Sequential vs. Monophasic Media Impact Trial (SuMMIT)

On day 5 or 6 of embryo development, all embryos will undergo a trophectoderm biopsy using the standardized technique, as according to standard laboratory protocol and without regard to study. Comprehensive Chromosome Screening (CCS) results will be available by the morning of day 6 if embryos are suitable for a fresh transfer which is the routine in our program.
