Operative measures for the production of artificial sterility have been practised from very ancient times, and by civilized and savage peoples alike. According to Strabo, the ancient Egyptians and Lydians were acquainted with the art of removing the ovaries from girls and women. The kings of Lydia, Andromytes and Gyges, had the women of their harems castrated, ut iis semper ætate et forma florentibus uteretur. Von Micklucho-Mackay reports that in some parts of Australia the indigens remove the ovaries of certain girls, in order to provide their young men with hetairæ who cannot possibly become pregnant. M. Gillirray saw at Cape York a native deaf and dumb woman whose ovaries had been removed, to prevent her procreating deaf and dumb infants.
We cannot refrain from reference to the astounding proposal of C. A. Weinhold, contained in his work upon the over-population of Central Europe and its consequences to the countries concerned and to civilization in general. He advises, “as a general and urgently required measure, the widespread practice of a sort of infibulation, which is to be undertaken at the age of fourteen and preserved until marriage, and is to be performed in the case of all those individuals who can be proved not to possess sufficient property for the upbringing of an infant, if they should become pregnant as a result of extra-conjugal intercourse. And in those who never attained a financial position in which they might be able to bring up a family, the infibulated condition should be allowed to persist throughout life!”
This proposal is, in fact, no novelty, inasmuch as the bringing about of an artificial adhesion of the labia with a view to the prevention of conception—the operation of infibulation—is practised by many savage peoples. According to the detailed account given by Ploss-Bartels, this operation, in which the inner surfaces of the labia majora are freshened, stitched together, and allowed to adhere, is practised by the Bedschas, the Gallas, the Somalis, the inhabitants of Harrar, at Massaua, etc. The purpose of this practice is to preserve the chastity of the girls until marriage, when the reverse operative procedure is undertaken. If the husband goes away on a journey, in many cases the operation of infibulation is once more performed upon his wives. Slave-dealers also make use of this operation so as to prevent their slaves from becoming pregnant. It is reported, however, that the operation does not invariably produce the desired effect. Hartmann informs us that in Nubia, in Senaar, and in part of Kordofan, the præputium clitoridis or the entire clitoris is cut away, and the margins of the nymphæ are then freshened and stitched together, so that the only aperture left is one sufficiently large for the outflow of the urine.
Brehm states that the operation is performed by old women, who make the necessary incisions with razors; shortly before marriage, the bridegroom sends the girl’s relatives a model of his penis, carved in wood, according to the size of which an aperture is made between the adherent nymphæ; when the woman becomes pregnant, the incision is still further enlarged. In the kingdom of Darfur, the labia majora as well as the nymphæ are freshened and stitched together. In the Berber country, Werne became acquainted with a young widow whose husband had had her submitted to the operation of infibulation no less than seven times. Another somewhat less brutal method of performing infibulation is described by Ploss, as being practised by many Eastern races; a ring is fastened through the labia in such a way as to guard the introitus vaginæ In Europe, during the Middle Ages, such and similar apparatus (“girdles of chastity”) are said to have been employed for the protection of the honour of an absent husband.
Of gynecologists who have advised operative measures for the prevention of pregnancy, in women in whom that condition involved serious dangers, the first, as far as I know, was Blundell. As a result of experiments made on rabbits, he suggested division of the Fallopian tubes as the best way of attaining this end. Later, Froriep and Kocks also endeavoured to induce artificial sterility in women by occlusion of the Fallopian tubes. Froriep’s idea was to bring about obliteration of the lumen of the tubes by means of cauterization with nitrate of silver; Kocks constructed for the same purpose a galvano-caustic uterine sound. But, in the first place, both the methods advocated are too uncertain to be relied upon; and, in the second place, their application is neither easy, nor devoid of serious risk.
