A Treatise on the Diseases Produced By Onanism, Masturbation, Self-Pollution, and Other Excesses

Deslandes‘s A Treatise on the Diseases Produced By Onanism, Masturbation, Self-Pollution, and Other Excesses is a revealing nineteenth-century medical text devoted to the supposed physical and moral consequences of solitary sexual practice. Written in the grave, classificatory prose of early clinical literature, it combines case histories, physiological speculation, and admonitory rhetoric. The work belongs to a broader European tradition that linked sexuality, nervous disease, hygiene, and moral discipline. L. Deslandes was a French physician shaped by an era in which medicine increasingly sought to regulate private conduct through the language of pathology. His treatise reflects contemporary anxieties about degeneration, self-control, and the fragility of the nervous system. Rather than merely recording symptoms, Deslandes writes as a medical moralist, interpreting bodily disorder through the social and ethical assumptions of his time. This book is recommended not as modern medical guidance, but as an important historical document for readers interested in the history of sexuality, psychiatry, public health, and moral medicine. It offers a striking window onto how science, fear, and social norms once converged around the body.
