摘要
目的分析体外受精(IVF)周期受精低下的原因及妊娠结局。方法观察IVF受精低下83周期(受精低下组),以同期受精正常的1,717个IVF周期为对照组,比较两组的卵裂率、优质胚胎率、种植率、临床妊娠率、流产率;同时观察不同促排方案对受精低下的影响。结果两组不同促排方案的受精低下比率无显著差异(P>0.05);卵裂率、优质胚胎率、种植率、临床妊娠率、流产率也均无显著差异(P>0.05)。结论促排卵方案不是影响受精低下的因素,受精低下周期中获得的胚胎质量及发育潜能没有影响。
Objective： To analyze the possible reason and pregnancy outcomes of low fertilization rate cycle of in vitro fertilization （IVF） treatment. Methods： Eighty-three IVF cycles with low fertilization rate were retrospectively studied, with 1,717 cycles with normal fertilization rate during the same period as control. Cleavage rate, good embryo rate, clinical pregnancy rate, implantation rate and abortion rate were analyzed. The possible association of different ovarian stimulation protocols with low fertilization cycles was studied. Results： There was no significant difference in the incidence of low-fertilization-rate cycle between different stimulation protocols （P〉0.05）. The rates of cleavage, good embryo, implantation, clinical pregnancy or abortion were not significantly different between low fertilization rate cycles and normal control cycles （P〉0.05）. Conclusions： Ovarian stimulation protocol was not an influencing factor of low fertilization rate, and low fertilization rate did not have much impact on embryo quality and development potential.
