Preimplantation Genetic Screening (PGS): Theoretical Attraction
The Center for Human Reproduction’s Dr. David H. Barad explains Pre-implantation Genetic Screening (PGS). PGS allows parents at risk of passing on a genetic condition to transfer only the embryos without that condition.
PGS means preimplantation genetic screening. The notion of PGS is very seductive. We, for years, observed in our patients as they aged that there were increasing genetic problems that could lead to failure of implantation. The notion of PGS is that if you have an array of embryos to choose from (that all look the same) doing a special test allows you to sort of peek inside at the genetics to choose the perfect embryo to transfer without genetic problems.
