What is the Origin of Sexual Arousal?

The term is derived from psychology and physiology, describing the subjective and objective markers of sexual readiness. Its study in hormonal health links directly to the function of the hypothalamic-pituitary-gonadal axis.

What is the Mechanism of Sexual Arousal?

Arousal is initiated by neural stimuli leading to nitric oxide release in the pelvic vasculature, causing vasocongestion and tumescence. Simultaneously, central dopaminergic pathways are activated, often modulated by circulating testosterone levels which influence central drive. Prolactin, while often associated with satiety, plays a role in modulating the sensitivity of these arousal pathways, demonstrating the complex interplay of multiple endocrine signals in achieving and sustaining the response.

Sexual Arousal

Meaning

Sexual Arousal is a complex psycho-physiological state characterized by increased sexual excitement, involving both central nervous system activation and peripheral autonomic responses, particularly parasympathetic outflow. Hormonally, it is heavily influenced by gonadal steroids, particularly testosterone in both sexes, which modulates libido and receptor sensitivity in target tissues. Successful arousal requires an integrated response across neurological, vascular, and endocrine systems.
