Assisted hatching
This is a laboratory technique in which highly specialized biologists, shortly before embryo transfer, create with the use of acidified solution a small opening in the outer shell (zona pellucida) of the embryo. According to this theory, the opening makes the embryo softer and better implantable in the endometrium.
Data from international literature suggest that assisted hatching can only help and increase success rates in selected cases, such as multiple implantation failures, in cases where the woman is over 40 years old and in cases where the embryo’s zona pellucida appears thickened in the microscope.
Obviously, this benefit cannot be seen in all in vitro fertilization programs.
