Despite our best attempts to identify sperm that is not likely to fertilize, on occasion there is an unfortunate lack of fertilization. Second day or rescue ICSI does not have the same good prognosis as when ICSI is performed immediately. In some cases this is because the lack of fertilization is due to an egg factor. In other cases normal eggs are just too post mature when the prcodure is done. Success has occurred, but at a significantly lower rate. Ask your RE if they think this was an egg or a sperm problem. If you are not succesful ICSI should be done primarily in future attempst.
: Just had a retrieval and had to have emergency ICSI - totally unfamiliar with process - Does anyone know if pg rates are lower w?ICSI - what about miscarriage and birth defects. We are considering not doing transfer because ICSI was done to fertilize- are our fears unfounded
