Unfortunately, I think it's too soon for you to find the answer you're looking for, most studies out there aren't of the best quality, so no conclusions can be made yet. Having said that, here are two interesting articles, one being a "detox" protocol designed by Dr. Peter McCullough, read it and reach your own conclusions. The other article is about a small study where sperm quality decreased after a COVID infection.
I personally am skeptical of everything and simply advise having a healthy lifestyle until more conclusive information is brought out, that's a no brainer.
