The operation is limited to uteri not exceeding in size the head of a full-time fœtus.
In the impregnated females the uteri are filled with thousands of ova, each one of which encloses an embryo already well formed.Parasites

- The hollow, muscular organ of female mammals in which the embryo develops. In most mammals the uterus is divided into two saclike parts, whereas in primates it is a single structure. It lies between the bladder and rectum and is attached to the vagina and the fallopian tubes. During the menstrual cycle (estrus), the lining of the uterus (endometrium) undergoes changes that permit the implantation of a fertilized egg. Also called womb See more at menstrual cycle.
