ACTIVE COMPARATOR

Mechanical Assisted Hatching - artificial rupture of the embryo external glycoprotein layer (Zona Pellucida) before embryo transfer.

Device: Mechanical Assisted Hatching

Interventions

The technique of assisted hatching using partial zona pellucida dissection to create an artificial opening of the zona pellucida of early cleaved embryos. While the embryo is stabilized by a holding pipette of micromanipulator, the zona pellucida is pierced with a microneedle that is pushed tangentially through the space between the zona pellucida and blastomeres until it pierces through the zona pellucida again.

Assisted Hatching

Eligibility Criteria
