The impact of Hurricane Katrina, a major natural disaster, on assisted reproductive outcomes through an analysis of 451,848 ART cycles
Abstract To evaluate whether pregnancies conceived via assisted reproductive technology and exposed to Hurricane Katrina (HK), one of the most destructive natural disasters in United States history, were more prone to adverse perinatal outcomes, miscarriages, or sex disparities compared with pregnan...
