Testosterone Benefits Testosterone has many beneficial effects, including increasing bone strength and density, inducing the creation of red blood cells, improving sexual function, enhancing libido, protecting the heart and increasing muscle strength in men and women. Testosterone and other steroid hormones are cleared from the body through the liver. The pathway that clears testosterone is called Glucuronidation. The enzyme responsible is called UDP-glucoronosyltranserase (UGT2B17). Once testosterone has circulated in the body and worked its magic, it goes to the liver to be excreted through the Glucuronidation pathway. Once here, it is converted into testosterone glucuronidase and then is excreted out of the body through the Kidneys primarily. How Your Diet Makes an Impact In 2012 and 2013, researcher Carl Jenkinson et al conducted studies published in Medical Journals (Frontiers of Endocrionology, Nutrition Journal and Steroids), demonstrating the Effects of Dietary Components on Testosterone Metabolism via UDP-Glucuronosyltransferase (UGP). What they found was that red wine samples inhibited the glucuronidation of testosterone by up to 70% over 2 hours. The ethanol content had no significant effect. They went on to discover that green and white tea preparations inhibited the UGT2B17 enzyme by circa 20% with a white tea powder inhibiting glucuronidation by...
