Coronaviruses are a group of RNA viruses that primarily affect the respiratory system and cause the common cold, fever, and coughs in mammals and birds. However, in some cases, coronaviruses are associated with more serious and lethal conditions, such as pneumonia, bronchitis, and severe acute respiratory syndrome .

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) originating from Wuhan, China, led to a global health crisis. SARS-CoV-2 had infected more than 450 million people, resulting in more than 6.6 million deaths. The World Health Organization (WHO) declared coronavirus disease 2019 (COVID-19), the infectious disease caused by SARS-CoV-2, a pandemic, and many states enacted strict rules, such as border closures, transportation restrictions, and quarantine.

Quality and satisfying sexual life have a positive effect on the social and daily relationships as well as on the intimate life of many individuals. The WHO summarizes the definition of sexual health as the physical, emotional, mental, and social well-being of an individual. On the other hand, sexual dysfunction can be described as any condition preventing the individual from being satisfied by the sexual activity at any stage of the sexual relationship.

The renin-angiotensin system (RAS), also ACE 2 and TMPRSS2 play an important role in the cellular entry for SARS-CoV-2. Because the male genital system presents high ACE 2 expression, the importance of this pathway increases in COVID-19 cases. As the COVID-19 pandemic has affected the male genital system in direct or indirect ways and showed a negative impact on male reproduction Ozer Baran and Aykut Aykac et al reported that the fear of infection and transmission of the disease to the partner that occurs during the Covid-19 pandemic manifests itself in the form of a decrease in the frequency and quality of sexual intercourse.
