LAH is a quick, safe, and easy treatment that may be carried out in the lab. To decide if LAH is a good option, couples should speak with their doctor about the potential advantages and risks of the procedure.
In vitro fertilization (IVF) uses the laser assisted hatching (LAH) procedure to improve the likelihood that embryos will implant in the uterus. It entails making a tiny hole with a laser in the zona pellucida, the embryo's transparent outer layer. This is accomplished just prior to the embryo's implantation into the woman's uterus.
LAH serves to speed up hatching, the process by which the embryo leaves the zona pellucida and inserts itself in the uterine lining. The chances of successful implantation can be lowered when the zona pellucida is too thick or strong for the embryo to hatch on its own.
LAH can facilitate the embryo's implantation by making a tiny hole in the zona pellucida. Embryos with a thick zona pellucida or embryos that have previously failed to implant are the usual candidates for the surgery.
