Abstract

For standardized reporting and to minimize diversities in reporting of embryo scoring, Istanbul global consensus scoring system for embryo has been used in the present chapter. The scoring system for blastocysts is a combination of the stage of development and of the grade of the inner cell mass (ICM) and of the trophectoderm (TE). It is a numerical interpretation of the Gardner scale. Different blastocysts in different stages of development and in different grades have been also explained in this chapter.