Much more effective, however, is the method recommended by Kehrer for the sterilization of women, namely, division of the Fallopian tubes by the vaginal route. Kehrer considers that the physician is justified in preventing the occurrence of pregnancy in a number of morbid conditions—incurable nervous, cardiac, pulmonary, gastric, and renal disorders; various constitutional affections; and, finally, in cases of pelvic deformity of such a degree that the delivery of a living child is impossible except by means of Cæsarean section, but the patient does not wish to be exposed to the risks of this operation. He believes, moreover, that all the methods commonly recommended for the prevention of pregnancy are untrustworthy. So powerful, however, is the sexual impulse, that, as experience shows, the mere prohibition of sexual intercourse, however earnestly made, invariably proves ineffectual. For coitus interruptus to be effective, the interruption must occur at the right moment; and this does not always take place. Cold water douches after coitus are unhygienic; douches of warm water, medicated with sublimate, alcohol, and other drugs lethal to the spermatozoa, are indeed rationally conceived, but often fail of their effect, either because they are deferred until too late, or else because they fail to irrigate all parts of the vagina. Plugs of cotton wool, sponges, etc., are not always introduced in such a way as effectually to occlude the vaginal passage. A suitable and properly introduced occlusive pessary is, indeed, a relatively trustworthy preventive apparatus, but if worn continuously it is apt to become very foul. A thorough douching of the genital passage with an antiseptic solution, performed by the skilled hand, immediately after coitus, would doubtless destroy the spermatozoa with the like certainty with which the same procedure destroys micro-organisms when performed prior to a gynecological operation—but when carried out by the layman, the value of the method is more than doubtful. The operation, for a time actually fashionable, of extirpation of the uterine annexa, certainly gives rise to sterility, but entails the serious disadvantage that the consequent premature menopause is attended by the same disturbances as the natural change of life. On the other hand, section and ligature of the Fallopian tubes is considered by Kehrer to induce sterility without in any other way disturbing the functions of the female reproductive organs. By means of anterior colpotomy we obtain a suitable route for the ligature and section of both tubes at the isthmi. When carried out with the proper antiseptic precautions the operation is almost entirely free from risk; and when the organs are healthy the closure of both the upper and the lower segments of the tubes is effected, and no retention of secretions need be feared as a result of the operation.
With regard to the indications for the performance of this operation, Kehrer insists that it should be undertaken only in cases of serious disease, and when the pros and cons have been conscientiously weighed. A consultation is also indispensable. Moreover, it is essential that husband and wife should both fully understand the nature of the proposed operation, and should form an unbiassed judgment regarding its advisability. To avoid any possibility of subsequent reproaches, Kehrer advises that a written report should be drawn up, giving the reasons for undertaking the sterilization, and that this should be subscribed by the physicians in consultation, by the patient herself, and by her husband.
Arndt considers that in cases in which there already exists serious constitutional disease, the performance of this operation may lead to fever, severe hæmorrhage, injury to adjacent organs, and even death. He holds, therefore, that in such cases the physician should advise the use of some of the more ordinary methods of preventing conception (if simple abstinence from intercourse cannot be practised). Only in women with pelvic contraction of the second or third degree, in whom previous children have been still-born, or subjected to craniotomy, is operative sterilization by Kehrer’s method justifiable. But in preference to anterior colpotomy, as recommended by Kehrer, he prefers the longitudinal incision in the posterior vaginal fornix advised by Boileux. If the uterus is drawn down firmly, and the portio vaginalis then pushed forward against the pubic symphysis, it is easy, at any rate with the assistance of a little abdominal pressure, to draw part of the Fallopian tubes into the vaginal incision.
Recently Pincus has recommended the cauterization of the uterine cavity with superheated steam (atmocausis, castratio uterina). He advises it only in women who are incurably ill (tuberculosis, morbus Brightii, hæmophilia), so that pregnancy and parturition would involve almost certain death.
Kossmann considers that when pregnancy and parturition will endanger a woman’s health and life, it is the physician’s duty to acquaint both husband and wife with this fact; but having done so his duty is fully discharged. “If, after being warned, the married pair choose to indulge in sexual intercourse, they have knowingly and voluntarily run into danger, and for this the physician is in no way responsible.”
