Presence of SARS-CoV-2 RNA in Semen-Cohort Study in the United States COVID-19 Positive Patients

On 31 December 2019, China informed the World Health Organization they were facing a viral pneumonia epidemic of a new type of Coronavirus. Currently, 10 months later, more than 43,000,000 people have been infected, and about 1,150,000 deceased worldwide from the disease. Knowledge about the virus is updated daily, and its RNA was isolated from several human secretions, e.g., throat, saliva, pulmonary alveolar washing, and feces. So far, only one publication found the presence of SARS-CoV-2 in semen. In this 5-month cross-sectional study, we recruited 15 patients diagnosed with a positive nasal swab for SARS-CoV-2 with no or mild symptoms in our institution. A semen sample after a shower was retrieved and tested for viral RNA in the semen. The samples were tested for the viral RNA with RT-PCR with two different genetic probes. The samples were re-tested 24 h after the first test to confirm the results. The SARS-Cov-2 viral RNA was present in 1/15 patients [6.66%] in our sample. Even in a small sample, the RNA from SARS-CoV-2 can be isolated from human semen. This information should alert the scientific community and public health officials about a possible new form of transmission of the disease and long-term clinical effects on the population.
