The purpose of this study is to learn more about how puberty and treatments that slow down the progress of puberty affect bone health in youth.

As part of this study, your child will come to the research clinic at the main campus for a total of two study visits: a baseline visit and a follow-up visit 1 year later.

During the visit, we will take images of your child’s bones, and your child will complete questionnaires. Each visit will take about 3 ½ hours. There are no blood draws, and no medications will be given.
