In cases of very poor egg quality, or if a woman has no eggs (e.g. because of premature menopause), eggs donated from another woman can be used. At present, there are no proven interventions for improving egg quality so donated eggs remain the only option for treating very poor egg quality. The awareness that poor egg quality is a problem typically occurs after previous failed IVF treatment cycles. The tell-tale sign of poor quality eggs during IVF treatment is poor embryo development; this is because embryo quality is very heavily dependent upon egg quality.
