Ya usually age is a big factor. Also doctors cover themselves by prescribing things like clomid first due to the stigma of testosterone injections causing heart problems and probably cancer and all sorts of other misconceptions by the media.
Also, clomid is ideal if you can feel good on it. It doesn’t shut you down like testosterone does, and you’ll continue producing sperm to a high degree. And it’s easy. Just pop a pill everyday or every other day. It’s definitely the way to go if you feel great on it. But that’s the problem, a lot of men don’t feel good while on it. Me included.
But again to answer ur question, they are usually just covering themselves. They view it as safer with less risks, and therefore less chance they’ll get sued lol. But honestly, even with great HRT doctors, they usually like to at least try one clomid Protocol before going on TRT, especially if you’re still wanting to conceive children
