PREGNANCY LOSS RATES AFTER SINGLE, EUPLOID FROZEN-THAWED EMBRYO TRANSFER IN THE COVID-19 ERA

Abstract

Data on the impact of COVID-19 on early pregnancy is extremely limited, and patients and practitioners remain cautious about initiating pregnancy in areas of high SARS-CoV-2 transmission.1-4 In April 2020, during the peak of the pandemic, the prevalence of COVID-19 among New York State residents was estimated to be 22.7%, consisting largely of asymptomatic infection.5 If SARS-CoV-2 is pathogenic to early pregnancy, an increase in loss might be expected given this high transmission. The objective of this study is to determine if an increase in early pregnancy loss occurred in patients undergoing single euploid frozen embryo transfer (FET) during the height of the COVID-19 pandemic.
