Laser Assisted Hatching (LAH) is an advanced IVF technique used to improve implantation rates. Using a precision laser, a tiny opening is made in the outer shell of the embryo (zona pellucida), allowing the embryo to hatch and attach more effectively to the uterine lining.
In some cases, embryos fail to implant naturally because they cannot hatch from their outer layer (zona pellucida). LAH helps overcome this challenge by using a safe and precise laser beam to create a small opening in the zona. This improves the embryo’s chances of successful implantation in the uterus.
Earlier, fixed lasers were used, but modern techniques employ advanced movable (navi) lasers, ensuring greater accuracy and safety. LAH is also valuable during procedures like blastomere or ectoderm biopsy in genetic testing.
