Abstract
The ovary in which a CL [corpora lutea] was observed by laparoscopy in Finnish Landrace, Tasmanian Merino and Scottish Blackface ewes had no apparent effect on the location of the CL during the succeeding estrous cycles, on the duration of the associated estrous cycles, or on the peripheral progesterone concentrations on Days 7 and 11. Although 53% of CL were present in the right ovaries, the difference between the 2 sides was not significant.
