Can Lactic Acid Stimulate Testosterone?
The absent response of LH to an acute bout of resistance exercise despite an increase in testosterone has led researchers to speculate other mediators are influencing testosterone production. Possible mechanisms for increasing testosterone levels during high intensity exercise are due to increased circulating lactic acid levels that are being produced from high intensity training. Lactic acid has been shown to stimulate testosterone release in vitro (i.e. which means in the test tube)11. Researchers exposed the testosterone producing portion of the cell (i.e. Leydig cells) to lactic acid and found that administration of lactic acid dose-dependently increased the basal testosterone production. Testosterone Stimulation thru Adrenaline? Catecholamines or adrenaline is a possible stimulator of testosterone in men as well. It has been reported that men competing in competition and win have increased testosterone production which is also takes place with large increases in adrenaline which m
