Androgens and estrogens are concerned in the development and maintenance of secondary sexual characteristics, such as breasts, external genitalia, body hair distribution and so on. Male pattern baldness is to some extent determined genetically, and may be countered in women by the presence of estrogens.
The three major naturally occurring forms of estrogen in women are estrone (E1), estradiol (E2), and estriol (E3). Another type of estrogen called estetrol (E4) is produced only during pregnancy. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males compared to females, estrogens nevertheless also have important physiological roles in males.
