Sequential embryo assessment outperforms investigator-driven morphological assessment at selecting a good quality blastocyst

Fertil Steril. 2006 Mar;85(3):794-6. doi: 10.1016/j.fertnstert.2005.08.064.

Abstract

Two selection methods (morphology-only and a sequential embryo assessment algorithm) were compared within the same IVF clinic to determine which method best identifies the embryos on day 3 that will develop into the highest quality on day 5. The sequential embryo assessment algorithm was significantly better at selecting the best embryo and selecting a blastocyst compared with the morphology-only method.
