Direct transfer of vitrified rabbit embryos.
In this study we looked at the feasibility of transferring vitrified rabbit embryos directly into recipient does. Compacted morulae were vitrified in a solution of 20% ethylene glycol and 20% dimethyl sulfoxide. After thawing, and without step-wise diluted solution, the vitrified embryos were transferred into the recipient's uterine horns. Survival rate at birth differed from fresh rabbit embryos (40% vs 55%, P < 0.05). However, the percentage of does that delivered (94%) and the survival rate suggested this method is suitable for both storage and simple transfer of rabbit morulae.
