Assisted Hatching (AH) is a micromanipulation technique in in vitro fertilization (IVF). By using a laser to thin, create a hole in the transparent membrane (Zona Pellucida - ZP) surrounding the embryo, help the embryo escape from the membrane, attach to the endometrium to implant and develop into a fetus.

1. What is a herniated embryo?

Around the end of day 5 after fertilization (embryo day 5), the entire mass of cells inside the blastocyst begins the process of exiting the transparent membrane (Zona Pellucida – ZP) surrounding the embryo. This process is called embryogenesis.

2. Why is it necessary to support the embryo to escape the membrane?

The blastocyst escape is a physiological process characterized by the gradual thinning of the transparent membrane surrounding the embryo and exiting through a small opening in the membrane before attaching to the endometrium for implantation and development into a fetus. .
However, in IVF, it can be caused by the impact of culture conditions, the age of the patient, the thawing process of the embryo... making the envelope of the embryo thick and hard, making it more difficult for the embryo to escape.
Assisted Hatching (AH) is a micromanipulation technique that helps embryos escape from the envelope. This technique is performed before the embryo is transferred into the uterus. Helps the embryo to easily escape from the membrane, attach to the endometrium (implantation) and develop into a fetus.
