<unk>  (Latin -<unk> s praecox) is an unusually early onset of<unk> , the process of sexual maturation that is triggered by the brain which usually begins in late childhood and results in reproductive maturity and completion of growth (Early<unk>  onset in children before the ages of 8 in girls and 9 in boys). Characteristics include early isolated pubic hair growth and early growth of female glandular tissue. Early<unk>  may be a variation of normal development, or may be a result of a disease or abnormal hormone exposure. In some contexts, the term is used more broadly to describe the early appearance of any of the physical features of<unk>  even if the complete, brain-directed process is not occurring.
