I think I have male hypogonadism, I used to be a good student in school but from high school and college my concentration level dropped, I experience fatigue even for small work. My muscles don't have the strength as that of a normal 23 year old. My sex drive is considerably low Plus my sex organ hasn't grown since childhood. Whom should I consult ? I did had an accident when I was in 3rd grade, I hit my head to a gate and I bled. I was just given tetanus to prevent infection and the bleeding was stopped. Pls tell me whom to consult ?
