title: Biology of female sexual function.
abstract: Although the psychosocial and relationship aspects of female sexuality have been extensively investigated, studies concerning the anatomy, physiology and pathophysiology of female sexual function and dysfunction are limited. The paucity of biologic data may be attributed to a lack of reliable experimental models and tools for investigating female sexual function and to limited funding, which is critical for developing experimental approaches. Research efforts by several investigators in different laboratories have been establishing experimental models needed for investigating the physiologic mechanisms involved in the genital arousal response of sexual function. These experimental models have permitted assessment of genital hemodynamics, vaginal lubrication, regulation of genital smooth muscle contractility and signaling pathways, providing preliminary information about the role of neurotransmitters and sex steroid hormones in sexual function. Further research is needed to define the neurotransmitters responsible for vaginal smooth muscle relaxation and the role of sex steroid hormones and their receptors in modulating genital hemodynamics, smooth muscle contractility, and neurotransmitter receptor expression. Finally, a global and integral understanding of the biologic aspects of female sexual function requires investigation of the vascular, neurologic (central and peripheral), and structural components of this extremely complex physiologic process.
