Assisted Hatching

Assisted Hatching

Assisted Hatching is another modern technique that can increase the chances of fertility in an IVF treatment. In order for the successful implantation of the embryo in the uterus it has to hatch out of its zonal pellucida which is a layer of protein surrounding the embryo. Now it has been found that embryos with thin shells can easily attach to the uterine lining. . So when there has been failed IVF it be could because of the thick shell that prevents the eggs from attaching. In such cases hatching can be helpful as it creates a small hole on the outer shell of the embryo. This is done carefully only on the outer shell and without harming the embryo inside. Once this is completed the embryo will easily be able to come out of its zonal pellucida and attach to the uterus.

When is this recommended?
