Trophectoderm biopsy

The collection of cells from the outer layer of an embryo at the blastocyst stage; the cells are genetically tested to ensure that the embryo is healthy. This method is used in preimplantation genetic testing (PGT), which helps detect chromosomal abnormalities or hereditary disorders. This analysis allows a genetically healthy embryo to be selected, increasing the chances of a successful pregnancy and reducing the risk of miscarriage.
