PGS

Introduced in the nineties, Pre-Implantation Genetic Screening (PGS) involves studying the chromosomes of the embryos formed through In Vitro Fertilization (IVF) prior to transfer back to uterus. It is not common to include PGS as a routine procedure for all IVF cases however, in certain cases it proves to be invaluable.

Prior to transferring the embryos back to the uterus the embryos are studied using complex techniques. The aim is to rule out any chromosomal abnormalities that would ultimately lead to:

  • Failure of embryos to implant.
  • Miscarriage once pregnancy is achieved.
  • Getting pregnant with a child carrying a certain abnormality (eg. Down's Syndrome, cystic fibrosis…).

Once the embryos are studied, the healthy disease-free embryos are selected to be transferred back to the uterus after obtaining the couple's consent.
In a very selected group of patients, PGS could be offered for gender selection. Such cases are discussed within The Farah Hospital ethical committee.
