The combination of pronuclear and blastocyst morphology: a strong prognostic tool for implantation potential

摘要

PurposeTo (i) investigate a possible association between different features of pronuclear (PN) morphology and different features of blastocyst morphology, (ii) evaluate the combination of PN and blastocyst morphologies as a predictive factor for ICSI outcomes and (iii) identify possible contributing factors to poor PN morphology.
