Nonsurgical Embryo Placement.
Preferred location for the nonsurgical placement of the embryo in the horn ipsilateral to the corpus luteum, at the level of the external bifurcation of the horn, about one-third of the distance up the horn. The tip of the transfer instrument can be seen through the incision in this slaughterhouse specimen. Deeper placement may be ideal, but excessive manipulation and trauma to the endometrium must be avoided.
