In the portion of the cervix that remained there was a fistu-lous aperture opening into the abdominal cavity, through which semenpassed and produced an abdominal gestation. Several curious casesare also recorded, which have given rise to a good deal of discussion, inwhich a tubal pregnancy existed while the corpus luteum was on theopposite side (Fig. 76). The most probable explanation, however, is Fig. Tubal Pregnancy, with the Corpus Luteum in the Ovary of the opposite side. The Decidua isrepresented in the process of detachment from the Uterine Cavity. that the fimbriated extremity of the tube in which the ovum was foundhad twisted across the abdominal cavity and grasped the oppositeovary, in this way, perhaps, producing a flexion which impeded theprogress of the ovum it had received into its canal. Tyler Smithsuggested that such cases might be explained by supposing that theovum, after reaching the uterus, failed to graft itself in the mucousmembrane, but found its way into the opposite Fallopian thinks that such a passage of the ovum across the uterinecavity may be caused by muscular contraction of the uterus, occurringshortly after conception, squeezing the yet free ovum upwardstowards the opening of the opposite tube, and possibly into the tubeitself.
