Laser-assisted hatching is regarded as the best option for couples pursuing IVF therapy but persistently accepting failure. The situation occurs more frequently in women over 37 because they produce a thicker zone pellucid that stops the eggs from hatching. Hatching with laser assistance enhances the potential of boosting pregnancy odds. The embryo is examined by the embryologist using a number of techniques. Once an embryo is formed, zona pellucid, a tough outer layer of cells, surrounds it. The embryo must next escape its shell and deposit itself in the uterus in order to become pregnant. The general idea behind laser-assisted hatching is to help the embryo emerge from the shell by making a tiny fracture rather than a larger opening.
Types of Laser Assisted Hatching
There are a few different methods and types laser assisted hatching. The majority of clients believe that a minor crack or tear in the zona pellucid is required for the aided hatching process. Types of laser assisted hatching are:
Mechanical hatching:
In mechanical hatching, the embryologist stabilizes the embryo using a pipette. In order to penetrate the zona pellucid and reach the inside of the shell, a microneedle is required. Rub the region between the puncture until a little rip appears. The size of the opening is difficult to manage with this procedure, hence embryologists do not often advise mechanical hatching.
Mechanical expansion of the shell:
In this, hydrostatic pressure is injected rather than the zone pellucida being broken. The outer shell naturally expands during this process. The embryo may be harmed by hydrostatic pressure.
Chemical Hatching:
The zona pellucid is treated with Tyrode's acid until the shell is broken. The embryo is quickly cleansed to prevent needless acid exposure.
Laser Assisted Hatching:
Under a microscope, a powerful light beam is used in the laser-assisted hatching process to crack open the embryo's shell. Three days after fertilization (using an IVF or intracytoplasmic sperm injection (ICSI) cycle), the laser hatching procedure is carried out. The entire laser hatching procedure just takes a few minutes, and the embryo is unaffected. After IVF's laser hatching process is complete, the embryo is then returned to the female uterus, where it will continue to develop.
Who is Laser Assisted Hatching for?
The laser-assisted hatching treatment is available to people who have failed at IVF. The greatest prospects for laser hatching are females who want to undergo frozen embryo transfer with laser-assisted hatching.
A successful hatching of an embryo is hampered by a number of circumstances. Even two or three days after embryo transfer, the zona pellucid is frequently tougher in women who are 37 years of age or older. When using laser-assisted hatching to attempt to hatch new embryos, the procedure becomes dangerous and complicated. IVF specialists usually recommend laser assisted hatching to:
Benefits of Using Laser Assisted Hatching
Evidence suggests that aided hatching might increase clinical pregnancy rates in individuals who:
Although it was thought that aided hatching using frozen embryo transfer cycles could be worthwhile to explore, this may not be the case. In fact, aided hatching in a cycle of frozen embryos may marginally reduce the likelihood of live delivery.
