Some of the known neuroanatomy and neurophysiology relevant to male sexual responses is briefly reviewed. A theory is presented which attempts to explain many of their properties. In particular, increases in chemical concentrations of neuroexcitatory chemicals due to stimulation of genital receptors leads by wave-like spread to ejaculation with orgasm as a concomitant. Threshold phenomena and refractoriness are natural consequences of the theory.
