There are many cases of stricture or complete occlusion of the vagina, congenital or acquired from cicatricial contraction, obstructing delivery, and in some the impregnation seems more marvelous than cases in which the obstruction is only a thin membranous hymen. Often the obstruction is so dense as to require a large bistoury to divide it, and even that is not always sufficient, and the Cesarean operation only can terminate the obstructed delivery; we cannot surmise how conception could have been possible. Staples records a case of pregnancy and parturition with congenital stricture of the vagina. Maisonneuve mentions the successful practice of a Cesarean operation in a case of congenital occlusion of the vagina forming a complete obstruction to delivery. Verdile records an instance of imperforate vagina in which rectovaginal wall was divided and the delivery effected through the rectum and anus. Lombard mentions an observation of complete occlusion of the vagina in a woman, the mother of 4 living children and pregnant for the fifth time. Thus, almost incredible to relate, it is possible for a woman to become a mother of a living child and yet preserve all the vaginal evidences of virginity. Cole describes a woman of twenty-four who was delivered without the rupture of the hymen, and Meek remarks on a similar case. We can readily see that, in a case like that of Verdile, in which rectal delivery is effected, the hymen could be left intact and the product of conception be born alive. A natural sequence to the subject of impregnation without entrance is that of artificial impregnation. From being a matter of wonder and hearsay, it has been demonstrated as a practical and useful method in those cases in which, by reason of some unfortunate anatomic malformation on either the male or the female side, the marriage is unfruitful. There are many cases constantly occurring in which the birth of an heir is a most desirable thing in a person's life. The historic instance of Queen Mary of England, whose anxiety and efforts to bear a child were the subject of public comment and prayers, is but an example of a fact that is occurring every day, and doubtless some of these cases could be righted by the pursuance of some of the methods suggested.
