Laser Assisted Hatching
A lab technique in IVF where a laser helps the embryo hatch, improving implantation chances.

Laser Assisted Hatching
Laser Assisted Hatching is a laboratory technique used during in vitro fertilisation (IVF) to improve the chances of embryo implantation in the uterus.
In this procedure, a laser is used to gently thin or create a small opening in the outer layer of the embryo, known as the zona pellucida. This outer shell normally protects the embryo in the early stages of development.
For a successful pregnancy to occur, the embryo must “hatch” from the zona pellucida before it can attach to the lining of the uterus (endometrium). Assisted hatching helps make this process easier.
Why Laser Assisted Hatching Is Performed
In some cases, the zona pellucida may become thicker or harder, which can make it difficult for the embryo to hatch naturally. This may reduce the chances of implantation.
Laser assisted hatching is performed to:
Help the embryo hatch from the outer shell
Improve the likelihood of implantation
Increase the chances of pregnancy during IVF
Who May Benefit from Laser Assisted Hatching?
This technique may be recommended in situations such as:
Women over 38 years of age
Previous unsuccessful IVF cycles
Embryos with a thicker zona pellucida
Poor embryo implantation in earlier treatments
Procedure
The procedure is carried out in a laboratory before the embryo transfer step of IVF.
The embryo is placed under a microscope.
A precise laser beam is used to thin or create a small opening in the zona pellucida.
The embryo is then transferred into the uterus as part of the IVF process.
Advantages
May improve embryo implantation
Can help embryos hatch more easily
A precise and controlled laboratory procedure
Laser assisted hatching is considered an additional supportive technique in assisted reproductive treatments, particularly for patients who have experienced difficulties with embryo implantation.
