What Exactly Is Assisted Hatching?
Once the embryo has been transferred to the uterus, it should hatch from its protective layering and stick to the uterine lining for a successful implantation. Assisted hatching is recommended only in specific cases, where the outer protective layer or zona pellucida (layer of protein) is thicker. This procedure is carried out on the embryo that is unable to break through its protective layer zona pellucida and is unable to successfully attach itself to the uterine lining. Assisted hatching is a delicate and extremely skillful process by which the outer protective laye (zona pellicuda) is pierced in order to aid hatching of the embryo. Assisted hatching, performed by skilled and experienced micromanipulators, has displayed high implantation success rates, even in cases where the woman is aged between 35 to 39 years.
