ad·ren·ar·che

(ad-ren-ar'kē), Avoid the mispronunciation ad'renarche.
1. Growth of axillary and pubic hair induced by hyperactivity of the suprarenal cortex in early puberty.
2. Physiologic change at puberty caused by adrenocortical secretion of androgenic hormones or their precursors.
[adren- + G. archē, beginning]

adrenarche

[ad′rinär′kē]
Etymology: L, ad + ren; Gk, arche, beginning
the intensified activity in the adrenal cortex that occurs at about 8 years of age and increases the elaboration of various hormones, especially androgens.

adrenarche

The (normal) prepubertal increase in adrenal gland secretion—e.g., of  androgens—which begins from age 6 to 8.

ad·ren·ar·che

(ad-ren-ahrkē)
Increase in the production of androgens by the cortex of the suprarenal gland that occurs at the age of 8-9 years old.
[adren- + G. archē, beginning]

adrenarche

The changes in the outer layer of the adrenal gland that occur at puberty, with the production of male sex hormones (androgens) in both sexes that bring about some of the external sexual characteristics and hte prompting of libido.
