What is laser-assisted hatching in IVF, and how does it work?

Laser-assisted hatching in IVF is a technique used to help the embryo hatch out of its protective outer shell, which is necessary for implantation into the uterus. A laser is used to create a small hole in the zona pellucida, making it easier for the embryo to hatch and implant. This technique can improve the chances of successful implantation, especially in cases where the zona pellucida is thick or hard.
