ObjectiveTo assess the association between number of embryos transferred and a measure of assisted reproductive technology success that emphasizes good perinatal outcome.MethodsWe analyzed assisted reproductive technology cycles initiated i…
ObjectiveTo assess trends in elective single ET and identify factors associated with a good perinatal outcome.DesignRetrospective cohort study.SettingClinic-based data.Patient(s)A total of 886,686 fresh, nondonor cycles reported to the Nati…
ObjectiveTo estimate trends in good perinatal outcomes (singleton live births at term with birthweight more than 2,500 g) among live births after assisted reproductive technology in the United States from 2000 to 2008, and associated factor…
