Hi, My son is 13. He is 5 ft 8 tall and weighs approx 149 pounds. His shoe size is still UK 6/US 7 so I guess it means his growth spurt has not started yet. I am 5 ft 8 and my husband is 6 ft 4. The problem is, I do not think his puberty has kicked in yet. The testicle sack seems to have enlarged and is hanging. I have not inspected the testicles up close but from some distance they do not seem much bigger (he did not have a long penis as a child to start with). Also, he does not have any pubic hear but there are some sparse light hairs under the arms. I have read that it is not the order things should come.. His voice has also not broken. And. I know that men do not get cellulitis, but I think he has some. If he crouches when he sits, I can see some dimples on his belly and if I squeeze his thigh or buttocks, the bumps appear. Long story short: Do I have a reason to suspect a chromosome disorder and get him tested? I would not like to make him concerned by dragging him to tests in vain.
