When comparing men and women in the 30-, 50-, and 70-year age groups, young and middle aged men showed increased testosterone after exercise, with the latter also having increased cortisol. Elderly men showed no change. [25] Other studies have also shown with age there is a downtrend of testosterone [26] and attenuated growth hormone response. [27]
The EC 50 of DHT for activation of the AR is 0.13 nM, which is about 5-fold stronger than that of testosterone (EC 50 = 0.66 nM). [50] In bioassays, DHT has been found to be 2.5- to 10-fold more potent than testosterone. [47] The elimination half-life of DHT in the body (53 minutes) is longer than that of testosterone (34 minutes), and this may ...
Androgen replacement therapy (ART), often referred to as testosterone replacement therapy (TRT), is a form of hormone therapy in which androgens, often testosterone, are supplemented or replaced. It typically involves the administration of testosterone through injections, skin creams, patches, gels, pills, or subcutaneous pellets.
The anabolic effects are important in both males and females, although females have lower circulating levels of androgens. The physiologically most important androgens are testosterone (T) and dihydrotestosterone (DHT), which are considered classical androgens because their role in human health was discovered in 1930s. [1]
It comes from testosterone and helps develop typically “male” sex characteristics like increased muscle mass, body hair, and a deep voice. While DHT isn’t a “bad” hormone, over time, it ...

A variety of factors may lead to this condition such as hormonal effects , age, diet, autoimmunity , emotional stress, physical stress, drug effects, genetics , or infections .

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.
