A study published this week in JAMA Network Open showed that the semen of 16% of COVID-19 patients, including patients at the acute stage of infection as well as patients that were recovering, tested positive for the SARS-CoV-2 virus

it is important to note however that finding evidence of the virus does not necessarily mean that it is infectious and the disease can be passed on sexually.

also the study authors stress "This study is limited by the small sample size and the short subsequent follow-up. Therefore, further studies are required with respect to the detailed information about virus shedding, survival time, and concentration in semen."

on the other hand it might be interesting to do a study looking for antibodies in the semen of recovered patients - this may be an interesting root^H^H^H^Hroute to acquiring immunity!

of course don't try this at home without advice from your friendly health care practitioner!
