Preimplantation genetic diagnosis (PGD) is a key technique in modern reproductive medicine. Originally developed to help couples who were at risk of transmitting single-gene genetic abnormalities to their children, the development of the FISH technique broadened chromosome analysis to include detection of more complex inherited abnormalities. The last decade has seen the development of aneuploidy screening (PGS) for infertile couples, using the same techniques as PGD but screening for as many chromosomes as possible. PGD has always been a controversial procedure and embryo manipulation and selection is still illegal in some countries. The second edition of this leading textbook describes all aspects of PGD, with chapters written by key international experts in the field. A must for anyone interested in learning more about PGD, it will be of interest to everyone working in the fields of IVF, genetic diagnosis, genetic counselling, and prenatal diagnosis - including clinicians, embryologists, nurses, and clinical scientists.
