Fig. 1 (A) Uterine biopsy sample of an anestrus bitch (case No. 2) presenting slight fibrosis (arrow). (B) Uterine biopsy sample of a histologically normal anestrus bitch. Note the lack of collagen fibers (fibrosis) between endometrial glands. Hematoxylin-eosin-saffron stain (magnification × 200).

Fig. 2 Uterine biopsy sample of a bitch in late diestrus (No. 9). (A) Lymphocytic and neutrophilic endometritis (arrow head) are seen as increased cellularity in the area marked with the arrow head. (B) Suspicion of edema (black arrow) and moderate fibrosis and degeneration of the endometrial glands (*). Hematoxylin-eosin-saffron stain; (A) magnification × 100; (B) magnification × 200.

Fig. 3 (A) Uterine biopsy sample of a bitch in late diestrus (No. 13) presenting moderate lymphoplasmacytic endometritis (black arrow head) and slight pseudoplacentational endometrial hyperplasia (gland distension with similar other dilated glands, white arrow). (B) Uterine biopsy sample of a histologically normal late diestrus bitch. Note the lack of distension of the endometrial glands and the absence of inflammatory cells. Hematoxylin-eosin-saffron stain; magnification × 200. Theriogenology 2013 79, 312-322DOI: (10.1016/j.theriogenology.2012.09.005) Copyright © 2013 Elsevier Inc. Terms and Conditions
