* Anoestrous: low columnar-cuboidal, comprises of 2-3 layers.
* Pro-oestrus: high stratified squamous persists until late stages of oestrus.
* Stratum corneum and the layers immediately beneath it are lost by desquamation during pro-oestrus and oestrus. This leaves low squamous epithelium, which becomes converted to columnar epithelium 1-3 weeks after the end of oestrus.
* Metoestrus and pregnancy: high columnar, higher than during anoestrus.
* During pro-oestrus, oestrus and early metoestrus, the epithelium and lamina propria are infiltrated with large numbers of neutrophils, which eventually escape into the vaginal lumen.
