Pre-genetic screening and diagnosis are advanced techniques used during IVF to check embryos for genetic or chromosomal abnormalities before implantation. These tests help identify healthy embryos, increasing the chances of a successful pregnancy and reducing the risk of genetic diseases being passed on to the child.
1. Pre-Genetic Screening (PGS/PGT-A):– Focuses on analyzing embryos for chromosomal abnormalities, such as missing or extra chromosomes, which can lead to failed implantation, miscarriage, or genetic disorders like Down syndrome.
2. Pre-Genetic Diagnosis (PGD/PGT-M):– Specifically looks for single-gene disorders or known hereditary conditions in embryos (e.g., thalassemia, cystic fibrosis, sickle cell anemia).
Pre-genetic testing is recommended for couples who:
* Have a family history of genetic disorders
* Are carriers of known genetic mutations
* Have experienced recurrent miscarriages
* Have had repeated failed IVF cycles
PGS (Pre-genetic Screening / PGT-A) checks embryos for chromosomal abnormalities (extra or missing chromosomes).
PGD (Pre-genetic Diagnosis / PGT-M) is used when one or both parents are carriers of specific genetic disorders, and it tests embryos for those particular diseases.
Couples with a family history of genetic conditions, carriers of inherited diseases, women over 35, couples with multiple IVF failures, or those who have experienced recurrent miscarriages are advised to consider PGS/PGD.
Embryo biopsy is a highly advanced and safe procedure. Only a few cells are taken from the embryo at the blastocyst stage, and it does not harm the embryo’s development.
No test can give a 100% guarantee, but PGS/PGD significantly reduces the chances of transferring embryos with genetic or chromosomal abnormalities, improving the likelihood of a healthy pregnancy.
No. It is generally recommended in high-risk cases such as advanced maternal age, repeated miscarriages, family history of genetic disorders, or unexplained IVF failures.
NYes. By selecting chromosomally normal embryos, PGS/PGD can improve implantation rates, reduce miscarriage risks, and increase the chances of a successful pregnancy.
