Erectile Dysfunction
Also known as: ED · Impotence · Sexual Performance Concerns
Erectile dysfunction is the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual function. It is typically multifactorial — vascular, hormonal, neurogenic, and psychological — and frequently signals earlier cardiovascular or metabolic change.
What you need to know
Erectile dysfunction is rarely isolated. It commonly co-occurs with endothelial dysfunction, low testosterone, insulin resistance, sleep disruption, and visceral adiposity, and it is a recognized early signal of cardiovascular disease in men under 50. A complete evaluation reviews cardiovascular and metabolic biomarkers (lipids, ApoB, A1C, fasting insulin), hormonal context (total/free testosterone, estradiol, SHBG, prolactin), and lifestyle. Treatment pathways include PDE5 inhibitor optimization (tadalafil, sildenafil) and, where indicated, hormone optimization and metabolic intervention.
