42. In fact, an estrogen causes the sexual dimorphism of the brain...

In developing male fetuses, the immature testes produce testosterone, which is converted by the brain into estradiol; the presence of estradiol in the brain results in a 'male' brain pattern. In developing female fetuses, the absence of significant levels of testosterone/estradiol causes the brain to develop as a 'female' brain. The brain becomes sexually dimorphic during a critical period, or window of time, which in humans occurs during fetal development. From that point, the brain sex is determined for life; thus at puberty, circulating testosterone and estrogen act on a brain that is already sexually dimorphic.

From Wikipedia: Estradiol:

Estradiol (E2 or 17?-estradiol, also oestradiol) is a sex hormone. Estradiol is abbreviated E2 as it has two hydroxyl groups in its molecular structure. Estrone has one (E1) and estriol has three (E3). Estradiol is about 10 times as potent as estrone and about 80 times as potent as estriol in its estrogenic effect. Except during the early follicular phase of the menstrual cycle, its serum levels are somewhat higher than that of estrone during the reproductive years of the human female. Thus it is the predominant estrogen during reproductive years both in terms of absolute serum levels as well as in terms of estrogenic activity. During menopause, estrone is the predominant circulating estrogen and during pregnancy estriol is the predominant circulating estrogen in terms of serum levels. Estradiol is also present in males, being produced as an active metabolic product of testosterone. The serum levels of estradiol in males (14 - 55 pg/mL) are roughly comparable to those of postmenopausal women (< 35 pg/mL). Estradiol in vivo is interconvertible with estrone; estradiol to estrone conversion being favored. Estradiol has not only a critical impact on reproductive and sexual functioning, but also affects other organs, including the bones.
