perivitelline space

Moreover , percentage of oocytes with perivitelline space granularity were significantly higher than those in intermediate dose and low-dose groups ( 40.2 % vs 17.5 % , 23.2 % , P < 0.01 ) .

高剂量组卵母细胞卵周隙内出现颗粒比例也明显高于低中剂量组（40.2%vs17.5%、23.2%，P<0.01）。

The blastomeres separated from the embryos were injected into the perivitelline space of enucleated secondary oocytes under the control of micromanipulator .

在显微操作仪的控制下，将分离后的单个卵裂球注入去核次级卵母细胞的卵周隙。

After fertilization membrane was lifted , the secondary egg emitted the second polar body into the perivitelline space .

受精膜举起后，由次级卵母细胞排放出第二极体。

Present data indicates that , oocyte morphology , including the shape of the first polar body and the size of perivitelline space , reflects the maturity of the oocytes and may have a predictive value on the ability of fertilization following ICSI .

因此推测，卵母细胞的第一极体形态和卵周隙大小反映了卵母细胞的成熟度，受精前观察卵母细胞第一极体和卵周隙的形态可以预测ICSI后的受精能力。
