英文摘要: Objective(#br)To document the risk of in vitro monochorionic dizygotic twin formation in the implementation of a program of blastocyst biopsy with preimplantation genetic screening (PGS).(#br)Design(#br)Case report.(#br)Setting(#br)Private infertility laboratory.(#br)Patient(s)(#br)Prospective PGS patients with intracytoplasmic sperm injection–derived, group-cultured blastocysts over a 3-year period.(#br)Intervention(s)(#br)Group culture in Global medium (Life Global) to optimize blastocyst formation of zygotes produced for blastocyst biopsy for PGS (n ≤ 8 embryos/25 μL droplet), and laser zona dissection (LZD) of all day-3 cleaved embryos to promote pre-expansion trophectodermal extrusion at the blastocyst stage (i.e., premature hatching).(#br)Main Outcome Measure(s)(#br)Blastocyst...
