Once the spike protein binds to ACE2, transmembrane protease serine 2 ( TMPRSS2) on the host cell surface primes the spike protein and other cellular proteases to cleave the spike protein into two subunits. Entry into host cells is facilitated by the viral spike protein and host cell receptor angiotensin-converting enzyme 2 ( ACE2). The spike proteins play a crucial role in receptor recognition, cell attachment, and fusion during viral infection. It is comprised of a nucleoprotein around an RNA genome, a viral envelope, and a spike protein. SARS-CoV-2 is a single-stranded RNA virus of the coronavirus family. Our goal is to provide an update on the most recent literature. In the realm of men’s health, persistent questions remain regarding viral tropism, gender susceptibility, impact on semen parameters, hormones, sexual health, and the impact of vaccine on fertility. Since the first vaccine was authorized by the FDA for emergency use in the United States on Decemabout half of the US population have been fully vaccinated ( ).Īs the pandemic continues to evolve with emerging variants and a growing volume of scientific literature, it is important for healthcare providers, policymakers, the media, and the general public alike to stay up to date on the latest literature. This ultimately led to the development of multiple effective vaccines in under a year, an impressive and unprecedented accomplishment. Initially, very little was known about SARS-CoV-2 and COVID-19, but the medical and research community responded accordingly with a tremendous volume of research within a short period of time to better understand the virus and disease to offer better strategies for diagnosis, treatment, and prevention. Since severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first detected in December 2019 in Wuhan, China, there have been over 186,000,000 confirmed cases and over 4,000,000 deaths worldwide attributed to coronavirus disease 2019 (COVID-19) ( ).
