Blastocoele expansion degree predicts live birth after single blastocyst transfer for fresh and vitrified/warmed single blastocyst transfer cycles.
Blastocysts were categorized as Grade I; excellent or good quality blastocysts with blastocoele filling the entire blastocyst, compact inner cell mass (ICM), multicellular cohesive trophectoderm (TE) and oval shaped, Grade II; moderate quality blastocysts with normal ICM, but no optimal (fragmented or necrotic) TE, and Grade III; poor quality blas tocysts with very few cells or without ICM and with large vacuole instead of blastocoel.

Blastocysts were incubated for a further 2-3 hours to allow blastocoele expansion and herniation of the trophectoderm cells from the zona, at which time the embryo was placed into 20 [micro]L of medium (Vitrolife) under oil for biopsy.
