Cell embryos were cultured in vitro, then viability was observed. The results showed the fertilizing rate in vitro of the group for GV oocytes with cumulus cells after maturating which were conserved at 10℃ for 24 h, 15℃ for 14 h, 20℃ for 8 h and 25℃ for 4 h was 14%, 9%, 10% and 10% respectively, and with the advance of storage temperature and extension of storage time, the rate of 2-cell after maturating-fertilizating of the GV oocytes decreased significantly.

其结果，在10℃下保存24h、15℃下保存14h、20℃下保存8h和25℃下保存4h后，其体内附有卵丘细胞的GV卵的体外成熟－体外受精后的2细胞率分别为14%、9%、10%和10%，随着保存温度的提高和保存时间的延长，带有颗粒细胞GV期卵的比率明显降低，同时其GV期卵经体外成熟及体外受精后的2细胞率明显降低。

When oocytes were matured at 37-39℃,the appearance of cumulus cell had protective effect on cleavage and blastocyst rate,the development rate of DOs significantly decreased compared to COCs.

当卵母细胞在37-39℃成熟培养时，卵丘细胞对卵母细胞的发育有一定的保护作用，DOs的发育能力显著低于COCs。
