Abstract：Objective:To study the relationship between the percentage of polypronuclear zygotes and clinical pregnancy following IVF. Methods:We collected the data of 954 IVF cycles,and according the percentage of polypronuclear zygotes in the IVF cycles,allocated them to Groups A(without polypronuclear zygotes),B(with<30%polypronuclear zygotes)and C(with≥30%pelypro-nuclear zygotes).Then we analyzed the relationship between the percentage of polypronuclear zygotes and the rate of clinical pregnan-cy. Results:Compared with Group A,Group C showed a significantly lower rate of clinical pregnancy(43.2% vs 28.1%,P<0.05),while Group B exhibited a markedly higher rate(43.2% vs 52.36%,P<0.05)and obviously decreased polypmnuclear zy-gote formation with the increase of age(35.6% vs 24.1%,P<0.05). Conclusion:The percentage of polypronuclear zygotes in IVF cycles may serve as a prognostic indicator of the clinical outcome.
