Endometrial Cytology in the Diagnosis of Uterine Pathology in Canines

Abstract

Endometrial cytology reflects the structural and physiological status of the endometrium in bitches. Forty bitches brought with the history for breeding management, uterine pathology and infertility were taken for the study and divided into four groups (n=10 each) as Group I,II,III and IV which included animals with normal reproductive capacity at any stage of estrus cycle (proestrus, estrus, diestrus and anestrus), cystic endometrial hyperplasia (CEH), pyometra and animals with reproductive failure (failed to conceive even after 3 consecutive cycles of breeding with proven male dogs) respectively. The study proved that the cellular pattern and morphological features in endometrial cytology changed throughout the reproductive cycle and in pathological conditions of pyometra and Cystic Endometrial Hyperplasia (CEH) with strong statistical variation. Endometrial cytology can be employed successfully as a diagnostic aid to detect infertility in bitches due to uterine pathology before the onset of clinical signs.
