Preimplantation genetic screening (PGS) involves screening of embryos for chromosomal abnormalities. This avoids the abnormal embryos that transferred to the uterus during IVF or ICSI.
Preimplantation genetic diagnosis (PGD) is a procedure used prior to implantation to identify specific genetic defects within embryos. This diagnosis is used to prevent genetic diseases/disorders that passes to the child.
