RESUMEN
OBJECTIVE: A novel type of Coronavirus was identified in China in December 2019. The first cases of a form of pneumonia of unknown etiology were detected at the beginning of that month in Wuhan. The virus is believed to have emerged at the Wuhan Huanan Seafood Market, where transmission of a zoonotic pathogen to humans occurred. PATIENTS AND METHODS: Some studies conducted in China during the epidemic report small numbers of pregnant women infected with SARS-CoV-2 and some pregnancy complications in patients with COVID-19. However, they fail to document the transplacental passage of the virus from mother to fetus. RESULTS: Following the COVID-19 outbreak, guidelines for couples who are undergoing treatments of assisted reproduction have been issued by the International Federation for Fertility Societies (IFFS), the American Society for Reproductive Medicine (ASRM), the European Society of Human Reproduction and Embryology (ESHRE) and the Latin American Network of Assisted Reproduction (REDLARA). They recommend couples to discuss assisted reproduction with their doctors while those at risk or with SARS-CoV-2 should consider freezing oocytes or embryos and retransferring them later. CONCLUSIONS: Other than the US, Italy is the country with the highest number of cases (197675 positives, 26644 deaths) (updated on April 26). The Italian National Transplant Centre and the Higher Institute of Health advised on March 17 to complete the cycles already started and not to start new cycles. Phase 2 will begin on 4 May with an increase in freedom of action and fertilization treatments will start again. The Society that brings together embryologists (SIERR) has issued the guidelines to be followed when this happens.
