5 alpha reductase (5-AR) converts testosterone into DHT, which is a much more potent androgen than testosterone. anabolic steroid books Obesity finches. As a result, the androgenic signal of testosterone is "amplified" in 5-AR rich tissues. The significance of 5 alpha-reduction to the psychosexual actions of testosterone is made depressingly evident to many individuals that take finasteride (Proscar, Propecia) for prostate hypertrophy or male pattern baldness. In a considerable portion of these individuals a loss of libido and sexual function is experienced as a side effect, this despite a slight increase in circulating testosterone. anabolic steroid books Npc bodybuilding. Aromatase is the enzyme that catalyzes the conversion of androgens (androstenedione, testosterone) to estrogens. It also is found in certain areas of the brain in high concentration (often in conjunction with 5-alpha reductase), specifically in areas that are essential for the neuroendocrine control of gonadotropin secretion and sexual behavior. Androgens are well known to be essential to sexuality, but without the concomitant presence of estrogens they are essentially without effect. anabolic steroid books Apple cider vinegar diet. Studies have demonstrated that the abolition of estrogen formation through the use of aromatase inhibitors, or resulting from a congenital aromatase defect, greatly reduces sexual desire and function despite the presence of normal or high androgen levels. EAST GERMAN RESEARCHA group of East German scientists performed what is probably the most elaborate "practical" research on the psychological benefits of androgens. Their research did not center much on the prosexual effects of androgens, but rather on what they termed the "psychophysical" properties. The psychophysiological capacity, as the researchers describe it, is the ability of an individual to handle stress (physical, mental, and emotional). This capacity is determined by one's ability to activate appropriate centers in the central nervous system. Psychophysiological capacity can be evaluated by applying stressful stimuli and measuring shifts in the alpha-frequency of an encephalogram. Specifically, the researchers found that physical or psychic stresses lead to increases of approximately 4 to 6 Hertz compared to the starting value in individuals possessing the psychophysiological capacity to handle the particular stress. If the stress becomes excessive for an individual, the alpha frequency decreases after passing through the 4-6 Hertz optimum, and can then sink to levels below the original baseline. At the time that this research was carried out, there was a substantial government sponsored research effort in the field of athletic performance enhancement, and as you may have guessed, the aforementioned research was carried out on sportsmen. The alpha wave increase in athletes is associated not just with the physical stress of training or competition, but with the mental effort associated with preparation and the events themselves.
