Its called Kallman's syndrome and its a condition where you can never hit pueberty it can effect males and females. So basically you will be pubescent for the rest of your life. And hormone injections don't work they will put you on it for a while but as soon as they take you off of it your testosterone goes back to extremely low levels.

I need to apologize to @thewaterbear apparently I got some of my facts mixed up they don't have a sense of smell and their puberty is delayed but with testosterone injection the condition can be reversed but they just have to be on it for the rest of their life otherwise they will grow out of puberty again.
