Successful Pregnancy and Delivery after Multifetal Pregnancy Reduction in A Woman with Monochorionic Triplet Pregnancy Following Intracytoplasmic Sperm Injection and the Transfer of Frozen-thawed Embryos

This was the first report of multifetal pregnancy reduction (MFPR) with monochorionic triplet pregnancy following ICSI and the transfer of frozen-thawed embryos. A 30-year-old woman who had undergone ICSI and the transfer of frozen-thawed embryos subsequently developed monochorionic triplet pregnancy. She did a multifetal pregnancy reduction to remove one embryo limb from the fetal sac and remained a singleton pregnancy after pregnancy reduction. At last she delivered a healthy baby girl at 40 weeks of gestation. In conclusions, an early stage fetal reduction, selection of the appropriate reduction week, and the expertise of a highly experienced doctor using ultrasound can ensure a wonderful pregnancy outcome in monozygotic multiple pregnancies.
