both of my sons are currently experiencing delayed puberty. They are receiving injections of testosterone to help move things along.<br> <br> I ended up growing to 6'3" but never really developed that much muscle and I have always had a problem with low energy and problems with concentration and embarassingly, my genitals are small. My doc has me on ADHD meds and I am wondering if maybe low testosterone is my problem. I am 40 years old. Do you think I am crazy or is there a possible link?
