BACKGROUND: A potential role of testosterone among sex hormones has been hypothesized in identifying sex‐related differences in the clinical consequences of severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) infection. Due to the high global prevalence of hypogonadism, the relationship between hypogonadism and SARS‐CoV‐2 infection outcomes deserves an in‐depth study. OBJECTIVE: The present study aimed to investigate the relationship of serum testosterone with other laboratory parameters on the prognosis of coronavirus disease‐19 (COVID‐19) in male patients with COVID‐19 diagnosis. MATERIALS AND METHODS: This prospective cohort study included 358 male patients diagnosed with COVID‐19 and 92 COVID‐19 negative patients admitted to the urology outpatient clinics as a control group. The COVID‐19 patients were divided into groups according to prognosis (mild‐moderate and severe group), lung involvement in chest computed tomography (<50% and >50%), intensive care unit needs, and survival. RESULTS: The measured serum total testosterone level of the COVID‐19 patients group was found to be significantly lower than that of the control group (median, 140 ng/dl; range, 0.21–328, 322 ng/dl; range, median, 125–674, p < 0.001, respectively). The serum TT levels were statistically significantly lower in severe COVID‐19 patients compared to mild‐moderate COVID‐19 patients (median, 85.1 ng/dl; range, 0.21–532, median, 315 ng/dl; range, 0.88–486, p < 0.001, respectively), in COVID‐19 patients in need of intensive care compared to COVID‐19 patients who did not need intensive care (median, 64.0 ng/dl; range, 0.21–337, median, 286 ng/dl; range, 0.88–532 p < 0.001, respectively), and in COVID‐19 patients who died compared to survivors (median, 82.9 ng/dl; range, 2.63–165, median, 166 ng/dl; range, 0.21–532, p < 0.001, respectively). DISCUSSION AND CONCLUSION: Our data are compatible with low TT levels playing a role on the pathogenesis of the disease in Covid‐19 patients with poor prognosis and a mortal course and may guide clinicians in determining the clinical course of the disease.
