PGS is a genetic study of the embryo produced during IVF treatment and can help you have a healthy baby. The PGS test:
PGS is especially recommended for:
Multiple pregnancies after an IVF treatment were usual, as clinicians transferred two or more embryos in an attempt to maximize the chances of implantation.
However, multiple pregnancy has increased risks for the mother and the babies:
Twin pregnancy is associated with more pregnancy complications and poorer pregnancy outcome than singleton pregnancy.
The development of the IVF techniques and recent studies demonstrate no statistical difference in pregnancy achieved by Single Embryo Transfer and a reduction in multiple gestations.More info
