PGT-A (Preimplantation Genetic
Testing for Aneuploidy)
The selection of ‘normal or Euploid’ embryo(s)
following genetic testing before a transfer procedure
FAQ
Q: Who should consider PGT-A genetic screening?
A: PGT-A genetic screening is typically recommended for women over 38, those with repeated miscarriages, or previous implantation failures, as it increases the likelihood of transferring a chromosomally normal embryo.
Q: How does PGT-A embryo testing work?
A: During PGT-A embryo testing, embryos are cultured to the blastocyst stage (5–6 days), and a small biopsy of cells is taken. These cells are screened using Next Generation Sequencing (NGS) to identify euploid embryos, which are then frozen until a Frozen Embryo Transfer.
Q: What are the risks of PGT-A IVF?
A: Risks are similar to standard IVF, including multiple births, miscarriage, or ectopic pregnancy. Additionally, some embryos may be abnormal or fail to produce a result. Approximately 90% of biopsied embryos yield results, classified as euploid or aneuploid.
