Day 3 embryo shape as a morphologic selection parameter in in vitro fertilization
Journal of Assisted Reproduction and Genetics, 08/20/2012
Kamran S.C et al. – The aim of the stduy was to investigate whether embryo shape is a useful morphologic predictor of developmental competence in IVF cycles. Based on this retrospective analysis, the weak association of day 3 embryo shape with implantation potential suggests that this morphological characteristic is unlikely to be a useful additional marker for embryo selection after cell number, fragmentation, and blastomere symmetry. Further studies are planned to assess applicability of these conclusions to embryos of varying stages and grades.
