[Androgenic status in men during COVID-19].

Abstract

Background: COVID-19 is a disease that has a negative systemic effect on the human body, including the male gonads. Therefore, the androgenic status in men with COVID-19 needs to be studied.

Aim: To evaluate the levels of total testosterone, sex hormone binding globulin (SHBG) and free testosterone in men in the acute phase of COVID-19 and during convalescence.

Materials and methods: A continuous dynamic prospective study of 70 men with moderate to severe COVID-19 at the age of 50[44; 64] years. During the study, the levels of total testosterone, SHBG were determined with further calculation of the level of free testosterone by Vermeullen. The data were collected twice - at the patient's hospitalization and at his discharge. The differences between the groups were considered statistically significant at p <0.05.

Results: At the time of hospitalization for COVID-19, hypogonadism syndrome was observed in 61 people - 87%. Patients with hypogonadism did not statistically significant differ in age and severity of COVID-19 disease compared to men without hypogonadism. Inpatient treatment lasting 12[10;14] days resulted in a statistically significant increase in the levels of total testosterone from 4,7[2,96;8,48] to 12,85[8,62;19,2] nmol/l, p<0,001; SHBG from 27,87[20,78;36,57] to 33,76[26,27;52,60] nmol/l, p<0,001 and free testosterone from 107[65;174] to 235[162;337] pmol/l, p<0,001. This led to the elimination of hypogonadism in 28 patients - 40%. Patients with persistent hypogonadism were statistically significantly older than men with normalized testosterone, there were no statistically significant differences in the initial levels of total testosterone, SHBG and free testosterone, and there were also no differences in the prevalence of severe COVID-19 (3,97[2,86;7,46] vs 4,26[2,93;5,96] nmol/l, p=0,100; 28,76[20,78;48,59] vs 24,63[18,85;31,70] nmol/l, р=0,994; 100[58;118] vs 96[64;143] pmol/l, p=0,522; 24 против 18%, p=0,754, respectively).

Conclusion: COVID-19 has a pronounced negative effect on the production of testosterone in men, leading to the development of laboratoric hypogonadism, which is potentially reversible. The reversibility of laboratoric hypogonadism is typical for younger patients.
