Genetic variants of sex hormone levels

The causal relationships between serum sex hormones and COVID-19 susceptibility and severity remain unknown. In this study, we systematically assessed the sex-specific causal effects of serum sex hormone levels, total testosterone (TT), bioavailable testosterone (BT) in particular, on COVID-19 outcomes based on two-sample Mendelian randomization (MR), using summary statistics of genome-wide association studies (GWASs). The data is about number of genetic variants after LD clumping and IVs for each sex hormone levels.
