Sex hormone-binding globulin regulation of androgen bioactivity in vivo : validation of the free hormone hypothesis [PDF]

open access: yes, 2016
Sex hormone-binding globulin (SHBG) is the high-affinity binding protein for androgens and estrogens. According to the free hormone hypothesis, SHBG modulates the bioactivity of sex steroids by limiting their diffusion into target tissues.

Immunolocalization of steroidogenic enzymes in the vaginal mucous of Galea spixii during the estrous cycle. [PDF]

open access: yes, 2017
BackgroundThe synthesis of sex steroids is controlled by several enzymes such as17α-hydroxylase cytochrome P450 (P450c17) catalyzing androgen synthesis and aromatase cytochrome P450 (P450arom) catalyzing estrogen synthesis, both of which must complex ...

Gender ideology, same-sex peer group affiliation and the relationship between testosterone and dominance in adolescent boys and girls [PDF]

open access: yes, 2010
Although the role of testosterone in the aetiology of social dominance is often suggested, surprisingly few studies have addressed the relationship between sex steroid hormones and dominance as a personality trait. In this paper, the relationship between

Sex Steroids and Bone

open access: yesRecent Progress in Hormone Research, 2002
The adult skeleton is periodically remodeled by temporary anatomic structures that comprise juxtaposed osteoclast and osteoblast teams and replace old bone with new. Estrogens and androgens slow the rate of bone remodeling and protect against bone loss.

Sex steroid hormone modulation of neural stem cells: a critical review

open access: yesBiology of Sex Differences, 2019
While numerous in vivo experiments have sought to explore the effects of sex chromosome composition and sex steroid hormones on cellular proliferation and differentiation within the mammalian brain, far fewer studies as reviewed here, have explored these
