“…Currently, assessment of embryo morphology remains the choice of method. The correlation between developmental potential and morphological parameters, such as the degree of fragmentation, presence and number of nuclei and size, number and symmetry of blastomeres per embryo at distinct inspection points is well-established [12,31,33,36,39,43]. Present morphological evaluation, however, requires inspection outside the controlled environment of the incubator, which exposes the embryos to undesirable changes in critical parameters: temperature, humidity and pH when evaluated [42].…”
