Erectile Dysfunction

Erectile dysfunction (ED) is characterized by the persistent inability to achieve or maintain an erection adequate for satisfactory sexual performance, affecting approximately 30 million men in the United States and commonly associated with aging. It results from a complex interplay of psychological and organic factors, including vascular, neurological, hormonal, and psychogenic causes. Diagnosis involves a comprehensive evaluation, including medical history, physical examination, and targeted tests such as nocturnal penile tumescence (SRE) testing, to distinguish between psychogenic and organic etiologies and guide appropriate treatment strategies.
