Summary

The relationship between post-thaw exposure time in cryoprotectants and the viability of IVF-derived bovine embryos after culture was examined. Good- and excellent-quality day 7 to day 8 blastocysts and expanded blastocysts were frozen by the nonstepwise method using 1.6 M propylene glycol or ethylene glycol as the cryoprotectant. The authors' findings suggest that different post-thaw exposure times up to 30 min using propylene glycol or ethylene glycol as the cryoprotectant are not harmful to IVF bovine embryos.
