Assisted Hatching (AH)



Assisted Hatching (AH) is a micromanipulation technique. It is able to facilitate embryo hatching and implantation, resulting in higher pregnancy rates.


Assisted Hatching (AH) involves the opening or thinning of the shell of the embryo in order to facilitate embryo hatching and subsequent implantation in the In Vitro Fertilisation process.


How does it work?


Once the egg begins its normal cellular division, it becomes a zygote and outgrows its tiny environment at an exponential rate. This pressure allows the newly forming cells to burst out of the original egg’s outer wall, which is made of a layer of proteins called the zona pellucida.


If the new embryo is unable to break out, the embryo will not be able to attach to the walls of the uterus, thus failing to achieve pregnancy. The zona pellucida can be thicker than necessary in some cases. The thicker the zona, the more difficult your embryo will have to break through it.


Our embryologists are well-trained and highly experienced in Assisted Hatching, increasing the chance of the embryo breaking out of the wall in order to attach itself to the uterine lining and thus, making embryo implantation more possible.


Our embryologist focuses on a small section of the zona pellucida. In case of embryo with difficulty hatching, they will thin the shell wall, allowing the embryo to break free.


Getting past this crucial stage allows the embryo to move on to its gestation process outside the womb until viability is confirmed. The risk of damaging the embryo during this process remains low.


Assisted Hatching (AH) in conjunction with the IVF process – along with Intracytoplasmic Sperm Injection (ICSI) – could ensure the greatest possibility of getting pregnancy.
