What is Laser Assisted Hatching (LAH)?
Laser-assisted hatching (LAH) is a technique used in assisted reproductive technology (ART) during in vitro fertilization (IVF) to help improve the chances of embryo implantation in the uterine lining. The procedure involves creating a small opening or thinning the outer shell of an embryo, known as the zona pellucida, to facilitate the embryo’s ability to “hatch” from this protective layer and implant in the uterus.
BENEFITS OF LASER ASSISTED HATCHING
The rationale behind laser-assisted hatching is to increase the likelihood of successful embryo implantation by making it easier for the embryo to escape from the zona pellucida and attach to the uterine lining. It is believed that this technique may be particularly beneficial in certain cases, such as:
- Advanced Maternal Age: Women of advanced maternal age (typically over 35) may have eggs with thicker or harder zona pellucida, which can hinder the embryo’s ability to hatch and implant.
- Previous IVF Failures: For individuals who have had previous IVF cycles with failed implantation, laser-assisted hatching may be considered to improve the chances of success in subsequent attempts.
- Abnormal Embryo Development: In some cases, embryos may have an unusually thick or tough zona pellucida, which could impede hatching.
While laser-assisted hatching can be beneficial in specific situations, it is not without risks and may not be necessary for all IVF patients. Discussing the potential benefits and risks with a qualified fertility specialist is important for making an informed decision about whether to include this technique in an IVF treatment plan.
