Erectile dysfunction is defined as the persistent inability to achieve or maintain penile erection sufficient for satisfactory sexual performance. The Massachusetts Male Aging Study surveyed 1,709 men aged 40–70 years between 1987 and 1989 and found there was a total prevalence of erectile dysfunction of 52 percent. It was estimated that, in 1995, over 152 million men worldwide experienced ED. For 2025, the prevalence of ED is predicted to be approximately 322 million worldwide. In the past, erectile dysfunction was commonly believed to be caused by psychological problems. It is now known that, for most men, erectile dysfunction is caused by physical problems, usually related to the blood supply of the penis. Many advances have occurred in both diagnosis and treatment of erectile dysfunction. According to the NIH, erectile dysfunction is also a symptom that accompanies many disorders and diseases. Direct risk factors for erectile dysfunction may include the following: Hypogonadism in association with a number of endocrinologic conditions Hypogonadism in association with a number of endocrinologic conditions Low levels of HDL (high-density lipoprotein) Low levels of HDL (high-density lipoprotein) Chronic sleep disorders (obstructive sleep apnea, insomnia) Chronic sleep disorders (obstructive sleep apnea, insomnia) Peyronie's disease (distortion or curvature of the penis) Peyronie's disease (distortion or curvature of the penis) Many chronic diseases, especially renal failure and dialysis Many chronic diseases, especially renal failure and dialysis Smoking, which exacerbates the effects of other risk factors, such as vascular disease or hypertension Smoking, which exacerbates the effects of other risk factors, such as vascular disease or hypertension Age appears to be a strong indirect risk factor in that it is associated with increased likelihood of direct risk factors, some of which are listed above.

Accurate risk factor identification and characterization are essential for prevention or treatment of erectile dysfunction. The following are some of the different types and possible causes of erectile dysfunction: Organic ED involves abnormalities the penile arteries, veins, or both and is the most common cause of ED, especially in older men. When the problem is arterial, it is usually caused by arteriosclerosis, or hardening of the arteries, although trauma to the arteries may be the cause.

The process involves premature and unusually severe hardening of the arteries. Peripheral neuropathy, with involvement of the nerves controlling erections, is commonly seen in people with diabetes. Depression is another cause of ED and is closely related to erectile dysfunction. Because there is a triad relationship between depression, ED and cardiovascular disease, men with depression should be fully evaluated for medical illness as well as psychological factors. There are many neurological (nerve problems) causes of ED. Diabetes, chronic alcoholism, multiple sclerosis, heavy metal poisoning, spinal cord and nerve injuries, and nerve damage from pelvic operations can cause erectile dysfunction. A great variety of prescription drugs, such as blood pressure medications, antianxiety and antidepressant medications, glaucoma eye drops, and cancer chemotherapy agents are just some of the many medications associated with ED. Hormonal abnormalities, such as increased prolactin (a hormone produced by the anterior pituitary gland), steroid abuse by bodybuilders, too much or too little thyroid hormone, and hormones administered for prostate cancer may cause ED. Low testosterone can contribute to ED but is rarely the sole factor responsible for ED.
