In vitro fertilization followed by genetic analysis of one cell from a 4- or 8-cell stage embryo and intrauterine transfer (also known as preimplantation genetic diagnosis) allows for the selection of embryos that do not carry the mutation causing cystic fibrosis. This method ensures that the child will be free of the disease without the need for further testing or potential termination of the pregnancy.
