- Abstract:
- The association between oocyte morphology and subsequent fertilization rate and embryo quality in intracytoplasmic sperm injection (ICSI) is subject to considerable controversy. This retrospective study was carried out to investigate a possible prognostic value of first polar body morphology with regard to fertilization rate and embryo quality. A total of 70 consecutive ICSI cases was included in this study. The results showed that classification based on first polar body morphology revealed a significant correlation with fertilization rate (P < 0.025) and embryo quality (P < 0.001). Cytoplasmic criteria showed no correlation in this respect. Present data indicate that ICSI of oocytes with intact well-shaped first polar bodies yields higher fertilization rates and higher quality embryos.
