• Earlier it was called Preimplantation Genetic Screening (PGS).
• The aim is to look for presence of any aneuploidies (extra or missing chromosome) of the embryo.
• It can help to select the embryos with normal chromosomal pattern which will have highest chance of becoming healthy babies.
• It is done when there is no known evidence of a genetic abnormality in either parent.

Who can benefit from PGT-A ?

• Female partner age 38 or older.
• Couples interested in single embryo transfer.
• History of repeated pregnancy loss.
• History of repeated failed IVF.
• Couple with more number of embryos can choose to select the normal embryo to decrease ‘ time to pregnancy ‘.

• It was earlier called Preimplantation Genetic Diagnosis( PGD ).
• It is recommended when there is known risk of passing down a genetic abnormality to future offspring.
• Genetic test report of affected family member is analysed in details to plan treatment for the couple.

Who can benefit from PGT-M?

Personal or family history of single-gene defects—such as cystic fibrosis, haemophilia, sickle cell anaemia, muscular dystrophy, citrullinemia , multiple exostosis etc.

• Chromosomal structural rearrangements are translocations, inversions, duplications or deletions of part of chromosome.
• Many time carriers of structural rearrangement are apparently healthy individuals.
• Most of the times structural rearrangements are suspected & detected only when such individual suffer from repeated IVF failure, repeated miscarriage or birth defects in their babies.

Who can benefit from PGT-SR ?

In known carriers of chromosomal structural rearrangement normal embryos can be selected by PGT SR.
