte die Studien als klein und methodisch schwach, sodass es ein vielversprechendes Signal ist, kein gesichertes Ergebnis. Measured in: Men with erectile dysfunction in randomized, mostly placebo-controlled trials of Korean red ginseng, pooling several hundred participants.. Die Studien waren klein, kurz und von unterschiedlicher Qualität, und Ginseng-Produkte variieren stark in ihrem tatsächlichen Inhalt. In der Chinesischen Medizin ist Ginseng ein wärmendes qi- und Yang-Tonikum, sodass die Tradition ihn für ein erschöpftes, kaltes, müdes Bild vorbehalten würde.

Niedrigintensive Stoßwellentherapie verbessert die erektile Funktion um etwa 4 IIEF-Punkte
Eine Behandlungsreihe mit niedrigintensiver Stoßwellentherapie verbesserte die Erektionsfähigkeit bei Männern mit gefäßbedingten Erektionsproblemen und wirkte am besten bei milderen Fällen.
Eine Metaanalyse von 10 randomisierten scheinkontrollierten Studien mit 873 Männern fand, dass niedrigintensive extrakorporale Stoßwellentherapie die Werte der erektilen Funktion auf dem International Index of Erectile Function im Mittel um 3.97 Punkte gegenüber der Scheinbehandlung erhöhte (95-%-KI 2.09 bis 5.84) und die Wahrscheinlichkeit, eine für die Penetration ausreichend feste Erektion zu erreichen, etwa vervierfachte (Erection-Hardness-Score von 3 oder mehr, Odds Ratio 4.35, 95-%-KI 1.82 bis 10.37). Auch der Blutfluss im Penis, gemessen als maximale systolische Geschwindigkeit, verbesserte sich (Mittelwert +4.12, 95-%-KI 2.30 bis 5.94). Die Behandlung wendet energiearme Schallwellen auf den Penis an, um das Wachstum neuer kleiner Blutgefäße anzuregen, sodass der Nutzen bei Männern am größten ist, deren erektile Dysfunktion gefäßbedingt und leicht bis mäßig ausgeprägt ist. Measured in: Men with erectile dysfunction, mostly of vascular origin and mild to moderate severity, in randomized sham-controlled trials of low-intensity extracorporeal shockwave therapy.. Die Behandlungsprotokolle (Energie, Anzahl der Sitzungen, Gerät) unterschieden sich zwischen den Studien stark, die Nachbeobachtung war kurz, und die gepoolte Analyse klärte nicht, wie lange die Verbesserung anhält; sie gilt daher als aufkommende Option, die über eine qualifizierte Klinik angeboten wird und erst nach den grundlegenden Lebensstilmaßnahmen infrage kommt. Es handelt sich um ein klinisches Verfahren, kein Heimgerät, und viele direkt an Verbraucher vermarktete Geräte sind nicht die untersuchten medizinischen Systeme.

L-Citrullin verbesserte Erektionen bei der Hälfte der Männer mit milder erektiler Dysfunktion in einer kleinen Studie
Ein tägliches L-Citrullin-Supplement verbesserte die Erektion bei der Hälfte der Männer mit milden Problemen in einer kleinen Studie.
In einer kleinen einblinden, nicht randomisierten Studie mit festgelegter Sequenz bei 24 Männern mit milder erektiler Dysfunktion nahm jeder Mann einen Monat Placebo und dann 1.5 Gramm L-Citrullin täglich für einen Monat ein. Der Erektionshärte-Score stieg von einem Niveau, das als nicht hart genug für Penetration beurteilt wurde, auf ein als hart genug beurteiltes Niveau bei 12 von 24 Männern (50 Prozent), gegenüber 2 von 24 (etwa 8 Prozent) unter Placebo. Keine Nebenwirkungen wurden berichtet. Measured in: 24 men, mean age around 56, with mild erectile dysfunction (an erection hardness score of 3).. Eine einzige kleine Studie ausschließlich bei milden Fällen, mit kurzem Behandlungszeitraum. L-Citrullin ist eine Vorstufe, die der Körper auf dem Weg zu Stickstoffmonoxid umwandelt, demselben Weg, auf dem PDE5-Hemmer wirken, was die Rationale bildet, aber der Effekt war weit kleiner als bei einem Medikament und bei schwerwiegenderer erektiler Dysfunktion ungetestet.

