I used PGD to avoid passing on a genetic condition. As far as what you experience as a patient, there is very little difference to standard IVF other than the expense, and also a bit more anxiety as the embryos grow and are biopsied, since most do not make it. We started with 12 eggs, but come biopsy time there were only 2 embryos that were suitable for testing. Both were OK and were transferred, and we have a son.

My Dr was strongly in favour of transferring 2 embryos - though that may not be the preference if you are having PGD for miscarriage problems rather than to avoid nasty genes.
