OBJECTIVE: To investigate the presence of viral RNA in human semen of patients with severe acute-respiratory syndrome coronavirus 2 (SARS-CoV-2) and to evaluate its presence and relevance in semen parameters.
DESIGN: Pilot cohort study.
SETTING: University hospital.
PATIENT(S): Thirty-four men were distributed as: 1) patients in convalescence (patients with confirmed SARS-CoV-2 infection in pharyngeal swab according to reverse-transcription polymerase chain reaction [RT-PCR] or antibodies); 2) negative control group (no antibodies); and 3) patients with an acute infection (detection of SARS-CoV-2 in pharyngeal swab).
INTERVENTION: Semen and a blood sample were collected from each individual.
MAIN OUTCOME MEASURE(S): Analysis of semen quality according to the World Health Organization standards. Detection of SARS-CoV-2 by RT-PCR in the native semen sample and after density gradient preparation. Confirmation of immunoglobulin (Ig) A und IgG antibodies in the blood.
RESULT(S): Eighteen semen samples from recovered men were obtained 8-54 days after absence of symptoms, 14 from control subjects, and 2 from patients with an active COVID-19 infection. No RNA was detected by means of RT-PCR in the semen, including semen samples from two patients with an acute COVID-19 infection. Subjects with a moderate infection showed an impairment of sperm quality.
CONCLUSION(S): A mild COVID-19 infection is not likely to affect testis and epididymis function, whereas semen parameters did seem impaired after a moderate infection. SARS-CoV-2 RNA could not be detected in semen of recovered and acute COVID-19-positive men. This suggests no viral transmission during sexual contact and assisted reproductive techniques, although further data need to be obtained.
