Information about the mechanisms of meiotic arrest and resumption of meiosis in feline oocytes is still limited. The aim of this study was to investigate the effect of the presence of gonadotropins during IVM, on meiotic progression in relation to the status of gap junction mediated communications between oocyte and cumulus cells, to the cAMP intracellular(More)
Oocyte cryopreservation in carnivores can significantly improve assisted reproductive technologies in animal breeding and preservation programs for endangered species. However, the cooling process severely affects the integrity and the survival of the oocyte after thawing and may irreversibly compromise its subsequent developmental capability. In the(More)
The aims were to evaluate the suitability of a non-commercial TRIS-lecithin (LC) extender and the effect of different concentrations of catalase (CAT) on motility, capacitation status (Chlortetracycline-assay) and zona pellucida (ZP) binding capacity of canine spermatozoa stored at +5 degrees C for 4 days. The sperm-rich fractions of the ejaculates of four(More)
