Introduction

You or your child have been referred to the National Institutes of Health for evaluation of the effects of excess (too much) androgen due to Congenital Adrenal Hyperplasia (CAH). Too much androgen in childhood, if untreated, results in rapid growth, early puberty, and reaching adult height too soon resulting in short stature as an adult. Too much androgen in adulthood may result in infertility and women may have excess facial hair, acne and have a more male-like appearance. Excess androgen also may affect mood and behavior and possibly the secretion of other hormones. The most common genetic cause of early childhood androgen excess is Congenital Adrenal Hyperplasia (CAH).

We have ongoing studies at the National Institutes of Health Clinical Center to study many aspects of CAH. Our goal is to increase our understanding of the hormonal and genetic aspects of CAH, to improve the long-term outcome of patients with CAH, and to develop new treatment approaches.

To get started:

  • Navigate through the menu to learn more about the study.
  • Log in to the application and fill out questionnaires.
