Introduction: A high concentration of polyvinylpyrrolidone (PVP, average molecular weight 360 000) supplementation in culture medium exerts a positive influence on the growth and morphological organization of bovine oocyte–cumulus/granulosa cell complexes in a long-term culture. The objective of the present study was to determine the effect of PVP supplementation on the number of transzonal projections (TZPs) traversing the zona pellucida from cumulus cells to the oocyte....
