(Article CREDITS: The Stimulatory Effects of Cordycepin on Testosterone Production (Leydig Cell Steroidogenesis) : MushroomSupplements ")
Many studies, including one of human male infertility, indicate that Leydig cell function loss and sperm production decreases are due to drops in the testosterone concentration in blood. Thus testosterone is essential to male reproduction. In fact, we have found that oral administration of Cordyceps sinensis and its fractions increased plasma testosterone levels in both immature and mature B6 mice.
Here we explain that cordycepin stimulated immature B6 mice plasma testosterone production accompanied by increasing testis weight, which suggests that cordycepin is the bioactive pure material of Cordyceps regulating Leydig cell function.
Cordycepin in mainly found in Cordyceps militaris fruiting body extracts. Levels of over 1% are possible in supplements.
