My 11 year old son was sent for a bone age study at his annual physical. He is showing apparent signs of puberty. He has grown 4 inches in the year, has thin armpit hair and a few thin pubic hairs. His testicles have started getting larger (so I'm told). The bone age study showed advanced one age of 13 years +/- 10 months. We have been referred to a pediatric endocrinologist for follow up. What should we expect? What kind of treatment will he need? I am only 5'2 and my husband is only 5'6. My son is currently a smidge under 4'11. With an advanced bone age of 13 years, will he stop growing soon?
