To test this, we administered contraceptive doses of testosterone to groups of young (3 months old) and middle-aged (13 months old) Brown Norway rats via Silastic implants to suppress endogenous Leydig cell testosterone production. steroid use in the nfl Quality-vet-steroids. After 8 months, the implants were removed, which rapidly (days) restores the ability of the previously suppressed Leydig cells to produce testosterone. Two months after removing the implants, when the rats of the two groups were 13 and 23 months of age, respectively, the Leydig cells in both cases were found to produce testosterone at the high levels of young Leydig cells, whereas significantly lower levels were produced by the 23-month-old controls. Thus, by placing the Leydig cells in a state of steroidogenic "hibernation," the reductions in Leydig cell testosterone production that invariably accompany aging did not occur. steroid use in the nfl Food fat carbohydrates protien chart. If hormonal contraception in the human functions the same way, the adverse consequences of reduced testosterone in later life (osteoporosis, reduced muscle mass, reduced libido, mood swings, etc. ) might be delayed or prevented. Discussion:OK, I will admit that I am biased about the use of androgens. steroid use in the nfl Quick weight loss for teens. Frankly, I think politicians and the popular press have unjustly vilified them. This being the case I tend to take notice to studies involving androgens. This particular study was a real surprise. Male aging is accompanied by reduced testosterone production by the Leydig cells, the testosterone-producing cells of the testis. The mechanism by which this occurs is unknown. In the above study they suppressed testosterone production with androgen implants in male rats for eight months. The researchers called this behavior of the testes as "steroidogenic hibernation". This is the same phenomenon that all male bodybuilders experience when using testosterone of other androgens.
