Lesiones histopatológicas más frecuentes en el endometrio de perras clínicamente sanas en diestro

Abstract

Las consultas por problemas de infertilidad/subfertilidad en la perra son frecuentes en la clínica reproductiva. En los últimos años, estudios realizados han mostrado que la endometritis subclínica (ES) podría ser una importante causa, por ello el objetivo de este trabajo fue estudiar el endometrio de perras clínicamente sanas. Se utilizaron 79 perras, pospúberes, cíclicas, en diestro, de entre 8 meses y 6 años de edad, clínicamente sanas. Las perras fueron divididas en tres grupos: perras que habían recibido tratamiento anticonceptivo con progestágenos (n=8), perras que nunca habían recibido tratamiento anticonceptivo (n=49), perras que se desconocía si habían recibido tratamiento anticonceptivo (n=22). Se tomó una muestra de cada cuerno uterino para estudio histopatológico mediante punch de 0,4 cm de diámetro. Las muestras fueron colocadas en tubos con solución formolada tamponada (pH 7.0/7.4) al 10% y remitidas al laboratorio. La observación de las mismas se realizó al microscopio óptico a 4X, 10X, 40X y 60X. De las 79 perras, 22 presentaron imagen histológica de útero normal, 47 ES, 7 hiperplasia endometrial quística y las 3 restantes presentaron otras afecciones. Nuestros resultados muestran que la ES podría ser la causa de gran parte de los problemas de infertilidad/subfertilidad en la perra.

Infertility and subfertility are common problems in small animal reproduction. In the last years some studies suggested that subclinical endometritis (SE) could be an important cause of infertility/subfertility. The aim was to study the endometrium in healthy bitches. Seventy nine bitches, clinically healthy, aged between eight months and six years old, in diestrous, have been included in this work. Bitches were divided in 3 groups G1: bitches treated with progestins (n=8), G2: bitches never treated with progestins (n=49), G3: bitches without data about the use of progestins (n=22). The dioestrus was determined based on the date of the last heat, the study of vaginal cytology and the presence of corpus luteous in ovary. A biopsy was obtained from each uterine horn, placed in 10% (pH 7.0/7.4) buffered formalin solution and processing for histopathology study. Samples were observed with an optical microscope at 4X, 10X, 40X and 60X. Twenty two bitches showed normal endometrium, 47 showed SE, 7 showed cystic endometrial hyperplasia and three bitches had other conditions. Our results suggest SE could be an important cause of infertility/subfertility in the bitch.
