Assisted Hatching

Before implantation, the embryo must hatch from its shell to attach to the womb. In some cases, the shell is unusually hard, thus reducing the chance of implantation.

Assisted hatching is, therefore, a procedure in which the outer layer (zona pellucida) of the selected embryo is either thinned or opened using laser to facilitate hatching.

Indications for Assisted Hatching

  • Women with elevated basal FSH & poor prognosis
  • Women who have repeated unsuccessful attempts
  • Women for frozen thawed embryo transfer, as it is believed that the freezing process may harden the embryo shell
  • Embryos with thick zona
