Assisted hatching involves making a hole in the shell (zona) surrounding the embryo. It has suggested that this may improve the chance of the embryo attaching to the womb so that pregnancy can begin. Some studies have shown that there was no evidence of an increase in live birth rate with assisted hatching although it improves the chances of pregnancy in women where IVF has been repeatedly unsuccessful.
