Sexual act includes arousal, erection, ejaculation, orgasm, refractory period, and resolution and depend on changes in the autonomic nervous system. Arousal and erection in men results from stimulation of parasympathetic nerves in the male penile organ; reduced activity of sympathetic pathways and release of nitric oxide from the endothelium (1). In women early sexual arousal results from activation of sympathetic nervous system (2).
