Erectile

Erectile dysfunction (ED), also known as impotence, is a type of sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual activity.

Causes

ED can have psychological consequences as it can be tied to relationship difficulties and self-image. A physical cause can be identified in about 80% of cases. These include cardiovascular disease, diabetes mellitus, neurological problems such as following prostatectomy, hypogonadism, and drug side effects.

Diagnosis

Psychological impotence is where erection or penetration fails due to thoughts or feelings; this is somewhat less frequent, on the order of about 10% of cases. In psychological impotence, there is a strong response to placebo treatment.

Treatment

Treatment involves addressing the underlying causes, lifestyle modifications, and addressing psychosocial issues. In many cases, a trial of pharmacological therapy with a PDE5 inhibitor, such as sildenafil, can be attempted. In some cases, treatment can involve inserting prostaglandin pellets into the urethra, injecting smooth muscle relaxants and vasodilators into the penis, a penile implant, a penis pump, or vascular reconstructive surgery.

Epidemiology

It is the most common sexual problem in men. The risk of ED increases with the age. It is four times more common in men aged in their 60s than those in their 40s. Men with the cardiovascular disease are more prone to ED.