Heart And Vascular
ED raises later cardiovascular risk by about 40 percent
Erection problems often appear years before a heart attack or stroke and signal higher heart risk.
A meta-analysis of prospective cohort studies found that men with erectile dysfunction had a higher subsequent risk of cardiovascular events, including a relative increase on the order of 40 percent or more for total cardiovascular events, along with raised risks of heart attack, stroke and death from any cause, compared with men without erectile dysfunction. Measured in: Men in prospective cohort studies with baseline erectile-function status followed for later cardiovascular events and mortality.. What could explain it instead: Erectile dysfunction and heart disease share the same roots, high blood pressure, diabetes, smoking, obesity and unhealthy arteries, so erectile dysfunction is best read as an early readout of vascular health, not an independent cause of heart attacks. The penis has smaller arteries than the heart, which is why they narrow sooner, so erection trouble appears before heart disease.. The size of the association depends on how erectile dysfunction was measured and on the population studied, and it was larger in younger and intermediate-risk men.
Who this may not transfer to:Male-specific. The practical takeaway is that new erectile dysfunction is a reason to check blood pressure, glucose and lipids, not only to reach for a pill.

The lifestyle work that repairs the arteries
Aerobic exercise is the strongest self-directed lever. It restores the artery lining that relaxes to let blood in. The gain is largest in men whose cause is vascular or metabolic, and in those who started more severely affected. A Mediterranean-style diet built on olive oil, oily fish, vegetables, beans and whole grains tracks with a lower risk of ever developing the problem, most strongly in men under 60. Eating mostly whole plant foods lowers the risk too.
Diets built on ultra-processed food, heavy in sugar and refined fat, drive the obesity and prediabetes behind the vascular type. That same metabolic damage reaches the slimmer penile arteries first. Weight loss carries the clearest before-and-after evidence, with the gains in obese men arriving alongside lower blood pressure and less inflammation. Quitting smoking helps too, and the gains build over months. Smoking narrows the penile arteries, so risk climbs with cigarettes a day and years smoked, then falls as the years since quitting add up.
Pelvic-floor training
The muscles at the base of the penis help clamp blood in place, and they can be trained. In a randomized trial, three months of pelvic-floor (Kegel) exercises with biofeedback beat lifestyle advice alone. They cost nothing once learned, carry no side effects, and stack on the exercise and diet work.
PDE5 inhibitor tablets, after the basics
The oral tablets are the most effective medical option. Sildenafil (Viagra), tadalafil (Cialis) and vardenafil work about equally well and differ mainly in timing. Tadalafil lasts up to about 36 hours and also comes as a low daily dose; sildenafil and vardenafil act over a shorter window. All three need sexual stimulation to work, and headache, flushing and nasal congestion are the common side effects. On long-term data, men taking these drugs had fewer major cardiovascular events and lower mortality than men who did not, though much of that data is observational.
Vacuum devices, and testosterone only when it is low
A vacuum erection device is a drug-free mechanical option: a cylinder draws blood into the penis, and a constriction ring at the base holds it there for intercourse. It works independently of the arteries, so it suits men who cannot or prefer not to take tablets, and it is bought once. Testosterone firms erections only when a blood test shows the level is low, and does nothing at normal levels. In men with confirmed deficiency it lifts erectile-function scores by about 2.3 points on a 30-point scale. The effect is modest next to a tablet, and treatment carries monitoring for blood count, prostate and fertility. The weight loss and activity that raise both testosterone and vascular health come first.
