description Contents The aim of this study was to investigate the morphological changes of the sow endosalpinx and the distribution of leukocytes throughout the oestrous cycle and at anoestrus. Nineteen crossbred sows (Swedish Landrace × Swedish Yorkshire) at late dioestrus (three), prooestrus (three), oestrus (three), early dioestrus (three), dioestrus (three) and anoestrus (four) were used. Oviductal samples from three different parts (isthmus, ampulla and infundibulum), taken immediately after slaughter, were fixed, embedded in plastic resin and stained with toluidine blue or stored in a freezer at −70°C until analysed by immunohistochemistry (prooestrus and anoestrus) with an avidin‐biotin peroxidase method. Quantitative and qualitative examinations of oviductal epithelium and subepithelial connective tissue were performed by light microscopy. During all stages, a lower degree of morphological changes (pseudostratification, mitosis and secretory granules) was found in the isthmus compared with ampulla and infundibulum. In ampulla and infundibulum, pseudostratification, mitotic activity and secretory granules of the epithelium were high at prooestrus/oestrus. Cytoplasmic protrusions of epithelial cells with some extruded nuclei were prominent in ampulla and infundibulum at all stages except for oestrus and early dioestrus. Lymphocytes as well as CD2‐ and CD3‐positive cells were the predominant immune cells in the epithelial layer. The numbers of lymphocytes and CD3‐positive cells did not differ among segments and stages. Numbers of CD2‐positive cells did not differ between prooestrus and anoestrus while the numbers were significantly higher in the infundibulum than in ampulla and isthmus. Neutrophils were only occasionally found and mainly in the infundibulum. In the subepithelial connective tissue layer, the two most commonly observed immune cell types were lymphocytes and plasma cells. The numbers of lymphocytes as well as CD2‐ and CD3‐positive cells was lower in isthmus than in the other segments (p ≤ 0.001). Higher numbers of plasma cells (p ≤ 0.001) were found in infundibulum than in ampulla and isthmus. The numbers of lymphocytes and plasma cells were not significantly different between stages of the oestrous cycle. However, the number of neutrophils differed and were highest at prooestrus in ampulla and infundibulum. The numbers of CD2‐, CD3‐ and CD79‐positive cells did not differ between prooestrus and anoestrus whereas for CD14‐ and SWC3‐positive cells, th
