PGT lets us select an embryo free of chromosomal abnormalities before the transfer. That raises implantation chances and lowers the risk of miscarriage or a child born with a genetic condition.
Aneuploidy screening: we check the embryo's chromosome count. Recommended after age 35, after failed IVF attempts, and for recurrent pregnancy loss.
Testing for single-gene disorders when a known mutation runs in the family: cystic fibrosis, SMA, hemophilia, and other hereditary conditions.
Testing for structural chromosome rearrangements in couples where one partner carries a translocation or inversion.
On day five of development, the embryologist takes a few cells from the trophectoderm (the future placenta). The embryo itself is not harmed. The embryos are vitrified while the samples go to the genetics lab. Once the results are in, the doctor transfers an embryo with a normal chromosome set.