At the emerging edge
Low-intensity shockwave therapy applies low-energy sound waves to the penis to prompt new small-vessel growth. It targets the blood supply directly, with the clearest benefit in vascular, mild-to-moderate cases. It sits at the edge because trial protocols varied widely and how long the benefit lasts is unsettled. Many direct-to-consumer devices also differ from the studied medical systems. Two supplements look promising, though the evidence is not yet strong enough to be sure. Korean red ginseng (Panax ginseng) improved erection scores against placebo across small, methodologically weak trials. L-citrulline is a building block the body turns into nitric oxide, the same pathway the tablets use. In one small study of men with mild erectile dysfunction, it firmed erections.
What To Do First
The order matters less than doing a few of these steadily for a few months. The lifestyle work is yours to start today; the tablets and any medication changes are a conversation with whoever prescribes for you.
New erectile dysfunction is a signal to check the arteries, so run a blood-pressure, glucose and cholesterol check first. A clinician can order these, and direct-to-consumer panels run blood sugar, lipids and testosterone on your own schedule if you would rather start there.
Aim for about 40 minutes of moderate-to-vigorous activity four times a week, brisk enough to raise your breathing, and hold it over months. It rebuilds the small vessels an erection depends on, and pays off most in the vascular cases.
Build meals on olive oil, fish, vegetables, legumes and whole grains, and cut sugary drinks and ultra-processed food. It works on the same arteries the exercise does.
The muscles that hold blood in an erection can be trained. Squeeze the one you would use to stop your urine mid-flow, hold a few seconds, then release, and build up daily sets.
Stop smoking; the risk keeps falling for years after you quit. Heavy drinking blunts erections in the moment, so go lighter here too.
If you want a faster result while the lifestyle work takes hold, a PDE5 inhibitor works for most men. It is a shared decision with a prescriber, who will check it against your other medicines.
Go Deeper
- Nitric oxide and the endothelium: the artery-lining signal behind an erection, the exact thing the tablets amplify and the lifestyle work restores.
- Mediterranean diet: olive oil, fish, vegetables and whole grains, built plate by plate.
- Zone 2 cardio and resistance training: the aerobic base and the muscle work that together repair the vascular and metabolic causes.
- High blood pressure: the neighboring vascular problem behind both erectile dysfunction and heart risk, worth treating in its own right.
When to See Someone
Most erectile dysfunction is manageable and much of it improves. It can also be the first sign of a circulation problem, so some of these signs are worth acting on, a few the same day:
- Erectile dysfunction with chest pain or tightness, breathlessness on exertion, or a fluttering or racing heart. Treat this as a possible heart problem and seek urgent care(seek urgent care)
- A painful erection that will not go down after several hours (priapism). This is a medical emergency that can damage the penis and needs same-day care(seek urgent care)
- New erectile dysfunction that came on suddenly, especially with numbness, weakness, difficulty passing urine or loss of bladder or bowel control, which can point to a nerve or spinal cause
- Erectile dysfunction alongside cramping leg pain when walking that eases with rest, a sign of narrowed arteries elsewhere worth assessing
- New erectile dysfunction in a man with diabetes, high blood pressure, high cholesterol or a family history of early heart disease. This group gains the most from the early warning. A blood-pressure, glucose and lipid check is the sensible next step; direct-to-consumer panels can run it
- Low sex drive as much as poor erections, with fatigue and low mood. This can point to low testosterone worth measuring before treating
- Erectile dysfunction that began soon after a new medication. Review it with the prescriber before stopping
- Never take a PDE5 inhibitor tablet with nitrate heart medicines, as the combination can drop blood pressure to a dangerous level
Erectile dysfunction is common and treatable. For many men it is also the first warning that the arteries need checking, and acting on a new, unexplained case early is the sensible move.
Common Questions
Is erectile dysfunction a sign of heart disease?
Often, yes. Men with erectile dysfunction carry roughly a 40 percent higher risk of a later cardiovascular event, and the erection trouble can surface before any chest symptom. New, unexplained cases deserve a metabolic and heart check.
Do the tablets work?
They work for most men. About 57 percent of intercourse attempts succeeded on sildenafil against 21 percent on placebo. The three tablets match each other on success, differing mainly in how long each lasts.
