This is a careful and scientific report of a lifetime spent in studying the physiology and pathology of the male sex function from the libido and mechanical points of view. The author discusses thoroughly the innervation of the male sex organs and shows what nerve centers influence the male sexual function. He shows that erection depends on a cerebral or psychogenic stimulus as well as a local or dermovascular stimulus, the correction being made by the pyramidal tracts to a lumbar center, from which a sacral reflex completes the circuit. A nerve lesion involving any of these structures may produce clinical impotence. Excellent diagrams illustrating the nerve pathways are shown. The act of coitus is discussed under the following nine headings: (1) sexual desire; (2) glandular secretions; (3) erection: reflex, psycho, sensory; (4) intromission; (5) erection: local stimulus; (6) pleasurable, voluptuous sensations; (7) orgasm; (8) ejaculation; (9) depletion. These headings
