Pubarche refers to the first appearance of pubic hair at puberty. Pubarche[1] is one of the physical changes of puberty and can occur independently of complete puberty. 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 steroid.[2]
When pubarche occurs prematurely (in early or mid-childhood), it is referred to as premature pubarche or precocious puberty and may warrant an evaluation. Premature adrenarche is when hormones are elevated at an early age. It is the most common cause of premature pubarche. Some cases of premature pubarche can be due to congenital adrenal hyperplasia, androgen-producing tumors of the adrenals or gonads.[3] When adrenarche, central puberty, and all pathologic conditions have been excluded, the term isolated premature pubarche is used to describe the unexplained development of pubic hair at an early age without other hormonal or physical changes of puberty.
Average age
The average beginning of pubarche varies due to many factors, including climate, nourishment, weight, nurture, and genes. First (and often transient) pubic hair resulting from adrenarche may appear between ages 10–12 at the beginning of puberty.
