Three different methods were used for freezing human excess oocytes (320 frozen, 205 thawed) in our IVF programme and the results of these methods were compared. A high fertilization rate (75%) could be achieved after thawing, using 1,2 propanediol as a cryoprotectant. Polyploidy rates of 20% and 40% were observed using DMSO and 1,2-propanediol as cryoprotectants, respectively. Using the ultracooling method, the survival rate was poor (4%).
在我们的体外受精项目中，使用了三种不同的方法冷冻人类多余的卵母细胞（冷冻320个，解冻205个），并比较了这些方法的结果。使用1,2 - 丙二醇作为冷冻保护剂解冻后可实现较高的受精率（75%）。分别使用二甲基亚砜（DMSO）和1,2 - 丙二醇作为冷冻保护剂时，观察到多倍体率分别为20%和40%。使用超低温冷却方法时，存活率较低（4%）。
