This preprint explores the effects of Covid-19 on sexual hormone levels in men. The study finds that LH levels are elevated, FSH and testosterone levels are the same. And they hypothesize that Covid-19 impairs testosterone production, so the body boosts LH levels to compensate, bringing testosterone back to its previous level. Possibly there is some effect on sperm production, but this study did not look for that. As they note, the medical literature says that the testes are the tissue with the highest expression of ACE2 receptors in the body.
