Title: Effect of Vitrification in OPS on in vitro Maturated Ovine Oocyte's Developmental Potential
Abstract: The present research was designed to investigate the effect of vitrification in EDFS30 by OPS on in vitro maturated ovine oocyte's developmental potential. Results were evaluated in terms of cleavage rate and blastocyst rate. The results showed that the parthenogenetically activated oocytes in vitrification group had a lower cleavage rates (64.2%) compared with toxicity group (76.7%) and control group (79.1%)(P 0.05), there was no difference between the toxicity group and control group(P 0.05); the blastocyst rates of parthenogenetically activated oocytes in vitrification group(4.2%) and toxicity group(5.8%) were decreased significantly than that of the control group (20.2%), and that was similar between the vitrification group and toxicity group(P 0.05); the rates of cleavage and blastocyst of the in vitro fertilization oocytes in vitrification group (67.6% and 7.1%) and toxicity group (62.3% and 9.1%) were higher than that of control group (78.4% and 28.4%)(P 0.05), and that was similar between the vitrification group and toxicity group(P 0.05). These results indicated that the developmental potential of the oocytes vitrified in EDFS30 by OPS could be decreased in some extent.
