Abstract

Objective: To determine whether embryo quality is associated with early spontaneous loss rates in twin and singleton pregnancies after IVF/intracytoplasmic sperm injection (ICSI). Design: Retrospective, single center analysis. Setting: The Center of Reproductive Medicine, Arcispedale Santa Maria Nuova, Reggio Emilia, Italy. Patient(s): Women undergoing IVF/ICSI and two- or three-embryo transfer of intermediate- and top-quality embryos. Intervention(s): First-trimester sonography at 6 to 7 weeks to determine number of embryos with positive heartbeat. Number of embryos lost was calculated from a second-trimester sonogram. Main Outcome Measure(s): Rates of total pregnancy loss, as related to embryo quality, initial number of embryos, maternal age
