Increased number of cells in day 3 embryosis associated with higher live birth rate in D5 vitrified–thawed single blastocyst transfer cycles

Cell number in 3-day-old (D3) embryos influences pregnancy outcomes in patients undergoing cleavage-stage embryo transfer. However, the association between D3 cell number and pregnancy outcomes following 5-day-old (D5) vitrified–thawed single blastocyst transfer remains underexpl...
