The innervation and vascular supply of the uterovaginal sperm-host glands of the domestic hen were investigated. No nerves were associated with these glands, although nerves were demonstrated in other regions of the oviduct.
The glands have a complex blood supply consisting of a capillary network connected to the arterial and venous systems and to the epithelial capillary plexus. The capillaries of the glands are in intimate contact with the cells over relatively great lengths.
The possibility of the vascular system being in some way related to the control of the function of the glands is discussed.
