Can coronavirus disease 2019 affect male fertility or cause spontaneous abortion? A two-sample Mendelian randomization analysis.

ABSTRACT: To investigate the causal relationship between two adverse reproductive outcomes (male infertility and spontaneous abortion) and COVID-19 infection using Mendelian randomization (MR) analysis. A two-sample MR study was conducted to examine potential causal links between COVID-19 infection severity and reproductive outcomes, using large-scale genome-wide association study (GWAS) summary statistics from European-ancestry populations. GWAS summary statistics were analyzed for COVID-19 phenotypes (infection: n = 1,683,769; hospitalized: n = 1,557,411; very severe respiratory-confirmed: n = 1,388,342; critical illness: n = 10,056) and reproductive outcomes (spontaneous abortion: n = 98,453; male infertility: n = 73,479). Causal estimates were calculated
