The bovine oviduct provides the environment for sperm transport and capacitation, oocyte transport and maturation, fertilization and early embryonic cleavage. Gamete interactions in the tube occur in contact with both the tubal epithelium and the oviduct fluid secreted by these cells. Current research continues to reveal the active role the oviduct and its products play in normal fertilization and embryo development. This paper reviews the anatomy and physiology of the oviduct of the cow, including the specific events of reproduction which occur in this organ.
