What are PGS & PGD?
Preimplantation Genetic Screening (PGS) and Preimplantation Genetic Diagnosis (PGD) are both IVF procedures designed to examine your embryos for chromosomal abnormalities. An embryo biopsy is performed on day 5 or 6 to examine all 24 chromosomes- the 22 non-sex chromosomes plus the two sex chromosomes (X&Y) in time for your embryo transfer. If you are concerned about gender-based hereditary diseases or are looking for “family balancing” options, PGS and PGD can also identify the gender of the embryo. The differences between the two procedures are as follows:
Preimplantation Genetic Screening (PGS) – A screening process that ensures there are normal chromosome numbers and detects potential genetic disorders.
Preimplantation Genetic Diagnosis (PGD) – A cell is removed from an embryo to test for specific genetic conditions (i.e. cystic fibrosis) before transferring the embryo into the uterus.
Screening for healthy embryos will increase your pregnancy success rate. Both procedures are 99.9% accurate.
