      Comprehensive chromosome screening (CCS) is becoming more frequently utilized to aid in embryo selection and optimize live birth rates. Level I data supports the safety and accuracy of trophectoderm (TE) biopsy, but not all TE biopsies are equal. Whether the size of the biopsy impacts reproductive potential is unknown.
