Preimplantation genetic testing is a technique which involves checking the genes or chromosomes of the embryos , created through IVF or ICSI, before they are transferred to the uterus.
This technique helps to ensure that only healthy embryos are put in the uterus during treatment and provides an alternative to current postconception diagnostic procedures (ie.amniocentesis or chorionic villus sampling),which are frequently followed by the difficult decision of pregnancy termination if results are unfavorable.
The embryologist can perform a polar body biopsy, a blastomere biopsy or a trophoblast biopsy to obtain genetic information from the embryo.
