The oocyte and the embryo are surrounded by a protective layer called the zona pellucida (ZP). During embryo development, this ZP gradually becomes thinner to allow the embryo to hatch and implant itself in the uterine cavity.


Laser-assisted hatching

In some cases, the ZP can be abnormally thick and therefore prevent the embryo from hatching. To facilitate hatching and implantation in the uterus, we can carry out “Laser Assisted Hatching”. This technique uses a laser to thin the zona pellucida without damaging the embryo.
