ABSTRACT

A post mortem study was conducted on 180 stray dogs at the Pathology Department of the College of Veterinary Medicine at the Universidad Nacional Autonoma de Mexico. Fifty bitches were in a follicular phase and 75 in a luteal one; the rest were discarded. A gross and microscopic study was conducted on each selected bitch. The presence of lesions was recorded, as well as the type, frequency and possible relationship with the estrus cycle. Lesions were classified as: cystic, neoplasic, of hormonal origin and congenital ones; cystic being the most frequent. There was no apparent hormonal influence on the presence of paraovarian uterine cysts, however, follicular and luteal cysts presented a clear estrogenic or progesterone influence, respectively. Hormonal activity did not have any influence on the pathology of neoplasic or congenital lesions. However, for some lesions, like hydrometra, a hormonal influence has not been clearly established.
