Abstract
Ewes with a single corpus luteum (CL) had 61.8% of 351 CL in the right ovary; ewes with more than one CL had 55.5% of 667 in the right ovary (P=.05). Apparent percent embryo loss was 21.7 for 161 ewes with one CL in the right ovary, 26.4 for 106 ewes with one CL in the left ovary, 35.5 for 55 ewes with two CL in the right ovary, 31.0 for 87 ewes with one CL in each ovary and 40.6 for 32 ewes with two CL in the left ovary (P< .05). The percent of embryos that apparently migrated to the uterine horn on the opposite side of the body to the ovary from which the egg originated was 10.3 of 126 embryos where one CL was in the right ovary, 7.7 of 78 with one CL in the left ovary, 32.4 of 71 with two CL in the right ovary, 0 of 120 with one CL in each ovary, and 26.5 of 38 embryos where there were two CL in the left ovary.
