Erectile Function

Meaning

Erectile Function is the complex, integrated neurovascular and hormonal process that results in the engorgement and rigidity of the penile corpus cavernosum, which is necessary for successful sexual intercourse. This function represents a precise integration of central nervous system signals, peripheral nerve impulses, and localized vascular dynamics, all modulated by circulating sex hormones, primarily testosterone. Optimal erectile function is a critical clinical biomarker of overall vascular health, endothelial integrity, and systemic endocrine balance in men.
