Erectile Dysfunction: What You (or Your Partner) Need to Know

Erectile dysfunction (ED) can be frustrating and difficult to discuss, but it is common and treatable. Understanding its causes—from cardiac issues to stress—can help men find effective solutions and enhance their overall health.

“ED is a solvable problem, and an open conversation with your doctor is an important first step,” says Joseph P. Alukal, MD, a professor of urology and director of the Multidisciplinary Men’s Health Program at Columbia.

Because ED has both physical and psychosocial components, Dr. Alukal joins Walter O. Bockting, PhD, a professor of medical psychology and director of the Department of Psychiatry’s Program in Health and Society, to explain the varied causes and potential therapies for this treatable condition.

What is erectile dysfunction?

Erectile dysfunction is the persistent difficulty getting or maintaining an erection firm enough for sexual activity.

“Symptoms may include trouble achieving an erection, losing an erection before sexual activity is complete, or experiencing a reduced interest in sex,” says Dr. Alukal.

Occasional erection difficulties are common and do not necessarily indicate a medical problem. But difficulties that persist, worsen, or interfere with sexual satisfaction deserve attention.

Erectile difficulties can also occur simply as men age. Erections may become less firm, and men may need more direct stimulation to achieve and maintain them.

What causes ED?

“An erection depends on a complex interaction among the brain, hormones, nerves, muscles, and blood vessels,” notes Dr. Alukal. Problems affecting any of these systems can contribute to ED.

Physical causes include cardiovascular disease, high blood pressure, elevated cholesterol, diabetes, obesity, hormonal changes, certain neurological conditions, and the effects of prostate treatments or pelvic injuries. Some medications, including certain blood pressure drugs and antidepressants, can also contribute.

Psychological factors, such as stress, anxiety, depression, performance anxiety, or relationship difficulties, can also play a role in causing or worsening an existing physical problem. “A man who experiences difficulty once may begin worrying about whether it will happen again, creating a cycle in which anxiety makes an erection more difficult,” says Dr. Bockting.

The pattern of ED occurrence matters, too. “Difficulties that occur only in particular situations suggest a psychological or relationship component, while persistent problems across situations may warrant closer evaluation for physical causes,” adds Dr. Bockting.

Could ED signal another health problem?

“There's a fascinating overlap between ED and heart health,” says Dr. Alukal. New or progressively worsening ED can sometimes be an early warning sign of cardiovascular disease because the blood vessels supplying the penis may be affected by the same processes that affect the heart.

ED has been associated with an increased risk of heart attack and stroke, making it important to evaluate new symptoms rather than simply seek a prescription.

Could lifestyle changes improve sexual function?

Although not every case of ED can be prevented, Drs. Alukal and Bockting want men to know that healthy habits can reduce risk and support sexual function. Their recommendations include:

• Protect cardiovascular health. Exercise regularly, maintain a healthy weight, and work with your healthcare professional to manage blood pressure, cholesterol, and diabetes.
• Avoid smoking. Tobacco damages blood vessels and reduces circulation, which can impair erections.
• Limit your alcohol intake and recreational drug use. Heavy drinking and smoking marijuana can interfere with sexual function and desire.
• Prioritize sleep and stress management. Address persistent stress, anxiety, or depression, and seek help when needed.
• Communicate with your partner. Honest conversations can ease pressure and help couples approach intimacy without making intercourse or maintaining an erection the sole measure of success.
• Review medications with your doctor. If ED begins after starting a medication, ask whether alternative prescriptions may be appropriate. Never stop a prescribed medication without medical guidance.

When should you see a doctor about ED?

If erection difficulties are persistent, worsening, or bothersome, making an appointment with your primary care physician or internist is a good starting point. A urologist can provide specialized evaluation and treatment, particularly when initial approaches are unsuccessful or more advanced therapies are needed.

What ED treatments are available?

Treatment depends on the cause and severity of ED. Options include prescription oral medications such as sildenafil (Viagra) and tadalafil (Cialis), which enhance the body's response to sexual stimulation. They are not suitable for everyone, and a clinician should check for potentially dangerous medication interactions, including with nitrate drugs used for certain heart conditions, says Dr. Alukal.

Other options include medication injections into the penis, urethral medications, vacuum erection devices, and, when appropriate, surgically implanted penile devices. Counseling or sex therapy can help address performance anxiety, stress, and relationship concerns; involving a partner may also be useful.

Addressing the psychosocial and relational components, Dr. Bockting notes that “research shows a combined approach—counseling along with medication—is best, especially in the long run.”

And Alukal stresses, “A discussion with your doctor is an important start toward identifying the cause or causes of your ED and improving your health.”
