Erectile function in men with COVID-19 six months after recovery

Background. Based on the results of epidemiological studies, it was found that coronavirus disease 2019 (COVID-19) affects men more often than women. Among COVID-19 complications, erectile dysfunction is considered a marker of endothelial dysfunction and one of the main factors for the development of cardiovascular diseases. Lower total and free testosterone levels are predictors of adverse prognosis in males with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Testosterone deficiency syndrome is considered an independent risk factor of cardiometabolic disorders. The purpose of the study is to investigate the state of erectile function in men who suffered from COVID-19 six months after recovery. Materials and methods. Seventy-two men suffering from COVID-19 and being treated in an infectious disease hospital were examined 6.90 ± 0.29 months after recovery. Their average age was 45.23 ± 3.01 years. The control group included 18 conditionally healthy men aged 43.18 ± 2.90 years. The state of erectile function was assessed using the International Index of Erectile Function (IIEF). The concentration of testosterone was determined by the enzyme-linked immunosorbent assay with DRG (Germany) and DiaMetra (Italy) kits. All measurements were performed on the Stat Fax 3200 analyzer. Statistical comparison of the obtained results between groups was performed according to the Student’s test. A value of p < 0.05 was considered to be signifi­cant. Results. In addition to erectile dysfunction, as evidenced by a reduced corresponding integrative indicator “erectile function” of IIEF-15 in men with COVID-19, a decrease in sexual desire was found, as well as a deterioration of sensations in the form of a decrease in ejaculation frequency and orgasmic sensations during sex contacts. The average serum level of total testosterone was 10.9 nmol/l and was significantly reduced compared to that in the control group. Analysis of individual indicators showed that testosterone level was decreased in 10 patients and was within the normal range in 13 men with COVID-19. The average serum concentration of total testosterone in the examined men after the disease was 10.73 ± 1.07 nmol/l and was significantly reduced compared to that of the control group. Conclusions. There was an erectile dysfunction in men who suffered COVID-19, it was confirmed by a probable decrease in IIEF-15 score and integrative indicators of erectile function. A significant decrease in the blood conce
