Laser Assisted Hatching is an advanced fertility technique used in In Vitro Fertilization (IVF) to improve the chances of embryo implantation. During IVF, embryos are created in the lab and then transferred to the uterus. For successful implantation, the embryo must break through its outer layer, known as the zona pellucida, to attach to the uterine lining. In laser hatching, a highly focused laser is used to gently thin or create a small opening in this outer layer, aiding in the embryo’s “hatching” process and improving the likelihood of successful implantation.

How Laser Hatching Works

1. Embryo Culturing: After fertilization, embryos are cultured in the lab until they reach the ideal stage for hatching (typically day 3 or day 5).
2. Laser Application: Using a specialized laser, the embryologist creates a precise opening or thins the zona pellucida without physically handling the embryo, minimizing the risk of damage.
3. Transfer to Uterus: The embryo is then transferred into the uterus, where it can attach more easily to the uterine lining.

Who Can Benefit from Laser Hatching?

Laser hatching is often recommended for:

• Women over 35 (as the zona pellucida tends to harden with age)
• Individuals with thickened zona pellucida
• Patients with prior failed IVF attempts
• Cases with poor embryo quality or frozen embryos (as freezing can toughen the embryo’s outer shell)

Benefits of Laser Hatching

• Increased Implantation Success: Helps the embryo break through its shell, improving chances of attachment.
• Precision and Safety: The laser method is quick, precise, and involves minimal embryo handling, reducing stress on the embryo.
• Promising Results for Complex Cases: Laser hatching may increase implantation success for those with challenging reproductive factors.
