Study question: what is the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the outcome of a pregnancy after medically assisted reproduction (MAR)?. Summary answer: our results suggest that MAR pregnancies are not differentially affected by SARS-CoV-2 infection compared to spontaneous pregnancies. What is known already: information on the effects of coronavirus disease 2019 (COVID-19) on pregnancy after MAR is scarce when women get infected during MAR or early pregnancy, even though such information is vital for informing women seeking pregnancy. Study design, size, duration: data from SARS-CoV-2 affected MAR pregnancies were collected between May 2020 and June 2021 through a voluntary data collection, organised by the European Society of Human Reproduction and Embryology (ESHRE). Participants/materials, setting, methods: all ESHRE members were invited to participate to an online data collection for SARS-CoV-2-infected MAR pregnancies. Main results and the role of chance: the dataset includes 80 cases from 32 countries, including 67 live births, 10 miscarriages, 2 stillbirths and 1 maternal death. An additional 25pregnancies were ongoing at the time of writing. Limitations, reasons for caution: an international data registry based on voluntary contribution can be subject to selective reporting with possible risks of over- or under-estimation. Wider implications of the findings: the current data can be used to guide clinical decisions in the care of women pregnant after MAR, in the context of the COVID-19 pandemic.
