_Meinert_, in an interesting manner, brings the harmfulness of wearing a corset during the years of development into etiological relations with chlorosis. In the transitional period between childhood and the age of puberty the wearing of the corset usually begins. Now _Meinert_ discovered that in chlorosis, as a result of wearing a corset, a vertical or subvertical position of the stomach ensues as a partial manifestation of enteroptosis, leading to tension on the abdominal plexus of the sympathetic, which in turn results in changes in the blood, and other nervous symptoms. According to this view, chlorosis is a peculiar general neurosis dependent upon an artificially induced gastroptosis; this form of enteroptosis being due, not to relaxation of the suspensory ligaments of the abdominal viscera, but to pressure exercised by adjacent organs in consequence of a change in the form of the thorax, which has been permanently constricted by tight-lacing (_fixierter Schnurthorax_). Of importance is the fact that in girls suffering from chlorosis a condition of hypoplasia of the genital organs is not infrequently met with. It would seem, not only that imperfect development of the female genital organs may be a cause of chlorotic changes in the blood, as appears possible in view of the relations between the ovaries and the hæmatopoietic organs through the intermediation of the sympathetic system; but also that genuine chlorosis and the anomalies of the genital organs met with in this disease, may perhaps be common manifestations of some more general disturbance. According to _Virchow_, two distinct forms of chlorosis are to be recognized, one form in which no great abnormalities of the reproductive apparatus exist, and another form in which imperfections in the development of the central portion of the vascular system are associated with similar imperfections in the reproductive apparatus. In many cases of chlorosis, he found the ovaries small and imperfectly developed, in an infantile condition; in other cases, however, they were three times the normal size; the development of the uterus in such cases usually corresponds with that of the reproductive glands. With regard to the etiological connection between chlorosis and developmental disturbances, _Virchow_ inclines to the view, that in chlorosis a predisposition, either congenital or else acquired in early youth, must be assumed to exist, but that this does not manifest itself by the production of actual disorder until the arrival of puberty; and he considers it likely that primary deficiencies of the blood and the vascular apparatus hinder the development of the reproductive apparatus.
