The Influence of Polyvinypyrrolidone on Freezing of Bovine IVF Blastocysts Following Biopsy

Abstract

A Study was conducted to develop a better freezing protocol for in vitro developed biosied blastocyst. Biopsied blastocysts exposed to 1.8 M ethylene glycol (EG) + 0.05 M trehalose (T) and different concentration (5,10, and 20%) of polyvinylpyrrolidone (PVP).
