We report here the results of a study comparing the quality of the embryos obtained after conventional IVF and after ICSI (respectively 872 and 459 embryos for 184 and 108 cycles). In the ICSI group, the female age was lower than in the IVF group, the oestradiol level on the day of hCG injection was higher, so that the number of retrieved oocytes and the number of mature oocytes. The policy of transfer being the same in the two groups, the mean number of transferred embryos was identical. The percentage of embryos without anucleate fragments, the percentage of embryos without irregularities, the percentage of 1, 2, 3, 4 or 5-cell embryos and the distribution of embryos in the 5 embryo scores were similar. In both IVF and ICSI groups, the transfer score (sum of the embryo scores of each transferred embryo) was higher for the patients who achieved pregnancy.
我们在此报告一项研究的结果，该研究比较了常规体外受精（IVF）和卵胞浆内单精子注射（ICSI）后获得的胚胎质量（分别为184个周期的872个胚胎和108个周期的459个胚胎）。在ICSI组中，女性年龄低于IVF组，人绒毛膜促性腺激素（hCG）注射日的雌二醇水平较高，因此回收的卵母细胞数量和成熟卵母细胞数量较多。两组的移植策略相同，移植胚胎的平均数量相同。无核碎片胚胎的百分比、无异常胚胎的百分比、1、2、3、4或5细胞胚胎的百分比以及5个胚胎评分中胚胎的分布相似。在IVF组和ICSI组中，成功怀孕的患者的移植评分（每个移植胚胎的胚胎评分总和）更高。
