Testosterone is the primary androgen — or male hormone — in your body. Low testosterone affects up to 39 percent of adult men in the US over the age of 45, and becomes increasingly prevalent ...
Administration of high-dose testosterone in men over a course of weeks can cause an increase in aggression and hypomanic symptoms, though these were seen in only a minority of subjects. [15] Acute high-dose anabolic-androgenic steroid administration in males attenuates endogenous sex hormone production and affects the thyroid hormone axis .
The discovery of testosterone in 1935 led to the development of testosterone replacement therapy (TRT), which has since become a cornerstone treatment for male hypogonadism. Additionally, hormone replacement therapy (HRT) for women has advanced, providing solutions for conditions such as menopause-related hypogonadism. [ 9 ]
Anabolic steroids influence cellular differentiation while favoring the development of muscle cells over fat-storage cells. [138] Research in this field has shown that structural modifications in anabolic steroids are critical in determining their binding affinity to ARs and their resulting anabolic and androgenic activities. [82]
Nandrolone decanoate has been studied in the treatment of bone loss in men, but in contrast to testosterone esters, was found to be ineffective. [ 55 ] [ 56 ] In short-term (6- to 8-week) studies in healthy male bodybuilders, nandrolone decanoate did not alter bone mineral density.
There is limited evidence that low-fat diets may reduce total and free testosterone levels in men. [172] Weight loss: Reduction in weight may result in an increase in testosterone levels. Fat cells synthesize the enzyme aromatase, which converts testosterone, the male sex hormone, into estradiol, the female sex hormone. [173]
