Introduction
Laser-assisted hatching (LAH) is a groundbreaking technique used in assisted reproductive technology (ART) to improve the chances of successful embryo implantation during in vitro fertilization (IVF). This innovative procedure involves the precise application of laser energy to create a small opening in the outer layer of the embryo, known as the zona pellucida. By facilitating the embryo’s hatching process, LAH aims to increase the likelihood of successful implantation in the uterine lining, ultimately leading to a higher rate of pregnancy success.
How Does Laser-Assisted Hatching Work?
During natural conception, the embryo must break through its protective shell, the zona pellucida, in order to implant into the uterus. However, in some cases, this shell may be too thick or rigid, hindering the embryo’s ability to hatch and implant. Laser-assisted hatching addresses this challenge by precisely thinning or creating a small opening in the zona pellucida using a specialized laser. This delicate procedure is performed just before embryo transfer, allowing the embryo to emerge more easily and increasing the chances of successful implantation.
