Inflammation of the external organs of generation, and the fluor albus, resulting from it, is most generally, at least in young girls who have not arrived at puberty, a consequence of onanism. We are convinced, too, that if it were possible to arrive at the facts, we should find that the cause of fluor albus in adults was either recent or former abuses. Whenever we have addressed females on the subject, to ascertain this fact, our conjectures have been verified. This has frequently been the case with servant girls. We have seen several, who were so weakened by fluor albus, and the irritation of the sexual parts, that they have been obliged to quit their situations, being unable to do their duty. We will even say, that the most sincere of these girls have given me such information as to their habits, that we suspect most of this class of onanism. Besides, all authors who have spoken of leucorrhœa and blenorrhœa in females, have mentioned excesses in masturbation and coition as among their most frequent causes. It would be easy to adduce general evidence and special cases in support of this proposition; but this would be useless. For the same reasons, we may state, that diseases of the uterus may very frequently be determined by these excesses, and more particularly by those of coition. Daily observation proves that acute and chronic inflammations of the body and neck of the uterus frequently appear in those females who have indulged in premature enjoyments. We have attended, for more than ten years, a lady affected with chronic metritis, arising from this cause. This lady had began to masturbate before she was eleven years old. She soon became affected with fluor albus, from which she has never been free since. When eighteen years old, she married a vigorous man, and then became addicted to another kind of excess. She now experienced constant pains in the loins, lower part of the belly, and in the groins: she was also troubled with a disagreeable feeling of fatigue in the upper part of the thighs, and experienced as it were a weight, as if something was constantly trying to escape from the sexual parts. The neck of the uterus, instead of retaining its usual situation, proved on examination to be almost at the external orifice of the vagina. Our advice, as to moderation and abstinence, was but imperfectly followed: she was so addicted to onanism, that, although she indulged lawfully, and was the mother of several children, she continued in this habit. It may readily be imagined that she did not derive much benefit from my advice: in fact, the symptoms mentioned above, and many others, still continue. Similar cases are related by other authors, and have fallen under the notice of almost every practitioner.
