What is the Origin of Sexual Response?

Rooted in human physiology and sexology, the term describes the predictable cascade of autonomic activation that leads to reproductive function. Its clinical relevance is underscored by the dependency of vascular tone and neurochemical balance on sex hormones.

What is the Mechanism of Sexual Response?

Arousal is fundamentally a parasympathetic-driven event involving nitric oxide release and subsequent vasodilation to facilitate blood flow to erectile tissues. Conversely, orgasm is primarily sympathetic. Hormones like testosterone act centrally to modulate desire (libido) by influencing dopaminergic pathways, while also peripherally supporting the integrity of the smooth muscle and endothelial lining necessary for vascular engorgement.

Sexual Response

Meaning

Sexual Response encompasses the complete sequence of physiological and psychological events initiated by sexual stimuli, mediated by a complex interplay between the autonomic nervous system and the endocrine milieu. In hormonal health, the quality and reliability of this response are direct biomarkers of androgenic and general vascular health. It involves distinct phases: desire, arousal, orgasm, and resolution.
