目的探讨畸精子症常规IVF和ICSI两种不同授精方式与临床结局的相关性。方法对2013年1月至2014年12月在我中心因单纯畸精子症因素(IUI治疗失败)行IVF-ET(in vitro fertilization-embryo transplant)治疗的患者,随机分为两组:常规体外授精(IVF)组及单精子卵胞浆内显微注射(ICSI)组。比较两组的受精率、卵裂率、优质胚胎率、妊娠率、流产率及活产率。结果 IVF组与ICSI组患者的各项指标为:受精率(78.2%vs70.1%),卵裂率(94.0%vs96.1%)优质胚胎率(49.5%vs47.7%),妊娠率(43.6%vs46.0%),目前流产率(13.6%vs21.0%),婴儿出生率(70.5%vs66.7%),继续妊娠率(15.9%vs12.3%)。结论单纯畸精子症因素行IVF-ET治疗的患者,在授精方式可以选择IVF方式。
Objective To investigate the correlation between routine IVF and ICSI routine spermatozoa and their clinical outcomes. Methods From January 2013 to December 2014, patients undergoing IVF-ET (simple in vitro fertilization-embryo transplant) treatment in our center were divided into two groups randomly: conventional in vitro fertilization (IVF) group and intracytoplasmic sperm injection (ICSI) group. The fertilization rate, cleavage rate, quality embryo rate, pregnancy rate, abortion rate and live birth rate were compared between the two groups. Results The indexes of IVF group and ICSI group were fertilization rate (78.2% vs 70.1%), cleavage rate (94.0% vs 96.1%), high quality embryo rate (49.5% vs 47.7%), pregnancy rate 43.6% vs46.0%), current abortion rate (13.6% vs21.0%), birth rate (70.5% vs66.7%) and pregnancy rate (15.9% vs12.3%). Conclusion IVF-ET treatment of patients with simple teratospermia factors in the way of insemination can choose IVF way.
