Erectile dysfunction makes it difficult to regularly attain or keep a firm enough erection to have sex. This can interfere with both sexual activity and quality of life, but medications and other treatments are available.
Some people will occasionally experience some difficulty with their penis becoming hard or staying firm. However, erectile dysfunction (ED) is often only a concern if satisfactory sexual performance is consistently impossible.
People may sometimes refer to ED as impotence.
The awareness that ED can be a treatable condition has increased since the discovery that the drug sildenafil, or Viagra, affected penile erections. However, people who have a problem with their sexual performance may be reluctant to talk with their doctor, seeing it as an embarrassing issue.
ED is now well understood and there are various treatments available.
A note about sex and gender
Sex and gender exist on spectrums. This article will use the terms “male,” “female,” or both to refer to sex assigned at birth. Click here to learn more.

ED may affect up to 20 million people in the U.S. The condition’s prevalence is over 50% in those over 50 years old and increases with a person’s age.
Normal erectile function can be affected by problems with a person’s blood flow, nervous system, and hormone levels. A person may also experience ED due to psychological factors, such as anxiety over sexual performance.
Gay men report ED at a higher rate than heterosexual men, according to a 2019 review. However, the exact reasons for this remain unknown, and researchers recommend more study in the field.
Physical causes
Most cases of ED are secondary. This means that erectile function has been normal but becomes problematic. Causes of a new and persistent problem are usually physical.
In rare cases, a person may have primary ED. This is where a person has never achieved an erection. The cause of primary ED may be psychological or the result of a physical condition.
A person should consult a medical professional if they experience persistent erection problems, as an underlying medical condition could be causing the issue. A proper diagnosis can help address any underlying medical issues and help resolve sexual difficulties.
Some of the most common physical causes of ED include:
- heart disease and narrowing of blood vessels
- diabetes
- high blood pressure
- high cholesterol
- obesity and metabolic syndrome
- Parkinson’s disease
- multiple sclerosis
- hormonal disorders, including thyroid conditions and testosterone deficiency
- structural or anatomical disorders of the penis, such as Peyronie disease
- smoking, alcohol use disorder, and substance abuse, including cocaine use
- treatments for prostate disease
- surgical complications
- injuries in the pelvic area or spinal cord
- radiation therapy to the pelvic region
Atherosclerosis is a common cause of blood flow problems. It describes a narrowing or clogging of arteries in the penis, preventing the necessary blood flow to produce an erection.
Numerous prescription medications can also cause ED. A person taking prescription medications should consult their doctor before stopping or changing their medications. Some drugs that may cause ED include:
- drugs to control high blood pressure
- heart medications such as digoxin
- anxiety treatments
- antidepressants, including monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake inhibitors (SSRIs), and tricyclic antidepressants
- opioid painkillers
- some cancer drugs, including chemotherapeutic agents
- anticholinergics
- hormone drugs
Physical causes account for 90% of ED cases, with psychological causes much less common.
Psychological causes
Psychological factors can cause or contribute to ED, with factors ranging from treatable mental health conditions to everyday emotional states that most people experience at some time. These are
Psychological factors can include:
- fear of intimacy
- depression
- general anxiety
A person may also be unable to attain a full erection due to specific sexual performance anxiety, a common psychological factor in people with ED. Sexual performance anxiety affects 9-25% of males, according to a review.
It is also important to note that there can be an overlap between medical and psychosocial causes. For instance, if a person is living with obesity, blood flow changes can affect that person’s ability to maintain an erection, which is a physical cause. However, the person may also have low self-esteem, impacting erectile function, which is a psychosocial cause.
Does riding a bicycle cause ED?
Some research has raised concerns that men who regularly cycle for long hours could have a higher risk of ED, in addition to other men’s health issues such as infertility and prostate cancer.
A 2020 study found a positive correlation between between riding a bike and ED but the evidence to support this correlation was limited. Another study published in 2020 found no correlation between cycling and ED or prostate cancer.
The association between cycling and prostate cancer remains controversial and requires more research.
Prostate disease and ED
Early-stage prostate cancer does not cause ED, but advanced forms of prostate cancer can.
Prostate surgery to remove tumors and radiation therapy to treat prostate cancer can cause ED.
Some medications for prostate cancer may also result in ED. For example, hormone therapies can lower a person’s libido, and by association lead to ED. Research has shown that the medication finasteride may cause sexual dysfunction in men.

There are many treatments for ED, and most people will find a solution that works for them.
Drug treatments
A person with ED can take a group of drugs called PDE-5 (phosphodiesterase-5) inhibitors.
Most of these pills are taken 1-2 hours before sex, the best known being the blue-colored pill sildenafil (Viagra). Other options are:
- vardenafil (Levitra)
- tadalafil (Cialis)
- avanafil (Stendra)
PDE-5 inhibitors are only available by prescription. A doctor will check for heart conditions and ask about other medications a person is taking before prescribing them. People should not take PDE5 inhibitors if they are taking nitrates.
Side-effects associated with PDE-5 inhibitors include:
- flushing
- visual abnormalities
- hearing loss
- indigestion
- headache
Online pharmacies
It is possible to buy treatments over the internet for ED. However, a person should be cautious when doing so.
The United States Food and Drug Administration (FDA) has a
Before ordering, a person should check that their online pharmacy is licensed in the U.S., has a licensed pharmacist, requires a prescription, and offers direct contact with customer relation staff.
People can check whether the pharmacy is licensed using the list of Verified Internet Pharmacy Practice Sites.
The FDA also offers tips for spotting the dangers of an unsafe website, including watching out for the following:
- There is no way to contact the website by phone.
- Prices are dramatically lower than those offered by legal online pharmacies.
- Prescription drugs do not require a prescription for purchase, which is illegal.
- Personal information is not protected.
These illegal sites may send drugs of unknown quality and origin. They may even send the wrong drug or a dangerous product.
Vacuum devices
Vacuum erection devices are a mechanical way of producing or maintaining an erection for people who do not want to use drug treatments or find they are not working.
A person makes their penis rigid by using a vacuum pump sealed around it that draws up blood. An accompanying constriction band then prevents this blood from then leaving the penis.
The lack of spontaneity with vacuum devices means that many people with ED find other treatments preferable. However, other treatments, such as oral medications, can also reduce spontaneity.
Vacuum devices may also be susceptible to mechanical faults that affect their efficacy, such as poor seals.
Surgical treatments
For some individuals, several surgical treatments may be available, including penile implants. In this procedure, a doctor inserts a malleable or inflatable device into the penis. This surgery
In very rare cases, a patient may undergo vascular surgery to treat ED.
Typically a doctor will only recommend surgery only after
