Adrenarche was assessed by serum DHEAS levels and pubertal status by Tanner stages. 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).

However, dissociation between pubarche and biochemical markers of adrenarche can occur in girls with precocious puberty, who have pubarche long before adrenarche (34-35). 1995-05-01 Precocious pubarche: distinguishing late-onset congenital adrenal hyperplasia from premature adrenarche. Armengaud JB, Charkaluk ML, Trivin C, Tardy V, Bréart G, Brauner R, Chalumeau M J Clin Endocrinol Metab 2009 Aug;94(8):2835-40. 2012-03-25 Condition in which there is early onset of pubic hair (pubarche) and/or body odor that occurs before age 8 years in girls and before age 9 years in boys No true pubertal development (ie, no breast development in girls, no testicular growth in boys), nor evidence of clitoromegaly or penile growth in idiopathic premature pubarche or premature adrenarche 2019-10-11 The ‘exaggerated adrenarche’ group had higher 17 OHPreg/17OHP ratios at 60 minutes after stimulation but these were not diagnostic for 3β‐HSD deficiency. CONCLUSION The value of assessing basal steroids in children presenting with premature adrenarche Is demonstrated in this series with 5·7% being diagnosed with 21‐hydroxyiase deficiency and 9·1% with ‘exaggerated adrenarche’. “Traditionally, pubarche or adrenarche before the age of 8 in girls or before the age of 9 in boys was considered early.

Over premature pubarche Kinderen die te vroeg schaamhaar (pubisbeharing) krijgen, hebben last van premature pubarche.

Background: Data on adrenarche and pubarche in girls with Turner syndrome (TS) are inconsistent in the literature. Methods: 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 Premature adrenarche is the most common cause of the early appearance of pubic hair ("premature pubarche") in childhood. In a large proportion of children it seems to be a variation of normal development requiring no treatment.

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. Previous reports claim that pubarche should not necessarily present true puberty in a considerable number of boys older than 10 years of age with normal development. Indeed, it seems that in most cases, the presentation of isolated pubarche is to be the consequence of isolated adrenarche.

First (and often transient) pubic hair resulting from adrenarche may appear between ages 10-12 preceding puberty.. During puberty pubarche tends to occur earlier in females than males, as with most puberty stages and puberty as a whole. The average beginning of pubarche varies due to many factors, including climate, nourishment, weight, nurture, and genes. 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. AAs are secreted in small amounts during infancy and early childhood and their secretion gradually increases with age, paralleling the growth of the zona reticularis.
