Libido and Testosterone Connection

Meaning

The libido and testosterone connection describes the direct, dose-dependent relationship between circulating androgens, primarily testosterone, and the physiological and psychological aspects of sexual desire and function in both men and women. Testosterone acts as a crucial modulator of central nervous system pathways and peripheral vascular health essential for a healthy libido. Clinically, assessing this connection is fundamental to addressing diminished sexual interest or responsiveness, which can often be a subtle indicator of underlying hormonal imbalance.
