The new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that generated the COVID-19 pandemic is a broad-spectrum infection that besides the respiratory tract, can attack multiple organs, including the digestive, circulatory, and urinary systems. However, the negative consequences of SARS-CoV-2 on the male reproductive system have been largely ignored. The aim of this research was to see how SARS-CoV-2 affects the production of hormones, which are the markers of male reproductive function and fertility. The 350 Iraqi male participants were classified into two groups consisting of 150 COVID-19 recovered patients with a mean age of (32 ± 7.9) years and COVID-19 diagnosis confirmed by RT-PCR, and 200 apparently healthy male volunteers of similar age. The patients’ group was further divided into three groups depending on the recovery period of 3, 5 and 7 months. Serum levels of testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH) and prolactin were measured using the Mindray CL-1000i automated chemiluminescence analyzer provided with matching kits. When comparing the indices of COVID-19 recovered participants to the control group, the results revealed a decrease in testosterone level that was positively associated with the recovery period and an increase in the LH, FSH and prolactin levels that were negatively associated with the recovery period. It is supposed that infection with SARS-CoV-2 may be followed by a temporary condition of testicular failure.

The first half of the 20th century was marked by significant scientific advances in the study of hormones and vitamins. Among the first researchers working with hormones were F. Banting and J. Macleod, who discovered and characterized the pancreatic hormone insulin. This discovery catalyzed advances in the understanding of the mechanisms regulating biochemical processes – a new topic in the field of biological chemistry. The next important stage in the development of knowledge on biologically active substances was the works of organic chemists G. Wieland, A. Windaus, A. Butenandt and L. Ružička. They almost simultaneously identified and characterized the chemical structures of bile acids, vitamin D as well as female and male sex hormones. They found that all of these compounds are of a steroid nature and identified cholesterol as the starting material for their synthesis in the body. The studies of highly-active substances of steroid nature were continued by E. Kendall, F. Hench and T. Reichstein. They synthesized and investigated the structure and biological effects of corticosteroids, the hormones produced in the adrenal cortex. They were first to develop a method for the commercial manufacturing of cortisone, a hormone which is widely used to treat inflammatory processes. Thus, in the first half of the 20th century, organic chemists gave biochemists knowledge on the structure of essential for the human body substances – steroid compounds.
