The cellular composition of the human oviduct epithelium.

Epithelium from human Fallopian tubes was examined to determine the ratio of ciliated to secretory cells. A comparison was made between results from oviducts from women at different stages of the menstrual cycle, and also between the fimbrial, ampullary and isthmic regions of the oviduct. A high percentage of ciliated cells was found in each case, including the isthmic region, with little difference seen throughout the cycle. The role of cilia in ovum transport is discussed.
