I don't know if the docs don't realize they don't know the answer or if for some reason they are just reluctant to say I don't know. Must be something they teach in med school. It took me quite a few tries to actually pin my doc down on this question.
That's why i think it would be good if everybody asks it, so the docs really start thinking about it. So the question is: " What exactly is wrong with my eggs?" And don't let them get away with saying not of good quality! --respond with "what quality are you talking about?" Because it is not a chromosomal thing.
