The aim of this studywas to evaluate lesions of the genital tract in animais used as oocyte donors. Gir breed cows (n=20) used in different experiments involving the ovum pick-up technique were evaluated. At the end of each experimental period the animais were examined by rectal palpation, ultrasonography and vaginoscopy. A group of cows (n=8) were selected for histopathologic characterization of ovarian lesions. Ovaries were surgically removed, fixed and processed for histological examination. The cows evaluated underwent 9 to 42 puncture sessions, and yielded 10 to 719 oocytes. There was a low prevalence (5.26%) of inflammatory changes in the vagina mucosa. The occurrence of adherence was significantly correlated with the number of puncture sessions the animal underwent (r=0.31; P<0.05), but not with the total of oocytes collected (r=0.03; P>0.05). The opposite was observed reganding ovarian fibrosis, which showed a high correlation with oocyte yield (r=0.53; P<0.05). Histopathologic evaluation revealed scar tissue, inflammatory cell infiltration and presence of luteal tissue dispersed within the ovarian stroma. |
