Timing of puberty and final height are usually normal in girls with a history of premature adrenarche. However, these patients show an increased frequency of ovarian hyperandrogenism, hyperinsulinism and dyslipemia at adolescence. The hyperinsulinemia and lipid disturbances can often be detected in the prepubertal period, recommending long-term follow-up of these patients into adulthood. Premature adrenarche.

Pubarche usually results from rising levels of androgen and not estrogens in females, and androgens in males from the adrenal glands, ovaries, or testes but may also result from exposure to an anabolic Adrenarche is when a child's adrenal cortex starts to secrete adrenal androgen precursors. Dehydroepiandrosterone (DHEA) is the most abundant product of the adrenal cortex, and is a weak androgen agonist thought to be responsible for the clinical signs of pubarche by conversion to more potent androgens, testosterone, and dihydrotestosterone. Pubarche before 8 years of age usually is due to “premature adrenarche,” which is indicated by adrenarchal androgen levels—that is, DHEAS 40 to 130 μg/dL with other androgen levels in the marginally early pubertal range (see Table 15-1). 15,568 However, it may occur at androgen levels that are less (“idiopathic premature pubarche”) or more (“exaggerated adrenarche”).

Adrenarche (or pubarche) is considered premature when there is onset of pubic hair growth before age 8 in girls and before age 9 in boys. Because all children have an increase in adrenal androgen production between 6 and 8 years of age, it remains perplexing why hair growth is expressed only in a small minority. Timing of puberty and final height are usually normal in girls with a history of premature adrenarche.
