Is a preimplantation screening vital for IVF or should it only be done when the parents carry a hereditary condition?

Preimplantation screening is one of the tools we use in assisted reproduction to help couples who need it. It should however be carried out when there are specific indications and not on everyone without exception. Indeed it is employed on couples with a hereditary disorder so we can ascertain the condition of the embryos. In this case, a PGD (preimplantation genetic diagnosis) is performed in which specific genetic disorders are tested for, such as thalassaemia and cystic fibrosis. Thus, only the healthy embryos are transferred to the uterus. However, PGS can also be of help to other couples. Couples suffering repeated miscarriages or failed IVF attempts as well as women of an advanced reproductive age can benefit from checking embryos for chromosomal abnormalities. Our mission once again is to transfer only healthy embryos so as to increase the chances of success
