Laser Assisted Hatching

Laser-Assisted Hatching (LAH) is an advanced technique used in IVF to help embryos implant successfully in the uterus. During IVF, embryos develop a protective outer layer called the zona pellucida. For implantation, this layer must hatch. Sometimes, the zona pellucida hardens, making it difficult for the embryo to hatch and implant. LAH uses a precise laser to create a small opening in this layer, aiding implantation and increasing the chances of pregnancy.

When is Laser-Assisted Hatching Recommended?

  • LAH can be particularly beneficial for:

  •  

  • Women over 35 years of age.

  • Patients with a history of failed IVF cycles.

  • Those with embryos having a thickened zona pellucida.

  • Patients with poor-quality embryos.

  • Women undergoing embryo transfer with frozen-thawed embryos.

How is Laser-Assisted Hatching Performed?

  • The LAH procedure involves the following steps:

  •  

  • Embryo Development: Embryos are cultured in the lab for 3 to 5 days.

  • Laser Application: A specialized laser creates a small opening in the zona pellucida. This step is quick, taking only a few seconds, and is done with high precision to ensure the embryo's safety.

  • Embryo Transfer: The embryo is then transferred to the uterus for implantation.

Benefits of Laser-Assisted Hatching

  • Improved Implantation Rates: LAH helps embryos hatch and implant more easily, increasing the chances of pregnancy.

  • Safety and Precision: The laser technology allows for controlled and accurate hatching without manual handling, reducing the risk of damage to the embryo.

  • Enhanced Success with Frozen Embryos: Frozen-thawed embryos with a hardened zona pellucida benefit greatly from LAH, as it facilitates their hatching and implantation.

Risks of Laser-Assisted Hatching

  • While LAH is generally safe, it carries some risks similar to other IVF procedures:

  •  

  • Embryo Damage: There is a slight risk that the embryo might be injured during the procedure, potentially affecting implantation.

  • Failure to Hatch: In some cases, even after LAH, the embryo might not hatch completely, leading to implantation failure.

  • Multiple Pregnancies: LAH can increase the risk of multiple pregnancies, which are associated with higher medical risks.
