Title:Az endometrium-biopszia szerepe és alkalmazása a nem vemhesülő kancák vizsgálatában az állatorvosi gyakorlatban - Irodalmi összefoglaló I. rész
SUMMARY Background: The management of non-pregnant, subfertile broodmares causes a significant expense in horse breeding. Beyond the routine physical and sono-graphic examination, advanced techniques are available for diagnosing subfertility (microbiology, endometrial biopsy) in mares for detecting inflammatory and degenerative changes of the endometrium. Objectives: The aim of the authors was to summarize the available information about the usefulness of endometrial biopsy sampling in mares in connection with barrenness. Furthermore, a special attention has been paid to the recently discovered investments in the diagnosis of endometrial problems in the mare.Material and method: Review and study papers have been summarized with the aim of scientific databases (www.sciencedirect.com; www.pubmed.com) from 1978 until 2017. The following keywords have been used in searching: endometrial biopsy, mare, barren mares, endometritis, endometrosis (endometriosis), fibrosis.Results and discussion: According to our experience and the available veterinary literature, in case of infertility/subfertility of broodmares of high value, the use of advanced examination techniques is suggested in order to detect subclinical diseases; however, a single examination is not sufficiently enough to estimate the fertility of a broodmare.
