Abstract
The study investigated the influence of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 on the reproductive health indicators of cadets of military educational organizations. In the Department of Assisted Reproductive Technologies at the Clinic of Obstetrics and Gynecology of the Kirov Military Medical Academy, 183 male cadets aged 2127 years were divided into two groups and examined. The first group consisted of 132 cadets who had mild and moderate COVID-19, and the second group included 51 cadets without COVID-19 in the anamnesis. COVID-19 was found negatively affect the reproductive health of cadets. Individuals who previously had COVID-19 were found to have a significant decrease in the level of total testosterone and decreased concentration and mobility of sperm in the ejaculate. Moreover, in cadets without COVID-19 who were vaccinated with the combined vector vaccine Gam-COVID-Vac, the indicators of the hormonal profile and spermograms were within the reference values. The results indicate the need for further investigation of the effect of various negative factors, including severe acute respiratory syndrome coronavirus 2, on the reproductive health of cadets of military educational organizations. Moreover, the development of preventive, therapeutic, and rehabilitation measures will reduce the risk of infertility and reproductive losses, which is consistent with the interests of national projects on healthcare and demography.
