Trend of twin rates per transfer during implementation of fresh single-blastocyst transfer program. All embryo transfers includes cycles undergoing fresh day 2, day 3, and day 5 transfer in women <35 years of age. All blastocyst transfers includes cycles undergoing the transfer of one, two, or three fresh blastocysts.
