COVID-19 (coronavirus disease) - Fertility and Pregnancy

Coronavirus disease (COVID-19) is caused by a new strain of Coronavirus (SARS-CoV-2) discovered in 2019 and not previously identified in humans. Common symptoms  include fever, cough, and shortness of breath. On March 11, the World Health Organization (WHO) announced the current COVID-19 outbreak as a pandemic. Currently there are more than 681 million confirmed cases globally (data from March 9, 2023). According to data from Our World in Data, on March 9, 2023, 69.7% of the world population had received at least one dose of a COVID-19 vaccine, and 28% of people in low-income countries have received at least one dose.

What is currently known about COVID-19 and pregnancy

In May 2020, WHO reported there was no known difference between the clinical manifestations of COVID-19 in pregnant and non-pregnant women of reproductive age. The available data on the exact effects of COVID-19 on fertility and pregnancy remained scarce. Cochrane Gynaecology and Fertility joined the University of Birmingham and WHO to collaborate on the development of a living systematic review on COVID-19 in pregnancy. In March 2021, an updated version of the living systematic review and meta-analysis Clinical manifestations, risk factors, and maternal and perinatal outcomes of coronavirus disease 2019 in pregnancy was published in the BMJ. The updated review included 192 studies (64,676 pregnant women with COVID-19; 569,981 non-pregnant women with COVID-19). Results from the update showed that pregnant and recently pregnant women were more likely to need intensive care treatment for COVID-19 compared to non-pregnant women of reproductive age. Several risk factors for severe COVID-19 in pregnancy were identified - pre-existing comorbidities, non-white ethnicity, chronic hypertension, pre-existing diabetes, high maternal age, and high body mass index. Pregnant women with COVID-19 are more likely to deliver preterm compared to pregnant women without COVID-19. Babies born to mothers with COVID-19 are more likely to be admitted to the neonatal unit. On March 16, the living systematic review SARS-CoV-2 positivity in offspring and timing of mother-to-child transmission was published in the BMJ. The review included 472 studies (28 952 mothers, 18 237 babies). Evidence suggested confirmed vertical transmission of SARS-CoV-2, although this is likely to be rare. Severity of maternal covid-19 appears to be associated with SARS-CoV-2 positivity in offspring.

COVID-19 and pregnancy loss

On November 28, 2023, we published our systematic review "COVID-19 in pregnant women: a systematic review and meta-analysis on the risk and prevalence of pregnancy loss" in Human Reproduction Update. Our study found no indication that SARS-CoV-2 infection in the first or second trimester increases the risk of miscarriages.

Resources on COVID-19, pregnancy, fertility, and vaccination

Here we have gathered important resources, guidance and advice statements from international organizations and societies related to COVID-19, fertility and pregnancy. We are working on updating the information below as soon as new guidelines become available.  

We have also created an Excel sheet that contains data extracted from all published reports on pregnancy and neonatal outcomes in women with confirmed COVID-19. Please note that this data table has not been peer reviewed. If you have unpublished data on pregnancy and neonatal outcomes in women with confirmed COVID-19 from your institute, and you would like us to include it in the database, please contact dr Madelon van Wely ( 

Update: as of March 2023, the database will not be updated on a regular basis. However, we plan to resume our activities if needed.
