This comment is simply not on topic. The article doesn't claim that testosterone is correlated with Covid19 in any way, it merely says that it might be, and solicits further research. So your question isn't a response to anything in the article. The HN guidelines explicitly say to not accuse people of not reading the article, but it's hard to have any reasonable discussion if people don't.
