  • Title: Premature adrenarche.
    Author: Leung AK, Robson WL.
    Journal: J Pediatr Health Care; 2008; 22(4):230-3. PubMed ID: 18590867.
    Abstract:
    Premature adrenarche refers to the precocious secretion of adrenal androgens, which results in the isolated development of pubic hair (pubarche) before the age of eight years in girls and nine years in boys. The female to male ratio is approximately 10:1. Dark, coarse and curly hair is limited initially to the labia majora in girls and to the root of the penis in boys. The hair extends gradually into the pubic region. Axillary hair, increased body odor, and acne can also be present. Hirsutism, deepening of the voice, clitoral enlargement, breast development, and phallic or testicular enlargement are characteristically absent. A transient acceleration of growth is common but final height is usually not affected. The onset of puberty usually occurs at the normal age. Premature adrenarche can be a forerunner of polycystic ovary syndrome and/or syndrome X. Continued observation and periodic re-evaluation is necessary.
