Sudden or temporary ED: common causes and how long it lasts

In short: erection trouble that shows up suddenly, or comes and goes, is common, and it does not come with a fixed expiry date. It tends to last as long as whatever is behind it. A stressful stretch or a heavy night of drinking can get in the way for a while and then ease. A new medicine, an injury or a health condition can keep it going until that cause is looked at. This guide covers what can make ED start suddenly, what the research says about how often it improves on its own, and which situations mean you should get checked soon rather than wait.

What can make ED start suddenly?

Several of the recognized causes of ED are tied to a specific event or change, so they can line up with trouble that seems to start suddenly: stress or anxiety, drinking too much, recreational drugs, a new or changed medicine, and an injury or surgery that affects the nerves. To get an erection, the brain, nerves, hormones and blood vessels all have to work together, and MedlinePlus explains that anything that gets in the way of those can lead to erection problems (MedlinePlus, Erection problems).

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) groups the causes of ED into four families: diseases and conditions, medicines, mental health or emotional issues, and lifestyle behaviors (NIDDK, ED symptoms and causes). The table lists the ones tied to a specific event or change, but it is a guide to what to mention to a clinician, not a way to diagnose yourself.

Long-term conditions, such as diabetes, high blood pressure, clogged arteries and low testosterone, are on the same lists. A change can feel sudden even when the cause has been developing for a while, which is one reason a clinician will want the whole story rather than just the last few weeks.

How long does temporary ED last?

Temporary ED has no set length, because it depends on the cause. MedlinePlus says almost all adult men have trouble getting or keeping an erection at one time or another, and that the problem often goes away with little or no treatment (MedlinePlus, Erection problems). Trouble tied to a passing cause, such as a stressful week, tends to ease when that cause does. Trouble tied to a medicine or a health condition usually needs that cause addressed.

Longer-term studies show that ED is not always permanent and can improve over time. In the Massachusetts Male Aging Study, which followed men aged 40 to 70 over several years, 35% of the men with ED at the start showed remission at follow-up, while about a third of those with minimal or moderate ED got worse (Travison et al., Journal of Urology, 2007). A later analysis of two cohorts found that 21% and 25% of men with some ED improved over follow-up periods of about 7 and 3 years, and that worsening became more common with age (Travison et al., Journal of Sexual Medicine, 2011).

The studies tracked groups of men over years, not individual episodes over days. They support the idea that ED is not always permanent. They cannot tell you how long your own trouble will last, and they are not a reason to wait if it keeps happening.

Can stress or anxiety cause sudden ED?

Yes. NIDDK says anxiety, depression, stress, feeling isolated or lonely, and low self-esteem can either cause ED or make it worse (NIDDK, ED symptoms and causes). MedlinePlus adds feelings of doubt and failure, fear, anger, poor communication with a partner, and expecting too much from sex, which it says can turn sex into a task instead of a pleasure (MedlinePlus, Erection problems).

This is how a single off night can turn into a run of them. Worry about the last time can get in the way of the next time. Our guide on ED versus performance anxiety explains that loop and how to tell it apart from a physical cause. NIDDK says a clinician may suggest counseling when mental health or emotional issues are affecting ED, and that counselors can help lower anxiety and stress about sex (NIDDK, ED treatment).

Can alcohol cause temporary ED?

Yes, alcohol can be part of it. NIDDK lists drinking too much alcohol among the lifestyle behaviors that may contribute to ED (NIDDK, ED symptoms and causes), and MedlinePlus includes alcohol, along with nicotine, cocaine, marijuana, amphetamines and opioids, on its list of drugs that may cause erection problems (MedlinePlus, Drugs that may cause erection problems).

There is a second point worth knowing. NIDDK says illicit drugs and too much alcohol can sometimes mask other mental health, emotional or physical factors that cause ED, and it lists limiting or stopping alcohol among the lifestyle changes a clinician may suggest (NIDDK, ED treatment). So if cutting back does not settle things, that is useful information to take to a visit. Our guide to alcohol, drugs and other lifestyle factors covers this in more depth.

Can a new medicine cause sudden ED?

