What is Laser-Assisted Hatching?
Laser-Assisted Hatching (LAH) is a specialized technique used during in vitro fertilization (IVF) to improve the chances of embryo implantation in the uterus. The procedure involves using a precise laser to create a small opening in the outer layer of the embryo, known as the zona pellucida. This outer layer can sometimes be too thick or hard, making it difficult for the embryo to “hatch” and implant into the uterine lining. By creating a small gap in the zona pellucida, Laser-Assisted Hatching helps facilitate the natural hatching process, enhancing the embryo’s ability to implant and establish a pregnancy.
This technique is typically used for patients who have experienced multiple failed IVF cycles, women of advanced maternal age, or when embryos show signs of having a thickened outer layer. Laser-Assisted Hatching is a safe and controlled method to support successful embryo implantation.

When is Laser-Assisted Hatching Recommended?
Laser-Assisted Hatching is not routinely performed for every IVF cycle but is particularly recommended in specific cases where hatching may be impaired or challenging. Common situations where LAH may be beneficial include:
• Women of Advanced Maternal Age: As women age, the zona pellucida of their embryos can become harder and thicker, making it difficult for the embryo to naturally hatch and implant.
• Previous Failed IVF Cycles: Couples who have had multiple unsuccessful IVF attempts may benefit from LAH, especially if poor embryo implantation is suspected to be the issue.
• Poor Embryo Quality: Embryos with a thicker or harder zona pellucida may have difficulty hatching, and LAH can improve their chances of successful implantation.
• Frozen Embryo Transfers: Embryos that have been frozen and thawed for transfer may have a tougher outer shell due to the freezing process. LAH can assist these embryos in hatching more easily.
• Embryos After Genetic Testing: In cases where an embryo biopsy has been performed for PGS (Preimplantation Genetic Screening) or PGD (Preimplantation Genetic Diagnosis), LAH can be used to help the embryo hatch after undergoing testing.
What are the Steps Involved in Laser-Assisted Hatching?
IVF and Embryo Development
Before Laser-Assisted Hatching can be performed, the couple undergoes the standard IVF process. This includes ovarian stimulation, egg retrieval, fertilization of the eggs with sperm, and embryo development in the laboratory. The embryos are allowed to grow until they reach the blastocyst stage, when they are ready for implantation.
Laser-Assisted Hatching Procedure
Once the embryos have developed to the appropriate stage, an embryologist uses a specialized laser system to create a small hole or thinning in the zona pellucida. The laser is precisely controlled to ensure that only the outer layer is affected and that the inner cells of the embryo remain unharmed. This opening facilitates the hatching process by allowing the embryo to break free from its outer shell and attach to the uterine lining.
Embryo Transfer
After the LAH procedure is complete, the embryo is ready for transfer into the woman’s uterus. The embryo transfer is a simple, non-invasive procedure that does not require anesthesia and is typically performed in a few minutes. Once the embryo is placed in the uterus, it can implant and begin to develop into a pregnancy.
Post-Procedure Monitoring
Following the embryo transfer, the patient will be closely monitored to ensure optimal conditions for implantation. A pregnancy test is usually performed 10 to 12 days after the embryo transfer to determine if the procedure was successful. If the test is positive, the pregnancy is monitored with regular check-ups and ultrasounds.
What are the Benefits of Laser-Assisted Hatching?
• Improved Implantation Rates: By creating an opening in the zona pellucida, LAH helps embryos hatch more easily and improves their ability to implant in the uterine lining.
• Higher Pregnancy Success: LAH can increase the chances of a successful pregnancy, particularly in cases where thickened zona pellucida is preventing natural hatching.
• Safe and Precise Technique: The use of a laser allows for controlled and precise manipulation of the embryo’s outer shell without causing damage to the embryo itself.
• Minimally Invasive: LAH is a non-invasive procedure that involves no physical contact with the embryo, reducing the risk of injury or harm.
• Helps with Frozen Embryo Transfers: LAH can be especially beneficial for embryos that have been frozen and thawed, as freezing can harden the zona pellucida.
Is Laser-Assisted Hatching Safe? Laser-Assisted Hatching is considered a safe and effective procedure when performed by experienced embryologists using advanced laser technology. The laser used in LAH is highly accurate and allows for precise control, minimizing the risk of harm to the embryo. Studies have shown that LAH can increase the chances of successful implantation and pregnancy in certain cases, particularly for women of advanced maternal age or those who have experienced failed IVF cycles.
However, like all fertility treatments, the decision to use Laser-Assisted Hatching should be made in consultation with your fertility specialist, who will evaluate your individual situation and recommend the best approach for your IVF cycle.
