“…This study showed that the testosterone to luteinizing hormone (T to LH) ratio in 81 patients with COVID-19 was dramatically decreased in comparison with 100 age-matched healthy counterparts (patients with COVID-19: 0.74; healthy men: 1.31, P < 0.0001). Serum T to LH ratio (as a predictor of male gonadal function) could be a potential marker of impairment of reproductive health by SARS-CoV-2 (ref.2).”
