Assisted hatching (AH) is a micromanipulation procedure in which a laser beam (the most gentle method of AH) creates an opening in the protective envelope of an embryo called the zona pellucida.
This envelope surrounds the egg and then the embryo until time before the nidation, ie its nesting in the uterus. AH will thus help the so-called “pull out” of the embryo from the envelope before it happens spontaneously. This is especially useful in the case of a planned embryo cell biopsy for PGT.
Furthermore, we perform AH automatically on embryos that have a significantly strong pellucid zone, which could prevent their implantation in the uterus or on all non-hatching embryos after thawing before KET.
