Genetic trait selection with in vitro fertilization (IVF)

IVF can be combined with Preimplantation Genetic Diagnosis (PGD) where we test one or more cells from each developing embryo. PGD can be used for most single gene disorders (diseases caused by one gene) such as cystic fibrosis, Huntington’s, Polycystic Kidney Disease, etc. We can also test for chromosome rearrangements like translocations, or testing embryos for genetic ‘normality’ (formerly called Comprehensive Chromosome Screening or CCS). PGD can be performed for family balancing for couples who have at least one child and desire a child of the opposite gender. PGD cannot be used to select height or any other physical characteristic or intelligence and should not be used to select eye color or other appearance traits.
