ABSTRACT
While some recent valuable insights using imaging techniques have been gained from studies in humans, much of what we know about the anatomy and physiology and the pharmacological control of the CNS pathways that regulate sexual function has relied on animal models. These findings indicate that multiple factors interact at supraspinal levels to influence the excitability of spinal reflexes. Sexual responses are under both voluntary and involuntary control, and significant changes occur during sexual maturity, which depends on type and level of gonadal steroid hormones.
