Pre-Implantation Genetic Diagnosis and Screening (PGD and PGS)

Some patients have a family history of inheriting congenital genetic disorders with chromosomal abnormalities such as cystic fibrosis. Genetic testing of the embryos before implantation is a powerful technology for patients concerned about having a child with such an illness and is available only to those who are in vitro fertilization. This technique is significant as it allows only the embryos with a proper genetic arrangement to be transferred into the uterus. PGD/PGS may be recommended in additional circumstances such as recurrent miscarriages, more than three failed IVF procedures, and the fourth decade of a woman’s life when her own egg cycle is followed.

PGD and PGS are the techniques for all genetic testing. An embryologist performs an Embryo Biopsy and supplies the genetic lab with some suitable embryonic cells for examination. During the blastocyst stage, there are two types of biopsy techniques depending on the day of the embryo growth: cleavage-stage/day three biopsy and trophectoderm (TE) / day five or day six biopsy. Before your fertility treatment, you can discuss and decide on the above by meeting with our IVF experts, embryologists, and genetic lab professionals.
