Summary.

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.

Summary.

Histochemical tests in the uterovaginal region of the mature domestic fowl have demonstrated that sperm-host glands, and to a lesser extent transitional glands, contain glycogen. Uterine glands and epithelial tissue contain either no carbohydrate or only mucopolysaccharides. The host glands contained a lipid in granules which is presumably secretory; this may be an atypical phospholipid or one which is present as a complex with other substances. No discrete sites of protein synthesis were observed. They also secrete acid phosphatase but not potassium. The functions of these substances have not yet been determined.

Summary.

The effect of a surgical thread placed in the uterus (shellgland) on the function of the sperm-host glands was investigated. It was confirmed by histological examination that treated birds, whether inseminated before or after surgery, had fewer spermatozoa in the glands than did untreated birds. No effect on the glandular secretions was revealed. These observations are discussed in relation to glandular function and the survival of spermatozoa within the oviduct.
