ACTIONS OF THE ADRENAL ANDROGENS



ACTIONS OF THE ADRENAL ANDROGENS






Many actions of adrenal androgens are exerted through their conversion to active androgens or estrogens such as testosterone, dihydrotestosterone, estrone, and estradiol. In men, <2% of the biologically important androgens are derived from adrenal production, whereas in women ˜50% of androgens are of adrenal origin. The adrenal contribution to circulating estrogen levels is mainly important in pathologic conditions, such as feminizing adrenal tumors. Adrenal androgens contribute to the physiologic development of pubic and axillary hair during normal puberty. They also play an important role in the pathophysiology of congenital adrenal hyperplasia, premature adrenarche, adrenal tumors, and Cushing syndrome (see Chap. 75, Chap. 77 and Chap. 83).
