@Lastround - as many have already explained PGD is when they look at all the chromosomes for abnormalities - it's not just the common trisomies, they look at all of them. I have had 5 tested across three cycles and all have had at least one chromosomal abnormality. The testing means I saved myself 5 transfers of abnormal embryos. Happy to explain more about the process if you need.
Im not with Wazza but to answer your question - yes I know there are several over 40 s ladies who have been successful with Wazza with their own eggs. The other girls will be able to be more specific.
