Diagnostic préimplantatoire

Pre-implantation genetic diagnosis provides an alternative to prenatal diagnosis for couples who are at risk of having an offspring with a serious genetic disorder. This novel method is based on recent molecular techniques (PCR, FISH) that allow analyzing the genetic status of embryos obtained after in vitro fertilization. Only embryos free of the genetic disorder are transferred into the uterus. It is too early to establish the safety and accuracy of pre-implantation genetic diagnosis.
