What is Laser-Assisted Hatching (LAH)?

Laser-Assisted Hatching (LAH) is an advanced fertility technique used in conjunction with In Vitro Fertilization (IVF) to enhance embryo implantation. In this process, a precision laser creates a microscopic opening in the outer shell of the embryo (called the zona pellucida), helping the embryo “hatch” and attach more easily to the uterine lining.

This delicate step can make a significant difference for certain patients — especially those who have experienced previous IVF failures or have embryos with thicker outer shells. By facilitating natural hatching, LAH increases the likelihood of a successful pregnancy.

How Does Laser-Assisted Hatching Work?

The LAH procedure is performed in the embryology lab using cutting-edge laser technology. The process is quick, safe, and does not harm the embryo. Here’s how it works:

• After fertilization, embryos are cultured in the lab for about 3–5 days.
• The embryologist uses a specialized laser to make a tiny opening in the embryo’s outer shell (zona pellucida).
• This opening allows the embryo to expand and implant more easily into the uterine wall once transferred.
• The process is non-contact — the laser does not touch the embryo, ensuring accuracy and safety.

Who Can Benefit from Laser-Assisted Hatching?

LAH is particularly recommended for patients who face specific fertility challenges, including:

• Women above the age of 35, where embryos often have a harder outer layer
• Couples who have experienced multiple failed IVF or ICSI attempts
• Cases involving frozen and thawed embryos (as freezing can harden the zona pellucida)
• Patients with poor embryo quality or slow embryo development
• Women with high FSH levels or low ovarian reserve

Advantages of Laser-Assisted Hatching

• Increases implantation and pregnancy rates in selected cases
• Safe, precise, and controlled process using non-contact laser technology
• Improves chances of success in women with advanced maternal age
• Beneficial for embryos that have difficulty hatching naturally
• Quick, painless, and performed before embryo transfer

Precautions and Aftercare

Since LAH is performed in the laboratory, no special precautions are required from the patient during the procedure. However, after embryo transfer, it is important to follow the fertility specialist’s advice:

• Take prescribed hormonal medications as directed
• Rest and avoid strenuous physical activity for a few days after transfer
• Eat a balanced diet and stay hydrated
• Follow up for pregnancy testing 12–14 days after embryo transfer
