IVF is not only a highly effective treatment for infertility, but also a secondary method (and so far is the only one that exists) that, through access to human eggs, allows diagnosing of many hereditary (genetic) diseases before the embryo is transferred into the uterus of the mother, that is, before pregnancy. This method is called preimplantation genetic diagnosis (PGD) of hereditary diseases.

This is made to prevent a transfer of embryos into the uterus with genetic disorders, and therefore the birth of children with congenital and hereditary diseases.

Before the PGD procedure it is important to consult a physician and geneticist and undergo a genetic testing – it will assess the possibility of genetic risks for particular couple and create a well-developed scheme for the future preimplantation genetic diagnosis procedure.

Who should undergo PGD:

• women of 40 years and older;
• men with infertility diagnosis (when aneuploidy in spermatozoa is confirmed);
• repetitive abortion;
• multiple failed attempts in IVF;
• sex determination, including the presence of sex-related diseases;
• chromosomal translocations of one parent. Preimplantation diagnosis is the only alternative method of prenatal diagnosis.
