What is involved?
Assisted hatching is a laboratory procedure whereby a hole is made in the zona pellucida of a two or three-day old embryo in order to help in the ‘hatching’ process and therefore, help with the implantation of the embryo into the uterus.
Several techniques including a laser, an acid or a very sharp needle can be used to make a hole in the zona pellucida. The first assisted hatching techniques were carried out in the early 1990’s. Most IVF clinics use this procedure and many babies have been born as a result of assisted hatching. There have been no reports of an increase in abnormalities of babies born as a result of assisted hatching.
