“COVID-19 may harm sperm production”. Lets leave it there. It sounds like the statements made by governments about novichok and other agents.
Alarmist: yes I used this term pointedly because it is at present just that, there is no solid basis for a mass effect. Any sick person will have reduced sperm counts. I have not read the paper or blog, but like papers and blogs that are posted by conspiracy theorists, I also will have to limit my reading to the larger picture and avoid being bogged down by these sort of diversions. Having said that I may have to eat my words and have egg on my face eventually, but somehow I don’t think so.
