Between 1897 and 1899, many medical journals (e.g. the Canadian Medical Review, shown here) carried this blurb, about a recent advance by Dr. Enoch Heinrich Kisch.
Never before had anyone realized that the withdrawal method of birth control leads to female dissatisfaction… which leads to occasional heart palpitations… which lead to irregular heartbeat, constipation, vertigo, weeping, and a gloomy view of life. Truly “One of the Evils of Incomplete Coitus”. But don’t worry: “All these symptoms will disappear as by enchantment”, if you just give up the withdrawal method.
The original French report is here at BIU Santé., the French medical history archive. It’s still only four paragraphs — so to see the evidence for Kisch’s “Cardiac Neurosis of Sexual Origin”, you probably have to read one of the noted balneologist‘s books about female physiology.
