Laser assisted hatching
Laser assisted hatching is a technique done in the laboratory with the use of laser, where the zona is drilled and a gap is made in the zona (zona is the shell of the embryo).
This is done before embryo transfer, the idea is that a small part of the trophectoderm starts protruding out so as to help the embryo attach to the endometrial tissue
Hatching can be done in 3 ways :
1. With acid tyrode’s solution
2. Mechanically dissecting a small portion of the zona
3. Using laser
Some studies show that laser assisted hatching does improve the success rate of IVF by improving the implantation rate. Some studies also say that laser assisted hatching also improves the implantation rate of frozen embryos
