- The oocyte survival rate of ICR mice reaches 75.2% after thawed. The fertilization rate reaches 24.6% and the difference is not remarkable compared to the control. But the oocyte survival rate of C37 BL/6J mice reaches 87.1% after thawed. 结果DEFS40冷冻液冷冻效果明显高于EFS40冷冻液;ICR小鼠卵母细胞解冻后成活率达75.;2%25、体外受精率(24
- The fertilization rate by SUZI was 29.2%,after 24h of further in-vitro culture,42.8% of these oocytedeveloped into embryos,two healthy offsprings with normal karyotypes were born after embryotransfer. 其中SUZI法的受精率达29.;2%25,卵裂率为42
- The fertilization rate of a majority of cycles((70.00)%,21/30) in group 2 was higher than 50%,and the mean of fertilization rates was(79.79)%. 改行ICSI后;大部分周期(70.;00%25;21/30)的受精率都在50%25以上;平均受精率为79
- After the mature oocytes were treated with BFA, the in vitro fertilization rate and rate of two-cell development to that of the control group also showed no significant difference (P>0.05). 另外;成熟卵母细胞经BFA处理后;其体外受精率及2-细胞率均与对照组差异无统计学意义(P>0.;05)。

- Results: As the decreasing score of the oocyte, the maturation rate, fertilization rate, cleavage rate and the quality of embryos decreased, meanwhile the apoptosis rate of granulose cells increased. 结果:随着卵母细胞评分的降低,卵子的成熟率、受精率、卵裂率及优质胚胎率均下降,而颗粒细胞的凋亡率升高。
- The fertilization rates and the cleavage rates of GV oocytes were significantly lower than that of the IVM oocytes (P<0.05). 冷冻程序和卵母细胞发育阶段对冷冻效果有明显影响,二步法冷冻效果显著优于一步法(P<0.;05),IVM卵母细胞冷冻效果显著优于GV期(P<0
