title: Preimplantation genetic diagnosis.
abstract: Preimplantation genetic diagnosis (PGD) is an exciting new approach for the prevention of transmission of genetic disorders between generations. The use of genetically screened, healthy embryos to establish a pregnancy avoids the need for termination of an affected pregnancy, a procedure which can be traumatic physically and emotionally for potential patients, and is sometimes not available when needed. PGD usually follows the processes of ovarian hyperstimulation and in vitro fertilization (IVF). After carrying out appropriate genetic tests, only normal embryos are transferred to the patient's uterus to achieve an unaffected pregnancy and the birth of a healthy infant.
