PGD: PRE-IMPLANTATION GENETIC DIAGNOSIS is an optional procedure that may be performed during an in-vitro fertilization (IVF) cycle, and makes use of genetic testing to screen embryos for genetic or chromosomal abnormalities. Only embryos found to be free of the tested condition are selected to be transferred into the woman’s uterus.
PGD can increase the chance that pregnancy occurs, dramatically reduce the risk of early miscarriage, and lower the odds of birth defects.
