目的:探究精子因素对高龄IVF-ET术受精率的影响。方法:选取接受IVF-ET治疗的患者180例,按照受精率分为完全受精失败组、低受精率组和正常对照组。男性高龄患者采集精子后,观察计数,计算精子浓度、向前精子活动率及正常形态率,并采用方差分析法进行分析。结果:TFF组的受精率、精子浓度、向前精子活动力和精子正常形态率均低于LFR组和NFR组,结果有统计学意义(P<0.05)。结论:精子浓度、向前精子活动率和精子正常形态率均影响IVF-ET的成败,临床上可通过常规检测给出客观治疗方案供患者选择。降低受精失败率。
Objective: To investigate the influence of sperm factors on the fertilization rate of elderly IVF-ET patients. Methods: One hundred and eighty patients treated with IVF-ET were enrolled. According to the fertilization rate, they were divided into complete fertilization failure group, low fertilization rate group and normal control group. After collecting sperm in elderly men, the counts were counted, sperm concentration, sperm motility and normal morphology rate were calculated and analyzed by analysis of variance. Results: The fertilization rate, sperm concentration, sperm motility and sperm normal morphology in TFF group were lower than those in LFR group and NFR group (P <0.05). Conclusion: The sperm concentration, the rate of forward sperm motility and the normal morphology of sperm all affect the success or failure of IVF-ET. Clinically, we can provide objective treatment options for patients to choose from. Reduce the failure rate of fertilization.
