目的比较使用不同精液处理方法对体外受精IVF周期结局的影响。方法回顾性分析2014年1月至2014年12月在我院生殖中心行IVF治疗,选取进行新鲜周期移植的病例,分为密度梯度离心结合上游法组(163例)和单纯上游法分离精子组(75例),对妊娠结局进行比较。结果两组之间的植入率、临床妊娠率、流产率、异位妊娠率等均未见明显差异;结论密度梯度离心结合上游法和单纯上游法分离精子进行IVF的妊娠结局没有明显差异,均是简单安全的分离精子的方法。
Objective To compare the effects of different semen treatments on IVF cycle outcomes in vitro. Methods A retrospective analysis of IVF treatment in our reproductive center from January 2014 to December 2014 was conducted to select fresh cycle transplantation cases. The patients were divided into density gradient centrifugation combined with upstream group (163 cases) and simple upstream group (75 cases), the pregnancy outcome were compared. Results There was no significant difference in implantation rate, clinical pregnancy rate, miscarriage rate and ectopic pregnancy rate between the two groups. Conclusion There was no significant difference in pregnancy outcome between IVF with density gradient centrifugation and simple upstream method for sperm isolation, Are simple and safe method of separating sperm.
