Laser Assisted Hatching (LAH)

Laser Assisted Hatching (LAH)

The outer shell of the egg is called the Zona Pellucida. Hatching is the process in which the embryo herniates out of the outer shell of the egg. Failure of the embryo to hatch may be one of the factors associated with implantation failure.

Assisted Hatching is a procedure in which the zona pellucida (outer shell of the egg) is partially opened to help facilitate hatching out process of the embryo and thus implantation and pregnancy.

What is Laser Assisted Hatching (LAH)?
