P-101: Effects of Ethanol and Strontium on Growth and Development of Two-Cell Arrested Mouse Embryos
نویسنده
چکیده مقاله:
Background: Arresting in a certain step of development like two-cell stage could be one of the reasons of infertility. The aim of this study is evaluating the effects of ethanol and strontium on growth and development of two-cell arrested mouse embryos. Materials and Methods: The females were coupled with male following superovulation. Positive vaginal plug mice were killed 48 hours after hCG injection. Two-cell embryos were transferred to M16 medium and divided to four groups. The first group is incubated without any exposure to low temperature. Groups 2, 3 and 4 were exposed to 4°C for 24 hours. The second group was incubated immediately, while the third and fourth groups were exposed to strontium and ethanol for five minutes respectively. Results: The data analysis by one-way ANOVA shows that developmental rate is decreased significantly by 4°C exposure. The mean of degenerated embryo was significantly different between groups but the mean cleavage rate hasn't any significant differences. The mean percent of morula, blastocyst and hatched blastocyst formation were significantly different between groups in 120 hours study. Conclusion: The effect of strontium and ethanol on arrested two-cell embryos hasn,t any significant differences on the mean percent of morula, but ethanol increase the mean percent of blastocyst and hatched blastocyst formation significantly more than strontium.
