In general, the competence of oocyte is evaluated by maturation rate, fertilization rate, cleavage rate and blastulation ratio (Iwata et al., 2004).

This embryo had the expected annotation (according to the producer model) with first division at 24.7 h and start blastulation at 114 h (Figure 2).

Live Birth from the Transfer of a Severely Fragmented Embryo Observed by Morphokinetics

(14) Oocytes from women with a BMI >25 kg/[m.sup.2] are smaller and less likely to complete development postfertilization, with embryos arrested prior to blastulation containing more triglyceride than those forming blastocysts.

Fertility

Both genomic DNA and mitochondrial DNA in spent medium were significantly correlated with fragmentation rate, one of the morphologic parameters conventionally used for assessing embryo quality, and mitochondrial DNA mirrored the blastulation potential of both fragmented and high-grade embryos.
