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

This early‑nineteenth‑century medical treatise tackles a subject that was once whispered about in doctor’s offices: the health effects of excessive solo sexual activity. Framed as a warning to both physicians and lay readers, the author argues that many ailments—ranging from chronic fatigue to serious respiratory disease—may have roots in a habit that was often dismissed or overlooked. The opening pages lay out the prevailing belief that such practices can erode the body’s strength, citing contemporary physicians, court records, and asylum reports to illustrate the perceived dangers.

The work balances clinical observation with moral concern, presenting case sketches of young men who, unaware of the risk, continue the behavior until illness forces them to seek help. It also surveys opposing opinions of the day, acknowledging voices that deem the feared consequences exaggerated. Readers gain insight into the period’s anxieties about sexuality, the language of early medical caution, and the way social attitudes shaped health discourse.
