Testicular fluid is highly condensed during its passage through the epididymal region in the avian species. In the present study, major ion transporters that are responsible for condensation mainly by water resorption in the reproductive tract as identified in the mammalian epididymis were localized within the rooster (Gallus domesticus) epididymis by immunohistochemistry. The results show that the efferent ductule epithelium expressed sodium-potassium ATPase (Na(+),K(+)-ATPase), carbonic anhydrase II (CAII) and sodium hydrogen exchanger isoform 3 (NHE3) and that the connecting ductule and epididymal duct epithelia expressed Na(+),K(+)-ATPase and CAII. These data suggest that a model proposed for reabsorption in mammalian efferent ductules can be applied to avian efferent ductules.
