Pre-Implantation Genetic screening is utilized to evaluate the embryo genetically and chromosomally. This approach is used to determine if an embryo is defective or has a congenital illness. Only the finest embryos will be implanted in this manner, lowering the likelihood of a sick fetus.
Previously, only five of the entire 23 chromosomes could be studied. However, using PGS, all 23 chromosomes may be studied, providing greater insight into the embryo’s profile.
As a result, only the best and undamaged embryos are placed into the woman’s uterus using this procedure. This is an excellent alternative to the presently used post-conception diagnostic methods, which may result in a selective pregnancy termination if something is wrong with the baby.
PGS is now the sole method for avoiding the high risk of having a kid with a genetic condition before conception. It is an enticing method of avoiding a hereditary condition.
At what point in the treatment is it possible to do this?
In an IVF cycle, the preimplantation genetic screening (PGS) stage is one of the steps. After the eggs have been collected, the sperm and the eggs are combined to create an embryo. Embryos are the first cells of a developing baby. At this point, the Pre-Implantation Genetic Screening procedure is carried out, during which the genetic composition of the embryo is investigated.
During an embryo transfer, the woman’s uterus receives the embryo that is considered to be the healthiest and most viable option.
How can we determine whether or not we require PGS?
The following circumstances often call for the use of pre-implantation genetic screening.
- Multiple In Vitro Fertilization failures
- Recurrent miscarriages
- In the event that either of the prospective parents has a congenital illness, such as thalassemia or colorblindness, the baby may be affected.
- Nevertheless, the doctor evaluates each case on its own merits before deciding whether or not a certain method is necessary for the couple.
