[Male fertility in the context of COVID-19: Concern and considerations]

Area of Science:

• Reproductive medicine
• Virology
• Urology

Background:

• Coronavirus disease 2019 (COVID-19) has infected millions globally.
• The testis expresses high levels of angiotensin-converting enzyme 2 (ACE2), the SARS-CoV-2 receptor.
• This has raised concerns about potential impacts on male fertility.

Purpose of the Study:

• To review and analyze existing literature on ACE2 expression in the testis.
• To provide an objective understanding of the significance of ACE2 in male reproductive health.
• To address public concerns regarding COVID-19 and male fertility.

Main Methods:

• Literature review and analysis of current clinical and laboratory data.
• Examination of studies reporting ACE2 expression in testicular tissue.
• Assessment of evidence linking SARS-CoV-2 infection to testicular damage.

Main Results:

• Current clinical and laboratory data are insufficient to confirm the testis as a direct target organ of SARS-CoV-2.
• No direct evidence currently exists to prove COVID-19 damages male fertility.
• The significance of ACE2 expression in the testis concerning viral infection requires further investigation.

Conclusions:

• The potential damage of SARS-CoV-2 to male fertility is currently not supported by sufficient scientific evidence.
• Further research is necessary to definitively determine if COVID-19 affects male reproductive function.
• Overinterpretation of potential male fertility damage in the absence of robust data should be avoided.
