Laser Assisted Hatching

Overview of Laser Assisted Hatching

A covering layer, or ‘shell’ surrounds embryos or blastocysts called the Zona Pellucida (ZP). The zona has an important role in fertilisation as it allows only one sperm to penetrate the zona and enter the egg to achieve fertilisation. It also acts to prevent premature implantation in the Fallopian tube and may help prevent the early embryo from being attacked by cells of the immune system.

The embryos have to “hatch” or break out of the zona in order to embed into the endometrium lining the uterine cavity. This occurs about four to five days after embryo transfer when the embryo is at the blastocyst stage. Naturally this takes place by expanding/contracting of the zona until it distorts, allowing the blastocyst to “hatch”.

Methods of Assisted Hatching

Chemical

This involves chemicals (acid tyrodes) used to produce a weakened area of the zona. The chemical is applied through a microtool, manipulated by an embryologist.

Laser

The zona is drilled by the microlaser system called Fertilase. It creates a clean-cut precise incision in the zona.

Who is Suitable for Laser Assisted Hatching ?

Those patients who have IVF or ICSI who are over 37 years Patients having FER Patients who have had a previous failed IVF or ICSI treatment cycle Patients undergoing IVF/ICSI for the first time, who are considered poor esponders because they have required a high dose of gonadotrophins for poor varian response Patients who in an earlier IVF cycle have had a low fertilisation rate, for example, less than one third of the embryos achieving fertilsation Patients with three or fewer embryos Patients who request laser assisted hatching and are fully informed of its use and function.

Laser assisted hatching – a photo essay

It’s a sad fact that IVF technology today is still not perfect. Only one of ten embryos we transfer in the uterus implants successfully in the endometrium to become a baby. Why is the embryo implantation rate only 10 ? Some doctors believe this is because the surrounding shell of the embryo (called the zona pellucida) hardens when it is cultured in the laboratory.
