Laser Assisted Hatching (LAH) is a cutting-edge fertility treatment that can increase the chances of successful embryo implantation. The procedure involves using a laser beam to create a small hole in the outer layer (zona pellucida) of the embryo, which allows the developing cells to hatch out and increase their chances of implanting in the uterine lining.

LAH is typically used in conjunction with in-vitro fertilization (IVF) and is considered a form of assisted reproductive technology (ART). It is most commonly used in cases where the zona pellucida is thicker than normal, which can make it more difficult for the embryo to hatch and implant.

The procedure is performed on the day of fertilization, and the embryos are then transferred to the uterus two or three days later. The procedure is relatively quick and non-invasive, and has been shown to increase the chances of successful pregnancy in some cases.
