Erectile dysfunction is defined as the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. The condition affects millions of men worldwide and becomes more common with age.
The mechanism of erection involves coordinated neurological, vascular, and hormonal processes. Conditions such as diabetes, hypertension, cardiovascular disease, and psychological stress may disrupt this mechanism.
Clinical guidelines from the American Urological Association emphasize a comprehensive diagnostic approach that includes medical history, physical examination, and appropriate laboratory testing.
Treatment options include oral medications, vacuum erection devices, penile injections, and surgical implantation of erotic penile prostheses.
