【摘要】目的 觀察提前去除卵丘細胞對胚胎質量的影響，進一步探討其臨床應用價值。方法將2009年7-9月行體外受精-胚胎移植治療的患者隨機分為兩組，試驗組共137個周期，于授精后5 h去除卵丘細胞；對照組共146個周期，于授精后16～18 h去除卵丘細胞。兩組均于授精后16～18 h觀察受精情況，72 h對胚胎進行評分，選擇1～3枚優質胚胎進行胚胎移植。分別比較兩組的年齡、不育年限、獲卵數、受精率、卵裂率、優質胚胎率、胚胎種植率和臨床妊娠率。結果兩組的優質胚胎率差異有統計學意義（P lt;0.01）；但年齡、不育年限、獲卵數、受精率、卵裂率、胚胎種植率和臨床妊娠率比較，差異均無統計學意義（P gt;0.05）。結論體外受精中提前去除卵丘細胞優質胚胎增加，有助于提高臨床累積妊娠率。
【Abstract】 Objective To evaluate the effect of denuding the oocyte granulose cells soon after fertilization in vitro (IVF). Methods A total of 283 IVF cycles in patients from July to September 2009 were divided into a trial group and a control group randomly. The trial group contained 137 cycles, being denuded the oocyte granulose cells only 5 hours after IVF. The controlled group contained 146 cycles, being denuded the oocyte granulose cell and observed the pronuclear 18 hours after IVF. The outcomes of female age, infertile duration, the number of oocyte, fertilization rate,abnormal fertilization rate, good quality embryo rate, and clinical pregnancy rate were measured. Results There was no difference in any of the outcomes between the two groups except for the high quality embryo rate (P lt;0.01). The clinical pregnancy rate was higher in the trial group without significant differences (P gt;0.05). Conclusions Denuding the oocyte granulose cells soon after IVF helps to improve the embryo quality and the clinical accumulated pregnancy rate.
