Comparative Observations on Ciliary Currents in Mammalian Oviducts

P. GADDUM-ROSSE 1, and R. J. BLANDAU 1

Oviducts of four mammalian species (cow, sheep, guinea pig and rat) were slit open longitudinally, while submerged in Hanks’ balanced salt solution at 37°C, in order to expose the lining mucosa. The direction of ciliary currents on the mucosa was assessed by applying particulate matter (15 µm microspheres or stained lycopodium spores) to the surface. In cow and sheep oviducts, the particles were transported toward the uterine end when applied to either the ampulla or the isthmus, in contrast to the pro-ovarian ciliary currents demonstrated earlier in the isthmus of pig and rabbit oviducts. No ciliary currents could be detected in the isthmus of guinea pig and rat oviducts. Scanning electron microscopy revealed the extreme scarcity of ciliated cells in the isthmus of the latter two species. It is concluded that the significance of ciliary activity for gamete transport in the isthmus of the oviduct varies remarkably among species. Sperm transport is most likely achieved by a mechanism independent of ciiary action.
