PGT-A: Preimplantation genetic testing for aneuploidies
Preimplantation genetic testing for aneuploidies (PGT-A) determines the number of chromosomes in an embryo and thus increases the chances of embryo implantation and the birth of a healthy child.Book a consultation
Missing or additional chromosomes in the embryo can cause:
Failure to implant (nest) in the mother’s uterus.
Spontaneous miscarriage in the 1st trimester of pregnancy.
The birth of a child with, for example, Down, Edwards or Patau syndrome.
PGT-A preimplantation testing is most often performed on an embryo in the blastocyst stage (5th day of development) and does not affect its development. In fact, it will help infertile couples increase the success rate of transfer above 40%, even if transferring a single embryo.
