Trying to get specific about punctuation and then saying that a subordinate clause is a parenthetical because it's acting like a normal subordinate clause is unhelpful, and also you're misreading it anyway because that's not what makes it read as more likely a hypothetical question. What makes it obviously more likely hypothetical is that it's asking about a situation someone can be in, that they can still need Viagra rather than do still need Viagra. Phrased another way, the question is "It's not deductively true that people with high T don't need Viagra, because someone with high T may not have a prostate and that could result in them needing it, right?" Like if I say to you, "You can be handsome and still have trouble getting laid if you're interpersonally annoying, right?" There's no suggestion that I'm claiming any of those things are true about you, I'm just indicating a situation using the general sense of "you." In my experience, people often use this wording to ask about themselves (whether their current situation or one they might be worrying about being in in the future).

It would be miles more normal to just word the original question "Despite having high testosterone, do you still need Viagra because you don't have a prostate?" or something like that (you can reorder the items, of course) if it was asking about Epstein's own condition.
