There is a gynecological hygiene with which women should become familiar; it is based on the principle of antiseptic precautions applied to the daily lives of their sex. The object of this is to keep the body and reproductive organs that are exposed to contamination or infection from the outer world in the most refined and scrupulous cleanliness. The vaginal douche or syringe is as important an auxiliary to a refined woman’s toilet case as her tooth brush, because the cleanliness of the genitals is as essential to the preservation of health and comfort, as the possession of a sweet breath and the preservation of the teeth. I am therefore convinced of the hygienic value of familiarizing little children with washing or sponging their external genitals; in a few years this will have become second nature, and they are thus protected for all future time from contracting diseases which have their origin in personal uncleanness. It behooves mothers to avoid all delicacy on this subject, so that their little ones may grow up with the sentiment that to the pure in heart all things are pure. It is false modesty and ignorance which degenerate into vice and excesses; the scientific truth is always pure and holy, because it is based on reason, while abnormal delicacy is only emotional, and is quite likely to shoot into the other extreme, namely, licentiousness. As the world grows wiser, the physiology of the reproductive organs should form a part of its wisdom, and in proportion to this knowledge, will their functions become questions of sense, instead of sentiment and nonsense. The vagina is a membranous canal. It is situated in the cavity of the pelvis, below and behind the bladder, and in front and above the rectum. Its direction is curved from before backwards and a little upwards; its walls are flattened and ordinarily in contact with each other. Its length is about four inches along its anterior wall, and an inch or two longer along its posterior wall. In introducing a nozzle of a syringe it must always be remembered, that the tube is to be introduced directly backward on a horizontal plane with the body in the erect posture; by attempting to introduce it directly upwards, you meet with resistance from the anterior wall of the vagina. In this cavity the secretion is susceptible of decomposition, owing to the accessibility of air laden with germs, which excite fermentation. A day or two after the cessation of the menstrual flow, there still lingers a little blood in the cavity of the vagina; this becoming infected with the germs in the vagina, a decomposition is the result, which is recognized by an offensive smell. The naturally soothing and harmless secretion is now changed into an acrid, irritating fluid, which not only may cause an inflammation of the membrane of the vagina, but also excoriate the skin at the orifice of the canal.
