Laser Assisted Hatching LAH

Laser assisted hatching (LAH) is a procedure where a laser beam is used to make a small hole in the outer layer of the embryo. This helps the embryo to hatch out and prepare to implant in the woman’s uterus. While most patients choose to use LAH on their embryos prior to an embryo transfer, this procedure is optional and some patients decide not to use LAH at all.
