PGS Meaning and
Definition
-
PGS is an acronym that stands for Preimplantation Genetic Screening. It refers to a cutting-edge screening technique used in the field of reproductive medicine. PGS is primarily applied during the process of in-vitro fertilization (IVF) to assess the genetic health of embryos before they are implanted into the uterus.
The goal of PGS is to identify embryos that carry chromosomal abnormalities, such as aneuploidies (missing or extra chromosomes), which can lead to a variety of genetic disorders, birth defects, or even unsuccessful pregnancies. By analyzing the genetic composition of embryos at an early stage, PGS aids in selecting the healthiest and most viable embryos to maximize the chances of a successful pregnancy.
PGS involves the removal of a few cells from the developing embryo, which are then analyzed using advanced genetic testing techniques. These techniques may include fluorescent in situ hybridization (FISH), polymerase chain reaction (PCR), or next-generation sequencing (NGS), among others. The genetic analysis provides valuable information about the number and structure of the chromosomes, allowing clinicians to identify any abnormalities.
The information obtained through PGS enables reproductive specialists to make informed decisions about which embryos to implant, thus increasing the chances of a successful pregnancy outcome and potentially reducing the risk of passing on genetic conditions to offspring. PGS has revolutionized the field of assisted reproductive technology by helping couples facing infertility issues to have a higher likelihood of conceiving a healthy child.
