Delayed fertilization is common in cycles with immature oocytes. This phenomenon was observed in 42 of 423 with mature oocytes. Of the 42 cycles, 16 were excluded because of the presence of sperm autoantibodies. Sperm parameters of the remaining 26 (6.1%) cycles (group A) were compared with those in cycles with no fertilization at all (group B) and those in the control group (group C). The percentage of normal forms was 15% in group B and 24% in group A compared with 51% in group C. Fertilization rates were 32% in group A compared with 81% in group C. The incidence of poor embryonic morphology was 82% in group A compared with 29% in group C. Delayed fertilization and poor embryonic morphology associated with impaired sperm quality is of clinical and prognostic importance.
在卵母细胞不成熟的周期中，延迟受精很常见。在423个有成熟卵母细胞的周期中，有42个观察到了这种现象。在这42个周期中，有16个因存在精子自身抗体而被排除。将其余26个（6.1%）周期（A组）的精子参数与完全未受精的周期（B组）以及对照组（C组）的精子参数进行比较。B组正常形态的百分比为15%，A组为24%，而C组为51%。A组的受精率为32%，而C组为81%。A组胚胎形态不良的发生率为82%，而C组为29%。与精子质量受损相关的延迟受精和胚胎形态不良具有临床和预后意义。
