Hi CrystalTipps,

I really am not an expert on PGD, just embryology. Here is a link to some FAQs about GSN, http://www.genesecurity.net/preimpla...ked-questions/. that might help you.

The source that would best be able to answer these questions is the PGD lab that is performing the assay on your embryos. The gene testing labs we worked with used to offer their genetic counselors to our patients -for free- to precisely answer these kind of questions. If you can find out the name of the lab that will do the testing, they probably have a website and contact info. I don't want to give you bad info. in general, my preference is to transfer on day 5 if the embryo is ready, not wait until day 6. I wish I could be more help. Good Luck! Carole
