Sure but if you're young, that's not going to do too much for your libido after you shut down.
Good point though, if it's a matter of legit. then you would just get a shot of test for HRT, but that's not necessarily to give boner powers, but it helps... if you're a 25 year old guy, I can't see you easily getting a shot though
Best solution is get a hot, young ladyfriend - that might get the wood moving.
