Abstract The "utero-vaginal junction" that connects the uterus and vagina of duck oviduct differs histologically and histochemically from the adjacent zones. The region is characterised by low, somewhat longitudinally arranged mucosal folds, lined by tall columner cilliated cells with apical nuclei alternating with mucous secreting goblet cells containing basal nuclei. Within the propria of the mucosa there are numerous tubular glands--the sperm host glands--which are responsible for sperm storage after copulation. The goblet cells of the utero-vaginal junction contain an admixture of neutral, sulfated and nonsulfated acid mucopolysaccharides, while the sperm host glands are devoid of any mucopolysaccharide and secrete complex lipoidal materials and exhibit intense acid phosphatase activity. The functional significance of the secretory materials of the sperm host glands have been discussed in the light of sperm release mechanism.
