Sometimes one of them is so poorly developed that it looks like a rudimentary horn. Such a rudimentary horn may be the site of grafting and development of a fertilized egg. Pregnancy in this case usually proceeds according to the type of tubal pregnancy, but, due to the better development of the wall of the rudimentary horn of the uterus, rupture of the fetal receptacle either does not occur, or occurs at a later stage of pregnancy.</p>Kazan Medical ArchivesКазанский медицинский архив
