The purpose of this study was to evaluate survival rates of vitrified mouse blastocysts in various vitrification solutions (cryoprotectants) and apparatuses. The mouse blastocysts were harvested from culture of mouse 2 cell embryo and were divided into three group (i) untreated (control); (ii) exposed to cryoprotectant agents; or (iii) cryopreserved by various vitrification apparatuses. Vitrification solutions are 40% ethylene glycol (EG) + 5.8 mg/mL ficoll + 0.5M sucrose (EFS solution), 3M glycerol + 3M EG (ES solution), 20% EG + 20% dimethyl sulfoxide (ED solution), 3M EG + 1.0 m sucrose (ES solution). Vitrification apparatuses consisted of 5 groups ; closed plastic straw (CPS), electron microscope (EM) grid, cryoloop, open pulled straw (OPS), and glass micropippete in plastic straw (GPS). The survival rates of control were 88.0%. The survival rates of exposed blastocysts in EFS, GE, ED, and ES solutions were 70.8%, 43.5% (P<0.01), 83.3% and 65.2%, respectively. The survival rates of vitrified blastocysts in CPS, EM grid, cryoloop, OPS and GPS were 56.5% (P< 0.01), 72.7%, 83.3%, 60.9% (P<0.05) and 54.2% (P<0.01), respectively. Among the vitrification solutions, the highest survival rate was seen in blastocysts vitrified in EG + DMSO (83.3%). The survival rate was not significantly different from that of the control (88%). Blastocysts cryopreserved with glycerol in all groups had an overall low survival rate of 43.5%. Survival rate of mouse blastocysts between vitrification apparatuses showed higher in cryoloop.
