High survival rate of sheep produced blastocysts vitrified with a new method and device.

Background: To advance the use of embryo vitrification in veterinary practice, we developed a system in which embryo vitrification, warming and dilution can be performed within a straw. Ovine produced embryos (IVEP) were vitrified at either early (EBs:  = 74) or fully expanded blastocyst stage (FEBs:  = 195), using a new device named "E.Vit", composed by a 0.
