title: Biochemical and physiological mechanisms of female genital sexual arousal.
abstract: Limited studies are available concerning physiological and biochemical mechanisms involved in female sexual function and dysfunction. The paucity of physiological and biochemical data pertaining to genital sexual arousal function is attributed, in part, to lack of reliable experimental models and tools for the investigation of female sexual arousal. This review summarizes research efforts from a number of laboratories in which several experimental models have been established. These include the development of in vivo animal models, organ bath studies, and the establishment of cell cultures. The availability of such experimental model systems have facilitated efforts aimed at defining the neurotransmitters responsible for vaginal smooth muscle relaxation, the role of sex steroid hormones and their receptors in modulating genital hemodynamics, smooth muscle contractility, and neurotransmitter receptor expression. A comprehensive and integral understanding of female sexual function requires detailed investigation of the vascular, neurological (central and peripheral), and structural components of this complex physiological process.
