Under certain circumstances labor may be much disturbed by pernicious vomiting. The causes comprise actual organic disease of the stomach and functional disturbances from errors in diet. The determining cause of a paroxysm of vomiting is a severe labor pain. The coincidence of labor and vomiting is not unusual in anemic primiparae. Mental emotion is also a cause. As this vomiting may presage the development of eclampsia or some other affection it is best to terminate labor at once. Page 648.

CHAPTER VI
HARMFUL METHODS PRACTICED TO AVOID LARGE FAMILIES

In this chapter it is shown that ignorance of scientific means of preventing conception involves women in harmful practices. The most common is coitus interruptus which results in nervous disorders. Long continued celibacy or unnatural continence leads to sex inversions. When, in spite of these unscientific practices, pregnancy follows, abortion, the greatest disgrace of modern civilization, is the only resort of the harassed mother, unless she will bear unwanted offspring.

COITUS INTERRUPTUS

THE SEXUAL LIFE OF WOMAN IN ITS PHYSIOLOGICAL, BIOLOGICAL AND HYGIENIC ASPECTS. E. Heinrich Kisch, M.D.

The prevailing practice of coitus interruptus leads, in my experience in consequence of the intense hyperaemia of the uterus and the uterine annexa unrelieved by the occurrence of the orgasm, to a condition of stasis in the female reproductive organs, and this ultimately passes on into chronic netritis, (with relaxation of the uterus, retro-flexion, or ante-flexion, catarrhal diseases of the mucous membrane, erosions and follicular laceration of the portio vaginalis) oophoritis and perimetritis. The evil effects of coitus interruptus for a woman are dependent on the fact that the woman fails to obtain complete sexual gratification, and that this has an important influence on her entire organism. If this ungratifying coitus interruptus is frequently repeated in a voluptuous woman disorders of the reproductive organs ensue, and even more frequently nervous disorders in the form of neurasthenia sexualis. P. 403.

Mantegazza believes that organic disease of the spinal cord may actually result from coitus interruptus.

Hirt considers that even when marital intercourse is carefully regulated with respect to frequency, coitus interruptus may lead to neurasthenic manifestations.

Eulenberg also declares that coitus interruptus is already a frequent cause of sexual neurasthenia in women and that its evil influence in this respect is becoming more and more frequently manifest. P. 405.

Valenta declared that coitus interruptus was one of the chief causes of chronic netritis.
