Assisted zona hatching

Assisted zona hatching is a procedure of assisted reproductive technology, mainly used in IVF, which assists zona hatching. To achieve this a small hole is made in the zona pellucida (mechanically, chemically or by laser) to facilitate hatching.[1] Zona hatching is where the blastocyst gets rid of the surrounding zona pellucida to be able to implant in the uterus.
