What is the Origin of Sexual Vitality Signaling?

This terminology specifically isolates the hormonal and neurological components required for healthy sexual expression, distinguishing it from general energy or mood. It acknowledges the deep integration between reproductive endocrinology and neurological drive.

What is the Mechanism of Sexual Vitality Signaling?

Effective signaling relies heavily on appropriate pulsatile output from the $text{HPG}$ axis, leading to adequate levels of sex steroids like testosterone. Peripheral action involves robust androgen receptor sensitivity in target tissues. Furthermore, optimal vascular health, often supported by nitric oxide signaling, is required for the necessary hemodynamic changes associated with arousal.
