Erectile dysfunction (ED)
Erectile dysfunction (ED) is defined as the inability to reliably obtain or maintain an erection satisfactory for intercourse. It is a very common disorder, with one study showing that 30-45% of all men over the age of 57 have ED1. The first step in the process of diagnosing the cause of ED or impotence is taking a comprehensive sexual, medical and psychosocial history.
Specialized diagnostic procedures that may be performed include nocturnal penile tumescence (NPT) testing, vascular procedures such as penile duplex ultrasound or pelvic angiography, and neurologic procedures such as quantitative sensory testing recording vibration, hot, and cold sensation thresholds.
Treatment options include nutraceutical supplementation that target vasodilation, oral medication, intraurethral gels or creams, and penile injections.
