Abstract: Corpora lutea (CL) of pregnancy from single-lambing ewes were examined by light and electron microscopy within 24 h and at 8, 15, 23, 31 and 41 days after parturition (2 ewes per stage). Within 24 h of parturition the structure of the CL was well preserved and both large and small luteal cells, characteristic of this species, were present in substantial numbers. However, both types of luteal cell contained numerous cytoplasmic lipid droplets, and smooth endoplasmic reticulum and secretory granules in large luteal cells were less prominent than in normal functional CL of cyclic ewes. Leucocytic infiltration, and death of some luteal and endothelial cells, were also observed at this stage. Further regression of the CL progressed slowly, and lipid-rich large luteal cells were still readily recognisable 15 days after parturition. The size of the CL declined progressively, and the proportion of tissue occupied by intercellular substances increased. Corpora albicantia approximately equal to 3-4 mm in diameter were still recognisable 41 days after parturition. It was concluded that luteal regression post partum progresses much less rapidly than at the end of the oestrous cycle. |
