Embryo Genetic Testing – PGD / PGS / CCS

PGS (CCS) is currently the most common laboratory technique used for testing pre-implantation embryos for chromosomal aberrations in patients undergoing in vitro fertilization (IVF). It allows the embryologist to look for chromosomal or genetic problems with the embryo. Chromosomal problems include an abnormal number of chromosomes, loss of portions of a chromosome, or attachment of one piece of a chromosome to another chromosome. Genetic problems include inherited conditions that run in families.

PGD, PGS (CCS), and gender selection all refer to various testing technique. However, irrespective of the type of testing, all of them require embryo biopsy.

Embryo biopsy is a rather sophisticated and delicate procedure where a trained embryologist removes one or more cells from the pre-implantation embryo using microscopic tools, micromanipulator, and a laser beam.

Pre-implantation genetic diagnosis

If one or both partners are known to have abnormal genes or inherited conditions, we collaborate with the Reproductive Genetics Institute in Chicago and Dr Mark Hughes in Detroit, both world leaders in single gene disorders. In these cases, the embryo is biopsied and tested for up to 12 chromosomal aberrations as well as known translocations and single gene disorders. The result is obtained in 48 hours and the embryos are transferred on day 5.

The removal of the cell(s) does not cause any abnormalities of the future baby, however, it may decrease a chance of the embryo developing into a baby.

Therefore, at our center we are very selective about offering PGD and carefully consult every patient regarding the procedure benefits and risks.
