The light microscopic of Corpus luteum and the different cell types in the functional corpus luteum of the bat were
studied. Two types of luteal cell,a large and small, were present in the corpus luteum of this species of bat. The large more
rounded luteal cell. Cytoplasm is granular and vacuolizations are observed in most of the cells The luteal cells are compactly
arranged and show moderate hypertrophy. Nuclei are distinct and darkly stained with Chromatin clumps. During late pregnancy
luteal cells are shrunken. Intracellular spaces in the corpus luteum have increased. Small vacuoles are also seen in the
cytoplasm of the luteal cells. The process of luteolysis has been initiated in the luteal cells Small luteal cell present amongs the
large luteal cells with tapering cytoplasmic processes.
