PAN Chengshuang,ZHANG Huan,XU Zhihui, et al. The effect of surgical sperm extraction timing on the clinical outcomes of intracytoplasmic sperm injection[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2020, 50(4): 295-299.
Abstract：Objective: To investigate the effect of surgical sperm extraction timing on the clinical outcomes of intracytoplasmic sperm injection (ICSI). Methods: Totally 839 cases of surgically obtained sperm were analyzed for fresh cycle of ICSI treatment. According to the operation time, they were divided into ICSI group on the day of sperm extraction and ICSI group on the next day. The fertilization rate, cleavage rate, high quality embryo rate, implantation rate, clinical pregnancy rate, abortion rate and other results were compared between the two ICSI groups. Results: Embryo culture in vitro and clinical results showed that there was no significant difference in fertilization rate, maturation rate, cleavage rate, D3 quality embryo rate, implantation rate, clinical pregnancy rate and abortion rate between ICSI group on the day of surgical sperm extraction and ICSI group on the next day (P>0.05). Conclusion: The surgical sperm extraction time has no significant effect on the clinical outcomes of intracytoplasmic sperm injection.
