EFFECT OF TIOTRIAZOLINE ON STRUCTURAL AND FUNCTIONAL STATE OF THE OOCYTE-CUMULUS COMPLEXES AFTER PROLONGED HYPOTHERMIC STORAGE OF BOVINE OVARIES
The effect of prolonged hypothermic storage of bovine ovaries in Dulbecco medium supplemented with tiotriazoline on the morpho-functional state of oocyte-cumulus complexes |was investigated. It| is| established| that| preservation of high rate of oocyte that can survive in vintro favours the injection of tiotriazoline into the canned medium on early stages of ovary ishemization. In contrast, the presence of tiotriazoline only in storage medium has negative effect on nuclear maturation of oocytes.
