Assisted Hatching

What is Assisted Hatching?

Assisted Hatching (AH) is the technique of thinning the shell or outer covering of an embryo. Assisted Hatching was developed from the observation that embryos with a thin zona pellucida (shell) had a higher rate of implantation during IVF. It was predicted that helping the embryo hatch out of its shell would allow for a better chance of implantation in the endometrium.

How is the Assisted hatching Technique Done?

The Assisted Hatching procedure is done in the lab. The embryos selected for transfer and for the AH are held gently in place by a glass holding pipette, while a small pipette containing an acid-type solution is used to thin or create a hole in the zona pellucida. The embryos are then rinsed to remove any excess acid solution and returned to the incubator prior to your embryo transfer procedure.

Do I need Assisted Hatching?

Before consenting for the Assisted Hatching procedure your physician will discuss whether this procedure is in your best interest. We have a list of criteria that determines if you are a good candidate for this procedure.

What are the risks of Assisted Hatching?

As with other assisted reproduction techniques, the use of Assisted Hatching does not guarantee you will become pregnant. Our technique of thinning as opposed to complete breaking of the zona pellucida is designed to reduce the exposure of the cells that make up the embryo to the acid-type solution.
