PGS- Pre Implantation Genetic Screening

Preimplantation Genetic Screening (PGS) is a specialized technique used in assisted reproductive technologies, particularly in the context of in vitro fertilization (IVF). It involves testing embryos for chromosomal abnormalities before they are transferred to the uterus during an IVF cycle. The primary goal of PGS is to enhance the chances of a successful pregnancy by selecting embryos with a higher likelihood of implantation and a lower risk of genetic disorders.

The results of PGS can help doctors select the embryos that are most likely to result in a successful pregnancy and a healthy baby. PGS can also reduce the risk of miscarriage and increase the chances of a successful IVF outcome. 

For whom PGS is done?
 

PGS is typically recommended for couples undergoing in vitro fertilization (IVF) who are at increased risk of having a baby with a chromosomal abnormality or a genetic disorder. This may include:
 

Women over  35: As women age, the risk of chromosomal abnormalities in  eggs increases. PGS can help identify embryos with chromosomal abnormalities, reducing the risk of implantation failure or miscarriage. 
 
 
Couples with a history of recurrent pregnancy loss: PGS can help identify  chromosomal abnormalities in  embryos that may contribute to recurrent miscarriage. 
 
 
Couples with a history of chromosomal abnormalities or genetic disorders: PGS can help identify embryos with the same chromosomal abnormality or genetic mutation, allowing doctors to select unaffected embryos. 
 
 
Couples undergoing IVF for non-medical reasons: Some couples choose PGS to improve their chances of having a healthy baby.
