Premature Sexual Development

Abstract

When a child matures sexually before eight or nine, physicians should try to ferret out a cause. In about 75 percent of girls and 40 percent of boys no cause will be found, even after x-rays, electroencephalograms, blood and urine hormone assays, and thyroid studies. But in the other children, lesions affecting the hypothalamus, ovarian or testicular tumors, or adrenal disorders will usually be found.
