Yes, people should know the side effects of what they're taking, for any medical treatment, but like.. Who cares? "You shouldn't take the hormone because you can't knock people up and you'll be less horny." Those aren't objectively wrong things. They might not want kids, they might not want to be super horny, and they might not even wanna have a dick?? It might not make them better, but if it makes them more comfortable in their own bodies, that's a win.
