Compaction and Surface Polarity in the Human Embryo in Vitro

1 Jul 1996

Abstract excerpt

The surface morphology of the human ovum fertilized and cultured in vitro to the morula stage was studied by scanning electron microscopy with the specific aim of investigating embryo compaction and polarity. Unfertilized oocytes examined one day after attempted insemination (Day 0) were evenly and densely covered by long microvilli. The length and density of microvilli appeared to decrease in fertilized...
