Embryo biopsy is a very delicate process and requires great skill on the part of the professionals. When the embryo reaches day 5 of development, it reaches the blastocyst stage. At this point it is possible to distinguish three parts of the blastocyst: the blastocele, the inner cell mass and the trophectoderm.
When a blastocyst stage embryo biopsy is performed for preimplantation genetic diagnosis, the zona pellucida of the embryo is incised with a laser and cells are aspirated from the trophoectoderm. These cells are carefully introduced into a tube and will be genetically analyzed.