Yes. NIDDK says ED can be a side effect of many common prescription and over-the-counter medicines, including antidepressants, antihistamines, blood pressure medicines and water pills, some pain relievers, sedatives, ulcer medicines, and chemotherapy and hormone medicines (NIDDK, ED symptoms and causes). MedlinePlus keeps a longer list and notes that a medicine that causes erection problems in one man may not affect another (MedlinePlus, Drugs that may cause erection problems).

The medicine’s own label is the best place to check. Two examples from FDA labels on DailyMed show how different the picture can be:

• Sertraline (Zoloft), an antidepressant. The label warns that in men, SSRI use may result in ejaculatory delay or failure, decreased libido and erectile dysfunction. It also tells prescribers that the timing of symptom onset matters, because sexual symptoms may have other causes, including the condition being treated (ZOLOFT prescribing information, DailyMed).
• Finasteride (Proscar), for an enlarged prostate. In a 4-year placebo-controlled trial, impotence judged drug related was reported by 8.1% of men on finasteride and 3.7% on placebo in year 1, and in years 2 to 4 there was no significant difference between the groups. The label also lists rare postmarketing reports of sexual problems, including erectile dysfunction, that continued after the medicine was stopped (PROSCAR prescribing information, DailyMed).

Expectations can play a part too. In a small study of 96 men starting the beta blocker atenolol, none of whom had ED at the start, ED was reported after 3 months by 3.1% of men who were not told which drug they were taking, 15.6% of men told the drug’s name, and 31.2% of men told the drug’s name and its possible effect on erections (Silvestri et al., European Heart Journal, 2003). It was one small study of one drug, but it shows why timing and context matter.

Do not stop a prescribed medicine on your own. NIDDK and MedlinePlus both say to talk with your health care professional first, who may suggest a different dose or another medicine (NIDDK, ED treatment; MedlinePlus, Erection problems). Our guide to medicines that can affect erections goes through the main groups.

Does sudden ED mean the cause is psychological?

Not on its own. A review of how young men with ED are evaluated lists sudden onset, good erections at other times, major life events and past psychological problems as clues that suggest a psychological cause, and gradual onset as more suggestive of a physical one (Papagiannopoulos et al., Asian Journal of Andrology, 2015). MedlinePlus says that if you have erections in the morning or at night while you sleep, the cause is likely not physical, but it also says most erection problems have a physical cause (MedlinePlus, Erection problems).

Clues are not a diagnosis. In a study of 2,009 men seeking care for ED for the first time, about one in nine met criteria suggestive of a mainly psychological cause, and their ED could be as severe as in men with a physical cause (Pozzi et al., Andrology, 2022). Many men have a mix of both. A clinician sorts this out with a medical, sexual and psychosocial history, an exam and selective lab tests, which is what the American Urological Association recommends for every man with symptoms of ED (AUA Erectile Dysfunction Guideline).

When is sudden ED a reason to see a doctor soon?

See a clinician soon if the trouble began after an injury or prostate surgery, if it comes with other symptoms such as low back pain, abdominal pain or a change in urination, or if it does not go away with lifestyle changes. Those are the situations MedlinePlus lists for contacting a provider (MedlinePlus, Erection problems). It also suggests a visit if you have trouble more than 25% of the time.

Even when the change seems to have an obvious explanation, it is worth taking seriously. The AUA guideline says men should be counseled that ED is a risk marker for underlying cardiovascular disease and other health conditions that may warrant evaluation and treatment (AUA Erectile Dysfunction Guideline). A risk marker is a reason to look, not proof that something is wrong. Our guide on when to see a doctor about ED covers the red flags in more detail, and what to expect when ED is diagnosed walks through the visit.

The bottom line

Sudden or temporary ED is common, and it does not have a fixed timeline. It tends to last as long as its cause. Stress or drinking can be behind a rough patch that eases on its own, while a new medicine, an injury or a health condition may keep it going until someone looks at it. Long-term studies show that ED improves over time in a meaningful share of men, but they cannot predict your own course. If it keeps happening, or began after an injury, surgery or a new prescription, a calm conversation with a clinician is the next step.
