Abstract
The tunica mucosa of infundibulum of the buffalo was highly branched with primary, secondary and tertiary folds occupying the greater part of the lumen during the follicular phase. During luteal phase, cytoplasmic protrusion and nuclear extrusion were distinct in the ampulla which also shows lymphocytic infiltration. During pregnancy, the mucosal folds were less prominent. The muscle layer gradually increased in size towards uterotubal junction. No cyclic variation was observed in the epithelial cells of the isthmus. The histological features of pregnant oviduct resembled the features observed during the luteal phase. The PAS-positive material revealed metachromasia and protein, suggesting carbohydrate-protein complex nature of secretion from epithelial cells of the oviduct.
