Preimplantation Genetic Screening, PGS
PGS is a genetic test designed to examine embryos for chromosomal abnormalities. Embryos are biopsied at the blastocyst stage and all the chromosomes are examined. Embryos with too many or too few chromosomes, a condition called aneuploidy, often result in unsuccessful IVF or early pregnancy loss. By only placing embryos with the correct number of chromosomes (euploid embryos) in the uterus, PGS aims to improve implantation and pregnancy rates in people having IVF.
Who might be recommended to have PGS?
- Women aged over 34
- Several miscarriages
- Repeated IVF failure
- Serious causes of male infertility
- Carrier of inherited genetic diseases ad chromosomal translocations
