- "The work is the latest of a string of advances in a field known as pre-implantation genetic diagnosis, in which eggs or embryos are tested for disease genes and only embryos lacking such genes are transferred into a woman's womb."

- "Preimplantation genetic diagnosis (PGD) can help couples to have a successful pregnancy and a child free from specific genetic disorders. Embryos are tested for genetic disorders before they enter the uterus (womb) and before pregnancy has started."
- "Preimplantation genetic diagnosis (PGD) is a new method of prenatal diagnosis that is developing from a union of in vitro fertilization (IVF) technology and molecular biology. Briefly stated, PGD involves the creation of several embryos in vitro from the eggs and sperm of an interested couple. The embryos are permitted to develop to a 6-to-10-cell stage, at which point one of the embryonic cells is removed from each embryo and the cellular DNA is analyzed for chromosomal abnormalities or genetic mutations.1 An embryo or several embryos found to be free of genetic abnormalities are subsequently transferred to the woman's uterus for gestation. Embryos found to carry a genetic abnormality are discarded or frozen. Extra normal embryos may be frozen for future transfer or donation to another couple."
.
"Embryos are obtained by combining eggs and sperm in the laboratory (In vitro fertilization - IVF). From each embryo, one or two cells are removed and tested. If the embryo is judged to be free of the disorder it can be transferred to the uterus."
