3. “It is better to have tried, no matter what” : Psychological perspectives on pre-implantation genetic diagnosis (PGD)
Abstract : Couples with the risk of transmitting a genetic disease face different diagnostic options when they wish to become parents. Pre-implantation genetic diagnosis (PGD) combines in vitro fertilization (IVF) with biopsy of the embryo. With PGD the couple can start a pregnancy knowing that the child will not be affected by the particular disease. READ MORE
