**Abstract**

The infection of SARS-CoV-2 and its COVID disease caused several economic and social disturbances worldwide. This chapter aimed to determine the severity of SARS-CoV-2 infection on the testicular hemostasis. This overview showed the possible mechanisms of how the SARS-CoV-2 can infect the testes. SARS-CoV-2-induced pneumonia, cytokine storm, and immunosuppressive state may transfer from the respiratory tract to the blood circulation, binding to testicular angiotensin-converting enzyme 2 receptors (ACSE2) and initiate its intracellular replication and action (cytotoxicity), that disrupting the testicular hemostasis. In severe states, COVID-19 disease can increase body/testes temperature, which may destroy the germ cell in the long term. The final mechanism is that SARS-CoV-2 infection causes stress, panic, and anxiety states, causing brain disorders that may perturb the hypothalamic–pituitary-testes-axis (HPTA). This disturbance may then lead to testicular dysfunction. The severity of COVID-19 may be age-dependent and depending on the expression and distribution of testicular ACSE2 receptors. Also, this chapter not only showed the sexual transmission of SARS-CoV-2 but also followed its impact on sexual behavior, pregnancy, and progeny. Thus, maintaining the testicular hemostasis may play a vital role in a healthy life for the offspring. Further research and clinical studies are required to explore this issue.
