Preimplantation Genetic Screening (PGS)
What Is PGS And Why Should You Consider Utilizing It With Your IVF Cycle?
Preimplantation Genetic Screening (PGS) is a genetic test that is proven to increase your chances of a successful pregnancy. In addition, it contributes to having a healthy and happy pregnancy. PGS was first introduced for use with IVF in the United States in the mid 1990s. PGS allows for the determination between normal (euploid) embryos from abnormal (aneuploid) ones. PGS testing evaluates all 46 chromosomes, the 44 non-sex chromosomes plus X and Y. When an embryo is tested using PGS, the test identifies whether or not the embryo contains: the correct amount of genetic material, the correct number of chromosomes and the correct copies of them, too.
Who Can Benefit from PGS?
On-going research has shown that about 50% of embryos tested with PGS are aneuploid and this rate significantly increases with one’s age; especially, after the age of 35. As a result, PGS screeningis appropriate for nearly ALL IVF patients. Research also has shown IVF pregnancy rates increase by more than 20% in patients who’ve utilized PGS screening versus those that have not.
