* The endometrium shows considerable change during the oestrous cycle.
* In pro-oestrus and oestrus, endometrial glands are loosely coiled with obvious lumina and a deep epithelial lining.
* During metoestrus, the glads become larger. Lumina become smaller and the basal layer of the endometrium becomes more tortuous.
* As the bitch reaches anoestrus, there is a reduction in the number of glands and the amount that they coil.
* In metoestrus (~98 days after the onset of oestrus), there is desquamation of the endometrial epithelium.
* By day 120-130, the endometrium is restored by proliferation of cells from crypts of the endometrial glands.
