Cumul, cumulus–oocyte complex; Zona, zona pellucida; Perivit, perivitelline space; PBshape, shape of the first polar body; Oshape, shape of the oocyte; Darkdifg, dark ooplasm or diffuse granulation; VacRB, vacuoles, inclusions, refractile bodies; Cgran, central granulation; Spind, meiotic spindle; Multiple, multiple features evaluated together (by using a scoring system). PNM, pronuclear morphology; F, fertilization; CL, cleavage; ED, embryo development; EQ, embryo quality; CSE, cryosurvival of embryos; CM, compaction; BL, development to blastrocyst stage; HA, hatching; IM, implantation; CP, clinical pregnancy; OP, ongoing pregnancy; THB, take home baby; MB, multiple birth; PL, aneuploidy. −, not investigated; +, investigated, evaluated together with other features; No, investigated, no correlation found; Yes, investigated, correlation found. Underlined, effect on outcome contradicts the majority of investigations.
