Intracytoplasmic sperm injection: correlation of oocyte grade based on polar body, perivitelline space and cytoplasmic inclusions with fertilization rate and embryo quality
1 Aug 1997
Abstract excerpt
The extent to which the morphology of the oocyte at the light microscopy level is related to the results of intracytoplasmic sperm injection (ICSI) is controversial. In this study, after cumulus removal, oocytes were graded into four groups according to the status of the first polar body, size of the perivitelline space and the presence of cytoplasmic inclusions. Oocyte data from 65 consecutive patients were...
