Nitric Oxide System

Meaning

The Nitric Oxide System centers on the small, gaseous molecule nitric oxide (NO), a crucial endogenous signaling molecule synthesized by various cells, including endothelial cells, neurons, and immune cells. Functionally, nitric oxide is a potent, short-lived vasodilator that plays an indispensable role in regulating vascular tone, blood pressure, and local blood flow to tissues. Within the hormonal and sexual health space, it is a key mediator of penile erection and clitoral engorgement, acting as a pivotal second messenger. Maintaining the integrity of this system is essential for cardiovascular health and optimal peripheral tissue perfusion.
