[Preimplantation genetic diagnosis].

ABSTRACT

In Denmark, preimplantation genetic diagnosis (PGD) is offered within the public healthcare to families with a known risk of an inherited disease in a child - as an alternative to prenatal diagnosis. It is a well-established technique with rather well-described perinatal- and neonatal outcomes, being comparable to what is seen following in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). The most common strategy is now to perform trophectoderm biopsy and then vitrify, while the diagnostic test is performed. Until 2013, 134 children have been born following PGD. Today, the clinical pregnancy rates are comparable to those following IVF/ICSI.
