Pro-Erectile Signaling

Meaning

Pro-Erectile Signaling refers to the complex, coordinated cascade of neurovascular and biochemical events required to initiate and maintain penile erection. This physiological process is fundamentally dependent on a healthy balance between parasympathetic nervous system activation and local endothelial function. Optimal signaling requires the efficient release and action of key vasodilatory molecules, primarily nitric oxide (NO), to facilitate smooth muscle relaxation and subsequent corporal tissue engorgement. Clinically, understanding this signaling is essential for diagnosing and treating erectile dysfunction, which is often an early indicator of broader cardiovascular and hormonal compromise.
