Erectile function requires coordinated interaction between neural signaling, vascular responsiveness, and endocrine stability. Nitric oxide-mediated vasodilation plays a central role in facilitating adequate blood flow to penile tissue.
Disruption in neural pathways or vascular integrity may impair erectile performance. Andrology views erectile dysfunction not only as a localized issue but also as a potential early marker of systemic vascular disease. Comprehensive evaluation improves erotic patient outcomes and supports preventive cardiovascular care.
