Complete Guide Laser Assisted Hatching
What is LAser Assisted Hatching?
Laser assisted hatching is method to create a gap in an embryo’s shell before placing the embryo. This technique allows to increase to potential of hatching the shell subsequent to the development of a blastocyst.
Why use Laser Assisted Hatching?
It is because lasers are often used in the IVF lab experiments to perform the trophectoderm biopsy for hatching procedures. The process is more secured and success rates are higher than conventional methods.
Methods used for IVF hatching
In the present tie laser hatching has become widely popular in IVF treatments and is the best technique for microchanges of embryos. It should be performed by specialists to prevent cell damage.
- Using acid Tyrode’s solution
- Mechanically for example by partial zona dissection
- Laser hatching
Who can get the benefits of Laser Hatching?
- Patients with age above 37 years old
- High Day 3 follicle stimulating hormone
- Dense or anomalous egg shell
- Wide division in embryos
- Double times or higher frequency of failed IVF earlier
Laser Assisted hatching is performed?
Laser is focused on a region where it will be fired. The invisible beam shows the effect without showing itself.
Energy is released by laser on the shell that results into shell’s vaporization or dissolution. As heat is developed, it is used carefully to prevent excessive heating of the shell. Moreover, power settings, procedure and target size also describe the specific technique that needs to be followed.
Typical procedure steps are:
- On the 3rd day of embryo development, micro laser is used to create a hole in the external layer of the embryo.
- Embryo is then placed in the womb again where it can hatch from its external layers and connect to the uterine lining
- Assisted hatching creates a hole in the security layers of embryo, so mother gets antibiotics to avoid infection.
Success rate of laser assisted hatching
Lasers are commonly used to conduct trophectoderm biopsy. Hatching by laser is more rapid and convenient as compare to acid procedure. It is also found that assisted hatching significantly increases the success rates in IVF unlike to standard IVF.
Pros
- Higher pregnancy success for couples whose embryos are in risky situation
- Women above 38 years old become pregnant
- Increases hope to become parents
Cons
- Risk of embryo damage
- More chances of having Siamese twins
- Risk of abnormality in kid
