Preimplantation Genetic Screening, commonly referred to as PGS, is a modern fertility technique used to examine embryos for chromosomal abnormalities before implantation. Unlike PGT, which focuses on specific genetic conditions, PGS screens all chromosomes to identify embryos with the correct chromosomal number, thereby reducing the risk of miscarriage and improving the chances of a successful pregnancy.

PGS is particularly recommended for women above 35, couples who have experienced repeated IVF failures, or those with a history of miscarriage. By selecting embryos with the right chromosomal structure, PGS helps increase implantation success and gives couples greater confidence in achieving a healthy pregnancy.

In the PGS process, a small number of cells are gently removed from developing embryos without harming them. These cells are then analyzed in the laboratory to detect any chromosomal abnormalities. Only embryos with normal chromosomal composition are chosen for transfer, ensuring that the embryo has the highest potential for healthy development.

By identifying chromosomally normal embryos, PGS enhances the success rate of IVF, lowers the risk of miscarriage, and supports the birth of healthy babies. It is a valuable tool for couples seeking to maximize their chances of conception, particularly when age or previous fertility challenges may pose a risk.
