Survival rate of frozen-thawed bovine IVF embryos in relation to exposure time using various cryoprotectants.

Abstract

The relationship between cryoprotectant and exposure time on the development of IVF-derived embryos in culture after freezing and thawing was examined. Good to excellent quality Day 7 to 8 blastocysts and expanded blastocysts were suspended in 1.6 M propylene glycol (PG), 1.8 M ethylene glycol (EG), 1.1 M diethylene glycol, and 1.3 M ethylene glycol… (More)
