PURPOSE To explore the effects of traditional vs. intracytoplasmic sperm injection (ICSI) insemination method on the outcome of high-quality blastocyst development in a split sibling oocyte cohort. METHODS In this retrospective cohort study, we analyzed 62 ICSI/IVF split cycles. Sibling oocytes were randomly assigned to ICSI or IVF insemination. Two hundred thirty-four ICSI-only cycles and 152 IVF-only cycles were also analyzed for comparison. Blastocysts were graded by Gardner's embryo grading and were considered a high-quality blastocyst if 3BB or better (Gardner 1999). RESULTS In the ICSI/IVF split group, (1) ICSI oocytes had a higher fertilization rate per oocyte allocated (73% vs 62%, p < 0.001), (2) more high-quality day 2 embryos (69% vs 55%, p < 0.005), (3) ICSI oocytes had a lower blastulation rate per 2PN (46% vs 54%, p < 0.05), but a higher blastulation rate when calculated per oocyte allocated (40% vs 32%, p < 0.05). The ICSI-only group had a lower fertilization rate (65% vs 70%, p < 0.001) but more high-quality day 2 embryos in comparison to the IVF-only group (68% vs 64%, p < .05). The total high-quality blastulation rate was higher for the IVF-only group per 2PN (49% vs 43%, p < 0.05) and per oocyte retrieved (34% vs 28%, p < 0.05). CONCLUSIONS This distinctive IVF/ICSI sibling oocyte split design demonstrated a higher-quality blastulation rate in the IVF group compared to the ICSI group when calculated per 2PN, but not per oocyte allocated to each insemination procedure.

胞浆内的精子(ICSI)是否优于传统的体外受精(IVF):使用分体授精设计确认了每个卵母细胞的胚泡率更高。

目的探讨传统的与胞浆内精子注射(ICSI)人工授精方法对同胞卵母细胞队列中高质量胚泡发育的影响。方法在这项回顾性队列研究中,我们分析了62个ICSI / IVF分裂周期。兄弟卵母细胞被随机分配给ICSI或IVF人工授精。还分析了234个仅ICSI周期和152个仅IVF周期进行比较。囊胚根据Gardner的胚胎分级进行分级,如果3BB或更高,则认为囊胚为优质囊胚(Gardner 1999)。结果在ICSI / IVF分裂组中,(1)ICSI卵母细胞的每个卵母细胞受精率更高(73%vs 62%,p <0.001),(2)更多高质量的第2天胚胎(69%vs 55%) ,p <0.005),(3)ICSI卵母细胞每2PN的囊胚形成率较低(46%vs 54%,p < 0.05),但按分配的每个卵母细胞计算时,则有较高的成球率(40%vs 32%,p <0.05)。与仅IVF组相比,仅ICSI组的受精率较低(65%vs 70%,p <0.001),但第二天的胚胎质量更高(68%vs 64%,p <.05)。仅IVF组每2PN(49%vs 43%,p <0.05)和每卵母细胞回收的总高质量成团率更高(34%vs 28%,p <0.05)。结论按2PN计算时,IVF / ICSI同胞卵母细胞分裂设计与ICSI组相比,在IVF组中表现出更高的破胚率,但对于分配给每个授精程序的卵母细胞却没有。001),但与仅IVF组相比,第2天的胚胎质量更高(68%vs 64%,p <.05)。仅IVF组每2PN(49%vs 43%,p <0.05)和每卵母细胞回收的总高质量成团率更高(34%vs 28%,p <0.05)。结论按2PN计算时,IVF / ICSI同胞卵母细胞分裂设计与ICSI组相比,在IVF组中表现出更高的破胚率,但对于分配给每个授精程序的卵母细胞却没有。001),但与仅IVF组相比,第2天的胚胎质量更高(68%vs 64%,p <.05)。仅IVF组每2PN(49%vs 43%,p <0.05)和每卵母细胞回收的总高质量成团率更高(34%vs 28%,p <0.05)。结论按2PN计算时,IVF / ICSI同胞卵母细胞分裂设计与ICSI组相比,在IVF组中表现出更高的破胚率,但对于分配给每个授精程序的卵母细胞却没有。
