Objective To describe detection of severe acute respiratory syndrome (SARS)–coronavirus 2 (CoV-2) in seminal fluid of patients recovering from coronavirus disease 2019 (COVID-19) and to describe the expression profile of angiotensin-converting enzyme 2 (ACE2) and Transmembrane Serine Protease 2 (TMPRSS2) within the testicle.

Design Observational, cross-sectional study.

Setting Tertiary referral center.

Patient(s) Thirty-four adult Chinese males diagnosed with COVID-19 through confirmatory quantitative reverse transcriptase–polymerase chain reaction (qRT-PCR) from pharyngeal swab samples.

Intervention(s) None.

Main Outcome Measure(s) Identification of SARS-CoV-2 on qRT-PCR of single ejaculated semen samples. Semen quality was not assessed. Expression patterns of ACE2 and TMPRSS2 in the human testis are explored through previously published single-cell transcriptome datasets.

Result(s) Six patients (19%) demonstrated scrotal discomfort suggestive of viral orchitis around the time of COVID-19 confirmation. Severe acute respiratory syndrome–CoV-2 was not detected in semen after a median of 31 days (interquartile range, 29-36 days) from COVID-19 diagnosis. Single-cell transcriptome analysis demonstrates sparse expression of ACE2 and TMPRSS2, with almost no overlapping gene expression.
