What is Erectile Dysfunction?
What happens to the penis during an erection

Erectile dysfunction (impotence) is the inability to get and keep an erection firm enough for sex.
Having erection trouble from time to time isn't necessarily a cause for concern. If erectile dysfunction is an ongoing issue, however, it can cause stress, affect your self-confidence and contribute to relationship problems. Problems getting or keeping an erection can also be a sign of an underlying health condition that needs treatment and a risk factor for heart disease.
If you're concerned about erectile dysfunction, talk to your doctor — even if you're embarrassed. Sometimes, treating an underlying condition is enough to reverse erectile dysfunction. In other cases, medications or other direct treatments might be needed.
Erectile dysfunction symptoms might include persistent:
Trouble getting an erection
Trouble keeping an erection
Reduced sexual desire
When to see an Endocrinologist?
An Endocrinologist is a good place to start when you have erectile problems. See your doctor if:
You have concerns about your erections or you're experiencing other sexual problems such as premature or delayed ejaculation
You have diabetes, heart disease or another known health condition that might be linked to erectile dysfunction
You have other symptoms along with erectile dysfunction
Male sexual arousal is a complex process that involves the brain, hormones, emotions, nerves, muscles and blood vessels. Erectile dysfunction can result from a problem with any of these. Likewise, stress and mental health concerns can cause or worsen erectile dysfunction.
Sometimes a combination of physical and psychological issues causes erectile dysfunction. For instance, a minor physical condition that slows your sexual response might cause anxiety about maintaining an erection. The resulting anxiety can lead to or worsen erectile dysfunction.
Physical causes of erectile dysfunction
In many cases, erectile dysfunction is caused by something physical. Common causes include:
Clogged blood vessels (atherosclerosis)
High blood pressure
Metabolic syndrome — a condition involving increased blood pressure, high insulin levels, body fat around the waist and high cholesterol
Certain prescription medications
Peyronie's disease — development of scar tissue inside the penis
Alcoholism and other forms of substance abuse
Treatments for prostate cancer or enlarged prostate
Surgeries or injuries that affect the pelvic area or spinal cord
Psychological causes of erectile dysfunction
The brain plays a key role in triggering the series of physical events that cause an erection, starting with feelings of sexual excitement. A number of things can interfere with sexual feelings and cause or worsen erectile dysfunction. These include:
Depression, anxiety or other mental health conditions
Relationship problems due to stress, poor communication or other concerns
As you get older, erections might take longer to develop and might not be as firm. You might need more direct touch to your penis to get and keep an erection.
Various risk factors can contribute to erectile dysfunction, including:
Medical conditions, particularly diabetes or heart conditions
Tobacco use, which restricts blood flow to veins and arteries, can — over time — cause chronic health conditions that lead to erectile dysfunction
Being overweight, especially if you're obese
Certain medical treatments, such as prostate surgery or radiation treatment for cancer
Injuries, particularly if they damage the nerves or arteries that control erections
Medications, including antidepressants, antihistamines and medications to treat high blood pressure, pain or prostate conditions
Psychological conditions, such as stress, anxiety or depression
Drug and alcohol use, especially if you're a long-term drug user or heavy drinker
Complications resulting from erectile dysfunction can include:
An unsatisfactory sex life
Stress or anxiety
Embarrassment or low self-esteem
The inability to get your partner pregnant
