Implantation occurs by the embryo splitting open to release the cells inside. These cells then stick or adhere to the wall of the uterus. Occasionally there is concern that the transferred embryo does not open up to release the cells inside. If there is any suspicion that this may be the case, on day 3 of incubation, the embryologist will perforate the outer covering of the embryo making a hole using a low temperature laser. By creating this weak point in the embryo covering, the cells inside should be released to increase the probability of implantation.
