'Testosterone' is reason women outlive men


Posted by Dr. Michael White, Updated on December 17th, 2017

Reading Time: < 1 minuteScientists said Monday they have new evidence about why women live longer than men, from a study of historical data showing castrated Koreans far outlived their non-eunuch contemporaries. The study, published in the scientific journal "Current Biology,'' used detailed genealogical records of the Imperial nobility during Korea's Joseon dynasty, which spanned more than 500 years from the late 1300s to the early 1900s. According to the data, most men, including kings and royal family members, died in their late-40s or early-50s. But noble-class eunuchs _ men who were castrated either by accident or because of social benefits _ lived, on … Read more »

Green tea could aid athletes hide testosterone doping


Posted by Dr. Michael White, Updated on December 16th, 2017

Reading Time: < 1 minuteLondon, Mar 25 : Green tea could inadvertently help athletes who dope on testosterone as it has been found to mask the hormone's presence in urine testing. Although testosterone is naturally present in the human body, unnatural amounts of it can be spotted by detecting its unusual ratio to another hormone called epitestosterone in urine. Declan Naughton and colleagues at Kingston University London conducted lab tests and discovered that compounds called catechins - found in green and white tea but not in black - inhibit an enzyme called UGT2B17. This enzyme attaches glucuronic acid to testosterone, making it more likely … Read more »

Reading Time: < 1 minuteTestosterone thought to cause 'man flu' Men have a reputation for being sooks when it comes to winter colds and flu but researchers believe "man flu" really does exist and the culprit is testosterone. US and French scientists have found evidence that testosterone plays a key role in making men's immune responses more sluggish than women's. It has long been thought that women's immune systems are generally stronger and respond more quickly to infections and vaccinations than that of males, but the cause has been unknown. The new study blames testosterone for dampening the immune response, suggesting men with high … Read more »

By that point, many men are working hard to keep their testosterone (or "T") levels high with supplements, diet, and exercise, but there are a few things you might be doing to unintentionally hinder your efforts.
