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.



[ 32] A An adult-type of these hormones to increase (something we call adrenarche) and for pubic hair to appear after age 8 in girls or 9 in boys. The reason why this increase occurs earlier in some children is not known. We do know that being overweight increases a child’s chances of having PA, but many children with PA are not overweight. 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).

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 ]).

Young Lean Women with Evidence of Both Premature Adrenarche and Pubarche Display a Metabolic, Hormonal and Psychologic Profile that is Similar to that of their Peers with PA-PP women had significantly lower serum total cholesterol (165±20 vs 187±28 mg/dl), LDL (87±21 vs 21±12 mg/dl) and higher HDL (65±11 vs 56.2±10.9 mg/dl 2021-03-31 Adrenarche is the puberty of the adrenal gland.

Precocious pubarche (PP) is defined as pubic hair onset before age 8 in girls and age 9 in boys (1– 5). In 80 to 95% of cases, PP is related to premature adrenarche (PA), the nonpathological precocious secretion of adrenal androgens ( 6 , 7 ).

Girls with excessive BMI had a significantly higher prevalence of breast appearance from ages 8.0 through 9.6 years and pubarche from ages 8.0 through 10.2 years than those with normal BMI. Menarche was also significantly more likely to occur in preteen girls with an elevated BMI.

There is one adrenal gland on top of each kidney. Pubarche is preceded by a gradual increase in production of adrenal androgens, DHEA and Δ4-androstenedione (Adione), a process termed adrenarche. Objective To study the natural course of pubertal transition and the associations with adrenarche, body fat, and linear growth. 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.
