PGT-A (Preimplantation Genetic Testing for Aneuploidy)

(earlier known as PGS: Preimplantation Genetic Screening)
Preimplantation screening is a genetic examination of embryos before their reintroduction into the woman’s uterus. The examination allows us to choose the euploid embryo or embryos, or those with a standard number of chromosomes and without any identified genetic abnormality, and therefore increase the chance of pregnancy or limit the risk of miscarriage or the birth of a child with a chromosome defect.

PGT-M (Preimplantation Genetic Testing for Monogenic/Single Gene Diseases)

(earlier known as PGD: Preimplantation Genetic Diagnosis)
Preimplantation genetic diagnostic is therefore a method which enables us to choose a so-called “healthy embryo” without specific genetic impairment. The main advantage of such procedure is the elimination of risk of the foetus carrying monitored genetic impairment. The couple therefore do not have to deal with any potential issues connected with an artificial abortion of the pregnancy. The principle and procedure as seen by the couple is similar to that of the PGT-A method.
