Preimplantation genetic testing (PGT) is a reproductive genetic technique aimed at preventing the transmission of severe genetic disorders. In France, its use is strictly regulated and reserved for complex medical situations, often associated with challenging reproductive histories and significant psychological burden. Despite scientific advances, success rates in preimplantation genetic testing remain limited, making the care pathway a significant source of uncertainty regarding the future of the parental project.
