It can manifest as precocious puberty, and is caused by abnormally high levels of testosterone or estrogen, crucial hormones for sexual development. In some cases, it may be caused by a tumor, which can be malignant, but is more commonly benign. [2] Anabolic steroids may also be a major cause of high androgen and estrogen functional activity.
Menopause is associated with a rapid decline of estrogen, as well as a steady rate of decline of androgens. [12] The decline of estrogen and androgen levels is believed to account for the lowered levels of sexual desire and motivation in postmenopausal women, although the direct relationship is not well understood.
Aromatase excess syndrome (AES or AEXS) is a rarely diagnosed genetic and endocrine syndrome which is characterized by an overexpression of aromatase, the enzyme responsible for the biosynthesis of the estrogen sex hormones from the androgens, in turn resulting in excessive levels of circulating estrogens and, accordingly, symptoms of hyperestrogenism.

This activation of estrogen and testosterone causes physiological and psychological changes. Once activated, the HPG axis continues to function in men for the rest of their life but becomes deregulated in women, leading to ...
Although males are on average 2 centimetres (0.8 in) shorter than females before puberty begins, adult men are on average about 13 centimetres (5.1 in) taller than women. Most of this sex difference in adult heights is attributable to a later onset of the growth spurt and a slower progression to completion, a direct result of the later rise and ...
