Laser Assisted Hatching

Laser Assisted Hatching (LAH) is a technique used in in vitro fertilization (IVF) to help embryos implant successfully in the uterus. During the IVF process, embryos are cultured in a lab after being fertilized outside the body. Once the embryos reach a certain developmental stage, they need to "hatch" from their protective outer shell, called the zona pellucida, in order to implant into the lining of the uterus and grow into a pregnancy.

However, in some cases, the zona pellucida may be too thick or difficult for the embryo to break through naturally. This can prevent successful implantation. Laser Assisted Hatching involves using a fine laser to make a small opening in the zona pellucida, allowing the embryo to hatch more easily and improving its chances of implantation.

LAH is typically recommended for women undergoing IVF with poor embryo quality, advanced maternal age, or recurrent IVF failure. It can also be helpful for embryos with thick zona pellucida, ensuring better chances of success in embryo transfer.

The development of LAH is a part of the ongoing efforts to improve IVF success rates, especially in cases where traditional methods of embryo transfer have failed. This procedure, though relatively simple, requires advanced technology and precise technique to minimize risks and optimize results.

Laser Assisted Hatching is primarily used in situations where an embryo may have difficulty hatching naturally. Below are the causes and risk factors that may lead to the need for LAH:

Thick Zona Pellucida:

The zona pellucida is a protective membrane surrounding the embryo. In some embryos, especially those from women of advanced maternal age, this membrane becomes thicker and more rigid. A thicker zona pellucida can make it difficult for the embryo to hatch and implant in the uterus.

Advanced Maternal Age:
