Study: SARS-CoV-2 infection has no clear negative effects on human oocyte and early embryo development

Since December 2022, the nationwide control policy on the COVID-19 epidemic has been changed in China. Fertility and in vitro fertilization (IVF) centers are receiving increasing numbers of infected patients. However, there is still a lack of high-quality evidence on the effects of the virus on human oocytes and early-stage embryos. Previous studies have not found the virus in the follicular fluid of infected individuals.
