Standardization of grading embryo morphology

Fertil Steril. 2010 Aug;94(3):1152-3. doi: 10.1016/j.fertnstert.2010.05.042. Epub 2010 Jul 2.


Standardization of morphologic assessment for an embryo grading system was developed and is being implemented by the Society for Assisted Reproductive Technology (SART). A recent European consensus conference of embryologists from Europe and America is working toward adopting an embryo classification system modeled similarly to that of SART that, if adopted, would produce a de facto international standard to aid cross-border collaboration.
