ladies anyone knows what is the criteria for eggs to be matured aftr retrieval?i know once fertilised they wil b able to transfer into us as embryo . but shouldnt the dr knw whc are the matured eggs before they retrieve it out during ER ? or could it be that during scanning it looks matured but aftr taken out it is nt and so cannot be used ? i am not too sure about the matured part. i see so many sisters with so mny eggs retrieved yet alot not matured ,i am wondering why. i was even told once tt some eggs look lik an egg but aftr retrieval may realise they r not . is there such thing?
