ABSTRACT:
A method is disclosed for implanting an embryo transplant from a donor mammal into the uterus of a recipient mammal. The method comprises making an incision in the lateral wall of the vagina of a recipient mammal posterior of the cervix. The uterine horn leading to an ovary having a corpus luteum thereon is positioned in proximity to the incision in the vaginal wall. The wall of the uterine horn is exposed through the incision in the vaginal wall. A hole is punctured through the exposed wall of the uterine horn. A cannula is inserted through the incision in the vaginal wall and through the hole in the wall of the uterine horn. The embryo transplant to be implanted in the recipient mammal is introduced through the cannula into the lumen of the uterine horn. After insertion of the embryo the cannula is withdrawn.
