I just came across an article from Reuters talking about some fertility clinics not disclosing the risks of performing pre-implantation genetic diagnosis:
NEW YORK (Reuters Health) - Fertility clinic websites aren't doing a great job of explaining the risks of testing an embryo for genetic disorders before it's implanted in the womb, researchers found.
The procedure, known as pre-implantation genetic diagnosis (PGD), can be used to test for 5,000 different genetic disorders and, more controversially, choose the sex of an infant. But it's not 100-percent reliable, and could, in rare cases, cause harm to the embryo or even destroy it.
