Assisted hatching is indicated in some particular cases. For instance, in cases of embryos with a thickened zona pellucida or with an abnormal colour of the zona pellucida.
Assisted hatching is a technique used to make it easier for the embryo to break through its protein-rich coat, the zona pellucida (ZP). The aim is to enable implantation and, therefore, increase the chances for pregnancy in some particular cases.
