Oocyte Denuding

The cumulus and corona cells are removed prior to any micromanipulation procedure by exposure of the cumulus–oocyte complexes to a combined enzymatic and mechanical treatment that causes the breakdown of the hyaluronan-based matrix surrounding COCs and disperses the cumulus cells from oocytes. After denudation of cumulus and corona layers, a noninvasive analysis of different oocyte quality biomarkers can be provided in order to select the most developmentally competent oocytes to inseminate. In this chapter, indications about the equipment, procedure, and timing to perform oocyte denudation that should be adopted in order to minimize any potential damage to oocyte viability will be reviewed.
