Pre implantation genetic diagnosis with Karyomapping is a highly sophisticated scientific technique which can test embryos for presence of a single gene disorder. This allows selection of embryos which are not affected by a specific disorder for embryo transfer during an IVF cycle, preventing the condition from being passed on to any future children. In vitro fertilization (IVF) is essential to carry out PGD. This process involves collecting several eggs from the ovaries and fertilizing them outside the body (in vitro) to produce several embryos. Each of the embryos can then be tested to find out which is healthy. Only embryos that are predicted to be free of genetic condition are transferred to the uterus and consequently if any pregnancy that begins has a low risk of being affected by disorder.
