Adrenarche refers to the onset of dehydroepiandrosterone (DHEA) and DHEA‐sulphate (DHEA‐S) production from the adrenal zona reticularis that can be detected at around 6 years of age. The phenotypic result of adrenarche is pubarche or the development of axillary and pubic hair that occurs in both girls and boys at about age 8.

Data on adrenarche and pubarche in girls with Turner syndrome (TS) are inconsistent in the literature. The cohort consisted of 94 girls and young women with TS born between 1971 and 2001 (age range: 3.1–23.2 yrs.), who were treated with human growth hormone and regularly presented at our outpatient clinic every 4 to 6 months.The longitudinal data of all patients were ascertained

In a minority of individuals, pubarche occurs before true puberty (eg, when adrenarche causes pubarche before true puberty begins [ 10] or in the presence of hypogonadism [ 1 ]). Pubarche usually results from rising levels of androgens (male sex hormones) from the adrenal glands or the testes (premature adrenarche) but may also result from exposure of a child to an anabolic steroid. 2009-01-01 Adrenarche is the term for the maturational increase in adrenal androgen production that becomes biochemically apparent as a rise in dehydroepiandrosterone sulfate (DHEAS) at approximately six years of age in both girls and boys . 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. of these hormones to increase (something we call adrenarche) and for pubic hair to appear after age 8 in girls or 9 in boys.

Pubarche was defined as the appearance of pubic hair (PH2), whereas spontaneous puberty was defined as Tanner stage B2. Adrenarche, which typically precedes gonadarche, is associated with increased secretion of adrenal androgens and leads to the appearance of sexual hair (pubarche). The major adrenal bioactive C19 androgens are dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and androstenedione.

In most individuals, the first appearance of pubic hair (pubarche) occurs shortly after other signs of pubertal development. In a minority of individuals, pubarche occurs before true puberty (eg, when adrenarche causes pubarche before true puberty begins [ 10] or in the presence of hypogonadism [ 1 ]).

The phenotypic result of adrenarche is pubarche or the development of axillary and pubic hair that occurs in both girls and boys at about age 8. The medical name for the changes in the adrenal gland at puberty is adrenarche. Premature adrenarche is diagnosed when these signs of puberty develop earlier than normal and other potential causes of early puberty have been ruled out. The reason why this increase occurs earlier in some children is not known.
