What are the pro’s and con’s of PGD (Preimplantation Genetic Diagnosis)?
There are no substantive data at this time to indicate that routine performance of embryo biopsy for chromosomal analysis increases the chance of a live birth in a donor egg cycle, unless there is a known chromosomal abnormality (e.g. a translocation) of the man providing the sperm or the woman providing the egg. The latter is very rare. Embryo biopsy carries a small risk of damaging the embryo and reducing its viability, and the procedure may be quite expensive. It is sometimes performed by clinics when patients desire sex identification for family balancing.
