[On the histotopochemistry of the uterovaginal region in the quail (Coturnix coturnix japonica) (author's transl)].
The surface epithelium of vagina, uterovaginal region and uterus as well as the uterine and uterovaginal glands of 18 mature female quails were studied with histochemical methods. As in other avian species also in the quail a storage of spermatozoa in the lightly coiled uterovaginal glands takes place. The functional specialization of these glands is underlined by their distinct enzyme pattern. A strong reactivity of enzymes from oxidative pathways and of adenosine triphosphatase between epithelium and glandular luminal content. Alkaline phosphatase in the glandular epithelium was observed only when an egg is transported through the uterovaginal region. As in other vertebrate sperm storing sites also in the uterovaginal region of the quail the presence of a strong steroid dehydrogenase activity is registered.
