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.
Estrogen is actually a generic term that encompasses several different types of similar female hormones. The most potent form of estrogen is generally considered to be estradiol, which is the type used in many of the studies we describe. Estrogens achieve their effects in the body by changing the expression of certain genes in target cells. Estradiol is soluble in cell membranes, so it can pass easily into the cell.
