Disorders of Menstruation is an 1888 medical monograph authored by Edward W. Jenks and published in Detroit by George S. Davis as part of the Physicians’ Leisure Library, Second Series. This compact volume was intended as a practical reference for physicians managing gynecologic conditions, with a particular focus on menstrual irregularities including amenorrhea, dysmenorrhea, and menorrhagia.

The text reflects late 19th-century gynecologic practice, blending emerging scientific understanding with therapeutic approaches that now appear aggressive or antiquated. Treatments described include pharmacologic interventions using compounds such as iodine, arsenic, strychnine, and opiates, as well as mechanical and surgical techniques including cervical dilation and uterine instrumentation.

The book is notable not only for its clinical content but also for its pharmaceutical advertisements, including products from Parke, Davis & Co. and Fairchild Bros. & Foster. These advertisements provide valuable insight into the commercial side of medicine during this era, when standardized drug manufacturing was still developing and therapeutic claims were often broad and loosely regulated.
