Cytological changes associated with the functions of the oviduct epithelium during proestrus and estrus in impala, Aepyceros melampus (Lichtenstein, 1812).

This study was carried out on the ampulla epithelium of the oviduct of impala of various ages. The morphological and ultrastructural features of the component epithelial cells were described. The cytological events which take place in the various cell types were documented and discussed. 2 cell types, the ciliated and nonciliated, constituted the cell population of the epithelium. The absence of glycogen in the epithelial cells was recognised.
