Dear Editor, I would like to discuss the publication "Investigation of SARS-CoV-2 in semen of patients in the acute stage of COVID-19 infection" [1] . Kayaaslan et al. [1] concluded that "although all semen samples were obtained in the acute stage of the infection when the nasopharyngeal swab test was positive, we did not detect SARS-CoV-2 in semen." In fact, there are some previous reports showing no existence of pathogen in semen samples [2, 3] . Nevertheless, a recent meta-analysis still noted that there is still a requirement for caution on the possibility of COVID-19 transmission via sexual contact [4] . In fact, there is a very low possibility that semen will be the body fluid leading to disease transmission. During a sexual contact, the distance between partners is very short, and the chance of transmission by respiratory contact should be a more important consideration [5] .
There is no conflict of interest.
