The endometrial biopsy in the mare with regard to clinical correlations

Based on own experiences completed by literature informations the possible endometrial biopsy findings in mares are reviewed. The signifi cance of this technique is explained taking clinical aspects into account. New results dealing with endometrosis, angiopathies and functional endometrial lesions are described. Built on the system established by Kenney and Doig (1986) new model for the assessment of biopsy findings is presented in this paper.
