Influence of Oocytes First Polar Body Morphology on the Intracytoplasmic Sperm Injection
Abstract：Objective:To investigate the influence of the oocytes first polar body morphology on the fertilization rate and embryo quality in the intracytoplasmic sperm injection.Methods:60 infertile couples were as research objects,were divided into A,B,C group based on the oocytes first polar body morphology,fertilization and embryo development differences were compared.Results:After oocytes fertilization,85.0%of ertilized ovum was 3 score in group A,was significantly higher than that in group B(55.0%) and group C (25.0%),and there was statistically significant(P<0.05).Embryos with A-class in group A was account for 65.0%,significantly higher than that in group B(40.0%) and group C(10.0%),embryos with C-class was accounted for 5.0%,significantly lower than that in group B(20.0%) and group C(35.0%),there was statistically significant(P<0.05).Conclusion:When carring out ICSI,selecting oocytes according to the first polar body,can significantly improve the fertilization rate,to ensure the embryo quality.
