Imperforation of the external orifice of the cervix in a mare

An imperforation of the external uterine orifice in a mare is described. Su rgical repair of the neck was carried ut using a fiberscope and long handle d laparoscopic instruments. The cervix recovered its full functioning capac ity five weeks after the surgery. Microbiological analysis of the intrauter ine fluid, revealed no bacteria, and after the intrauterine flushing, the p eriglandular fibrosis and the nesting in the endometrium decreased signific antly. Finally, cytogenetic research determined that our mare was a normal female (64 XX). Reproductive history microbiological analysis, and endometr ial features of the cervix, allow us to rule out the acquired nature of thi s anomaly.
