Prognostic value of first polar body morphology on fertilization rate and embryo quality in intracytoplasmic sperm injection

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