In 'A Treatise on the Diseases Produced By Onanism, Masturbation, Self-Pollution, and Other Excesses', L. Deslandes delves into the taboo subject of sexual excess and its detrimental effects on the human body. Written in a scientific and medical tone, the book explores the physical and mental consequences of self-abuse, offering detailed case studies and treatment recommendations. Deslandes' work is a product of the Enlightenment era, in which discussions on morality and bodily health were of great interest to scholars and physicians. The book provides a fascinating insight into the medical beliefs and practices of the time. Deslandes' writing style is precise and informative, making it a valuable resource for understanding historical perspectives on sexual health. This groundbreaking work sheds light on a topic that was rarely discussed openly in the 18th century. L. Deslandes, a respected physician of his time, wrote this treatise as a way to educate the public and medical professionals on the dangers of excessive sexual behaviors. His expertise and experience in the field make this book a reliable source of information on the health consequences of onanism and self-pollution. I highly recommend 'A Treatise on the Diseases Produced By Onanism, Masturbation, Self-Pollution, and Other Excesses' to readers interested in the history of medicine, human sexuality, and the intersection between morality and health.
