BIOMATERNITY Fertility and IVF Specialsts-LASER ASSISTED HATCHING

Laser Assisted Hatching

Before an embryo can attach to the wall of the womb, it has to break out or ‘hatch’ from its outer layer, the zona pellucida. It has been suggested that, by Laser Assisted Hatching, making a hole in, or thinning, this outer layer may help embryos to hatch, which may increase the chances of pregnancy.

Assisted hatching is done while the embryo is in the laboratory.

Before being transferred back to the womb a hole is made in the outer layer of the embryo or it is thinned, using acid, laser or mechanical methods.

A typical procedure is:

Step 1

On day three of embryo development, the embryologist uses either weak acid in a fine glass pipette, a microlaser or a microtool to thin or cut a hole in the outer layer of the embryo.

Step 2

If weak acid was used, the embryo is washed to prevent further damage.

Step 3

Because assisted hatching thins or makes a hole in the protective outer layer around the embryo, the woman may be given antibiotics to prevent infection.

It is shown that the use of assisted hatching results in higher pregnancy rates in selected cases. For example, it has been noted that in the older woman the zona pellucida around the embryo can appear to be thickened. The making of a ‘weak point’ in the zona may help implantation.

Female fertility diminishes with age, so if you are using your own eggs, on average, the younger you are, the higher your chances of success.

Risks of Assisted Hatching

Current research suggests that this treatment is no more likely to cause an abnormality to the baby than IVF without assisted hatching. As it is only the outer layer that is affected by this procedure, the embryo should remain unharmed.

There is always some risk of damage with any procedure of this type.

If you have more than one embryo transferred, this may increase the risk of multiple births.
