The morphological changes in the post partum corpus luteum was investigated by light microscopy on 16 ewes during the normal breeding season (March/April). The increase in luteal tissue results from hypertrophy and not from hyperplasia of the granulosa and thecal cells. Two types of lutein cells were found in the corpus luteum: a large light-staining cell and a small dark-staining cell. These might reflect the 2 extremes of a spectrum of cells in different functional states, or they might represent cell lines derived from the follicular granulosa and the thecal interna, respectively.
