Embryologists can also check for chromosomal abnormalities. The embryo is biopsied. A biopsy can be done on day 3 or day 5 of embryonic development.
Reduce the risk of damage by removing a single cell from the trophectoderm on day 3 or by removing multiple cells on day 5 to reduce the risk of damage.\n\nSecondary culture\nIn some cases, secondary culture is required. The outer membrane of the embryo, called the zona pellucida, is thinned with a laser to allow implantation.
