Androgen

One of a class of steroid hormones. Androgens play a major role in the development and maintenance of masculine secondary sexual characters, for example, the seminal vesicle and prostate gland of the male mammal, and the comb, wattles, and spur of the male fowl. They also influence certain other secondary sexual characters, such as hair growth pattern and voice quality in humans. In the fowl, they affect the pattern and seasonal coloration of its feathers, as well as crowing. In addition, androgens affect nitrogen metabolism (anabolic). Androgens are produced in the testis, ovary, adrenal, and most likely, in the placenta. A small portion of the androgen is from corticoids, or adrenal cortex steroids, and from other C21 steroids, such as progesterone. See Hormone, Ovary, Progesterone, Steroid, Testis

In most of the studies it has been seen that girls with premature adrenarche (the onset of pubic hair before the age of 8 years is associated with elevated levels of adrenal androgens and no evidence of true puberty or adrenal dysfunction) may be at increased risk for development of polycystic ovarian syndrome (PCOS).
The clinical symptoms of CAH directly result from either the deficiencies in mineralocorticoid or glucocorticoid production or from the overproduction of adrenal androgens.

Although this pioneering study can be criticized for its lack of an experimental control group, its extremely limited sample size, and its use of a physically traumatized participant population, the results strongly suggested that adrenal androgens do influence what Waxenberg et al.

This is a poor definition, as we know that the hormones responsible for pubic hair are adrenal androgens and have nothing to do with the activation of estrogen production by the ovaries.
