Assisted Hatching

By means of assisted hatching, an opening is made in the zona pellucida immediately before the embryo transfer to make it easier for the embryo to leave the zona pellucida and thus to allow it to implant in the endometrium.

This procedure is recommended for patients aged 38 years and older, for the transfer of embryos resulting from cryopreserved oocytes and for couples who have already had 2-3 IVF cycles with good transfer results but no pregnancy. It is assumed that in these cases, a hardening or thickening of the zona pellucida is the cause of the lack of implantation of the transferred embryos.
