Assisted Hatching​

Increase your chances of successful embryo implantation

Assisted Hatching

Assisted Hatching offers a gentle yet potentially transformative solution. This innovative technique helps embryos hatch from their protective shells, increasing implantation rates by up to 30%, according to the esteemed European Society of Human Reproduction and Embryology (ESHRE, 2022). Especially beneficial for women of older age age or with a history of implantation failure, Assisted Hatching can help optimise the chances of a successful pregnancy.

What Is Assisted Hatching?​

Assisted hatching is an ART procedure that facilitates the hatching or emergence of an embryo from its zona pellucida. The process involves making a small hole in the membrane using micromanipulation techniques.

What Is The Assisted Hatching Process?​

When the embryo reaches the blastocyst stage and naturally sheds the zona pellucida, assisted hatching aims to aid this process. It is particularly beneficial in cases where the membrane hardens, hindering the embryo’s ability to hatch due to factors like the age of the egg source, freezing conditions, or other causes.

The micromanipulation method employs laser technology to create a tiny opening in the zona pellucida, increasing the chances of successful hatching. The treated embryo is then placed back for further incubation or preparation for transfer.

When Is Assisted Hatching Recommended?​

Assisted hatching is recommended for:

  • Patients with a history of unsuccessful IVF treatments
  • Women with a thick zona pellucida
  • Patients undergoing frozen embryo procedures
  • Older women


Since the zona pellucida may become more rigid after freezing, assisted hatching is also beneficial before transplanting frozen-thawed embryos. The decision to proceed with assisted hatching is made based on close monitoring by experienced embryologists, and it is performed if and when necessary. 


Assisted hatching is only  recommended in specific cases, such as previous IVF failures, thick zona pellucida, and frozen embryo procedures.

Laser technology is used in the micromanipulation process to create a small opening in the zona pellucida.

Yes, assisted hatching can be performed with frozen-thawed embryos. In fact, it is often recommended in such cases to improve the chances of successful implantation.

The assisted hatching procedure is relatively quick and typically takes only a few minutes. The entire IVF process, including assisted hatching, involves careful planning and coordination, and your fertility team will provide a timeline for each step.

Assisted hatching does not require medication. It is a procedure performed on the embryo before transfer, involving the creation of a small opening in the zona pellucida, the outer layer of the embryo. This facilitates easier implantation.
