Local Effect of the Early Sheep Embryo upon Uterine Motility¹

University of Wisconsin, Madison

Abstract

Uterine motility in bred and unbred ewes with unilateral ovulations was determined. Motility was measured by the distance traveled by small rubber pellets from a point of insertion within the uterine lumen near the tubo-uterine junction during the interval from day 3 to day 14 after estrus. The uterine horn containing the embryo displayed greater motility. No local effect of the ovary containing the corpus luteum upon the uterine motility of the ipsilateral horn was detected. The rubber pellets had an antifertility action when deposited in the same uterine horn as the embryo.
