Although this involves only a small proportion (∼0.2%) of testosterone output, the higher molar potency of estradiol (∼100-fold higher vs. testosterone) makes aromatization a potentially important mechanism to diversify androgen action via ER-mediated effects in tissues where aromatase is ...
In any case, this result indicates that high-T participants might have been better able to override defensive retaliatory responses, although the effect of T on aggression might be better explained by other factors such as testosterone-to-estradiol aromatization73,74 than by amygdala reactivity alone...
The influence of these hormones in this study is likely limited, because the women were investigated during their follicular phase when progesterone and estradiol concentrations are lowest and similar to those in men. In addition, testosterone levels are also relatively low during the follicular phase...

SI conversion factors: To convert testosterone to nanomoles per liter, multiply by 0.0347; to convert free testosterone to picomoles per liter, multiply by 3.47; to convert estradiol to picomoles per liter, multiply by 3.67. Figure 3. Effects of Testosterone or Placebo Treatment for 12 Months ...

In this non-controlled investigation, 5 obese women took 400 mg of purified I3C every day for 2 months. At the end of the study, all of the women had significant increases in estradiol 2-hydroxylation, i.e., the breakdown of an estrogen hormone. ...
Higher concentrations of intracellular T and estradiol in obese SAT were also observed (2.4 vs. 1.3 ng/g, p = 0.013 and 0.075 vs. 0.22 ng/g, p = 0.004, respectively). Testosterone accumulation resulted in even lower expression in androgen-responsive genes involved in lipoly...
Estradiol is a pleiotropic hormone that has instrumental influence over numerous critical functions related to the cardiac and vascular system, bone and mineral metabolism, cognition, memory, mood, balance, age-related neurodegenerative disorders and lipolysis(burning) of fat. When a doctor places a ...
