Since the outbreak of coronavirus disease 2019 (COVID-19), more than 130,000 people worldwide have been infected. Many studies show that the testis is one of the organs with a high expression of angiotensin-converting enzyme 2 (ACE2), the receptor/binding protein of SARS-CoV-2, which has aroused public concerns about the possible damage to male fertility. This article presents a review and analysis of the existing literature, aiming to achieve an objective understanding of the significance of the ACE2 expression in the testis. Hitherto, clinical and laboratory data available on COVID-19 are not sufficient to provide any direct evidence that the testis is a target organ of the virus. Whether the coronavirus damages fertility in male patients with COVID-19 requires further investigation. In the absence of sufficient research-based evidence, damage of the virus to male fertility should not be over-interpreted.
