My son is 16 years old and I know he isn't going to grow to be 6' tall as his father is 5'8" and I am 5'4". My son is currently 5'2" and weighs approx. 101lbs. The question I have is about him not having any signs of going through puberty other than his voice deepening. He has no facial hair, no underarm hair, he has told me there has been some hair growth in the pelvic region. I took him to the doctor about 1 year ago and they did a blood test to check his hormone levels and found that his growth hormone level was very high. Is is normal for him to have no other signs of puberty at this age with the levels of hormones that he has? Should I take him back to the doctor or just wait it out for another year or so? I should say that the doctor did check to see if there were any sexual organ growth and at that time he said on the scale that is used he should have been a 5 and was not even a 2 yet. I have tried to as delicately as possible bring this up with my son again to see if there has been any progress but as it was very embarrassing for the both of us I didn't really get a definitive answer. Any help or direction as to what to do next (if anything at all) would be greatly appreciated. Thanks!!
