Morphologic parameters of embryos vitrified on day 3. Before and after vitrification. Cells = mean number of cells; Comp = mean compaction index; Frag = mean fragmentation index; MN = mean number of multinucleated cells; Sym = mean symmetry index; V = vitrification; Vac = mean number of vacuolated cells; W = warming.
